The main focus is on achieving dielectric strength that is as high as possible for the intended application. High dielectric strength must be guaranteed in battery-powered vehicles, for example.

The IVT-S shunt-based measurement system has a maximum dielectric strength of 1000V. Its functional range includes the measurement of current and voltage in traction battery systems or stationary electrical energy storage devices. These systems, based on lithium-ion batteries, generate high energy density at which higher voltages can be applied with smaller currents. This is why the sensor’s dielectric strength also has to be correspondingly high − a key quality feature that distinguishes IVT-S. For fast-charging battery systems, this performance feature is extremely important.

Integrated in the IVT-S are a 16-bit analogue to digital converter and a CAN 2.0 interface. Firmware converts measurements charge and discharge data. In addition Isabellenhütte provides a CAN description file in *dbc format that helps IVT-S users to swiftly integrate the application.
