Overview:

  •  8S 24V 15A PCB is used for 8 series 24V battery pack.

  • We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer, etc.

  • The main functions are: overcharge protection, over-discharge protection, over current protection, short-circuit protection, temperature protection, etc.

  • According to the customer request, we can develop PCM in different sizes and structures.

  • BMS manufactured by high-quality Mos and IC imported. Keep your battery long cycle service lifetime.

 Advantage:

  • Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.

  • Strong load ability, constant discharge current 15A use of high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help to cool.

  • IC itself has a power balancing function. The circuit is simple and reliable.

  • Typical voltage detection for each cell. So each battery will be prevented over charged or over-discharged. Over current and short circuit protection function is very reliable. A long-time short circuit of the load won’t affect the PCB and the battery. Temperature protection during charging and discharging.

  • Extreme low power consumption. The consumption of the whole device is less than 50uA.

  • PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.

FAQ:

1. What is the common port and separate port? what is the difference?

  • We take 13S 48V16A BMS as an example, common port 16A means your charge cathode and discharge cathode are connected in the same point end (P-) common connection port, so the charge current and discharge current are the same 16A.
  • The separate port is separately connected by charge cathode (C-) and discharge cathode (P-), so the charge current and discharge current are different, discharge current 16A, charge current 8A.

2. What is the balance function?

  • The working principle and function are as followings, when your one cell voltage is up to alarm voltage(Li-ion up to 4.18V, Life Po4 up to (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will start a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po43.6V)are only in charging status, no discharging.
  • when the fast cell voltage is reached to alarm voltage (Li-ion 4.25V, Life Po43.75V)BMS starts off power protection, all the other cells are all in stop of charging, this process will enable your battery charging in balance current, and your battery voltage is in balance status, but when your cell voltage difference is in a big range, then balance can not be functioning well

3.The relationship between Battery capacity and BMS current?

  • There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on continue current, that is to say, if your engine is powerful, you should choose high current of BMS, it does not rely on battery capacity.

4. What type of charger should I choose?

  • Lithium battery must choose a specific charger, do not use Charger for Lead-acid battery, for leadacid charger may have MOS with high-pressure breakdown protection, which will not protect of BMS overcharge.
  • Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X 4.2V.

5. Whether my BMS damaged?

  • If you want to judge if the BMS is damaged, please take the following steps to test if each cell voltage is the same with a voltmeter

  •  if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displayed as no charge, no discharge, no discharge while the battery has voltage.
