Electric Vehicle App Development Company
Digixvalley develops connected electric vehicle applications for charging-network operators, e-mobility providers, fleet teams, site hosts, charger businesses, and mobility product teams.
The approved platform may include driver applications, operator portals, station discovery, charging-session controls, tariffs, payments, fleet dashboards, protocol integrations, reporting, and administration.
Each project begins by identifying who operates the network, which chargers and systems are involved, where session data comes from, which protocol versions are supported, and what belongs in the first release.

Choose the Right EV Product Model
Select the operating model before selecting features. A driver app connected to an existing charging network has different users, integrations, and responsibilities from a new charging-station management system or fleet-depot platform.
EV Product Model | Main Users | Core Responsibility | Important Boundary |
|---|---|---|---|
EV charging driver app | Drivers and customer-support teams | Find stations, review connectors and tariffs, authorize sessions, pay, and access receipts | Charger information depends on the connected CPO, CSMS, roaming service, or data provider |
E-mobility service-provider app | Drivers and eMSP operations | Manage accounts, tokens, roaming access, sessions, tariffs, payments, and support | The eMSP may not own or operate the charging hardware |
CPO or CSMS platform | Charging-network operators and support teams | Monitor chargers, control sessions, manage faults, tariffs, access, and reporting | Charger compatibility depends on supported OCPP versions and functional profiles |
Fleet and depot charging platform | Fleet managers, drivers, and depot operators | Coordinate vehicles, chargers, priorities, departure needs, and site capacity | Optimization depends on available vehicle, charger, route, and energy data |
Site-host charging portal | Property owners and facility teams | Review usage, station status, access, revenue, and operational incidents | The site host may not control the full charging network |
Residential charging app | Residents, charger owners, and property managers | Configure access, schedules, charging sessions, shared use, and billing | Charger connectivity and electrical-capacity constraints affect the scope |
Technician application | Field technicians and network operations | Receive incidents, inspect chargers, document work, and close maintenance tasks | Remote diagnostics depend on charger and CSMS access |
OEM-connected EV app | Vehicle owners and connected-service teams | Display charging status, range, location, and available vehicle information | Vehicle data requires approved OEM, telematics, or onboard-system access |
A focused first release should solve one clear operating problem. Combining public charging, roaming, fleet optimization, residential charging, Plug & Charge, technician operations, and bidirectional energy functions in one MVP can add unnecessary dependencies.
How an EV Charging Session Works
An EV application is one interface within a wider charging ecosystem. It does not independently control every charger, calculate every tariff, or create every session record. A typical charging journey may follow this sequence:
1 | Station discovered |
2 | Connector, access, status, and tariff reviewed |
3 | Driver or vehicle authorized |
4 | Cable connected |
5 | Charging start requested |
6 | Session begins |
7 | Status and meter values received |
8 | Session stops or completes |
9 | Charge detail record generated |
10 | Final amount calculated |
11 | Payment or invoice processed |
12 | Receipt issued and records reconciled |
Connect the Correct Systems
A driver application normally communicates with a platform backend. That backend may exchange information with an eMSP, CPO, roaming platform, charging-station management system, payment provider, or another authorized service.
The charging station communicates with the approved management environment. The vehicle communicates with the charging equipment through the supported vehicle-to-EVSE interface.
Make Every Session State Visible
- Authorization rejected
- Remote-start timeout
- Charger fault
- Vehicle did not begin charging
- Session record delayed
- Payment failed
These are core product states, not informal support issues.
Preserve the Source of Every Record
Station status, tariffs, session events, meter values, payments, and receipts may come from different systems.
The platform should retain enough source and timestamp information to identify whether a record is current, delayed, estimated, externally supplied, or waiting for reconciliation.
What Digixvalley Builds
The final deliverables depend on the EV product model, network ownership, charging hardware, integrations, payment model, and operational responsibilities.
Driver and Customer Applications
01Driver and Customer Applications
- Account and vehicle profiles
- Station and connector discovery
- Access and tariff information
- Session authorization and monitoring
- Payment methods and receipts
- Support and incident reporting
The interface should clearly distinguish available, occupied, reserved, faulted, offline, unknown, and inaccessible chargers.
Digixvalley mobile app development services can support native or cross-platform driver experiences where mobile delivery matches the approved product requirements.
Operator and Site Portals
02Operator and Site Portals
- Station and connector monitoring
- Session review
- Tariff configuration
- User and access management
- Incident handling
- Operational reporting
Site-host views can be limited to the stations, usage, revenue, access policies, and incidents relevant to each property.
Browser-based operational tools can be delivered through Digixvalley web application development services.
Fleet and Technician Interfaces
03Fleet and Technician Interfaces
Fleet applications may support vehicle readiness, charging priorities, depot allocation, incomplete-session alerts, and departure planning.
