High-precision vehicle-mounted current sensor (inverter and battery charge/discharge monitoring)
Mass production adoption of inverters for EVs and HEVs and battery management systems at a scale of 1 million units per year. Full custom support is the focus.
This is a current sensor with extensive in-vehicle experience for applications such as drive inverters (AC) and lithium-ion battery charge/discharge monitoring (DC), and it can be fully customized. It uses an original Hall element developed specifically for current sensors, and by adopting a unique compensation circuit, it achieves high precision and high reliability. Due to its low temperature drift, it can be used under harsh conditions across a wide temperature range. *In terms of specifications for each product, customizations for supply voltage and various specification tolerances can be accommodated according to your requests.

Company information
Founded 91 years ago as "Yashima Automobile Parts Trading Company," our company originated from the automotive parts division of Yashima Motor Co., which was the general importer of Chrysler vehicles in 1926. Over the years, we evolved from supplying repair parts to directly providing mass-produced components to automobile manufacturers, in line with the pre-war and post-war trends of domestic automobile production. At the time of our establishment, the Toranomon area was referred to as Japan's Detroit, yet there were almost no domestic vehicles present, and we had been engaged in automotive-related business even before the domestic production of automobiles began. Today, we have transformed and grown into a technical trading company that directly supplies and sells mass-produced parts to major automobile manufacturers and construction machinery manufacturers. We support the development departments of manufacturers with technical proposals and assist the procurement departments with global parts sourcing, providing mass production solutions for a wide range of products, from resin molded products, semiconductors, electronic components, and sensors to inverters and onboard motors that make up electric vehicles. Notably, the next-generation onboard electrification components have significantly increased, with mass production sales reaching an annual scale of 6 billion yen.
