Low-carbon life has become the main theme of people's life. The convenience of green electric vehicles in people's lives makes everyone choose “small electric shovel†in travel, but each electric vehicle is composed of various components. Some of them are indispensable. What is the starting, driving and stopping of an electric car? That is the electric vehicle controller.
Now Wanyuan Electric will explain the reasons for the failure of the electric vehicle controller.
1, power device damage
There are several possibilities for this part of the damage, one is the motor damage; the second is the quality of the power unit is unqualified; the third is that the device is not installed properly or the vibration during operation is loose due to its components; fourth, the motor is overloaded; Fifth, the power component drive circuit is damaged or the parameter design is unreasonable.
2. The internal power supply of the controller is damaged.
There are several possibilities for this problem. First, the internal circuit of the electric vehicle controller is short-circuited; second, the peripheral control unit is short-circuited; and third, the external lead is short-circuited.
3, the controller works intermittently
The controller works intermittently. Generally, there are several possibilities: the device itself drifts in high temperature or low temperature environment; the overall design power consumption of the controller causes the local temperature of some devices to be too high and the device itself enters the protection state; Poor contact.
4, the connection line is worn and the connector is bad or falling off, causing loss of control signal
The connection line is worn and the contact plug is not well contacted or dropped. Generally, there are several possibilities: the wire selection is unreasonable; the protection of the wire is not complete; the connector is not firmly crimped.
Wanyuan Electric reminds you that when there is a problem with your electric car, you can check this problem when you can't start it. The electric vehicle controller has the power to control the electric car. If there is a problem, it must be solved in time. Your happy life is easy to move forward.