Technician tools may provide fault assignments, charger information, inspection records, photographs, parts used, resolution notes, and maintenance history.
Backend, Integrations, and Administration
04Backend, Integrations, and Administration
- Accounts, roles, and permissions
- Charging-session services
- Tariff and payment logic
- Network and protocol adapters
- Notifications and reporting
- Monitoring and audit events
Digixvalley backend development services can support APIs, session states, integration adapters, administration, and reporting components.
Review Relevant Product Delivery Experience
Digixvalley’s published case studies show broader experience with mobile products, maps, real-time workflows, role-based platforms, payments, backend services, and operational dashboards.
These capabilities are relevant to connected mobility products. Mobility experience should not be presented as proof of OCPP, OCPI, charging-hardware, CSMS, or fleet-charging delivery unless those responsibilities are verified for the specific project.
When evaluating EV development experience, request evidence showing:
- The product and operating model
- Driver, operator, fleet, or technician interfaces
- Charging systems and hardware involved
- Protocol versions and integrations
- Session and payment responsibilities
- Testing environments and project status
Relevant evidence should be described by its verified scope rather than by broad industry labels.
Manage Stations, Connectors, Availability, and Tariffs
A station appearing on a map does not guarantee that every connector is working, compatible, accessible, or available to the current driver. The product needs an explicit source-of-truth model for locations, chargers, connectors, status, tariffs, and access rules.
Configurable and Custom Delivery Options
- Address and coordinates
- Site operating hours
- Connector types
- Charging power
- Access restrictions
- Network or operator
- Tariff information
Explain What “Available” Means
A connector may be technically available but unavailable to a specific driver because of reservation, membership restrictions, connector incompatibility, site access, operating hours, or roaming eligibility. Display the data source and last meaningful update where delayed or stale information could affect the charging decision.
Treat Reservations as Conditional
Reservation support depends on the charging operator, charger or CSMS capability, protocol implementation, time-window rules, and commercial policy.
- Who can reserve
- Which connectors qualify
- When the reservation expires
- What happens after late arrival
- How conflicts and cancellations are handled
Preserve Tariff Context
A displayed tariff may include energy, time, session, idle, tax, membership, or roaming components. The application should identify which party supplies the tariff, when it became effective, and whether the displayed amount is an estimate or a final calculated charge.
Connect Charging Systems and Protocols
Protocol selection should follow the systems that need to exchange information. Protocol names should not be added merely as technology labels.
Interface or Standard | Main Relationship | Typical Responsibility |
|---|---|---|
Mobile and web APIs | Driver, operator, fleet, or technician interface <-> platform backend | Accounts, station search, session controls, payments, support, and reporting |
OCPP | Charging station <-> charging-station management system | Authorization, transactions, status, meter values, commands, faults, configuration, and device management |
OCPI | CPO <-> eMSP or roaming platform | Locations, tariffs, tokens, sessions, commands, charge detail records, charging profiles, payments, and supported booking functions |
ISO 15118 | Electric vehicle <-> charging equipment | Vehicle-to-EVSE communication, authorization, charging control, and supported bidirectional functions |
OEM or telematics API | Vehicle-data provider <-> platform backend | State of charge, location, range, odometer, charging status, and available diagnostic information |
OCPP and Charging-Station Management
OCPP defines communication between charging stations and charging-station management systems. It is not normally the direct communication layer of the driver’s mobile interface.
The Open Charge Alliance publishes OCPP 1.6, OCPP 2.0.1, and OCPP 2.1. OCPP 1.6 and OCPP 2.0.1 use different application logic and are not compatible. OCPP 2.0.1 adds expanded device management, transaction handling, security, smart charging, and ISO 15118-related support. OCPP 2.1 builds on 2.0.1 and adds areas including bidirectional charging, DER control, battery swapping, and additional payment functions.
Before approving OCPP scope, confirm:
- Charger manufacturer and model
- Existing OCPP version
- Required commands and functions
- Security profile
- Certification requirements
- CSMS responsibility
Integration Failure and Reconciliation
- Timeouts and retries
- Duplicate events
- Authentication renewal
- Record matching
- Stale-data warnings
- Manual correction
- Vendor outages
- Version changes
When an external platform is unavailable, the application should show an accurate pending, delayed, or unknown state rather than presenting old information as current.
OCPI and Roaming
OCPI supports automated information exchange between charge point operators and e-mobility service providers. The current official release is OCPI 2.3.0, published as a core specification with separately packaged modules.
An OCPI project should define which parties exchange locations, tokens, tariffs, sessions, commands, charge detail records, payments, or bookings where supported.
Commercial agreements, credentials, testing, and production onboarding remain separate from the technical implementation.
ISO 15118 and Vehicle Communication
ISO 15118-20:2022 defines communication between an electric vehicle and electric vehicle supply equipment, including application messages and sequences for charging and supported bidirectional power transfer.
