There may be many reasons for the failure of the power system of Changan UNI-T new energy vehicles
- Low-voltage battery is dead: Battery aging, battery failure or long-term use may cause the low-voltage battery to be dead, affecting the normal operation of the power system.
- High-voltage power battery system failure:
- Single cell failure in the battery pack: Single cells may have performance degradation, damage or internal short circuit, affecting the performance of the entire battery pack.
- Motor controller failure: The motor controller is a key component between the battery pack and the motor. Its failure may cause the power system to fail to work properly.
- Motor failure: Faults in the motor itself, such as winding damage and bearing wear, will also affect the performance of the power system.
- Fault code exists in the engine electronic control system: When the sensor, actuator or control unit in the engine electronic control system fails, a fault code may be generated, causing the power system to fail to work properly.
- Internal failure of the power manager: The power manager is responsible for the charge and discharge management of the battery pack. Its internal failure may cause the battery pack to fail to work correctly, thus affecting the power system.
- Drive motor controller failure: The drive motor controller is responsible for controlling the operation of the motor. Its failure may cause the motor to not work properly, thus affecting the vehicle’s power performance.
- High-voltage disconnection failure: The contactor inside the battery pack or the contactor in the distribution box is automatically disconnected, resulting in a serious failure of the high-voltage system, which requires timely maintenance.
- Power battery failure: It may be caused by a single cell failure inside the battery pack, a battery pack being hit, or poor contact of the internal circuit of the battery pack. You need to contact a professional for repair.
- Battery pack leakage: There is leakage in the high-voltage part of the battery, which may cause the vehicle to be unable to move, and the high-voltage output of the whole vehicle is cut off, requiring maintenance personnel to handle.
- No power in the whole vehicle: It may be caused by a burnt fuse, loose wiring plug, or damaged power switch. You need to check the relevant circuits and switches.
- Line and connector failure: Loose connection bolts between batteries will cause false battery connection failure, resulting in insufficient power of the car. You need to check the circuit and connector in time.
Please note that the above are just some possible reasons. The specific cause of the failure needs to be detected and judged in combination with the actual situation of the vehicle and professional diagnostic equipment. In case of power system failure, it is recommended to contact Changan Automobile official after-sales service or professional automobile maintenance personnel for inspection and repair in time.

We went down the lane, by the body of the man in black, sodden now from the overnight hail, and broke into the woods..
