AAKEL Provides "EV Charging Optimization System" to Green Coop Kumamoto's 60 EV Fleet

AAKEL Inc. (Headquarters: Fukuoka City, Fukuoka Prefecture, Representative Director: Ryoji Miyawaki, hereinafter referred to as "AAKEL"), which aims to realize a decarbonized society through digital innovation, has begun providing its EV smart charging and operation management system "AAKEL eFleet" (hereinafter referred to as "eFleet") to Green Coop Consumers' Cooperative Kumamoto (Headquarters: Kumamoto City, Kumamoto Prefecture, Chairperson: Kaori Kobayashi, hereinafter referred to as "Green Coop Kumamoto") Northern and Eastern Centers, and to Green Coop Denki General Incorporated Association (Headquarters: Fukuoka City, Fukuoka Prefecture, Chairperson: Yoko Hidaka, hereinafter referred to as "Green Coop Denki").

This implementation optimizes the charging of a total of 60 EV trucks and light EV vans. Through automatic charging control that considers electricity market prices and facility power constraints, it achieves operational efficiency for the EV fleet and optimization of electricity costs.

This initiative follows the implementation at the Western Center (23 EV trucks) in March 2025.

■ Background

Green Coop Consumers' Cooperative, aiming to realize a "Society of Mutual Living," is proceeding with a plan to convert all its business and delivery vehicles to EVs by 2027, implementing the transition in stages at each distribution center.
However, operating a large number of EVs at distribution centers presents operational challenges such as rising electricity costs, balancing overall facility power consumption, and managing charging schedules for multiple vehicles. In particular, distribution centers require a system for efficiently charging numerous EVs within limited charging stations and power capacity.

Therefore, AAKEL decided to provide eFleet to support the optimization of EV operations and energy management.

■ System Overview

■ System Features

① Smart Charging Linked to Electricity Market Prices

Charging is automatically scheduled during times when electricity prices are low, based on price data from the Japan Electric Power Exchange (JEPX).

② Optimal Control for 60 EVs

Charging is optimized for a total of 60 EV trucks and light EV vans, considering their remaining battery levels and planned usage.

③ Optimization Considering Facility Power Constraints

Charging is controlled while suppressing power peaks within the constraint of a maximum of 20 simultaneous charges out of 36 charging stations.

④ Automatic Charging Schedule Management

The system automatically selects vehicles that should be connected to chargers each day, supporting efficient charging operations.

■ Expected Effects

The introduction of this system will achieve the following:

• Automation of EV fleet charging operations

• Reduction in charging costs by utilizing electricity market prices

• Suppression of power peaks at logistics hubs

• Improved operational efficiency to accommodate the expansion of EV adoption

• Reduced costs for expanding electrical equipment and optimization of electrical equipment specifications that do not affect delivery operations

Furthermore, for Green Coop Denki, it contributes to the optimization of electricity procurement costs.

Green Coop Kumamoto, aiming to realize a "Society of Mutual Living," upholds the philosophy of building a society where nature and people, people and people, women and men, and the south and north mutually support each other and live together. Based on this philosophy, each member participates in investment, utilization, and management, working to provide safe and secure products and contribute to the local community.

The service provided by AAKEL contributes to Green Coop's efforts to build a sustainable society and supports the strengthening of environmental protection and community contributions. AAKEL expects its initiatives to support Green Coop's activities and contribute to building a sustainable future together.
