In xEVs, components are required to be smaller, lighter, more reliable and have higher output.
Therefore, heat management has become more severe and more important than conventional gasoline-powered vehicles.
Our thermistor sensors have an ultra-fast thermal response and extremely high accuracy, enabling improved thermal management, and detecting abnormalities quickly.

In recent years, high-brightness LEDs have been widely used as the light source for automobile headlamps.
However, when LEDs become brighter, heat dissipation and ensuring reliability becomes a major issue.
Mitsubishi Materials’ AuSn paste is a AuSn eutectic solder that is ideal for mounting high-brightness LEDs, and because of its high strength and thermal conductivity, it is a bonding material that boasts a high market share in the mounting of LEDs for headlamps.

A large amount of sunlight and heat rays (near-infrared rays), which cause an increase in the temperature inside the car, enter through the windows and roof of the car. As a result, people in the car feel uncomfortably hot, and the downside is that power consumption increases as the cooling load increases. Mitsubishi Materials' "heat-ray cutting material (ITO)" solves this problem by applying nano-sized ITO particles to windows and roofs. By absorbing and cutting the heat rays (near-infrared rays) contained in sunlight, it contributes to measures against heat in the car and energy-saving measures for air conditioners.

Driving inverters of xEVs in recent years have adopted high-performance power modules.
Insulated heat-dissipating boards that mount power semiconductors in power modules are required to have both reliability to withstand harsh cold heat cycles and heat dissipation to quickly dissipate heat.
Mitsubishi Materials’ DBA®︎ substrate has a track record of being used in a cumulative total of approximately 10 million xEVs because it can maintain bonding quality even in harsh environments with severe temperature changes due to its unique bonding technology.
