Chapter 1 Product Overview
PBAT600 battery string sensor is specially designed as highly integrated smart sensor
module for VRLA batteries, can quickly and accurately measure the VRLA’s voltage,
charge and discharge current and other parameters. String sensor uses specified
isolated communication bus, equipped with PBAT61 battery cell sensor, to realize the
real-time monitoring of the entire string of batteries. Real-time control of the actual
operation of the battery string and health status, then promptly found problems during
use battery. Real-time know the actual operation of the battery pack and health status,
and discover the battery string existing problems during using, and realize automatic
maintenance functions. It helps the battery string to keep voltage balance under float
status, so that each unit of the battery to maintain the best active status, improve the
battery life, timely find out the problem battery and maintenance, reduces labor cost
and other maintenance costs, improve the safety of battery use to reduce the accident
rate.
The PBAT600 string sensor can fulfill following functions:
Real-time monitoring of the entire string of battery voltage, charge and
discharge current, Battery string of SOC, SOH.
PBAT600 and PBAT61 series with the use of a dedicated isolation bus
real-time monitoring of each battery voltage, internal resistance,
temperature, SOC, SOH.
Auto-sensing for S/N, without excessive manual intervention and
configuration, reducing engineering effort.
About the PBAT61 program upgrade, you can use the local 600 to upgrade.
Advanced measurement algorithm, no need for high current discharge, to

2
achieve non-destructive measurement.
Balancing function, the battery pack keep voltage balance under floating
status, this allows each battery to maintain the best active state, improve
the battery backup time and operating life.
With PBAT61 collector, it collects the collected data into the register for
use by the background device.
Using RS485 communication with isolated power, safely and stably
By the circular alarm LED with breathing light, users can quickly locate the
fault batteries in the machine room
With the external linked Hall sensor, PBAT61 could measure different
ranges of charge and discharge current
The isolation voltage of communication interface is AC 3750V

3.3 Cell Data Acquisition
The PBAT600 communicates with the Cell using the DL-BUS bus, through COM1 and
COM2 two RJ11 port for collection, each COM port can be connected to the maximum
of 60 cell sensors. The collected data is stored in the internal registers.
Supports one-one cell sensor and one-two cell sensor. Specific configuration
reference “PBAT600 Software Application Manual”
3.4 Voltage Balancing
PBAT600 provides voltage balancing, let the battery string keep voltage balancing
under floating status, So that each cell of the battery to maintain the best active status,
improve the battery backup time and operating life. This function needs to meet
certain conditions to proceed.
1. The battery string status is floating.
2. Balancing function on (default is off).
3. The deviation of the group voltage is higher than the setting balancing deviation.
（Balancing deviation can be configured）
4、Meet time interval of the two balancing（default is 2 minutes）
