What are the hidden dangers of electric vehicles in terms of batteries?

What are the hidden dangers of electric vehicles in terms of batteries? 1. Cooling system New energy vehicles, especially pure electric vehicles, rely on electric energy as a supply. But electric energy does not flow into the cooling system, so under high temperature conditions, electric vehicles are extremely prone to spontaneous combustion accidents. Even though many new energy vehicles now use water cooling, potential safety hazards still exist. 2. Squeeze collision After being squeezed or collided, the battery is also extremely prone to spontaneous combustion or explosion accidents. However, new energy vehicles driving on the road are bound to have a hidden danger of collision. The protection of the battery's anti-collision safety by various manufacturers is uneven, so there is still a chance for electric vehicles to be dangerous. 3. Charging problems The charging problems of pure electric vehicles also have certain safety hazards, especially when a small short circuit occurs inside the battery, new energy vehicles are prone to fire. If charging for a long time will also cause the battery to overheat, etc., at this time, the car owner should carry out the correct charging according to the vehicle's instructions. Advantage 1: Long life of lithium-ion battery, light weight and small size. The power performance of lithium-ion battery electric bicycles is similar to that of lead-acid batteries (simple electric bicycles). It can be charged for 6 to 8 hours and can run 30 to 45 kilometers depending on the battery capacity and weight. As long as about one-fifth of lead-acid batteries, the biggest advantage of lithium-ion battery electric bicycles is long life. Disclaimer: The only thing that says that lithium-ion batteries are expensive is to look at the appearance. In fact, the cost is about the same as lead-acid batteries. Now ordinary lithium-ion batteries are guaranteed for 2 years and lead-acid batteries are guaranteed for 1 year. Advantage 2: Lithium-ion batteries have activation-free characteristics. It should be noted that when using lithium-ion batteries, the battery will enter a dormant state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium ion battery is very simple to activate, only need to go through 35 normal charge and discharge cycles to activate the battery and restore normal capacity. Due to the characteristics of the lithium-ion battery itself, it is determined that it has almost no memory effect. Therefore, the user does not need special methods and equipment during the activation process of the new lithium-ion battery. Advantage 3: No memory effect When charging lead-acid batteries and nickel batteries, customers are constantly worried about the memory effect of the batteries. When lithium-ion batteries are used, everyone can take a good word that lithium-ion batteries do not have memory effect.
