Outline

DENSO has been engaged in the development of electric vehicle systems that are ecofriendly and enable even more comfortable travel. As a result, DENSO has realized high functioning compact, and fuel-efficient products that are essential for hybrid vehicles and is producing these products around the world. Going forward, we will leverage our expansive business domains to form linkages between various in-vehicle systems and products in an effort to efficiently manage energy within vehicles. In this manner, we will further improve fuel efficiency, contribute to the conservation of energy and future net zero carbon society.

Efforts toward New Products That Improve the Driving Distance of Electric Vehicles
Electrically driven vehicles such as plug-in hybrids and electric vehicles consume a large amount of energy for indoor heating. Accordingly, maintaining long driving distances is one major issue with these vehicles. As a technology that can be used to solve this issue, we have been developing and commercializing a heat pump system that controls energy consumption by using heat from outside air as a heat source. This system has already been installed in the Toyota Prius PHV. In 2018, this system was also installed in the Subaru Crosstrek Hybrid in the United States. Furthermore, we have developed a new electric truck freezer for heavy-duty trucks that applies this heat pump system technology and improves energy efficiency by 20% compared with conventional systems. This system has been installed in HINO PROFIA COOL Hybrid trucks since June 2019.

■ Growth Targets
Drawing on our No. 1 share of clients around the world and our regional development capabilities, we will develop and introduce products that offer new value (with reduced fuel consumption, increased comfort, and comprehensive heat management) and work to expand sales of core products in emerging countries, such as car air-conditioners and radiators. By doing so, we aim to achieve stable growth that is parallel to the growth of the global automotive market.

Developing a Small, High Output Ignition Coil That Improves Fuel Efficiency
Through the development of small core technologies, we created CRICs 100 (CRICs: Coil Revolution Internal Combustion series), a small, high output ignition coil that achieves world-leading energy utilization and energy efficiency (volume ratio). Mass production of CRICs 100 commenced in October 2018.Lean combustion is required to improve the fuel efficiency of gasoline engines. However, lean combustion can make it difficult to ignite fuel. Our products are able to steadily ignite fuel using high ignition energy, thereby enhancing engine efficiency.

■ Growth Targets
In developed countries, we will promote efforts aimed at enhancing the efficiency of internal combustion engines in the age of electrification and developing new products that contribute to electric vehicles and automated driving. Meanwhile, in emerging countries we will realize optimized specifications using existing products and work to reduce costs. These efforts will in turn contribute to compact, inexpensive vehicles that are eco-friendly. Furthermore, by 2021 we will complete the development of technologies we originally intended to complete by 2025. By expanding our business in emerging markets and entering into new electrification domains, we aim to achieve a stable annual growth rate of 3%.

Contributing to the New Mobile Society with Technologies That Realize Eco-Friendly, Highly Efficient Transportation
We develop and produce key components for electric vehicles, such as motor generators, inverters, and battery ECUs. At the same time, we are pursuing the development of technologies that enhance product efficiency and promote advanced product installation, including the practical application of SiC devices in inverters. For example, we are adapting multi-cell monitoring ICs manufactured in-house for battery ECUs, thereby enabling the highly precise estimation of battery capacity. By doing so, we are able to increase battery capacity by approximately 2%, thereby achieving longer driving distances for electric vehicles.

■ Growth Targets
As the leading supplier of energy management systems for electric vehicles and electric drive systems that allow for superior control over driving, turning, and stopping, we will promote the electrification of a diverse range of mobile solutions, including not only automobiles but also aircraft, with the aim of realizing annual revenue growth of over 20%
