Eelectrical power is displayed incorrectly

[Kapitaen31]

Describe the problem

For me, the electrical power and current are displayed too small by a factor of 2. This is when loading and unloading. I don't know where I can change that. Can you help me?

Any other information that may be helpful

Never heard of that. In the BMS the current is displayed correctly?

[Kapitaen31]

i had check it now. but is the same..

[mr-manuel]

Is the same as the driver shows or it‘s the same as it should be? Since the driver shows the same as the BMS os reporting you have to fix that in the BMS, since this will also reflect in wrong SOC and other values. If you don‘t know how, then contact your BMS seller.

[Kapitaen31]

the same as the driver. OK, I will then contact the seller. Thank you.
