Overview

The RemoteStartTransaction command allows the Central System to initiate a charging session remotely (e.g., via mobile app).

When Received

User requests charging start via mobile app
Automated charging triggered by tariff schedules
Integration with fleet management systems

Expected Response

The CP responds with:

status: Accepted or Rejected

What Happens After Acceptance

CP authorizes using provided idTag
CP starts transaction on specified or available connector
CP sends StartTransaction message
Normal charging session proceeds

Usage Notes

If connectorId is omitted, CP selects an available connector
Provided idTag is used for StartTransaction
chargingProfile (if provided) defines power limits for this session
CP must validate idTag locally or via Authorize

Best Practices

Connector availability - Check connector status before sending
Authorization - Ensure idTag is valid and authorized
User feedback - Notify user of acceptance/rejection via app
Timeout handling - Handle cases where CP doesn’t respond
Charging profiles - Use profiles for smart charging and load management

Testing Tips

Test with specific connectorId
Test with omitted connectorId (auto-select)
Test with unavailable connector to verify rejection
Test with invalid idTag
Test with chargingProfile included

Common Errors

`GenericError`

Cause: Connector already in use

Solution: Ensure connector is available before remote start

`PropertyConstraintViolation`

Cause: Invalid connectorId

Solution: Use valid connector ID or omit for auto-selection
