A method is provided for controlling the temperature of a traction battery in a hybrid vehicle, where the hybrid vehicle includes an internal combustion engine and an electric motor for traction power. The method includes providing a first temperature regulating circuit for the internal combustion engine, providing a second temperature regulating circuit for the traction battery, heating the traction battery by an electrical heater provided in the second temperature regulating circuit in series with a pump, a radiator and the traction battery, transferring power to the electrical heater via a DC/DC converter from the electrical motor, which electrical motor is driven by the internal combustion engine, while the battery is below a predetermined temperature interval.
