Control of power flow in battery cells of a vehicle
First Claim
1. A vehicle comprising:
- a GPS;
a battery pack including a plurality of cells;
an electric machine configured to transform electrical power from the battery pack to motive power for the vehicle;
a receiver configured to receive a wireless signal from a key fob; and
at least one controller programmed to inhibit cell balancing for a user-defined time period that is initiated in response to receiving the wireless signal and initiated in response to receiving a location of the vehicle via the GPS.

Abstract
A vehicle includes a high voltage traction battery for providing propulsion energy to the vehicle. A battery control module controls the operation of the battery, and also commands cell balancing out of or between cells of the battery to maintain a relative equilibrium of charge across a plurality of the cells. The battery control module is in communication with an interactive display in the vehicle or a communication device outside of the vehicle. A user can define a time period in which the vehicle is to enter a hibernation mode. During the hibernation mode, the battery control module inhibits cell balancing in the battery. Upon expiration of the user-defined time period, the battery control module enables cell balancing.
