Abstract

The invention discloses a device for heating a battery box by waste heat of heat generating equipment in an electric automobile. The device comprises a battery box temperature sensor, a heating equipment temperature sensor, an electromagnetic valve A, an electromagnetic valve B and an electric heater which are controlled by a finished automobile controller; a circulating pipeline A is used for sequentially connecting a water pump A and a plurality of heating equipment in the automobile in series, and the electromagnetic valve A is arranged on the section, at an inlet of a medium passageway A, of the circulating pipeline A; a circulating pipeline B is used for sequentially connecting a water pump B, the battery box, a water tank B and an electric heater in series; the circulating pipeline A also comprises a parallel bypass which is connected with the circulating pipeline A through a tee joint A and a tee joint B; and a circulating pipeline C is from the outlet end of the water pump A and sequentially passes through the heating equipment, a heat radiator and the water tank A to reach the inlet end of the water pump A, and the electromagnetic valve B is arranged on the section, between the heat radiator and the tee joint B, on the bypass. The device disclosed by the invention can be used for heating the battery box by effectively utilizing the waste heat generated in the electric automobile, thereby reducing the loss of electric energy and improving the utilization efficiency of energy.

Description

technical field [0001] The invention relates to a heat preservation device for a battery box of an electric vehicle, in particular to a device for heating a power battery box by using waste heat. Background technique [0002] Because the power battery used in electric vehicles has strict temperature requirements, when the ambient temperature is relatively low, in order to ensure that the temperature of the battery box meets the requirements of the battery, it needs to consume a certain amount of electric energy to convert it into heat to heat the battery box. At the same time, in order to ensure the normal operation of motors, motor controllers, DCDC, chargers and other electrical equipment, it is necessary to take necessary heat dissipation measures for these equipment to improve the efficiency of the equipment and the safety of the vehicle. In the above two processes, part of the electric energy is consumed to dissipate heat for the motor and other equipment and to heat th...
