Problems solved by technology

However, the lead-acid battery is not perfect. It has low specific energy density, difficult to start at minus 20 degrees, and heavy weight. It requires the battery to release a large current of 300-800A at the moment of ignition and start-up, which is equivalent to 3-8C or more of the battery. deep discharge, resulting in shortened or terminated battery life
The service life of batteries sold in the existing market ranges from 1 to 2 years, among which the service life of taxis and urban buses is less than one year due to frequent start and stop
[0005] Lithium-ion batteries have the advantages of high specific energy, long cycle life, green environmental protection, light weight and small size, and are the power source of new energy pure electric vehicles (EV) and hybrid electric vehicles (HEV). There are still problems to be solved in terms of high price, battery consistency and safety
