AUTOMOTIVE BATTERY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18454075 titled 'AUTOMOTIVE BATTERY SYSTEM
Simplified Explanation
- Battery output power is limited when temperature is high to prevent further temperature rise. - Output power limitation occurs when ambient temperature is at or above a certain level, vehicle load is at or above a certain level, and battery cooling device is operating at or above a certain level. - Output power limitation is set to a high-load value lower than the normal condition when temperature is at or above a specific lower limit temperature.
Potential Applications
This technology can be applied in electric vehicles, portable electronic devices, and renewable energy storage systems.
Problems Solved
- Prevents overheating of batteries - Ensures safe operation of battery systems - Extends battery lifespan
Benefits
- Improved safety - Enhanced battery performance - Longer battery life span
Original Abstract Submitted
When the temperature of a battery is high, the output power of the battery is limited to suppress the temperature rise. Upon fulfillment of three conditions of (i) the ambient temperature is equal to or higher than a predetermined temperature, (ii) the vehicle traveling load is equal to or greater than a predetermined traveling load, and (iii) the operating load of a battery cooling device is equal to or greater than a predetermined operating load, the output power of the battery is limited using a high-load output limiting value less than an output limiting value for the normal condition in a temperature range equal to or higher than a second power restrictive lower limit temperature that is equal to or lower than a first power restrictive lower limit temperature for the normal condition.
