What E Mobility Power does

E Mobility Power (株式会社e-Mobility Power) is a Tokyo-based EV charging infrastructure operator and a subsidiary of the Tokyo Electric Power Group (TEPCO). Established in 2019 and consolidating the legacy EV charging operations of TEPCO — including the 2023 absorption of Japan Charge Network (JCN) — the company operates Japan's largest public EV charging network, with approximately 9,600 rapid charger ports deployed across expressways, convenience stores, commercial facilities, service stations, public roads, and residential complexes. It serves two primary customer groups: individual EV and PHEV drivers (via the eMP card and eMP mobile app) and B2B charger-owning partners who install and connect chargers to the eMP network under general partnership (一般提携) agreements.

The company's technology platform is centered on the CHAdeMO DC rapid-charging protocol, in whose development e-Mobility Power has historically played a core role. It operates the eMP Unified Authentication System enabling single-card or app-based access across nearly 10,000 ports, supported by real-time availability data, charging history, and both time-based (¥/min) and energy-based (¥/kWh) billing. Proprietary hardware co-developed with strategic partners includes the award-winning Blue Multi rapid charger (Nichicon, 2020 Good Design Award), the Red Multi 4-port rapid charger (Nichicon, up to 150kW per port, deployed January 2025), and the SERA-400 ultra-rapid charger (Toko Takuma + Sumitomo Electric, 350kW per port, world's first CHAdeMO 2.0.2 certified, unveiled May 2025). The company also supports the international OCPP standard for charger management and interoperability.

The business model combines recurring membership fees (¥4,180/month combined rapid+normal plan; ¥1,540/month normal-only plan), per-minute usage fees (¥27.5/min rapid, ¥3.85/min normal for members, with higher visitor rates), and one-time registration fees (¥1,980). Revenue is generated across B2C consumer charging and B2B partner relationships with anchor clients including FamilyMart (~700 store network — largest convenience-store charging footprint in Japan), Kohnan Merchandising (32 home improvement stores, up from 10 in 2015), Daito Lease (34 commercial facilities), Cosmo Oil, Keio Electric Railway Bus, MK Taxi, Ryohin Keikaku / Life Corporation, and Yokohama City (government public-road charging pilot). Sales motion blends product-led growth (eMP app, driver portal, content marketing) for individual drivers with direct enterprise sales for charger-owner partnerships.

Revenue model

1. Monthly Membership Fees (急速・普通併用プラン): Members pay a monthly subscription fee of ¥4,180 (tax-inclusive) for the combined rapid and normal charging plan. This provides access to discounted per-minute charging rates. The plan requires a 6-month minimum contract with a ¥1,980 cancellation/plan change fee if terminated early.
2. Per-Minute Charging Fees (Time-based Billing): Revenue is generated from per-minute usage fees billed to members and visitors. Rapid charger rate: ¥27.5/min (¥25.0/min ex-tax). Normal charger rate: ¥3.85/min (¥3.5/min ex-tax). These rates apply to the combined plan members. Visitor (non-member) rates are higher per the visitor fee schedule.
3. Visitor (Non-member) Charging Revenue: Non-members can use chargers as visitors (ビジター利用) without a monthly fee but pay higher per-use rates. Requires smartphone and Japanese-issued credit card for each session. This provides a freemium-like acquisition pathway converting occasional users to members.
4. Registration/Enrollment Fee: One-time registration fee of ¥1,980 (tax-inclusive) for new member enrollment. Additionally, card reissuance carries a ¥1,980 fee.

Direct peers

• ChargePoint: Operates one of the world's largest EV charging networks with a similar model of operating an open network connecting partner-owned chargers via unified authentication and cloud software. Directly comparable in business model (network operator + hardware agnosticism) and target customers (EV drivers and site hosts), though ChargePoint is US-centric and has global reach.
• EVgo: US-based public DC fast charging network operator with a focus on rapid charging and a comparable subscription + per-minute pricing model. Similar capital-intensive network operator model serving EV drivers and commercial site hosts, though operating in the US with CCS/NACS standards rather than CHAdeMO.
• Electrify America: Operates one of the largest DC fast charging networks in the US, focused on ultra-rapid charging. Comparable in scale and rapid-charging orientation to eMP's network, though serves a different geography and uses CCS standards.
• Allego: European public charging network operator providing a pan-European charging service to EV drivers with unified authentication and roaming. Directly comparable in business model (network operator with subscription + usage fees) and target customers, though focused on EU markets with CCS standards.
• Ionity: European ultra-rapid (350kW) charging network joint venture among major automakers (BMW, Mercedes, Ford, VW, Hyundai). Closely comparable in high-power charging technology and OEM backing structure (similar to eMP's TEPCO + Toyota/Honda/Nissan/Mitsubishi investor base).

Broad incumbents

• ABB E-mobility: Global EV charging hardware manufacturer offering AC and DC chargers including ultra-rapid 350kW+ units. Comparable as a hardware competitor in the same ultra-rapid charger category as eMP's SERA-400, though ABB is a much larger diversified industrial player rather than a network operator.
• EVBox: European EV charging hardware and software provider offering a full-stack solution to site hosts. Comparable in offering network management software and charging hardware, though primarily serves European markets and emphasizes Level 2 / destination charging over ultra-rapid DC.

Emerging players

• Tritium: Specialist DC fast charging hardware manufacturer with strong position in 350kW ultra-rapid chargers. Comparable technology positioning (350kW hardware), though Tritium is a hardware-only vendor and not a network operator.

Regional players

• ENEOS: Japan's largest oil refiner actively building out EV charging infrastructure at its service stations, directly competing with eMP in the Japan market. Comparable as a charging network operator in the same geography, though ENEOS is a much larger incumbent energy company leveraging its existing service station footprint.

Others

• Nissan: Investor in e-Mobility Power and original developer of the CHAdeMO standard together with TEPCO. Closely tied to eMP as both a strategic shareholder and ecosystem participant (Nissan LEAF vehicles depend on CHAdeMO charging), making it an important enabling/partner relationship rather than a direct competitor.
