How to prevent spontaneous combustion of electric vehicles in hot weather?

More and more people choose to ride bicycles, and electric vehicles are more popular. However, the spontaneous combustion of electric vehicles continues to occur, and everyone is very upset to see these. In fact, the spontaneous combustion of electric vehicles is nothing more than their own reasons and external factors when charging. Anyway, I hope everyone will pay attention to these situations for their own sake and for the safety of others.

For its own reasons, 1, the electric car has been used for a long time, and the connecting wires in the car are very easy to be brittle and short-circuited. According to professionals, the electrode connection wires in electric vehicles can generally withstand 20 amperes of strong current. If the transmission line in the electric vehicle has a short circuit fault and the external temperature is too high, it is very easy to produce spontaneous combustion. Therefore, in general, charging an electric vehicle under the scorching sun in summer will lead to a greater probability of short circuit failure and fire.

Reminder: the route is very fragile after a long time. Customers are advised to check at the after-sales service center on time within six months to one year. In addition, after riding a bicycle in hot weather, put the vehicle in the shade and wait for the temperature of the vehicle and its battery to drop before charging. ?

2, the battery is short-circuited, and the electric car is on fire. It is easy for everyone to attribute the cause to the battery. So will the battery explode? Take lead-acid batteries as an example. Lead-acid battery is actually a valve-controlled battery, and its interior is not completely sealed. Even if the internal temperature of the battery is high, resulting in a large amount of gas, which leads to the expansion of the internal working pressure of the battery. After the gas accumulates to a certain extent, it will be released according to the exhaust port, and it is not easy to have an explosion accident casually. ?

Unless the battery has a long service life, the internal circuit is very easy to short-circuit and cause fire. Another reason is that the battery installation is not standard. When many agents install batteries, because the battery box is installed too tightly, the electrode connecting wires cross or even are squeezed in the middle, which will cause short circuit failure and burning after long-term friction. ?

Reminder: According to relevant standards and specifications, the general service life of electric vehicle batteries is 1.5 years and 2.5 years. Therefore, customers are advised to remove and replace batteries on time, and must go to a reliable store to buy matching batteries. There is no need to choose fake batteries.

? 3. If the charger is not paired and electric car charger is not paired, it is very likely that the electric car will catch fire. Many families not only have an electric car, but also electric car charger of different famous brands. Never mix them, which will not only damage the battery of electric vehicles, but also bury potential safety hazards.

Reminder: chargers of different famous brands cannot be mixed. If the charger is damaged, please go to a reliable store to buy it. ?

External reason 1, too much charging.

Overcharging is also the key cause of electric vehicle fire. Generally speaking, an electric car can meet the customer's requirements after charging for eight hours. In specific cases, many customers let electric vehicles charge overnight 12 hours or even longer for better convenience, which will not easily produce positive practical effects, but will reduce the characteristics of batteries.

Reminder: Ensure the charging time of the electric vehicle, and immediately charge the battery when the power reaches 7080. Generally, charging is 68 hours in summer and 8 10 hour in winter. The battery is not suitable for overcharge and discharge. ?

2. Short circuit

Many customers who ride electric cars are migrant workers in big cities and live in small rented houses. There will be eight or nine households on the first floor. Everyone has an electric car and needs to be recharged at night. Charging several cars at the same time will cause short circuit, which is very easy to cause safety accidents. In addition, some people like to pull the cable to charge, which will also bury potential safety hazards.

Reminder: Never pull the cable privately, but charge it at a reliable electric vehicle charging place. ?

3, charging the natural environment

Look at these electric car fires, which usually happen in rooms, stairs and corridors on the first floor of engineering buildings. Because many customers' houses don't have exclusive charging places for electric vehicles, they have to store electric vehicles in stairwells, aisles or send them into rooms for charging. In the event of a fire accident of electric vehicles, flames and smoke will block the safety passage and escape passage of engineering buildings, which will easily lead to casualties and even serious safety accidents. ?

Reminder: Do not charge in stairwells, corridors and rooms to prevent potential safety hazards. Generally speaking, electric vehicles are actually relatively safe, and customers should do daily inspections to avoid common faults or poor contact. In addition, we should pay more attention to the natural environment for charging electric vehicles, and don't charge them in narrow and crowded indoor spaces. ?

Many communities have been marketing and promoting coin-operated electric vehicle charging stations and smart charging stations (using APP mobile phone software to pay for charging on mobile phones). At the same time, it also gives our electric car a lot of safety precautions during the whole charging process. Do you have any different views on this? Please leave a comment below.
