Introduction

PUSUNG series is a professional storage battery pack solution designed and produced by SEPLOS. PUSUNG-135 is designed to fit SEPLOS 3.2V 135Ah prismatic cells with high safety ratings and better performances.

Features

• Suitable for SEPLOS 3.2V 135Ah LiFePO4 prismatic cells.
• Battery cell is made from lithium iron phosphate (LiFePO4) with safety performance and longer cycle life.
• Performance update: laser welding to improve performance
• Safety update : Add a trip breaker to offer double protections. If the the BMS MOSFET malfunctions, BMS will send control signals to the trip breaker, and the circuit will be cut off in case any unexpected conditions.
• BMS has over-discharge, over-charge, over-current, high and low temperature warning and protection functions.
• BMS monitors the charge and discharge state, and balance the current and voltage of each cell.
• BMS comes with upper computer system for real-time cell and pack voltage, current, temperature, and battery status monitoring and recording.
• Flexible configuration, max. 16 packs can be connected in parallel for expanding capacity and power with 8 DIP switches.
• Pre-programmed with multi-protocols, SEPLOS PUSUNG-135 51.2V 135Ah works with multi-brands of inverters. Check the communication inverter list.

Interfaces

RESET
Reset button: to start the battery pack, hold the button for 2s to turn on battery pack.

RS485
RS485 communication interface: RJ45 port, follow RS485 protocol. For transmitting battery pack information between paralleled packs. The first 4 DIP switches (#1, #2, #3, #4) are used for identifying packs’ information on software.

CAN
CAN 5 communication interface: follow CAN BUS protocol, for output pack information to inverter. One pack should be assigned as master pack. And the last 4 DIP switches (#5, #6, #7, #8) to tell how many slave packs are followed. The firs DIP switches are used for identifying slave packs.

ADS
ADS Switch: To setup battery address for identification, and make the communicate between batteries, battery to inverter.

NOTE : There are 8 bit DIP switches, keep the switch on down side means ‘OFF’, turn up the switch to top side means ‘ON’.

ALARM
ALARM light: red LED flash to show the battery alarm status. And red light to show the battery in protection status of abnormal temperature, over-current, or short-circuit.

RUN
Working light: green LED to show the battery working status. Details as follows,

CAPACITY
SOC light: 4 green LED lights to show the capacity status of battery pack. Each LED represents 25%the capacity.

P+/P-
Power terminals: two pairs of power terminals with the same function, one connect to equipment, and the other one parallel to other battery pack for capacity expanding. For a single pack, both terminals can achieve charging and discharging functions.
Power cable uses 6.0mm power plug with lock button. And can be full rotation.

Trip Breaker
Trip breaker: cut off the circuit automatically when malfunctions occur when in the following conditions.
When the temperature sensor fails, When the voltage or current protection fails.

Cell Features

Specifications
SEPLOS 3.2V 100Ah lithium iron phosphate (LiFePO4) aluminum case prismatic rechargeable battery cell.

Initial Internal

Resistance（1KHz）

| ≤0.33mΩ

Refer to the cell specification for more detailed information SEPLOS Technology applies high quality Grade A cells inside the battery box. And did the following designs to prolong the battery pack cycle life. Judging by the current testing report below, if the battery pack charging and discharging at 0.5C, the battery pack could reach a cycle life of 6000 times or more at the remaining capacity of 80% capacity state at 25℃ room temperature, 100%DOD.

Advanced Battery Management System (BMS)
The BMS is applied to monitor current, voltage, temperature, protection against over-charge, over-discharge, over-current, over-temperature, under- temperature and short circuit. The BMS provides cell balancing and current limitation during charging process to ensure a reliable safety and performance.

BMS Functions

• Over charge protection
• Over discharge protection
• Over current protection
• Cell balancing
• Temperature protection
• CAN and RS485 communication
• Trip breaker control

BMS will cut off the circuit if there’s any malfunctions of temperature, voltage, or current. Refer to the BMS specification for the detailed information

Monitoring software
Battery pack can be remotely monitored with SEPLOS BATTERYMONITOR software. With this software, battery voltage, cell voltage of single cell and pack, SOC status, cell temperature, voltage differences can be monitoring in real time. Through history record, battery status can be checked afterwards. First, connect PUSUNG to the master computer with USB-RS485 adapter. If the adapter needs wiring, follow the wiring diagram.
