eMotion Fleet Implements Proprietary Energy Management System (EMS) for Nishi-Nippon Railroad

eMotion Fleet Inc. (Headquarters: Shinagawa-ku, Tokyo; Representative Directors: Shuji Shiraki, Denis Ilic; hereinafter "eMotion Fleet"), a provider of one-stop services for the introduction and operation of commercial EVs, announces that it will implement its proprietary Energy Management System (hereinafter "EMS") for Nishi-Nippon Railroad Co., Ltd. (Headquarters: Chuo-ku, Fukuoka; hereinafter "Nishi-Nippon Railroad"), with full-scale operation scheduled to begin in April 2026.

This project, at Nishi-Nippon Railroad's Island City Office (Higashi-ku, Fukuoka), which boasts one of the largest bus fleets in Japan, will integrate and manage EV buses and charging equipment from different manufacturers on the cloud, achieving a balance of electricity cost optimization (peak shaving), operational efficiency, and decarbonization.

■ Background and Objectives

Towards achieving carbon neutrality by 2050, the Nishi-Nippon Railroad Group has a track record of introducing over 50 vehicles, mainly "retrofitted EV buses" converted from diesel buses, and aims to continue expanding its EV bus fleet.

With the introduction of domestic EV buses and other models, "integrated management of multi-brand vehicles and charging equipment" and "suppression of power peaks due to an increased number of vehicles (electricity cost reduction)" have become urgent issues. eMotion Fleet's EMS, which excels in energy control highly linked with operational plans regardless of manufacturer, was selected. The goal is to establish a standard operational model for large-scale deployment at the Island City Office.

■ Overview and Features of This Implementation

1. Integrated Support for Multi-Brand Vehicles

The EMS will provide unified management for a total of nine vehicles at the Island City Office, including "retrofitted electric buses" and Isuzu's "Erga EV", regardless of the manufacturer.

2. Automation of Power Peak Shaving Linked with Operational Plans

The system automatically links daily operational plans (timetables) with charging plans, securing the necessary charge for the next day's operations while performing advanced power demand peak shaving through variable output control. Operation managers can entrust complex charge/discharge management and electricity cost optimization to the system simply by performing vehicle allocation.

3. Charging Authentication Linkage to Minimize On-site Burden

The system accurately links combinations of EV buses and chargers from different manufacturers with on-site operations. Drivers only need to plug into an available charger and perform a designated authentication process, completing their preparation. The design prioritizes reducing the burden on staff by eliminating the need for complex judgments or operations on-site.

■ Future Development

Based on the operational results of this project, eMotion Fleet will address the increasingly complex commercial E...
