Sojitz Corporation (Head Office: Chiyoda-ku, Tokyo; Representative Director: Masayoshi Fujimoto; “Sojitz”), NGC Corporation (Head Office: Koto-ku, Tokyo; Representative Director: Masatsugu Hashimoto; “NGC”) and OMRON SOCIAL SOLUTIONS CO.,LTD. (Head Office: Minato-ku, Tokyo; Representative Director: Toshio Hosoi; “OSS”) have developed a cloud-based charging control system to optimize charging for commercial electric vehicles (EVs/PHEVs*¹). The cloud-based charging control service will help users to avoid unnecessary capacity charge and simultaneously ensure optimized EV fleet charging operations. The service will be launched from November 10, 2022.

[Concept of the Cloud-based Charging Control System] 


Japan’s Ministry of the Environment has framed a policy for achieving carbon neutrality in Japan by 2050*² which accelerates the transition to 100% electric car sales by 2035.² The EV market is expected to demonstrate rapid growth in the coming years.

In recent years, the transition to EVs has accelerated, particularly for transportation vehicles, official vehicles, and commercial vehicles. EVs operated during the day need to be fully recharged by the next morning. If all vehicles are simultaneously charged when returned to the base, there is a risk of power peaks (demand peaks) occurring that drive up capacity charge.

Sojitz, NGC, and OSS will provide a solution to achieve efficient charging for commercial EV and PHEV users. The new cloud-based charging control service developed by the three companies makes it possible to distribute energy as needed to optimize charging and help the facility to avoid unnecessary capacity charge.

This service enables multiple vehicles to be equally charged before use the next day through  the NGC cloud-based charging system (patent pending: application 2022-107789) and the “EV charger controller” developed by OSS. The charging control system ensures the smooth operation of EV fleet for next-day use utilizing digital transformation technology. Sojitz promotes green EV infrastructure businesses (to offer EVs designed to be recharged from renewable energy as part of a package with the necessary infrastructure) leveraging its experience with the development and the operation of renewable power plants.

NGC, OSS, and Sojitz will take on this new initiative together to demonstrate strong leadership in the growing EV/PHEV market by leveraging their respective strengths, which include NGC’s planning and agile software development capabilities, OSS’s many years of experience in the energy business with energy storage system controls and power grid interconnection technology,*³ and Sojitz Group’s extensive networks.

Sojitz, NGC, and OSS provide new value through technology-related innovation, and this business alliance offers energy efficient solutions such as V2H and storage battery control services.

[Role of Each Company]
Sojitz: Sales, implementation, operation, and maintenance of charging control services towards EVs/PHEVs
NGC: Development and technical support for cloud-based EV charging system
OSS: Development, manufacture, and technical support for EV charger controller

[Characteristics of the Service]
A cloud-based control system enables to identify individual vehicles and distribute power for multiple vehicles that;
Enables all vehicles to be equally charged while avoiding unnecessary capacity charge
Allows to collect and analyze data on remaining charge and charging capacity in real time
・ Prevents electricity theft by unknown vehicles
The system contributes for smooth operation of EV and PHEV fleet without major changes.