ISO 15118 should only appear in the project scope where the vehicle, charger, certificates, backend, and selected implementation support the required functionality.
Control Authorization, Sessions, Payments, and Reconciliation
A completed charging journey may involve identity, network authorization, charger commands, meter values, tariff calculation, payment, and settlement across several organizations. These responsibilities should be separated in the architecture.
Authorize the Driver or Vehicle
- Mobile account
- RFID token
- QR code
- Roaming credential
- Payment terminal
- Supported vehicle-based authorization
The platform should record which system approved or rejected the request and avoid showing a session as active until the charging network confirms the relevant state.
Manage the Charging Session
- Station and connector
- Driver, token, or vehicle
- Start and stop times
- Meter values
- Interruptions and suspensions
- Remote commands
- Final energy delivered
If a command times out or meter values stop arriving, the interface should identify the uncertainty instead of inventing a completed state.
Calculate and Collect Payment
- Tariff selection
- Estimated cost
- Payment authorization or wallet check
- Completed session information
- Charge detail record
- Final charge
- Receipt or invoice
- Refund or dispute handling
Card payment, subscriptions, fleet invoicing, prepaid balance, and roaming settlement require different business rules.
Reconcile Charging Records
The station, CSMS, CPO, eMSP, roaming service, and payment provider may hold related but different records.
- Missing sessions
- Duplicate records
- Meter-value differences
- Tariff mismatches
- Delayed charge detail records
- Payment discrepancies
The system should preserve the original records and correction history rather than silently overwriting financial or charging information.
Coordinate Fleet and Depot Charging
Fleet charging is not only a station-monitoring dashboard. The platform must help operations teams determine whether vehicles will be sufficiently charged for their next assignment.
Build a Vehicle-Readiness Model
- Vehicle identity
- Current state of charge
- Required departure time
- Expected route energy
- Assigned charger
- Charger power
- Estimated charging duration
Prioritize Charging Within Site Constraints
A depot may have more connected vehicles than the site can charge at full power simultaneously.
- Departure priority
- Required energy
- Charger availability
- Site capacity
- Charging windows
- Incomplete-session alerts
Handle Incomplete Charging
- Vehicle connected late
- Charger fault
- Power restriction
- Session interruption
- Incorrect assignment
- Data loss
Handle Faults, Offline States, and Security
Charging products must remain understandable when hardware, mobile connectivity, external services, or payment systems do not behave as expected.
Failure | Driver Experience | Operator Response |
|---|---|---|
Stale charger status | Display source and timestamp | Refresh or investigate the data feed |
Authorization rejected | Confirm that charging did not start | Review account, token, roaming, or eligibility |
Remote-start timeout | Keep the session inactive or pending | Check charger and CSMS responses |
Meter values stop | Mark session information as incomplete | Compare station and backend records |
Charger fault | Provide safe alternative guidance | Create and assign an operational incident |
Payment failure | Preserve the charging record | Retry, invoice, or route to exception handling |
Support Weak or Lost Connectivity
The mobile application should clearly show which actions require a live connection.
Where appropriate, the experience may preserve station details, recent sessions, support information, or pending actions without claiming that a charger command succeeded before receiving confirmation.
Protect Commands and Credentials
- Strong user and operator authentication
- Role-based access
- Secure API and secret management
- Certificate and key handling
- Command authorization
- Audit events
An operator who can change tariffs or remotely control chargers requires different permissions from a driver, site host, support user, or field technician.
Plan Monitoring and Recovery
- Failed commands
- Offline chargers
- Protocol errors
- Payment exceptions
- Delayed records
- Integration availability
Recovery procedures should identify who investigates each failure and how affected sessions, charges, and customer communications are resolved.
Define the MVP, Optional Modules, and Scope
A focused MVP should validate one complete charging or operational journey without hiding important session, payment, status, and failure states.
Area | Focused MVP | Expanded EV Platform |
|---|---|---|
Users | One primary driver or operator audience | Drivers, CPOs, eMSPs, fleets, sites, and technicians |
Network | One CPO, CSMS, or approved data source | Multiple operators, roaming, and partner networks |
Protocols | Existing API or one defined OCPP scope | Multiple OCPP versions, OCPI, vehicle, and energy integrations |
Sessions | Authorization, session status, and history | Remote controls, roaming, complex failures, and reconciliation |
Payments | One payment or invoicing model | Wallets, subscriptions, roaming, fleet billing, refunds, and disputes |
Fleet | Limited or excluded | Vehicle readiness, depot priorities, and power constraints |
Hardware | Defined charger models | Multi-vendor and multi-version support |
Operations | Essential monitoring and support | Incidents, diagnostics, maintenance, and advanced reporting |
Optional Modules
- Charger reservations
- Roaming
- Smart charging
- Home-charger commissioning
- Fleet prioritization
- Technician workflows
Each module remains conditional on hardware, network, protocol, data, commercial access, and operating responsibilities.
