1. A system for absorbing electric energy from regenerative braking, comprising:

  • 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;

    a sensor for measuring a temperature and a charge state of the battery; and

    a controller for deactivating the first switch and activating the second switch when the charge state is greater than a maximum charge state of the battery, wherein the electric current is transferred to the thermoelectric module and has a polarity that causes the thermoelectric module to cool the battery.
