Abstract
Official abstract text for this publication.
A heating system and a method for heating a battery module are provided. The method includes determining if a temperature signal indicates that the temperature level of the battery module is less than a threshold temperature level. If the temperature level is less than a threshold temperature level, and a first battery cell group is not electrically balanced with a second battery cell group, then the method includes selecting at least one of the first and second battery cell groups to be at least partially discharged. If the first battery cell group is selected, then the method includes partially discharging the first battery cell group through a first resistor to generate heat energy.
First claim
Opening claim text (preview).
What is claimed is: 1. A heating system for a battery module, the battery module having first and second battery cell groups, the first battery cell group having at least first and second battery cells electrically coupled in parallel with one another between a first node and a second node, the second battery cell group having at least third and fourth battery cells electrically coupled in parallel with one another between the second node and a third node, comprising: a first volt…
