10 experiences in preventing spontaneous combustion of electric vehicles

Tomorrow is three volts, which means the hottest time of the year has arrived. Hot weather, electric vehicles are also easy to lose their temper, especially batteries are not durable, easy to fill, and even spontaneous combustion accidents, seriously plagued many electric vehicle users. So what exactly is causing all this? In fact, as long as everyone can use the electric car scientifically and regularly, reasonable charging, more than 95 % of accidents can be avoided. Next, we summarize the 10 experiences of using electric cars and share them with you. Please also tell each other to prevent the problem in the future:

1 charger exposed to the sun

Summer is hot and charging in the sun. In the long run, the battery is easily filled and can cause spontaneous combustion when the situation is serious.

2 Charging in rain

In the summer, there are many rainwater in the South, chargers are flooded, and accessories for many electronic components are easily short-circuited and burned, causing safety hazards.

3 Charger not ventilated around

When the charger is working, it needs ventilation so that it has a good cooling environment. Otherwise, the heat dissipation is not smooth and the temperature is getting higher and higher. The fire situation also appears.

Charge immediately after 4 ride.

In the cycling state, the battery itself will heat up. In addition to the hot weather and the high temperature of the battery, charging the battery immediately after cycling will exacerbate the loss of water in the battery, reduce the service life of the battery, and increase the risk of battery filling. The electric car should be recharged more than half an hour after it is out of service.

5 Long charge, even overnight

Many electric car users often charge all night for the convenience of the picture. If the remaining batteries are more likely to cause overcharging, this will inevitably cause great damage to the battery, and even recharge the battery, causing a safety accident! For frequent overnight charging, a reliable timer with reliable quality can be purchased. In general, summer charging time is about 8 hours.

Power level 6 is used up.

Recharging the battery with electricity may cause excessive discharge, affect the service life, and even damage the battery.

7 charger for mixing

Different brands, different models, battery models are not the same, chargers are naturally different, can not be mixed. Some electric car users are used in the process of use, often mixed with the use of 60V chargers filled with 48V batteries, 20AH chargers filled with 12AH batteries, charging voltage and current do not match, will damage the battery.

8 Use of inferior charger

The electronic components of the inferior charger are all inferior materials, and the voltage and current are unstable, small and small, and easily damaged. The frequent problem is that the battery is full of electricity and does not turn the light, and the charging current can not be adjusted according to the current of the battery. A large number of batteries are overcharged, and the battery will be recharged after repeated overcharging.

9 Use of fast charging stations

The working principle of a fast charging station is to charge a large current for a short period of time, but it will cause serious water loss in the battery. Long-term use is also an important reason for battery filling.

10 charger with car

Some electric car users like to bring chargers to the car for easy charging. In fact, the electronic components on the main board of the electric car charger are welded. Some large electronic components may cause welding during bumps, resulting in poor contact. Causes current instability and failure of protection function during charging.
