Byd charging red light charging alarm is a warning charging system failure. Specific performance in three aspects:
< br >
1, car charger failure;
< br >
2, line failure:
< br >
3. The BMS is faulty.

The solution: First detect the charger K154 connector, measure the K154-D voltage of 1.2V before the connector is removed, and measure 11.49V after the connector is removed. The change between the K154-C connector and the plug is not much more than 12.9V, and the resistance between the K154-E plug and the iron is 1.5 K154-E (the plug is almost pulled out or not). It's infinite when you draw the gun. Analyze the fault of the car charger, and remove the fault after replacement.
