Energy-saving type battery charge and discharge test equipment and test method

Abstract

The invention discloses an energy-saving type battery charge and discharge test equipment and test method. The test equipment comprises a test channel, used for connecting two battery packs, and for collecting data and controlling the exchange of electric quantities of two battery packs; a data processing center used for receiving data transmitted by the test channel for performing treatment and flow control; a data extractor used for performing test data extraction and screening on the data acquired by the data processing center; and a data storage used for storing the data acquired by the data processing center. According to the equipment and method provided by the invention, the charge and discharge processes are adjusted according to the charge and discharge states of the batteries inbattery charge and discharge tests, the own electric quantities of the batteries are used to perform the charge and discharge tests, so that no or less electricity is acquired from the power grid to achieve the test purpose.

Description

technical field [0001] The invention belongs to the technical field of battery charging and discharging testing, in particular to an energy-saving battery charging and discharging testing equipment and a testing method. Background technique [0002] With the rapid development of the electric vehicle industry, the demand for power battery production capacity is increasing. At present, my country's planned power battery production capacity has reached more than 200GWh, and there are more and more new battery factories and pack factories. The most energy-consuming part of the battery and pack production process is the battery or module charge and discharge test process. This is mainly because the initial test equipment takes power from the grid when charging the battery, but discharges it directly to the resistor, in the form of heat release, resulting in a great waste of electric energy and a rise in the temperature of the test environment. [0003] Most of the existing charg...

The most energy-consuming part of the battery and pack production process is the battery or module charge and discharge test process. This is mainly because the initial test equipment takes power from the grid when charging the battery, but discharges it directly to the resistor, in the form of heat release, resulting in a great waste of electric energy and a rise in the temperature of the test environment

[0003] Most of the existing charging and discharging equipment is feedback type. Generally, when the battery discharges, it directly feeds back to the grid and is used by other loads in the factory area. Although it can save part of the electricity bill, if the load in the factory area is not enough, the discharged power may be directly fed back to the large battery through the master meter. Power grid, resulting in poor stability of the large power grid, and factories may face huge fines
