QUICK DETAILS

INTRODUCTION 

JBD-AP21S002 is a software protection board scheme specially designed for 7~21 strings of lithium battery packs. The product adopts architecture of front-end acquisition chip + MCU, and some parameters can be flexibly adjusted through the host computer according to customer needs.

current)
200A 300A
Consumption of
running
≤300mA
Consumption of sleep ≤1000uA
Sleep conditions Delay 65000s under no current \ communication \ protection
state (settable)
Circuit resistance) ≤10mR
Operating temperature -30℃~75℃
Size 200±2mm * 114.5±0.5mm * 51±1mm

Supplementary note:

Continuous standing for 65000s (settable) will automatically disconnect therelay and reduce the standby power consumption of BMS. A large charge discharge current will be identified through the pre charge discharge circuit, and then close the relay.

First one installed

This is the first JBD BMS that I have installed. I was very impressed with the quality and assembly of the unit. It would be very helpful to have a detailed wiring schematic included with the unit. We are building a 12s 36 volt 304 ah battery and cannot find a wiring schematic for that voltage. We have it paired and all inputs entered however it says it has 14 cells and we can not change it to get a cell voltage read out. Still working on it.

RS485

Will this unit work with the JBD-LCD02-RS485? I keep getting a ‘Connection Error’ message on the screen. This connects using the RS485 connector on the left side of the circuit board.
