Chargery BMS for 12 or 24 Volt Lithium Battery Packs

Features:

• Advanced ADC measurement technology, high accuracy, high voltage, and high current detection circuit. The maximum voltage measurements tolerance is within 5mV at up to 68V.
• Supports regenerative braking, during braking operation can charge the battery pack and the discharge power (Wh) will decrease to respond to the braking power.
• Charge/discharge current up to 600A. Bigger current can be customized.
• 1.2A per cell balance current is very useful for a large capacity battery pack, the feature can resume all cell voltage balancing in the shortest time. Over temperature protection to make sure the system is safe during balancing.
• Calculates and displays the charge and discharge power (Wh), generally the battery rated power is the rated voltage multiplied by the rated battery capacity.
• The TFT LCD screen provides rich information including current, voltage, power, capacity, battery status, SOC, and temperature etc.
• Maximal safety protection within the range parameters can be setup. The BMS will alarm and cutoff charge or discharge according to the users’ setup, out of range parameters, and trigged absolute maximum ratings. It will force a cutoff charge or discharge to protect the battery from fire.
• Minimizes the power consumption by drawing current from all cells or an external power supply.
• Dual power design, the unit can be powered by all cells or an external power supply.
• Detects the cell count at any time and compares with the count detected when the switch was on the first time. If it is not uniform, the device will alarm and cutoff the charge or discharge according to the users’ setup. The feature can prevent any cell connection from becoming loose.
• Sound alarm and LED alarm will be triggered when any warning events happen, and then wait several seconds before cutting off or not cutting off the charge or discharge. The delay time can be programmed.
• Charge relay and discharge relay are controlled independently.
• Two temperature sensors monitor battery temperature on different positions.
• Supports upgrading the firmware program by USB port.
• Provides users the maximal flexibility, key parameters can be programmed.
• Displays the battery SOC or called battery gauge similar with car dashboard. Cell count, battery pack voltage and battery gauge (%) is displayed simultaneously.
• In case that the battery pack need not be charged and discharged, Press STOP button to enter sleep mode to save energy consumption. At this mode, Charge and Discharge is forbidden, and LCD back light is off. Press any key to resume normal work mode.
• LCD back light ON time can be programmed to save energy. When it is OFF, press any key to resume “ON”.
• Cell count error protection
• Over charge protection
• Under voltage protection
• Over current protection when charged or discharged
• Over temperature protection
• Over differential cell voltage protection
• Over differential battery temperature protection
• Under SOC protection
