Abstract
A battery pack comprises a plurality of battery modules and a holding spacer which holds the battery module. A plurality of projections are provided on the holding spacer. The projections contact the battery module to hold the battery module and form a flow path for a coolant. A heat generating structure is embedded in the holding spacer or inserted into a hollow section of the holding spacer. In a cold climate, electricity is applied to the heat generating structure, to heat the battery module.
