AI Technical Summary
The performance optimization of lithium iron phosphate batteries in low-temperature environments lacks scenario adaptability, and the performance evaluation and repair management are disconnected, resulting in poor operational stability and low performance recovery efficiency.
By acquiring information on the low-temperature application scenarios of the target lithium iron phosphate battery, dynamic optimization of the battery is performed, and a battery structure optimization parameter system is constructed. Low-temperature twin simulation is performed using the battery historical low-temperature operation dataset collected by the BMS to generate a battery low-temperature operation twin. Low-temperature performance evaluation indicators of the battery are constructed, predictive performance parameters of low-temperature operation of the battery are generated, and repair strategy analysis is performed to construct a battery low-temperature performance repair strategy scheme library to realize battery operation control.
It enables precise intervention throughout the entire process of low-temperature performance of lithium iron phosphate batteries, improving the battery's operational stability and performance recovery efficiency in low-temperature scenarios.
