The APL-LFP LiFePO4 battery system installation, operation, maintenance should follow
important
recommendations in this manual:
 The equipment shall be installed by the professional training staff
 Battery maintenance should be carried out by the experienced professionals and aware
of the preventive measures on the potential harm of the battery.
 Note: Be care of the risk of electric shock for large current in case of battery short
circuit, pay attention to the following points during operation
 Remove watches, rings or other metal objects
 Use tools with insulated handles
 Do not place tools or metal objects on the battery
 Do not direct access to the battery system to the mains grid power outlet
 Do not put the battery system into fire, do not use or storage the battery near to the
high temperature source
 Do not use liquid or other objects placed into the battery system.
 Do not open or cut the battery, not to hit, throw or step on the battery
 Using special communication between battery module and power plant to charge
battery
 Be sure to subject to charge and discharge parameters setting in this manual
 The output interface of the system is still voltage when grid power cut, avoid electric
shock or short circuit when operation
 Please check if the box is damaged. If damaged, please immediately notify the supplier
 If you find leaking liquid or white powder residue on product, prohibit operation.

Part 2 –Product Introduction
2.1 –Overview
APL-LFP lithium ion battery is a battery pack with advanced LiFePO4 technology and intelligent
integrated BMS, which has the advantages of long cycle life, light weight, small size, safety and
environmental protection. APL-LFP lithium ion batteries can be used in a variety of indoor and
outdoor applications.
2.2 –Working Principle
The communication standby power supply consists of several lithium iron phosphate battery
units in series with the dedicated high performance and high reliability battery management
system (BMS).The +/- output terminal of the battery is connected to the +/- terminal of the
rectifier. When the mains supply is normal, the telecommunication equipment is supplied by
mains rectified power, and the battery pack is charged by rectified power. When the mains
power is interrupted, the backup power supply will be supplied to the telecommunication
equipment without delay to ensure that the power supply of the telecommunication equipment
is not interrupted until the mains power supply is restored or BMS automatically starts to protect
the power failure due to over-discharge protection.

APL48-50LFP liFePO4 Battery Operation Manual
2.3–Battery Management System (BMS)
Integrated Smart BMS technology is adopted for battery modules of APL-LFP to assure smart
automatic management for batteries. Features of BMS are shown as below:
Overcharge Protection
When the voltage of any cell is greater than the overcharge detection voltage and the duration
exceeds the delay time of the overcharge detection, the protective plate judges that the over-
voltage state occurs and the charging MOSFET is closed, charging to the battery pack is
prohibited.
When the voltage of the highest cell after overvoltage occurs restores to the overcharge recovery
voltage or below, the protection plate judges that the over-charge state has been relieved. At the
same time, the charging MOSFET is turned on, the charger can charge to the battery pack, and
the green RUN light on the protection plate shines during charging.
The battery pack can still discharge to the load when the overvoltage state occurs.
Over-discharge Protection
When the voltage of any cell is less than the over-discharge detection voltage and the duration
exceeds the delay time of the discharge detection, the protective plate judges that the over-
discharge state occurs. The green RUN lamp and red ALM lamp are both extinguished, discharge
MOSFET is closed, and the battery pack is prohibited to discharge to the load.
When discharge under-voltage occurs, the protection plate goes to sleep, and the charging input
can be waked up by adding a charger.
Overcurrent/short circuit protection and recovery
When the discharge current exceeds the short-circuit protection current and the duration
exceeds the delay time of the short-circuit detection, the red ALM lamp is glitter, and the
protection plate enters the over-current protection/short-circuit protection state, under which
charge-discharge is prohibited.
After the protection plate enters the overcurrent/short circuit state, it will lock the state until the
charging input can be activated by adding a charger.
Heat Management
With the function of cell and environment temperature detection, when the temperature is too
high or too low the product will start up alarming and protection function. The temperature
sampling accuracy is less than ± 2°C within the operating temperature range. Four battery
temperature detection points and one ambient temperature detection point (maximum 16
battery temperature detection points) are supported by default.

4
APL48-50LFP liFePO4 Battery Operation Manual
When the temperature of the NTC drops to the set value of recovery over-temperature, the BMS
recovers from over-temperature state, and the red ALM light extinguishes.
APL48150LFP is equipped with heater, sampling temperature is 0℃~ +10℃when charging,
sampling temperature is below 0℃when standing, heater power supply is 100W, heater starts.
Heater is optional for other models.
Battery capacity calculation function
Cell algorithm: About the use of soc and soh, soc uses the basic elements of the Ampere
integration and OCV method. The Ampere integration method and voltage, by the adjustment of
the algorithm, with higher precision data and Independent clock system, ensures reasonable
display during a single cycle. And the SOC estimation accuracy is ≤± 2%.
Balancing Function
When the battery pack is charged, if the cell voltage reaches the equalization turn-on voltage,
and the maximum voltage difference is greater than the equalization voltage difference, the cell
that meets the condition turns on the equalization function. Battery supports up to 7 channels
simultaneously to turn on equalization. The maximum equalization current is about 75mA.
Balance will stop when charging stops or the voltage difference of the cell is less than the setting
value.
Sleep and Wake Function

Remark
