Question 3: The motor is powerless, running is not far, what reason?1. If your electric car motor always feels unable to run, it is likely because the motor controller is aging. The motor controller is aging, resulting in too small output power, causing power of electric machine.
2, the other case of electric vehicle motor is due to the magnetic steel demagnetization, so that the motor does not drive the moment, and the current is increased, and the power consumption is serious.
3, the coil short circuit or serious leakage, so that the electrical energy is converted to a large amount of thermal energy, the temperature is rapidly increased, which causes the motor to decrease, and the motor can be weak, or even damage the motor.
Question 4: What is the hot in the battery?
If you feel that your electric car is charging, the battery is always hot, it may be due to the high pressure of the charger.
If the charger voltage is high, the battery polar plate is accelerated, resulting in a post-charging of the electrolytic water reaction (generating H2 and O2), and the internal pressure of the battery increases, H2 and O2 leaks, resulting in loss of moisture. When the moisture is too much, the thermal out of control is generated inside the battery. The situation is dangerous. The battery will drum, if a plate break is generated, igniting H2 and O2 will explode.
Question 5: What is the cause of the charger?
Is there any of your charger, but it is not the green light? The reasons for the charger do not turn off the following 5 points:
1, the battery is too water for too much.
2, the charger voltage is higher, causing the current does not fall, resulting in severe fever, forming a vicious circle, the charger is always in the high pressure stage, no green light.
3. Add impurity liquids such as iron, manganese, copper, resulting in severe self-discharge of the battery, causing the charging current without falling. Will not turn green light.
4, there is a slight short circuit inside the battery.
5, the charger turning light is too low. The battery with a slight fault will cause no green light.
