As we all know, the battery of an electric vehicle is very important to the whole vehicle. But in many cases, the problem of electric vehicles is not all the problem of the battery. If the electric car breaks down, or the headlights are on but cannot be started, what is the problem?
Maybe everyone will analyze that "the electric vehicle lights are on", indicating that the electric vehicle is not in a power-deficient state, and if the battery has electricity, the battery problem is ruled out...
But there is no problem with the battery, but the electric car cannot start. Why is this? After analyzing and sorting out, the following tips must be kept in mind:
First of all, when it is found that the electric vehicle cannot be started, of course, the battery must be checked first. At present, the common specifications in the market are 24V, 36V, 48V, 60V, 72V voltage, which can detect whether the output voltage of the battery is normal. If the voltage is too low, it is likely to be a battery problem and should be replaced in time.
Second, check whether the controller of the electric vehicle is normal. Generally speaking, it is easy to cause a short circuit of the controller circuit if the operation is improper. The correct way is to short-circuit the positive 5V of the turn handle line to see if it rotates. If it doesn't turn, the controller is more likely to have problems.
Furthermore, you can check whether the motor is in normal working condition. Everyone knows that the electric vehicle motor is a key component. If there is a problem, the electric vehicle will not work normally. The poor contact of the carbon brush of the electric vehicle motor will also cause the failure of the electric vehicle to start.
In addition, it is to check the brake line/signal line/brake switch of the electric vehicle. If the electric vehicle rotates during the short circuit, it means that the handlebar is broken and needs to be replaced or repaired in time.
The above are the most common reasons and analysis techniques for electric vehicles that are most commonly encountered by the majority of electric vehicle users. If the electric vehicle breaks down in the future, everyone can easily solve it!
