Content 1As Hybrid and Electric vehicles become more mainstream, traditional braking systems are giving way to electrical means of braking such as motors and actuators. These new systems improve efficiency with regenerative capabilities. Isabellenhütte shunts are being used in the 3 phase inverters of the brake motor and in electric park brake systems now widely used in the global light non -electric vehicle market

As electric motors replace old-style pump and hose systems, precision current control becomes crucial. For modern steering systems, Isabellenhütte shunts play an integral role in providing optimal control to drivers, enhancing responsiveness, comfort and fuel economy.


Among competitive electric vehicle producers, battery performance is everything. Battery management systems containing Isabellenhütte shunt-based sensing modules increase the accuracy of voltage and current measurement—helping technology providers supply state-of the-art systems that deliver efficiency and longer battery life.

PHEV, REx, BEV, Full hybrid, mild hybrid, FCEV – the pace of adoption is dizzying and the technology strategies are dynamic across a wide sector of vehicle producers. But whatever the platform, when reliability, precision and long-term stability are required, our shunt resistors and precision measurement systems provide the answer.

Autonomous driving technology requires multiple subsystems, including cameras, radar, lidar and navigation systems—used to set up the structural support for successful autonomous transportation. As these subsystems proliferate, there is a greater need for accurate power management. Our products help you monitor the current and voltage of the batteries—as well measuring power, consumption, and thermal dissipation at the subsystem-level.

Transmission applications, such as automated manual transmissions and dual-clutch designs, require high-performance and high-temperature operation in harsh environments, and the reliability demanded by electronic control systems. Isabellenhütte components help deliver optimal performance under these adverse conditions.

For all types of electric vehicle designs, accurate current measurements are essential to improving the efficiency of the entire HEV/EV drive train. Isabellenhütte components meet the highest specifications of required accuracy, with components of high precision, low drift over extreme temperatures and long-term stability even under harsh automotive conditions.

Many well-known systems and technologies have either been made possible or improved with the aid of our precision resistors and their accurate current-sensing properties. Examples include engine management, fuel injection, driver assistance and energy management systems. In addition, our products are used in many more fundamental vehicle systems, e.g. ignition, lights, water pump, transmissions and modern locking systems.

Building a national EV infrastructure promises to be an important part of the new economy.  Our DC Meters for Charging encompass secure physical designs for public-facing environments, as well as smart technology that delivers essential capabilities for charging, communications, and billing.

Critical to meeting the world’s evolving emissions standards, Isabellenhütte supplies a variety of heating and thermoelectric wires used for the temperature control of tanks, nozzles, and tubes in selective catalytic reduction (SCR) systems, exhaust gas urea treatment solutions, NOx sensors, and other emission reduction systems.


Isabellenhütte supplies a line of high-strength (similar to steel) and high conductivity (similar to copper) fasteners which can be used in “under-the-hood” electro-mechanical systems.  These conductive components can reduce electrical resistance and the generation of excessive heat and loss in system performance. These fasteners are especially effective in close proximity to temperature-sensitive current measuring circuitry. 

Requirements for combustion engines are changing due to tighter emission limits. SCR (Selective Catalytic Reduction) exhaust gas treatments utilize a urea solution to convert harmful nitrogen oxide (NOx) into water vapor and Nitrogen. Isabellenhütte’s specialty resistance wires are used for the heating of SCR tubes, nozzles and tanks to keep the system ice-free and to maintain the exhaust gas treatment’s effectiveness at very low temperatures.

The use of lightweight (fuel-saving) recyclable aluminum in the production of door and body panels in pickup trucks, luxury cars and commercial vehicles has skyrocketed due to it’s high strength and environmental advantages. Isabellenhütte supplies the most stable SLE bare thermoelectric wires used by panel producers for the accurate measurement and maintaining of high temperature during heat treating processes.

Among competitive electric vehicle producers, battery performance is everything. Battery management systems containing Isabellenhütte shunt-based sensing modules increase the accuracy of voltage and current measurement—helping technology providers supply state-of the-art systems that deliver efficiency and longer battery life.


As this technology gains renewed interest for its ability to extend the range of EVs (while maintaining zero-emissions goals) new applications are being discovered in aviation, military and stationary systems. Our dedicated DC sensing modules provide up to IP64 rating for operation in wet environments to accurately monitor the output current of fuel cells.


All types of EV require the inversion of DC from the battery to multi-phase AC for the electric motor which propels the vehicle. It is crucial to accurately measure each phase in order to be able to control the inverter power electronics. Our sensing modules measure high-frequency current and provide a digital output signal to avoid magnetic interference / noise. They can easily be powered using the inverter’s IGBTs / MOSFETs power supply.

Low voltage systems are used in almost every internal combustion, hybrid or electric vehicle, UPS, generator, mining, agricultural and landscaping equipment, etc. They are convenient when functional safety is not an issue, but are limited in the amount of power that can be provided efficiently. 48V systems—in particular— are gaining popularity in hybrid EVs and start-stop-systems. Our low cost non-isolated high accuracy sensing modules are designed to help get every last mile out of your battery.
