According to the fault types, it can be summarized into five types of faults, including BMS and charger communication failure, and the fault verification data are given. The authors of proposed a battery model-based monitoring and early warning method for electric vehicle charging faults.
Problem: Engine starts OK, but the battery does not stay charged. Solution #1: Focus on your battery first. If your vehicle has stopped running, jumpstart the engine, remove the jumper cables as quickly as possible, and wait. If the vehicle keeps running after a period of time, there’s likely a problem with your battery.
With the development of electric vehicles in China, the fault monitoring and warning systems for the charging process of electric vehicles have received the industry’s attention. A method for the monitoring and warning of electric vehicle charging faults based on a battery model is proposed in this paper.
Thermal fault The thermal abnormal in the battery system are called thermal faults, mainly including cooling system faults and abnormal battery temperature. The battery system must operate effectively within a specific temperature range, and high or low temperatures can affect the normal operation of the battery.
[Warning Light] Electrical circuit fault
Maybe a loose connection near the battery or an earth lead from the battery. Easiest check is with a multimeter or voltage tester and see if the battery is charging when the engine runs. Beyond that, I''d suggest getting a diagnostic check, probably Diagbox would be best to read any Citroen specific fault, maybe something like the Android Torque ...

How To Diagnose & Fix A Laptop That is Not Charging The Battery
If the battery circuit is not sending the correct voltage to the battery, then the fault lies with your battery. However, if the battery circuit is not sending the required voltage to battery then the problem lies with either your charging port or the charging circuit. In this case it''s highly likely that your charging port is broken so, don''t panic yet! Warning! If the issue lies with ...
