Chapter 1 Product Overview
PBAT61 battery cell sensor is specially designed as highly integrated smart
sensor module for VRLA batteries, can quickly and accurately measure the
VRLA’s voltage, resistance and negative pole temperature. Cell sensors use
specified isolated communication bus, and multiple sensors can be very easily
cascaded to realize the real-time monitoring of the entire strings of batteries.
The cell sensor can fulfill following functions:
Measurement of real-time voltage
Measurement of Internal resistance on line
Measurement of negative pole temperature
Sleep mode to achieve ultra-low standby power consumption
Built-in anti-reverse in put circuit aims to protect the sensor and
battery away from damage even if the power supply is connected
conversely.
Built-in fuse with high reliability and safety
Communication interface’s isolation voltage is AC 3750V
Wiring easily with distributed installation
One PBAT-Gate can support up to 240 cell sensors by cascade
Passive balancing function, the balancing current up to 200mA

Definition
1
V- Bat
Negative power supply, connected directly with the
battery negative pole.
2
V- Sensea
Measuring input of the voltage, connected directly with
the battery negative pole. It contacts with V-Bat.
3
PTC
Temperature sensor input
4
PTC
Temperature sensor input
5
V+ Sensea
Measuring input of the voltage, connected directly with
the battery positive pole. It contacts with V+ Bat.

COM1b
DL-BUS communication，RJ11 interface
8
COM2b
DL-BUS communication，RJ11 interface
Note:
a. The cell sensor uses four-line method to measure the internal
resistance of VRLA.‘V+ Sense’ and ‘V- Sense’ need to be connected
directly with the battery pole. In order to obtain proper measurement
accuracy described in this document, the users should use the
standard factory wire especially for measurement.
b. COM1 connect to the previous node, COM2 connect to the next
node.
