Small size, weight is only 47% of lead-acid battery; sustainable discharge in minus 41 degree environment, discharge rate exceeds 75%... New lithium iron phosphate lithium-ion starter battery independently developed by Beijing Henglvyuan Technology Co., Ltd., a few days ago Passed the identification. Academician Yang Yusheng of the Chinese Academy of Engineering and Wu Feng, a professor at the Beijing Institute of Technology, and other experts believe that the technology has reached the leading level in China.
Beijing Henglvyuan and researchers said that the new lithium iron phosphate lithium-ion starter battery has two major technological innovations. The first is to solve the problem of low temperature performance of lithium iron phosphate batteries. In the minus 41 degree environment, sustainable discharge, discharge rate of more than 75%, outstanding low temperature performance; second is the development of a starter battery management and protection system, so that the battery under a very cold temperature withstand 1000 operating current management protection system, to achieve The battery is reliable and stable under a variety of harsh conditions, and it can be blindly exchanged with the currently used lead-acid starter battery, without any changes or changes.
"The product has achieved the first time at minus 41 degrees Celsius in the low-temperature conditions in the country. It is close to the end-of-life vehicle equipped with a lithium-ion starter battery and parked in the freezer for 24 hours. Without any auxiliary facilities, the ignition was started successfully," said the researcher.
Wu Feng and other experts said that compared with the current domestic starter batteries, Evergreen and lithium iron phosphate lithium-ion starter batteries have obvious advantages, in addition to small size, light weight, but also maintenance-free, monthly self-discharge rate of less than 3%, safe and reliable ,energy saving.
