A new energy vehicle motor battery high and low temperature cycle test system

Abstract

The invention provides a new energy vehicle motor battery high and low temperature cycle test system, including a cycle test pipeline circuit and a control unit; a liquid storage tank provides circulating fluid, and the circulating fluid flow is output through a circulating pump, and the control unit controls the first three-way shunt The three-way opening and closing degree of the valve determines whether the circulating fluid flows to the heating branch or the cooling branch; according to the circulating fluid flow direction, the control unit controls the three-way confluence valve to make the circulating fluid flow back to the main circuit and connect with the liquid inlet of the equipment under test; The liquid flows back from the liquid outlet of the equipment under test to the liquid storage tank to complete the entire system circulation loop; the liquid inlet and outlet of the equipment under test are equipped with various sensors and valves. The invention can respectively carry out high and low temperature cycle tests on the battery and the motor of the new energy vehicle, and is suitable for testing equipment with high requirements on temperature changes.

Description

technical field [0001] The invention belongs to the technical field of testing instruments, and in particular relates to a high-low temperature cycle testing system for a motor battery of a new energy vehicle. Background technique [0002] The high and low temperature test system is mainly aimed at the adaptability test of electrical and electronic products, their original devices, and other materials when they are stored, transported, and used in high-temperature and low-temperature environments. According to national standard requirements or user-defined requirements, under low temperature and high temperature conditions, conduct environmental simulation tests on the physical and other related characteristics of electronic technology products. After the test, pass the test to judge whether the performance of the product can still meet the predetermined requirements , in order to be used for product design, improvement, identification and factory inspection. At present, th...
