Technical bottleneck of simple analysis of power lithium battery pack

The key factors for Chinese electric cars to have a bad start are the cruising journey, charging speed and safety, all of which are caused by the poor technology of power lithium battery, so they can be regarded as the three technical bottlenecks of power lithium battery pack. Below by the name of the technology to the technical staff to introduce you

I. short range: with the continuous improvement of technology, the range of electric vehicles powered by lithium battery has increased from less than 100 km at the beginning to about 300 km at the time of main stream, and the range of a single model has exceeded 400 km. But that is still a long way from the 500km that gas-powered cars must have travelled. This problem can be solved by a series of single cell, but the negative problem is that the volume is too large, increase the vehicle trek is not convenient.

Slow charging speed: compared with the short journey, slow charging of lithium battery pack is a bigger constraint for electric cars. At normal speeds, the electric car's lithium battery is fully charged for four to eight hours. Now also have agile rechargeable lithium battery, can be filled in 1 ~ 2 hours, but its negative impact is great, the life will be reduced to the original 1/3, and the battery function will significantly decline. Fuel cars do not have these questions, refueling time does not exceed 5 minutes, safety and stability can be guaranteed.

Iii. Safety function to be improved: since the birth of lithium battery pack, safety questions have always puzzled consumers. From mobile phones and laptops to today's electric cars, safety accidents keep happening. With the exception of Nissan and Tesla, where there have been no reports of fires, China's Chung Thai and BYD, America's General Motors and Fiske's electric vehicles have all had their own fires or fires.

Above is the standard of science and technology of the technical personnel to introduce the power lithium battery technology is bottleneck which, as a high quality lithium battery equipment manufacturers, to tell you the existence of the above three questions, The cost of developing lithium batteries has increased due to overcoming these three shortcomings., high-value goods as restricted the power battery and power battery electric vehicle.
