Abstract: 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.

Abstract: A method is provided for controlling operation of a hybrid automotive vehicle, equipped with an internal combustion engine, at least one electric machine connected to a traction battery set and at least one logical control unit. Each of the internal combustion engine and the electric machine is adapted to deliver torque to a driveline of the vehicle and the method includes a) watch of an activity area of the vehicle and/or watch of an electrical/electronic network of the vehicle in order to detect a user in the activity area and/or the use of an auxiliary equipment of the vehicle; b) determination of whether or not the watch of step a) has detected, during a given period of time, a user in the activity area and/or the use of an auxiliary equipment of the vehicle; c) if the result of the determination of step b) is negative, initiate a shutdown procedure of at least the traction battery set.
