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.

PARAMETERS

Cell specifications  7~21 strings of Lithium Iron Battery
Interface type Charge and discharge are both at the same port
Charging voltage 3.6V*Number of strings
Cell voltage
2.2~3.75V
Continuous charging
current
200A 300A
Continuous discharging
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.

JBD BMS 300 Ampere Technik gut Dokumentation schlecht

Das BMS funktioniert soweit gut es git aber auch einige Fehler , wenn das BMS in die Zellabschaltung geht kann man es nur durch abziehen der BMS Verkabelung reaktivieren, ein Software Update wäre hier von nöten das sich das BMS bei Unterschreiten der Abschaltspannung wieder selbst einschaltet, oder man diese via App wieder das Abschaltrelais aktivieren kann, Auch muss hier an der Dokumentation noch viel gemacht werden, gerade was all die Anschlüsse für funktionen haben wie der Aufbau ist und wie der Anschluss dazu ist hier findet man fat keine Dokumentationen dazu und wenn dann nur in Chinesisch was nicht jeder Übersetzer passend übersetzt, Das BMS selbst funktioniert es macht seinen Dienst , auch fehlt eine Dokumentatin darüber ob man ein Software Update aufspielen kann , der Aufbau und die Instalation war gut die Dokumentation dazu schlecht.

Backup

Been using this BMS for my batteries and installed one for someone else. Got this as a backup.

AP21S002

Quick UK delivery very impressed.
BMS 300A version a little overkill for my needs until I add more batteries.
Initial setup was ok but you must follow the diagram instruction precisely where it shows for instant an 8s cell 6-19 balance cable s must all connect together. I have seen videos where people have claim you cut the excess cables do not the BMS it will not after.
It is an active balancer which means it’s switching is quite audible when it shuts on and off charge or discharge ports respectively. I am having an issue with this switching on and off sound when connected to a 3kw inverter on a lower current than 2Amp. Have tried changing APP parameters to recognised a lower input mA voltage of 50mA but keeps going back to 200mA standard setting which is unhelpful. Not sure if it’s an app issue or BMS range won’t go to 50mA.
Other than this seems to balance much better than other BMS’s. The Xiaoxiang app worked at first then I installed the Elephant App and the App stopped working.
Will update you as soon as these things get fixed.

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.

All right, like again…
