Battery safety is the core of electric vehicle safety. Mazlin said that safety has always been the top priority of Weihong Power. Weihong Power is committed to the research and development of high-safety batteries, and solves the problem of battery safety through research on non-flammable electrolyte technology. In terms of safety, in addition to the safety design of the battery cell, the system also realizes double protection through built-in silicone oil and external MSD. In addition, Weihong Power continues to increase the energy density of batteries on the basis of fast charging, long life and high safety. According to Mazlin, Weihong Power currently has a fast-charging battery energy density of up to 230Wh/kg.

　　While carrying out battery cell research, Weihong Power has also done a lot of research on PACK. According to Mazlin, the new generation of standard commercial vehicle cabinets launched by the company this year is 30% lighter than before. The energy density of the system battery pack is above 135Wh/kg.

　　Battery China.com learned that Weihong Power has released four generations of fast-charge batteries in succession since it launched the first generation of fast-charge batteries in 2009-GenI. The new high-energy-density fast-charge battery launched by Weihong Power in 2018 has an energy density of 220Wh/kg and can be fully charged in 20 minutes. At the same time, the ultra-long cycle life can also guarantee the application of the full life cycle of eight years. According to Mazlin, Weihong Power invested in Chongqing’s first fast charging line in 2011. As of March 2018, there were 21,000 sets of battery systems in the world, charging between 2C and 5C, and the accumulated operating mileage exceeded 1.9 billion kilometers, the products are distributed in more than 150 cities in 13 countries and regions around the world, and there has never been a safety accident caused by the battery itself.
