Part 1 - Safety & Warning

The TL-LFP series LiFePO4 battery system installation, operation and maintenance should

follow important recommendations in this manual:

▪The equipment must be installed by a licensed electrician.

▪Battery maintenance should be carried out by experienced professionals, fullytrainedinsafety

measuresand aware of the risks and dangers presented by the battery.

▪

Note:

Beware of the risk of electric shock by heavy current in case of battery short circuit!

Before commencing work:

•Remove watches, rings and other metal object from your hands;

•Use only tools with insulated handles;

•Please check if the package box is intact. If the box is damaged - immediately notify the supplier;

•If you find leaking liquid or white powder residue on product –stop the operation.

During the operation:

•Do not place tools or metal objects on the battery;

•Disconnect the mains AC power supply to the battery system;

•Do not use or store the battery near to the high temperature source;

•Avoid open fire near the battery;

•Avoid using liquids or other objects filled with liquid near the battery;

•Do not open or cut the battery;

•Do not to hit, throw or step on the battery;

•Use only special communication cable set between battery module(s) and charging equipment;

•The charge and discharge of the battery must be conducted within parameters set in this Manual;

•The output interface of the battery system is LIVE and under dangerous voltage when the mains

power supply is OFF - beware of electric shock or battery shortcircuit during the operation;

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

℃ -

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.

Remark

In the idle state (no charge, discharge, no

communication), the lowest voltage of any

cell is lower than the set sleep voltage (can be

set), after 30 minutes, enter normal sleep.

When the minimum cell voltage is lower than

the cell over-discharge protection value (can

be set) or the total voltage is lower than the

overall over-discharge protection value (can

be set), and after 1 minute, the under-voltage

sleep is entered.

Communication function

Battery communicate with a computer, server or host through RS485, upload and save the

collected

information. CAN bus communication, 3G/4G communication and Bluetooth

communication can be optioned.

Anti-theft function

When the external load is disconnected, the BMS cannot detect the load resistance, and it will

enter into a locked state, unable to conduct charging and discharging

Note: 1. Please refer to “Specification of each models” for detail BMS parameter setting value.

2. LCD display screen is provided as an option.

3. Anti-theft function is provided as an option.

. Thermal management in low temperature heating and high temperature heat dissipation

is optional.
