Optimization-based predictive method for battery charging

摘要

A battery management system for a rechargeable battery includes a battery monitor configured to acquire data regarding the rechargeable battery and a processor. The processor is configured to determine an initial state of charge of the battery based on the acquired data; determine a target state of charge for the battery; determine a plurality of charging solutions to achieve the target state of charge based on an optimization of one variable of the battery of a plurality of variables of the battery; narrow the plurality of charging solutions to charging solutions that meet an objective of each of the remaining plurality of variables of the battery; select the charging solution that corresponds with the fastest charge time for the battery from the charging solutions that meet the objective of each of the plurality of battery variables; and command a controller to regulate an amount of charge to the battery in accord with the selected charging solution.