Vehicle and Energy Functions
Plug & Charge, bidirectional charging, site-energy management, demand response, and advanced load control require deeper vehicle, charger, certificate, energy, and infrastructure coordination.
These functions should not be added to a standard driver-app proposal without technical discovery.
Scope and Investment Factors
- Product model and user roles
- Charging networks and hardware
- Protocols and versions
- Payments and tariffs
- Roaming
- Fleet or site requirements
A useful estimate requires confirmed interfaces, transactions, test environments, responsibilities, and first-release priorities. Fixed public pricing cannot represent every EV platform.

Develop, Test, and Launch the Platform
EV development should account for hardware, protocols, external systems, charging states, and operational failures—not only mobile screens.
Product and Network Discovery
- Product model and target users
- CPO, eMSP, CSMS, and site responsibilities
- Charger manufacturers and models
- Protocol versions
- Payment and tariff ownership
- Fleet or vehicle-data needs
This stage separates required functionality from assumptions that depend on external access.
Architecture and Experience Design
The approved model becomes driver, operator, fleet, technician, site-host, and administration experiences.
- Session and command states
- System ownership
- Integration adapters
- Security and permissions
- Reporting and monitoring
- Failure recovery
Where several platforms require one shared product experience, Digixvalley may evaluate its cross-platform app development services.
Development and Integration
Engineering may include mobile applications, web portals, backend services, APIs, charging-system integrations, payment services, notifications, reporting, and administration.
A named protocol, charger, or vendor should enter the approved scope only after compatibility and access requirements have been reviewed.
EV-Specific Testing
- Supported chargers and connectors
- Authorization approval and rejection
- Session start, interruption, and stop
- Meter-value delays or loss
- Status freshness and offline states
- Tariff, CDR, and receipt consistency
Where physical chargers are unavailable, approved simulators may support part of the test process, but simulated coverage should not be presented as full hardware validation.
Launch and Handover
Launch preparation may include infrastructure, monitoring, payment configuration, network credentials, app-store materials, operating procedures, integration approval, and controlled rollout.
Repository access, infrastructure accounts, certificates, credentials, intellectual-property terms, maintenance, and support should follow the signed agreement.
Post-launch work can be planned through Digixvalley application maintenance and support services.

Frequently Asked Questions
Digixvalley can plan driver charging apps, eMSP products, CPO or CSMS interfaces, fleet and depot charging platforms, site-host portals, residential charger apps, technician tools, and connected vehicle experiences. The appropriate model depends on who operates the network, the target users, chargers, backend systems, protocols, payments, and data sources.
Usually, the mobile application communicates with a platform backend. OCPP primarily connects charging stations with a charging-station management system. The exact architecture depends on the charger, CSMS, network operator, protocol version, and available APIs.
OCPP supports communication between a charging station and its management system. OCPI supports information exchange between charge point operators, e-mobility service providers, and roaming relationships. It may exchange locations, tariffs, tokens, sessions, commands, and charge detail records.
ISO 15118 is relevant when the project involves supported communication between the electric vehicle and charging equipment. Its use depends on the vehicle, charger, certificates, backend environment, and required authorization or charging functions.
Potentially. The accuracy and freshness of charger status depend on the CPO, CSMS, roaming feed, station directory, or another approved source. The application should show delayed or unknown data accurately rather than guaranteeing that every displayed status is current.
Yes, where the operator, charging system, protocol implementation, and business rules support reservation. The project must define eligible chargers, reservation windows, expiry, cancellation, conflicts, and late-arrival handling.
Potentially. Multi-network access may involve direct CPO integrations, roaming services, OCPI, commercial agreements, credentials, testing, and production onboarding. The required networks and transactions should be confirmed during discovery.
Yes. Fleet scope may include vehicle readiness, charger allocation, departure priorities, incomplete-charging alerts, and site-capacity constraints. Vehicle state-of-charge and diagnostic information require an approved OEM, telematics, gateway, or other reliable data source.
The main factors are product model, users, charging networks, hardware, protocol versions, integrations, payments, roaming, vehicle data, fleet requirements, smart charging, testing, and availability expectations.
Repository access, infrastructure, app-store accounts, certificates, network credentials, documentation, intellectual-property rights, monitoring, maintenance, and support responsibilities should be defined in the signed agreement.
Plan Your EV Application
A successful EV product needs more than a station map, payment button, and charging animation. It must connect drivers, charging networks, stations, management systems, tariffs, authorization, session records, payments, fleets, integrations, and operational failure states. Share your product model, target users, charger manufacturers, current CSMS or backend, protocol versions, roaming requirements, payment model, fleet needs, vehicle-data sources, target markets, and first-release priorities.
