Battery: Ampera‐e 64 kWh - dalathegreat/Battery-Emulator GitHub Wiki

[!CAUTION] Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.

GM BEV2 platform

The 60-66kWh battery in the GM BEV2 platform can be found in the following vehicles

  • Opel Ampera-E (2017-2021)
  • Chevrolet Bolt (2016-2023)

2020+ models are 64 KWh, earlier are 57 kWh

Software setup

To use the Bolt/Ampera battery, enable the line #define BOLT_AMPERA_BATTERY setting in USER_SETTINGS

I use 3x this relais and it works https://nl.aliexpress.com/item/1005005622431177.html?spm=a2g0o.order_list.order_list_main.126.d91579d2FEesY4&gatewayAdapt=glo2nld

The battery uses 12V controlled contactors, so use CONTACTOR_CONTROL if you want Battery-Emulator to also control the contactors via GPIO

Wiring diagrams

The following diagrams will help you to connect to the CAN buses on the Opel/Chevy batteries:

[!NOTE] These batteries have multiple CAN buses that needs to be jumpered together to form one large CAN bus the resistor on the Lilygo must be removed Example, development environment with contactor control via GPIO, and all 3x CAN buses connected together as one single bus
