Method for determining target temperature of lithium ion battery used in electric car, involves determining target temperature of battery based on battery charge state and current flow rate of battery

摘要

The method involves determining a current battery state and determining a previous charge throughput of the battery. The target temperature of the battery is determined based on battery charge state and current flow rate of the battery. The reference value of the variation rate of maintenance state with the load throughput is determined as quotient of difference between the previous load throughput of the battery and the predetermined total charge throughput of the battery. An independent claim is included for battery management unit.
