Special Features
1.
The BMS24T uses advanced ADC measurement technology, high accuracy, high voltage and high current
detection circuit. The maximum voltage measurements tolerance is within 8mV at up to 24S LiPo battery
(100V)
2.
Supports regenerative braking, during braking operation it can charge the battery pack and the discharge
power (Wh) will decrease in response to the braking power.
3.
Charge/discharge current up to
600A
. Larger current support can be custom ordered.
4.
1.2A
per cell balance current is very useful for large capacity battery pack, this feature can restore all
cell voltage balance in the shortest time. Over temperature protection ensures the system safety during
balancing.
5.
BMS24T calculates and displays the charge and discharge power (Wh), generally the battery rated power
is rated voltage multiplied by rated battery capacity.
6.
TFT LCD screen provides rich information including current, voltage, power, capacity, battery status, SOC
and temperature and so on.
7.
BMS24T features maximum safety protections, within the range parameters that can be setup, BMS24T
will alarm and cutoff charge or discharge according to users’ setup, out of range parameters and
triggered absolute maximum settings BMS24T will force cutoff charge / discharge to protect the battery.
8.
Minimize the power consumption by draw current from all cells or external power supply.
9.
Dual power design, the unit can be powered by all the cells or an external power supply.
10.
Detect cell count at any time, and compare with the count detected when switched on first time. If
inconsistent, the device will alarm and cutoff charge or discharge according to user setup, this is a safety
feature is if a cell becomes loose.
11.
Sound alarm and LED alarm will be triggered if any warning events occur, it will wait several seconds,
then disconnect charge / discharge if required. The delay time can be programmed.
12.
The Charge and Discharge relays are controlled independently.
13.
Two temperature sensors monitor battery temperature for different positions on the pack.
14.
Supports upgrading the firmware program by USB port.
15.
BMS24T provide users the maximum flexibility, key parameters can be programmed.
16.
BMS24T displays battery SOC as a dial gauge. Cell count, battery pack voltage and battery gauge (%)
temperature is displayed simultaneously.
17.
In case the battery pack is not to be charged / discharged and put into
storage mode
, Press STOP
button enter into Sleep Mode to save energy consumption, Charge / Discharge are disabled and the LCD
back light is turned off. Press any key to resume normal work mode.
18.
LCD back light ON time can be programmed to save energy, when it is OFF, press any key to activate.
