Battery temperature estimation and management in Lithium Rechargeable Batteries designed through YFJ,include Lithium Rechargeable Batteries with SMBUS
The temperature for High Discharge Battery Pack has a great influence on the battery performance. At present, the surface temperature of the battery can only be measured, while the internal temperature of the battery needs to be estimated by using a heat model. Thermal management of the battery according to the estimated structure.
The 14.8V Battery Packs with LCD Display is in 4S3P ,which has SMBUS data communication and LCD Electricity quantity show
