Total solution on E-Vehicle application 

If using the Chargery charger, the charge relay can be ignored, BMS24T can communicate with charger, when 

any  cell  is  over  charged,  BMS  will  send  a  signal  to charger,  the  charger  will decrease  charge  current  till  the 

cell voltage within safe values. If using another brand of charger, BMS24T only OPEN the Charge relay, if the 

charge current is too high, such as over 10A, the relay will open and close repeatedly. The relay life cycle will 

be shortened and charge time will be longer. 

 

 

The Chargery Charger and BMS can save a relay cost and shorten the charge time.

 

 

 

 

NOTE

 

Chargery charger decrease charge current according to “Over Charge Protection(P) Voltage” on BMS setup, so 

please setup the charge terminal voltage setup in accordance with Over Charge Protection(P) Voltage on BMS.
