Wanxiang one two three 53Ah VDA batteries are connected to the international standard by acupuncture test

Recently, Wanxiang one, two and three heavy-duty products, 53AhVDA battery products, have successfully designed and finalized. The product has the following characteristics: high energy density - product energy density reaches nearly 260Wh / kg; high power - as an energy-type battery product, normal temperature power 10s output power density reached 1500W / kg; long cycle life - The high temperature life expectancy will reach 1500 times or more; high safety - successfully passed the tests required by GBT-31485-2015, especially through the USABC (American Advanced Battery Alliance) EUCAR2 acupuncture test, achieving a major safety breakthrough: no Leakage, no smoke, no fire, no explosion. Nowadays, the pure electric vehicle market is driven by policies, and the battery energy is increasing. Under the same test conditions, the degree of damage caused by battery failure is also rising. For example, the difficulty level of acupuncture may rise directly from EUCAR2 or EUCAR3 to EUCAR5.

Although major battery companies have some ways to improve acupuncture in technology, often these improvements cannot fully balance battery performance. Therefore, for most manufacturers, acupuncture is an insurmountable obstacle.

In China, there is no mandatory requirement for acupuncture testing, but European and American OEMs, General Motors, etc. still adhere to European and American safety standards in global projects. Acupuncture is still in its mandatory testing programs, such as General Motors and Volkswagen currently implement the USABC acupuncture methods and standards. This means that if Chinese battery companies want to keep up with the pace of globalization, they must still strictly demand themselves and pass the acupuncture test. This is also a requirement for battery safety. As a world-renowned manufacturer of power battery manufacturers for electric vehicles, Wanxiang One Two Three has been adhering to the product development concept of “safety is more important than everything”, maintaining strict product development standards, and product technical review strictly follows that acupuncture must meet The harsh conditions of USABC, in line with international standards, have achieved a major breakthrough in battery safety.
