Abstract
The invention relates to a system for absorbing electric energy from regenerative braking. The system includes a battery, a thermoelectric module in thermally-conductive contact with the battery, a generator for generating an electric current from regenerative braking, the generator connected to the battery via a first switch and connected to the thermoelectric module via a second switch, and a sensor for measuring a temperature and a charge state of the battery. The system also comprises a controller for activating and deactivating the first switch and the second switch when certain conditions have been met.
