Abstract
A regenerative elevator system operates in three modes: motoring, idle and regeneration. During the regeneration mode, the elevator motor operates as a generator, and electrical energy is stored in an energy storage system for later use. The energy storage system may be located in a machine room or hoistway where temperature can vary widely. A thermoelectric thermal management system provides thermoelectric cooling or heating to maintain the energy storage system within a desired operating temperature range.
