2.3 Battery Management System (BMS)
2.3.1 Voltage Protection
Low Voltage Protection during Discharging Process：
When the voltage of a battery cell or the total voltage is lower than the protection value, the battery
will start over-discharging protection during the discharging process and the battery ALM indicator
will be always on. Then the battery system will stop supplying power to the loads. The protection
will end when the voltage is restored to the rated return range.
Over Voltage Protection during Charging Process：
When the total voltage or a battery cell voltage reaches the protection value during the charging
process, the battery ALM indicator will be always on, and the battery will stop charging. The
protection will end when either the total voltage or the voltage of any battery cell is restored to the
rated return voltage range.
2.3.2 Current Protection
Over Current Protection during Charging Process：
When the battery pack is not equipped with a charging current limiting module or the charging
current limiting function is disabled, the BMS should have a charging over-current protection
function. Try the protection and recovery every 5 minutes. If the charging is still over-current, it will
be protected again. If the charging is not over-current, it should be automatically protected and
recovered.
Over Current Protection during Discharging Process：
When the discharge current is greater than the protection value, the system will stop supplying
power to the loads, and disable the output. The BMS detects whether there’s discharging over-
current every 1 minute. If there is no discharging over-current, it will be restored to the standby
state. If there is discharging over-current, it will continue the protection. Also, it can resume normal
operation by charging.
2.3.3 Temperature Protection
Less/Over Temperature Protection during Charging Process：
When battery’s temperature is beyond range of 0 ℃~+55 ℃during charging, the temperature
protection will start, and the device will stop the charging process.
Less/Over Temperature Protection during Discharging Process：
When battery’s temperature is beyond range of -20℃~+55℃during discharging, the
temperature protection will start, and the battery will stop its output.
2.3.4 Other Protection
Short Circuit Protection：
If the battery is activated in the off state, the short-circuit protection will be triggered. Detect if there
is an external short-circuit every 5 seconds and turn on the pre-charging. If there is no short-circuit,
it will be restored to the standby state. If there is still a short-circuit, the protection will be continued.
After 5 consecutive short-circuit detections, the detection will be ended and the normal output
function is no longer automatically restarted. It can only be restored by manual reset or charging
after the fault is eliminated.
Sleep mode:
When the battery does not supply power to the load or connect to any power source, and there is
no external communication for more than 48 hours, the battery will automatically enter the standby
sleep mode.

3.1.3 Technical preparation
Electrical interface check
Devices that can be connected directly to the battery can be user’s equipment, power supplies,
or other power sources.
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
PV power generation equipment, power supply or other power supply equipment is greater 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 PV power generation
equipment is less than the maximum charging current of the products used in Table 2-2, the DC
power interface of the user's PV 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) is 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.
Automatic fire fighting system shall be provided for the case where necessary.
No flammable, explosive and other dangerous articles are placed beside the battery.
