Purpose

Provide the firmware every charger runs on: the real-time OS layer, bootloader and OTA client, the charging-protocol stack (ISO 15118, OCPP client), and the hardware abstraction for the HW Base control board. One firmware base serves three teams.

Key Responsibilities

  • Own the firmware base, its release train and its security updates.
  • Provide the protocol stack to Wallbox and DC Charger, and the device side of OTA and telemetry to Connectivity.
  • Keep the hardware abstraction in step with HW Base control-board revisions.

Customers and Deliverables

  • Wallbox and DC Charger — a versioned firmware base to build product firmware on.
  • Connectivity — the device-side protocol and OTA client the backend talks to.

Dependencies

Depends on HW Base for control-board revisions and test hardware, and on System Integration for protocol conformance test slots.

Key Challenges

  • Three customers: the product lines want features, Connectivity wants protocol stability, and a security fix has to reach all of them in one OTA wave.

Key Metrics and Monitoring

  • Base firmware releases per PI; protocol conformance findings; time to patch a security issue across the fleet.

Evaluation Schedule

## Purpose


Provide the firmware every charger runs on: the real-time OS layer, bootloader and OTA
client, the charging-protocol stack (ISO 15118, OCPP client), and the hardware abstraction
for the [[HW Base]] control board. One firmware base serves three teams.


## Key Responsibilities


- Own the firmware base, its release train and its security updates.
- Provide the protocol stack to [[Wallbox]] and [[DC Charger]], and the device side of OTA
  and telemetry to [[Connectivity]].
- Keep the hardware abstraction in step with [[HW Base]] control-board revisions.


## Customers and Deliverables


- [[Wallbox]] and [[DC Charger]] — a versioned firmware base to build product firmware on.
- [[Connectivity]] — the device-side protocol and OTA client the backend talks to.


## Dependencies


Depends on [[HW Base]] for control-board revisions and test hardware, and on
[[System Integration]] for protocol conformance test slots.


## Key Challenges


- Three customers: the product lines want features, Connectivity wants protocol stability,
  and a security fix has to reach all of them in one OTA wave.


## Key Metrics and Monitoring
