Problems solved by technology
[0004] At present, when the battery system is assembled and tested offline, the battery system is mainly charged and discharged through the charge and discharge test cabinet. However, the existing charge and discharge test cabinets generally only have 2 channels, and can only test 2 battery systems at the same time. To realize more battery system tests, it is necessary to increase the configuration of test equipment. For example, 30 battery systems need to be tested at the same time. 15 sets of test equipment and multiple testers are required, which cannot be operated by a single person, which greatly increases the cost of testing

Description
technical field [0001] The invention relates to the technical field of battery system off-line function testing, in particular to a multi-channel battery charging and discharging testing system. Background technique [0002] At present, due to the long life of lithium batteries, light weight, small size, and no memory effect when charging and discharging, and with the guidance and support of national policies, lithium batteries are more and more used in two-wheel and tricycle vehicles. Because of the protection board, the safety and quality reliability of the battery system must be improved. [0003] After the battery system is assembled, it must be tested off-line to check whether the relevant functions of the battery system meet the design requirements, so as to detect possible problems in the battery system in time and avoid safety accidents during operation. [0004] At present, when the battery system is assembled and tested offline, the battery system is mainly charge...
