Problems solved by technology

However, because the backup controller controls the cooling fan motor based only on the Ignition 1 (ING1) signal indicating whether the vehicle's ignition is on, it is inefficient
[0006] Specifically, when controlling the cooling fan motor without considering whether the air conditioner is operated in the vehicle, due to the characteristics of the air conditioner requiring a large amount of power, the heat generation of the high voltage battery is ignored, which may be the cause of shortening the life of the high voltage battery factor

Abstract

The present invention provides a system and method capable of cooling a high-voltage battery by communicating information based on vehicle ignition when an error occurs in Controller Area Network (CAN) communication with a Battery Management System (BMS). Information from the operation of the air conditioner controls the cooling fan motor to maintain the heat generation level of the high voltage battery at an optimum state.

Description

technical field [0001] The present invention relates to a system and method for cooling a high-voltage battery, and more particularly, to a technique capable of effectively cooling a high-voltage battery for an environment-friendly vehicle even when an error occurs in Controller Area Network (CAN) communication, This controller area network communicates the information needed to cool the high voltage battery. Background technique [0002] Such as hybrid electric vehicle (HEV: hybrid electric vehicle), electric vehicle (EV: electric vehicle), plug-in hybrid electric vehicle (PHEV: plug-in hybrid electric vehicle), fuel cell electric vehicle (FCEV: fuel cell electric vehicle) Environmentally friendly vehicles such as , etc. are mounted with an electric motor as a driving power source, and are mounted with a high-voltage battery as a driving power source for the motor. [0003] An environment-friendly vehicle must be installed with a system for cooling the high-voltage battery...
