The weather is hot, how to avoid spontaneous combustion of electric vehicles? How to check?

The weather is getting warmer and the battery capacity of electric vehicles is "recovering". The electric car, which is not far away, may be able to run further with the increase of temperature, but the hot weather will also bring harm to the battery of the electric car. Summer is the period of high spontaneous combustion of electric vehicles. When the weather is hot and the temperature rises, the probability of electric vehicles "catching fire" is high. Let love go home. The electric car mall recommends that you pay attention to prevent spontaneous combustion of electric vehicles in advance:

First, spontaneous combustion during charging.

1, charging reason. Because the charger is not matched, the charger is inferior, the charging cable is aging, the charger cover leads to poor heat dissipation, and the accumulated heat causes the house to burn down!

2. The battery of electric vehicle is aging. The battery of electric vehicle has been used for about two years, so it is easy to change the green light. Running a red light for a long time causes the battery heat to get out of control, and the heat that causes the electric vehicle battery to heat and expand gathers in the battery box of the electric vehicle to help "self-immolate"!

3. The battery cables of electric vehicles are relatively thin. Never connect the battery cable of an electric vehicle with a thin wire. If the working current is large, the wire will catch fire. When replacing the battery of the electric vehicle, replace the old connecting wire!

4. It is forbidden to charge in the sun. The weather is getting warmer and the temperature is high. Direct charging in the sun not only affects the charger, but also does great damage to the battery of electric vehicles. Due to the high temperature, the generated heat makes the current too large, which is easy to dissipate heat badly and flammable!

5. It is forbidden to use foam barrier inside the battery of electric vehicle! Some electric vehicle maintenance personnel use foam pads to prevent batteries from bumping, which is wrong! Once the battery of the electric vehicle is short-circuited, it will "spark" and the charging and heating will be out of control ... The foam has become a "helper" that causes the house to burn down!

6, charger fan failure. The charger generates heat when it works. If the charger fan doesn't turn, it will generate more and more heat, causing the house to catch fire! It's very hot. Check whether your charger is normal.

Second, riding spontaneous combustion: most of the spontaneous combustion during driving is related to the line.

1, the power cord of the controller is in poor contact. The current will increase when starting, and there will be sparks and fire when there is virtual connection!

Solution: Always check whether the motor wire and power cord are burnt out. If there is any treatment, it is best to weld them together to make the contact more real!

2. The power cord is short-circuited due to friction. The uneven riding road surface will lead to friction between wires in the electric vehicle, damage the insulation layer, cause short circuit, spark, high temperature and easy spontaneous combustion!

Solution: check the places where the line may be worn, such as the steering position of the front handlebar, the shock absorption side, and under the pedal pad ... If it is worn, please fix it with a wire harness so that it will not "rub"!

3. Poor contact of simple socket! Some simple electric cars charge and discharge through a hole. There will be a virtual connection "burning head" when riding an electric car in the wrong place!

Because the phenomenon of "spontaneous combustion" of electric vehicles is common, it is mainly caused by unscientific use. Paying more attention to maintenance at ordinary times can eliminate the risk of spontaneous combustion. Not only cars need maintenance, but also electric cars need maintenance and care.
