US 12,113,182 B2 · Battery cooling system and method for generating thermal model thereof

Abstract

A battery cooling system includes: a heating element for performing a resistance function of a battery to be subjected to a cooling test; a heating-load controller for controlling a heating load of the heating element according to a thermal model; an environment controller for controlling at least one battery cooling environment parameter such as outdoor temperature and initial temperature; a power supply for applying a current for each evaluation condition by connecting a charger/discharger to the heating element; a cooling processing part for supplying a cooling fluid such as air, coolant, or a refrigerant at a constant temperature and flow rate; and a cooling performance determination part for measuring a temperature of a battery cell over time and determining whether a target performance of the battery is satisfied.

A battery cooling system comprising:

a heating element configured to perform a resistance function of a battery to be subjected to a cooling test;
a heating-load controller configured to control a heating load of the heating element according to a thermal model;
an environment controller configured to control at least one battery cooling environment parameter including an outdoor temperature and an initial temperature;
a power supply configured to apply a current for each evaluation condition by connecting a charger/discharger to the heating element;
a cooling processing part configured to supply a cooling fluid at a constant temperature and flow rate;
and
a cooling performance determination part configured to measure a temperature of a battery cell over time and to determine whether a target performance of the battery is satisfied,
wherein the heating element is a battery substitute that does not cause a thermal runaway phenomenon when being subjected to the cooling test by replacing the battery under a high-load condition.
