Which kinds of lithium-ion battery electric vehicles are not good

1. The high price of lithium-ion battery electric vehicles is due to the high cost of lithium-ion batteries. Nowadays, good domestic lithium-ion batteries are mostly used for electric cars. When used in electric vehicles, the cost will appear to be too high. Because the material has been destined, it will generally be 40~70% higher than lead acid. 2. The electric core is mixed with technology, which leads to continuous dangerous situations. Good batteries are very expensive, 6~9 yuan/piece. Some manufacturers, in order to make profits, use domestic brand-name batteries or imported disassembled batteries, and their life cannot be guaranteed. At the same time, poor production and assembly processes or no protection board is added, leading to failures in use and serious explosions. Many battery packs were made without external protection, which caused the battery to break down and short-circuit in the event of a collision, causing fire. 3. In order to reduce costs, some unscrupulous manufacturers steal capacity. Some businesses, for profit, will use 15AH lithium-ion batteries to sell 20AH lithium-ion batteries. Stealing capacity has also become the biggest income point for many peers to seek profit. Because of electric vehicles, 1A is the voltage of 16 batteries in series. 4. Deliberately lower the voltage to give customers the higher the voltage, the more batteries they use, and the greater the power. But some colleagues, for the benefit of the same AH, use 48V batteries instead of 60V batteries, the capacity is the same, but a total of 1A4 batteries are missing. Thereby reducing the power. 5. If the lithium-ion battery is below 0, there will be a problem of capacity reduction. Lithium-ion battery characteristics, below 0, there will be capacity reduction, temperature recovery, and energy recovery. Therefore, the southern one is more suitable.
