SYSTEM AND METHOD FOR REBALANCING A BATTERY DURING VEHICLE OPERATION
First Claim
1. A method for rebalancing a battery in a vehicle during vehicle operation, the battery including a plurality of modules, the method comprising:
- determining when an automatic rebalance mode start condition is satisfied;
modifying a target state of charge for the battery at least in part in response to the start condition being satisfied, such that the target state of charge is raised from a standard operating value to a rebalance value;
operating the vehicle with the target state of charge at the rebalance value;
determining when an automatic rebalance mode end condition or an interrupt condition is satisfied; and
modifying the target state of charge in response to the automatic rebalance mode end condition or the interrupt condition being satisfied, such that the target state of charge is lowered from the rebalance value to the standard operating value.

Abstract
A system and method for rebalancing a battery in a vehicle during vehicle operation, the battery including a plurality of modules, is provided. The method may include determining when an automatic rebalance mode start condition is satisfied, modifying a target state of charge for the battery at least in part in response to the start condition being satisfied such that the target state of charge is raised from a standard operating value to a rebalance value, operating the vehicle with the target state of charge at the rebalance value, determining when an automatic rebalance mode end condition or an interrupt condition is satisfied, and modifying the target state of charge in response to the automatic rebalance mode end condition or the interrupt condition being satisfied such that the target state of charge is lowered from the rebalance value to the standard operating value.

20. A system for rebalancing a battery in a vehicle during vehicle operation, the system comprising:
-
a battery having a plurality of modules, wherein each of the modules includes one or more cells; and
a controller in electronic communication with the battery for determining when an automatic rebalance mode start condition is satisfied, modifying a target state of charge for the battery at least in part in response to the start condition being satisfied such that the target state of charge is raised from a standard operating value to a rebalance value, determining when an automatic rebalance mode end condition or an interrupt condition is satisfied, and modifying the target state of charge in response to the end condition or the interrupt condition being satisfied such that the target state of charge is lowered from the rebalance value to the standard operating value. - View Dependent Claims (21, 22)
