1, poor contact between battery wire and motor wire. The electric vehicle has been used for a long time, and the battery cable is easily disconnected due to vibration and line aging; In addition to the fixing screws, the motor wire will be loose, and the motor wire connector will often burn out because of long-term overheating. In short, these main lines should be firmly connected, and they can't be connected for nothing, otherwise they will shake when starting, make a lot of noise, and even have a weak load, so they can't walk.

2. The motor hall is broken, and so is the controller. If this place is broken, it may lead to normal idling and the load will not go up. Among them, the motor hall is the easiest to check: plug in the car repair treasure, slowly push the motor and observe the hall indicator light; If all three lights are flashing normally, the hall is normal, otherwise, it is broken. The inspection method of the controller is not mentioned here, and the elimination method is usually used to replace it with a new one. _

3. The battery is low, and it is broken. Sometimes it is easy to ignore the power supply problem in maintenance, which may be that the battery is broken and the line contact is not good. The electric car is left for a long time, which leads to the loss of battery power. Look at the power of the meter first; The power cord is poorly connected somewhere. The above is the solution to the idle boring normal load of Inbor controller.
