Battery Management System(BMS)

Voltage Protection

• Discharging Low Voltage Protection:
  When any battery cell voltage is lower than the protection value during discharging.The over-discharging protection starts, and the battery buzzer makes an alarm sound. Then battery system stops supplying power to the outside, When the voltage of each cell recovers to rated return range, the protection is over.

• Charging Over Voltage Protection:
  When total voltage or any battery cell voltage reaches the protection value during charging,battery stops charging. when total voltage or a cell recover to rated return range, the protection is over.

Current Protection

• Over Current Protection in Charging:
  When the charging current is greater than the protection value, the battery buzzer alarms and the system stops charging. Protection is removed after rated time delaying.

• Over Current Protection in Discharging:
  When the discharge current is greater than the protection value, the battery buzzer alarms and the system stops discharging. Protection is released after rated time delaying.

Note
The buzzer sound alarm setting can be manually turned off on the background software, and the factory default is on.

Current Protection

• Less/Over temperature protection in charging:
  When battery’s temperature is beyond range of 0℃~+65℃ during charging, temperature protection starts, device stops charging.
  The protection is over when it recovers to rated return range.

• Less/Over temperature protection in discharging:
  When battery’s temperature is beyond range of -20℃*+65℃ during discharging, temperature protection starts, device stops supplying power to the outside.

Other Protection

• Short Circuit Protection:
  When the battery is activated from the shutdown state, if a short circuit occurs, the system starts short-circuit protection for 30 seconds.

• Self-Shutdown:
  When device connects no external loads and power supply and no external communication for over 72 hours, device will dormant standby automatically.

Caution
Battery’s maximum discharging current should be more than load’s maximum working current.

Technical preparation

Electrical interface check
Devices that can be connected directly to the battery can be user equipment, power supplies,or other power supplies.

• Confirm whether the user’s PV power generation equipment, power supply or other power supply equipment has a DC output interface, and measure whether the DC power output voltage meets the voltage range requirements in Table 2-2.
• Confirm that the maximum discharge current capability of the DC power interface of the user’s photovoltaic power generation equipment, power supply or other power supply equipment should be less than the maximum charging current of the products used in Table 2-2. If the maximum discharge capacity of the DC power interface of the user’s photovoltaic power generation equipment is greater than the maximum charging current of the products used in Table 2-2, the DC power interface of the user’s photovoltaic power generation equipment shall have a current limiting function to ensure the normal operation of the user’s equipment.
• Verify that the maximum operating current of the battery-powered user equipment(inverter DC input) should be less than the maximum discharge current of the products used in Table 2-2.

The security check

• Firefighting equipment should be provided near the equipment, such as portable dry powder fire extinguisher.
