Part 2 - Product Introduction
2.1 - Overview
TL Series Lithium-Ion batteries is a range of batteries packed with advanced LiFePO4
technology and possessing intelligent integrated BMS.
The TL battery range has the advantages of:
- Long cycle life;
- Light weight;
- Small size;
- Safety;
- Being environmentally friendly.
Lithium-Ion batteries of the TL Series can be used in a wide variety of indoor and outdoor
applications.
2.2 - Working Principle
The communication standby power supply (module) consists of multiple lithium iron
phosphate battery cells connected in series, and controlled by the dedicated high
performance and high reliability Battery Management System (BMS).
The +/- power output cables of the battery are to be connected to the +/- terminals of the
charging device.
When the mains / solar power is insufficient for the load or is interrupted, the battery will
provide the power supply to the load without delay, until the mains / solar power supply is
restored. In the case of the outage continuing for longer time than the battery has been rated
for - the BMS will disconnectthe battery from the load in order to protect the battery from over-
discharge.

2.3- Battery Management System (BMS)
The TL–LFP Series battery modules are equipped with technologically advanced Integrated
Smart BMS.
Features of the BMS are described below:
Overcharge Protection
When the voltage of any cell comprising a module, is greater than the Overvoltage setting,
and the duration of the Overvoltage status exceeds the set time delay of the overcharge
protection, the OV Protection plate closes the MOSFET on the charging circuit and the
charging is interrupted.
When, after the OV status occurs, - the highest voltage cell indicates the voltage reduction to
the overcharge recovery mode, or below - the OV Protection plate judges that the overcharge
conditionis over. Followingthat, the charging MOSFET is open,the charger starts to supply
the battery module, and the green RUN light on the protection plate lights up signalling that
the charging is ON.
During the Overcharge condition the battery module can still discharge on the load.
Over-discharge Protection
In the case of any cell within the module, developing voltage that is lower than the over-
discharge setting, and such condition lingers longer than the over-discharge time-delay setting
–the protection plate judges that the module is in state of Over-discharge. The green RUN
light and red ALM light are both extinguished, the MOSFET on the discharge circuit closes
and the battery module discharge on the load is interrupted.
When over-discharge (undervoltage) condition occurs, the protection plate is de-activated.
When the charger supply is restored –the protection plate gets re-activated .
Overcurrent/short circuit protection and recovery
When the discharge current exceeds the short-circuit protection current settings, and the
duration of such current exceeds the time-delay of the short-circuit protection setting -
- the red ALM light will come on, and the protection plate enters the overcurrent / short-
circuit protection status, under which charge / discharge modes are prohibited.
After the protection plate entered the overcurrent / short-circuit protection condition, it will lock
the OV/SCprotectionstatus until time the charger restores the power supply.

Heat Management
The thermal management BMS function can be described as follows: if the battery temperature
exceeds the set normal working parameters (higher or lower), the alarm will be raised - red ALM
light will come on and the battery will be disconnected.
When the temperature of the battery, after having been disconnected due to over-temperature
condition, drops to the set value of normal working parameters, the BMS reconnects the battery
to the load / charge, and the red ALM light is off.
The BMS temperature sampling accuracy is less than ± 2°C within the operating temperature
range. Four battery temperature detection points and one ambient temperature detection
point are supported by default. Maximum available number of temperature detection points
–16.
Battery internal heater
VHR TL48150LFP is equipped with an internal heater. The heater is rated 100W. If the battery is not under
charge
and the BMS sampling facility detects the ambient temperature that is below 0 ℃ - the BMS will turn the
heater ON.
The heater is optional for other models.
Battery capacity calculation function
To calculate the State Of Charge (SOC) of the battery –the Amper-Hour Integral and Open
Circuit Voltage (OCV) methods are implemented. The combination of adjustment of the
algorithm, the higher precision data and the independent clock system - ensures accuracy
(≤ ± 2%) of the SOC estimation.
Balancing Function
If the module battery pack is fully charged, and one of its cells has the voltage set to start the
equalization and at the same time, the cell’s maximum voltage difference is greater than the
equalization voltage difference –this cell activates the equalisation function.
The battery module is capable of conducting equalization on 7 channels simultaneously. The
maximum equalization currentaround 75mA. The equalization balancing process will be finished
when the voltage difference of the cells is less than pre-set value.
