FAQ: RT-BMS connection to chargers - the wiring of the pins

Please note that there is not any standard of the pins used at the charges to communicate with the BMS.  As seen from the two photos, there may be completely different wiring on different chargers. (Even on the same type of chargers but from different production time).  You always need to check against the information on the sticker at the connector. (Note: if the sticker was lost or removed, there is no way to confirm the wiring.)

FAQ: What type is the connector used at the charger to connect to BMS?

There is usually the Phoenix or WAGO type connector. (Wago 231-104-031-000). Take note that this connector is not designed for frequent manipulations. We suggest you can use other type of connectors that are designed for long life-time.
