The protection board tester is a special equipment used to detect the performance of the battery protection board (the core component of BMS). By simulating abnormal working conditions such as battery charge/discharge, overvoltage/undervoltage, overcurrent/short circuit, etc., it verifies the protection function, parameter accuracy and response speed of the protection board, so as to ensure that it can effectively protect the safety of batteries in practical applications.
◆ The whole machine is modularized, with strong stability and reliability, and convenient maintenance and upgrade;
◆ The main control chip adopts high-performance ARM, and the equipment runs smoothly and stably;
◆ 16-bit ADC with higher voltage and current accuracy than the industry;
◆ Fast test speed: all electronic switches are used, which has obvious advantages over traditional relay mode;
◆ The operation is simple and clear: industrial 7-inch touch control display;
◆ Multi-functional integration: a single device covers overcharge/overdischarge, overcurrent, short circuit, internal resistance, balance, communication and other full-function testing, reducing the cost of equipment input;
◆ Strong compatibility and scalability: support for a variety of battery types (such as ternary lithium, lithium iron phosphate) and protective board models, can be adapted to new standards through software upgrades.
