Service developed to support decision-making for corporate EV fleet adoption

Formulating optimal deployment plans by visualizing operating costs and CO2 reduction

JA Mitsui Leasing, Ltd. and JA Mitsui Leasing Auto, Ltd. , Fujitsu Limited, and Smartvalue Co., Ltd.  have jointly developed a service to support optimal decision-making for electric vehicle (EV) adoption in corporate fleets, and the JA Mitsui Leasing Group will launch this service as the “EV Simulation Service” (the Service).

The Service leverages real-world driving data obtained from Smartvalue’s telematics system “CiEMS Plus”  and Fujitsu’s Social Digital Twin. The service simulates multiple scenarios for EV adoption—from vehicle model selection and fleet sizing to charging infrastructure and operational methods. By visualizing the economic viability and operational efficiency of EV deployment, it supports the formulation of an optimal EV deployment plan.

Background

Amidst the transition to a decarbonized society and an unstable energy landscape, the electrification of corporate fleets has emerged as a critical management challenge. However, contemplating EV adoption involves numerous factors such as driving range, charging infrastructure availability, compatibility with existing vehicle operations, and upfront and operating costs, all of which complicate making optimal deployment decisions.

To address these challenges, the four companies have, since November 2024, conducted extensive verification  of EV adoption impacts for corporate fleets, including the JA Group, aiming to create an environment where corporate customers can make EV deployment decisions tailored to specific operational conditions.

Service Overview and Value Proposition

This service was developed based on insights derived from the four companies’ verification efforts to date. By leveraging real-world driving data from “CiEMS Plus” to analyze vehicle usage patterns and business characteristics, the service proposes an optimal EV deployment plan from both economic and operational standpoints. Specifically, it comprehensively and automatically simulates optimal vehicle model selection, fleet size, the necessary scale of charging infrastructure, and charging methods. Concurrently, it integrates and visualizes the reduction in CO2 emissions and total cost of ownership (TCO), presenting multiple scenarios for comparison.

Traditionally, EV deployment planning has often relied on desk-based analyses stemming from individual assumptions and projections. This service, by leveraging actual driving data to digitally replicate vehicle operations post-EV deployment, enables simulations that more accurately reflect real-world conditions. Consequently, customers can formulate EV deployment plans precisely tailored to their actual operations, thereby reducing the risk of over- or under-deployment and additional investment, while also contributing to overall business improvement through enhanced vehicle operational efficiency.

Roles of Each Company

• JA Mitsui Leasing GroupPlanning and provision of this service by leveraging its customer base and asset management capabilities in the mobility sector.
• FujitsuUtilizes Social Digital Twin to simulate the selection of optimal vehicle models, the number of vehicles to be introduced, charging infrastructure, and operational methods.
• SmartvalueProvides a platform for acquiring and managing vehicle data via telematics services, and collects data such as location information and driving history required for this service.
