Fast Charge Test Method for Battery Pack Systems with Thermal Management

Abstract

This paper introduces a kind of substitute bench testing method for vehicle application development and testing method of the test requirements, including battery fast conversion cycle test equipment, enter type incubator, liquid-cooled machine and ancillary equipment composed of a set of test system, through the walk-in constant temperature box to simulate the new energy vehicles under different environmental conditions of the test requirements, Liquid-cooled machine and auxiliary parts to complete the battery thermal management system need cooling fluid conditions, the battery conversion cycle test equipment to simulate the dc fast charging way of filling pile, complete battery thermal management system test, shorten the filling fast charging time and improve battery fast charge security, for troubleshooting and data collection and analysis, Improve work efficiency, save costs, and eliminate customer anxiety about battery life and charging time.
