Safety Instructions

Caution

To avoid personal injuries and damage to property you have to read and understand the following safety instructions and hazard warnings prior to installation and use of this ECU. Keep this documentation always near the ECU.

Proper Use and Intended Purpose

Caution

The ECU may only be operated according to the instructions and descriptions of this manual. The ECU is exclusively designed for use by skilled personnel as its operation may result in serious personal injuries and damage to property. Therefore, only those persons may operate the ECU who have understood the possible effects of the actions which may be caused by the ECU. Users have to be specifically trained in the handling (e.g. calibration) with the ECU, the applied embedded software and the system intended to be influenced. Users must have sufficient experience in using the ECU safely.

Hazard Warnings

Caution

The ECU may control and/or otherwise influence the behavior of control systems and electronic control units. Serious hazards for life, body and property may arise, in particular without limitation, by interventions in safety relevant systems (e.g. by deactivation or otherwise manipulating the engine management, steering, airbag and/or braking system) and/or if the ECU is operated in public areas (public traffic). Therefore, you must always ensure that the ECU is used in a safe manner. This includes inter alia the ability to put the system in which the ECU is used into a safe state at any time (e.g. by “emergency shutdown”), in particular without limitation in the event of errors or hazards. Furthermore, all technical safety and public law directives which are relevant for the system in which the ECU is used must apply. Provided that serious hazards for life, body and property may occur and before the use in public areas the system in which the ECU is used must be tested according to recognized rules of engineering in a non-public area.

1 General

The Vector Controller - Electric Vehicle Communication Controller (VC-EVCC) is a generic

ECU for 24V environments.

It realizes electrical charging according to DIN SPEC 70121 see [1] and ISO 15118 see [5]

for power line communication (PLC) with the infrastructure.

The hardware is the VP-EVCC with an integrated flash bootloader. VC-EVCC includes a modern MICROSAR stack with all relevant application modules to realize electrical charging

communication.
