What should I pay attention to when using electric vehicles in hot weather?

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. What should I pay attention to when using an electric car that day?

Spontaneous combustion during charging

1, charging reason. Due to the mismatch of chargers, inferior chargers, aging charging wires, and the cover of chargers, the heat dissipation is not smooth, and the heat accumulation causes a fire.

2, the battery connection line is thin. Never connect the battery cable with thin wires. If the working current is large, the wire will catch fire. When replacing the battery, please replace the old connecting cable!

3. It is forbidden to charge in the sun. Recently, the high temperature in many parts of the country, charging in direct sunlight not only affects the charger, but also does great harm to the battery. Because of the high temperature, the generated heat makes the current too large, which is easy to dissipate heat badly and causes accidents.

4, charger fan failure. The charger generates heat when it works. If the charger fan does not turn, it will generate more and more heat, and an accident may occur. It's very hot. Check whether your charger is normal?

The spontaneous combustion during driving is mostly 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 flames when virtual connection is made.

Solution: Always check the motor wire and power cord to see if there is any burnt place. If there is any treatment, it is best to weld with solder 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 ground, such as the steering position of the front handle, the side of shock absorption, and under the pedal pad. If it is worn, please fix it with wire harness to get rid of "friction".

3. Poor contact of simple socket. Some simple electric vehicles are all a "hole" when charging and discharging, and there will be a "burning head" when riding an electric vehicle incorrectly.

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.
