Patent Images
1. A method for optimizing the charging cycle of a battery pack of an electric vehicle, the method comprising the steps of:
- monitoring at least one operating condition of said battery pack;
determining a set of charging requirements of said battery pack;
monitoring at least one performance parameter corresponding to an electric vehicle auxiliary system;
determining a set of power requirements of said electric vehicle auxiliary system;
determining a maximum available power obtainable from an external power source coupled to said electric vehicle;
weighing said set of charging requirements against said set of power requirements of said electric vehicle auxiliary system to determine an optimal power split; and
distributing said maximum available power to a charging system coupled to said battery pack and to said electric vehicle auxiliary system in accordance with said optimal power split.

Abstract
A system for optimizing battery pack charging is provided. In this system, during charging the coupling of auxiliary systems (e.g., battery cooling systems) to the external power source are delayed so that the battery pack charge rate may be optimized, limited only by the available power. Once surplus power is available, for example as the requirements of the charging system decrease, the auxiliary system or systems may be coupled to the external power source without degrading the performance of the charging system.
