Control of charge settings

There are 3 states for charging:

1. IDLE
2. START Charging - Enables the Charging Process. The charging starts only if the vehicle accepts it (e.g. the battery is not yet fully charged or below the defined max state of charge)
3. STOP Charging

The charge current can be set, too. However, there are 2 registers for defeining the max charge current which may interact if not set properly.

• B
• C

Remark: External charging control software
