S12-290AGM-RE加拿大ROLLS蓄电池12V260AH新能源工业电源
磷酸铁锂电池组安装前必须测量开路电压，开路电压差不能大于50mV，需做好电池测试并记录。用假负载可以对电池组按0.1C10和0.2C5进行容量试验，此试验不需接入电池管理系统（BatteryManagementSystem，BMS），只需将电池组串联起来，放电过程中必须严格检测电池单体电压，每小时对电池的总电压、放电电流、电池单体电压进行测量并记录。电池在放电后期每10min检测放电电池单体电压低的电池，若有一只电池端电压到2.5V马上停止放电，计算出实际电池放出的容量与蓄电池额定容量是否一致，若基本一致则证明电池放电试验合格，再对电池进行充电。 
Before installing the lithium iron phosphate battery pack, theopen circuit voltage must be measured, and the open circuit voltagedifference cannot exceed 50 mV. The battery test must be done welland recorded. A false load can be used to conduct capacity tests onbattery packs at 0.1C10 and 0.2C5. This test does not require theconnection to a Battery Management System (BMS), only the batterypacks need to be connected in series. However, during the dischargeprocess, the voltage of each battery cell must be strictly checked,and the total voltage, discharge current, and voltage of thebattery cell must be measured and recorded every hour. In the laterstage of discharge, the battery should be tested every 10 minutesfor batteries with low individual voltage. If the terminal voltageof one battery reaches 2.5 V, it should stop dischargingimmediately. Calculate whether the actual discharged capacity ofthe battery is consistent with the rated capacity of the battery.If it is basically consistent, it indicates that the batterydischarge test is qualified, and then charge the battery.
