3 – 6 Cell Active BMS Module

V-ACT presents the active balancing technique commercially for the first time in the world. In addition to the fact that the “Active Battery Management System” that was developed enables high-capacity balancing speed, it is able to preserve 99 per cent of the total energy of the group. The energy conversation structure of the system prevents the heat production. Thanks to this property of the system, V-ACT modules can be mounted to DIN rails.

Standard V-ACT modules include 6 cell voltage measurement, 2 temperature measurement and all other equipment necessary for the active balancing of all cells. The modules also include optional analog and digital current sensor inputs. By uniting an adequate number of V-ACT module by means of the intermediate connection cables, you can create the battery management system that you need. Thanks to the characteristic of V-ACT configuration software and battery group, you can program the warning and alarm functions and also view the management data in the system.
