Thanks to high-capacity passive balancing system, V-IQ battery management system presents all monitoring and safety functions that are needed in lithium-based battery packs together.

V-IQ system can easily be used in battery groups having up to 60 cells. In addition to this, V-IQ system also includes up to 20 temperature sensor and 10 current sensor inputs. The system includes internal temperature relay and also outlet for charge and discharge relays.

Thanks to its special software, V-IQ battery management system enables all functions within the system to be programmed flexibly. The specific procedures, including the warning/alarm levels, can be programmed to any level. In addition to its unexampled unique specifications, V-IQ battery also enables battery characteristic to be programmed as well. Thus, V-IQ can track state of charge (SOC) and state of health (SOH) at full length.
