Temperature Sensors for Emobility Applications

Proven supports innovation: Temperature sensors from KYOCERA AVX optimally combine the requirements of new drive systems with tried and tested solutions, and have been designed to anticipate the versatile demands of alternative systems. Established base technologies, proven millions of times in real world conditions, reduce validation processes. They represent dependable components in a highly innovative environment characterised by many unknowns and test risks.

Temperature sensors from KYOCERA AVX determine temperature safely, quickly and precisely in liquid and gaseous media, e.g. water, oil, fuel, intake air and charge air. With more than 20 years of experience in temperature sensor development and production we are partner of well-known OEMs and system suppliers in the automotive industry.

Innovation: Redundant Temperature Sensor
As an automotive supplier for sensors and power modules, our companies have been partners for leading automotive manufacturers and system suppliers for more than four decades. Today, a significant portion of our products is focused on electric mobility and hybrid drives.

If we talk about the range of electric vehicles, the battery is one of the most important elements of future powertrains. Here, too, demanding power densities, accompanied by high temperatures, are becoming the main issue. For temperature monitoring, we rely on a proven technology that, optimized for even better performance, is characterized by an exceptionally long service life. The sensor is designed as a 100 % redundant system for self-diagnostic capability and thus offers optimum safety. With this 100 % redundancy that temperature sensor can be used in systems following functional Safety rules.
