Adhering to the business philosophy of "pursuing the perfection of products, helping the cause of environmental protection and harvesting a beautiful sky", extreme space technology has written a new chapter in the electric vehicle industry and contributed its own strength to the cause of environmental protection!
JKBMS has professional Battery BMS/Battery Balancer/Battery monitors engineer team to desing high quality series BMS/Balancer/Monitors support Bluetooth/RS485/Wifi/RS232/TTL232/CANBUS for different application. Custom developments are welcome to contact our sales team and engineer team.
JK BMS held a professional BMS engineer team have more than 10 years experience in the electronics/battery BMS field, strength to design and produce the most inavative and high quality active battery balancer and active balancer BMS for li-ion,lifepo4, NMC, Ni-MH,Ni-Cd, Lead acid batteries, red-flow batteries, VRLA and AGM batteries,etc.. The JK balancer and BMS are using active balancing technology which is not wasted but redistributed within the battery. Since there is no waste heat like passive balancing, cooling for this is no longer necessary. With comparable performance less space is required. The optimally balanced battery increases the service life considerably.
Our professionals are always at your service if you require technical support, software activation for one of our products, or if you are missing some documents, like a user manual.
A lithium battery smart BMS, designed for big capacity series lithium battery packs, is a management system that provides a range of features, including voltage collection, active large current balancing, overcharge, overcurrent, overtemperature protection, Coulombmeter, Bluetooth connectivity, GPS remote, and more. Our BD6A24S12P Active Balancer BMS offers a range of benefits, including high current active balancing technology, maximum battery consistency, longer battery life, and delayed battery aging.
Key Features
he JK-B2A25S-RP battery management system (BMS) is intended for largecapacity (high current and many cells in series) lithium battery packs. It can be configured to operate with other battery types such as ternary lithium, lithium Titanate (LTO) etc.
The system supports 3 to 25 cells connected in series. The JK-B2A25S-RP performs the standard BMS functions i.e. protection against : over/under cell temperature, over charge or discharge currents,
over/under cell voltages In addition the JK-B2A25S-RP also performs an active cell balancing function. Active balancing takes energy from the highest charged cell (cell with highest voltage) and transfers this via a super capacitor to the cell with the lowest voltage.
Being active no energy loss is experienced in the process (passive balancing uses resistors to balance but this creates a lot of energy loss). Balancing happens as long as the BMS is connected to and powered by the
cells. Balancing avoids situations where adjacent cells can be over and under charged (i.e. 3V and 3.6V iso both being 3.3V) Balancing (after enough time to perform the function) maintains the cell
voltages withing 5mV to 10mV (adjustable) from each other. Balancing improves the available capacity and the overall lifespan of the battery. Unlike smaller capacity BMS units, the JK-B2A25S-RP does not include internal semiconductor switching elements to disconnect the battery if a fault condition occurs.
Disconnecting is achieved via externally installed high current solenoids (relays). Depending on the requirement up to 3 of these solenoids might be needed (pre-charge, over charge, over discharge) The solenoids are not supplied with the BMS and these needs to be externally sourced.
The JK-B2A25S-RP has built in Bluetooth support allowing you to set parameters and monitor the status of the cells. A matching Android/Apple App needs to be installed

Can Bus Operation
The JK-B2A25S-RP has a built in STM32F103 class
microcontroller. It supports CAN bus communications as
per CAN2.0A standard at 250kbps. The BMS transmits
status information only (it does not receive or respond to
any messages). The message cycles and ID’s are as
follows:

The JK-B2A25S-RP battery management system (BMS) is intended for large-capacity (high current and many cells in series) lithium battery packs.
It can be configured to operate with other battery types such as ternary lithium, lithium Titanate (LTO) etc.
The system supports 3 to 25 cells connected in series.
The JK-B2A25S-RP performs the standard BMS functions i.e. protection against:
a) over/under cell temperature,
b) over charge or discharge currents
c) over/under cell voltages
In addition the JK-B2A25S-RP also performs an active cell balancing function.
Active balancing takes energy from the highest charged cell (cell with highest voltage) and transfers this via a super capacitor to the cell with the lowest voltage.
Being active no energy loss is experienced in the process (passive balancing uses resistors to balance but this creates a lot of energy loss).
Balancing happens as long as the BMS is connected to and powered by the cells.
