It is a kind of charge-discharge cycles test system integrating the charge-discharge cycles tests, battery pack functional tests and charge-discharge data monitoring. This test system is mainly applied to the high-power battery packs, such as the battery packs of EV, electric bicycles, power tools, gardening tools and energy storage equipment etc. The system can offer excellent accuracy and flexibility and all the discharged energy can return to the power grid.
The test system is configured with graded protection mechanism, including AC side hardware level protection, like grid over/under-voltage protection, anti-surge protection, anti-islanding protection, over/under frequency protection, phase loss protection, AC short-circuit protection, lightning protection, hardware over-temperature protection, self-check protection and emergency stop protection; DC side hardware level protection, like bus-bar over/under-voltage protection, hardware over-temperature protection, voltage reverse protection, power reverse protection, self-check protection and loose cable protection; integrated battery-side protection, like battery total voltage upper/ lower limit protection, cell voltage upper/ lower limit protection, battery temperature upper limit protection, battery current upper limit protection, battery capacity upper/ lower limit protection, voltage difference protection, battery BMS drop protection, CAN communication drop protection, voltage fluctuation exception protection, current fluctuation exception protection and temperature fluctuation exception protection; and peripheral equipment linkage protection, like temperature chamber fault linkage protection, water-cooler fault linkage protection, peripheral IO signal linkage protection, auxiliary cell voltage sampling linkage protection (independent redundancy protection), and peripheral communication disconnection linkage protection; software protection (Data security), like resumption of power outage data, offline test function on the host computer, channel data migration and data backup protection. In addition, the system also supports test step calibration, DBC file import, such as file editing, saving and import, serial port protocol self-editing, basic setting for global parameters, advanced setting for global parameters, SOC real-time calculation and current grading, which can be activated for parallel models.|
