[Environment]Electric Powertrain Systems

In recent years, vehicle electrification has seen remarkable progress, due in part to environmental regulations on zero-emission vehicles. In addition to Hybrid Electric Vehicles (HEV), Plug-in Hybrid Electric Vehicles (PHEV), and Electric Vehicles (EV), Mild Hybrid Vehicle systems using 48 volt electricity are starting to appear.Vehicle electrification systems will prove essential for meeting environmental regulations. In addition to the main electric powertrain components of electric motors, inverters, and lithium-ion batteries, we are developing other technologies to maximize eco-friendliness and driving performance.

Key Technologies

Electric Powertrain SolutionsIn

In order to respond to the growing demand for electric powertrains, we aim to address various market needs by developing technologies such as electric motors, inverters, and lithium-ion batteries. We use rectangular wiring to create motors that produce high torque with a reduced torque ripple, yet remain very compact. In addition, by using double-sided direct-cooling power modules, we can produce compact and lightweight inverters with a high output, thereby meeting a diversity of needs.

Lithium-ion Batteries for Electric Vehicles

A key to improving the performance of electric vehicles is improving the performance of lithium-ion batteries by reducing charging time while increasing output and capacity. We can meet a wide variety of system solution needs, from 48V lithium-ion battery packs that offer both high output density and high energy density for use in Mild Hybrid systems that assist gasoline engines, to batteries for High-voltage Hybrid systems.
