Abstract

An apparatus is described including a hybrid power train having an internal combustion engine and an electric motor. The apparatus includes a hybrid power system battery pack that is electrically coupled to the electric motor. The apparatus includes an energy securing device that is thermally coupled to the hybrid power system battery pack. The energy securing device selectively removes thermal energy from the hybrid power system battery pack, and secure removed thermal energy. The energy securing device secures the removed thermal energy by storing the energy in a non-thermal for, or by using the energy to accommodate a present energy requirement.

Description

technical field [0001] This application relates to thermal management of battery packs, and more particularly, but not exclusively, to battery packs in hybrid powertrain systems. Background technique [0002] Battery packs used in hybrid applications will lose efficiency and operating life if the temperature of the battery pack is too high or too low. During the early operating hours of the system, the temperature of the battery pack is often low. After applying warm-up and especially under high power conditions, the battery pack can generate excessive heat. Therefore, there is a need for further improvements in this technical field. Contents of the invention [0003] According to an aspect of the present invention, there is provided a device for thermal management of a battery pack, comprising: a hybrid power train including an internal combustion engine and an electric motor; a hybrid power system battery pack, the hybrid power system battery pack electrically coupled...
