Systems and methods for determining the target thermal conditioning value to control a rechargeable energy storage system

Abstract

Systems and methods for determining the target thermal conditioning value to control a rechargeable energy storage system. Target thermal conditioning values are determined using a required thermal power value and a heat generation value in order to appropriately condition the RESS for heating and cooling.

Description

[0001] This application claims priority to Provisional Application No. 61 / 407,742, filed October 28, 2010, the contents of which are incorporated herein by reference. [0002] This invention was made with support under Government Contract No. DE-EE0002217 awarded by the Department of Energy. The government has certain rights and interests in this invention. technical field [0003] The present application relates generally to determining a target thermal regulation value for controlling a rechargeable energy storage system (RESS), and more particularly to systems and methods for determining a target thermal regulation value using thermal power and heat generation values. Background technique [0004] Automotive technology is rapidly advancing in the search for alternatives to gasoline as the primary energy source for vehicle propulsion systems. Many of these advances utilize hybrid electromechanical systems that recover some of the mechanical energy of combustion engines as...

Problems solved by technology

[0007] Although temperature can be easily measured, it is difficult to correlate this temperature with the method of driving one or more high voltage devices for RESS heating or cooling

This in turn hampers the efficient operation of the RESS, as well as the ability to operate the RESS in a manner that avoids temperature-related component failures
