FAQ
.FAQ
1.What is the common port and separate port? what is the difference?
We take 13S48V16A BMS as an example, common port 16A means your charge cathode and discharge cathode are connected in the same
point end(our P-), charge cathode and discharge cathode are used in the common connection port, so the charge current and
discharge current are the same 16A. while 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 starts 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 Po4 3.6V) are only in charging status, no
discharging, when the fast cell voltage is reached to alarm voltage(Li-ion 4.25V, Life Po4 3.75V)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 are in balance status, but when your cell voltage difference are 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, your should choose high current of BMS, it is not relied on battery
capacity.
4. What type of charger should I choose?
Lithium battery must choose specific charger, do not use Charger for Lead acid battery, for lead acid charger may have MOS with
high pressure breakdown protection, which will not protect of BMS over charge.Life Po4 battery charger voltage=battery string
No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
5. What current BMS should I choose ?
Take 10S36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of
controller. eg., choose 16A for below 350W, 25A for below500W, 35A for below 800W, 60A for Below 1000W, higher than 1200W are
contact with our service specialist for suggestions, one in all, continue current shall be higher than current limitation in
Controller.
6. 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
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.
Attention When Connecting:
When we connect BMS with cells or disassemble BMS from battery pack, the following order and regulations must be complied with to
avoid damage of components of BMS and problems of not protecting of cells.
In order to achieve the best performance of BMS and to run the longest distance, all the battery must be matched well (Each
battery voltage difference less than 0.05V, IR difference less than 15 mΩ, capacity differenace less than 30mAh) to make sure the
better consistency of the battery.
Cell must be connected in parallel first, after then connected in series.
Connection:
1. Connect charging /discharging wire, battery pack negative wire.
2. After confirm the wires are connected OK, plug the connector cable in the BMS
Do not plug connector cable in the BMS before connect wire.
Attention, ESD protection during work.
