How do we get accurate battery data using Bluetooth ?
As we all know, the bluetooth display data depends on whether the BMS chip data is accurate. We test the high and low temperature battery status for each series of batteries with different capacities and voltages to obtain the correct CEDV data into the chip.
– Aging compensation
– Self-discharge compensation
Which brand IC do we use?
our BMS adopts Texas Instruments 's chip, grade A .
Do you have certificates?
yes, we have UN38.3 ,CE,MSDS ,UKCA for battery pack ,and UL ,IEC62133 for cells .
