BATTERY MANAGEMENT SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240097232 titled 'BATTERY MANAGEMENT SYSTEM

Simplified Explanation

The battery management system described in the patent application includes multiple battery units connected in parallel, with a control device that regulates the temperature of each battery unit. Specifically, the system consists of a first battery unit with a LFP cell and a second battery unit with a ternary battery. The control device adjusts the temperature so that the LFP cell is kept at a higher temperature than the ternary cell when the overall system temperature is at or below a reference temperature.

• Explanation of the patent/innovation:

 * The system manages the temperature of different types of battery cells within a battery management system.
 * It ensures that the LFP cell is maintained at a higher temperature than the ternary cell under specific temperature conditions.
 * The control device executes temperature control to optimize the performance and longevity of the battery units.
