FAQ 1. What is the common port and separate port? Q: 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 connectionport, 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? Q: The working principle and function are as followings, when your
one cell voltage is upto alarm voltage(Li-ion upto 4.18V, Life Po4
upto (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 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 are in
balance status, but when your cell voltage difference are in a big
range, then balance can not be functionning well . 3. The relationship between Battery capacity and BMS current? Q: 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? Q: Lithium battery must choose specific charger, do not use Charger
for Leadacid battery, for leadacid 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 ? Q: 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 inall, continue current
shall be higher than current limitation in Controller. 6. Whether my BMS damaged? Q: if you want to judge if the BMS is damaged, please take the
folowing steps, to test if each cell voltage is the same with
voltmeter? if the cell voltage difference is over 0.1V, the fault
is displayed that it cannot run far, no power supply at thestart
range, short charge time, all these issues are almost caused by
battery cells, if BMS damaged is displyed as no charge, no
discharge, no discharge while the battery has voltage. |
