01

Portable EV Charger

portable ev charger

Conventional EV charger installation requires foundation work, which poses the problem of fixed installation locations. Link T&B's portable EV charger can be installed anywhere as long as there is a 200V AC (single phase/three phase) or 400V AC (three phase) power source. No construction is required, and you can flexibly place it where and when you need it.

  • No foundation work requiredβ€”install immediately as long as there is a power supply
  • Operates on AC200V (single phase/three phase), AC400V (three phase) β€” No special construction required
  • Portable β€” suitable for events and limited-time installations, ideal for adjusting operating rates
  • Supports retrofit authentication module β€” Plug & Charge possible
  • POC Unit 1 β€” Launched in March 2025

OneChargeKey

Retrofit authentication module - Plug & Charge compatible

Conventional EV charging requires authentication using a dedicated IC card or app. Link T&B's retrofitted authentication module realizes the Plug & Charge method, where automatic authentication and billing are completed simply by plugging the vehicle into the vehicle. Can be retrofitted to other companies' chargers and existing EVs.

  • Plug & Charge β€” Authentication is completed just by plugging it in
  • No card required β€” automatic identification with vehicle ID
  • Can be retrofitted β€” also compatible with existing chargers
  • Compatible with other companies' quick chargers and other companies' normal chargers
  • Visualization of high attribute customers using vehicle ID
  • Real-time collection of charging data

OneCharge

Real-World Data Platform

It is a data platform that collects and analyzes real-world data obtained from EV charging infrastructure and builds a new economic zone that does not depend on charging revenue. By visualizing high-attribute customers using vehicle ID as a key, charging spots can be used as "customer referral points."

  • Real-time collection and analysis of charging data
  • Visualization of high attribute customers using vehicle ID
  • Customer referral/advertisement/data sales model
  • Scope 3 / Non-fossil certificate automatic issuance
  • CO2 reduction report output

With the fusion technology of power electronics and IT, we will change the "normal" of EV charging.

We combine the power conversion technology cultivated through the power electronics R&D business with the software and data technology from the IT & AI Solutions. We have an integrated development system that is unmatched by other companies, completing everything from hardware to cloud in-house.

The roadmap is steadily progressing: technology concept exhibition in 2022 β†’ POC 1st machine in 2025 β†’ JMS2025/Startup JAPAN exhibition. Development is currently accelerating with a view to mass production and full-scale deployment from 2026 onwards.

Scenes of introduction: stores/commercial facilities, event venues, parking lots/car dealerships, offices/condominiums, accommodation facilities/sightseeing spots, construction sites, etc. Because it is a portable charger that does not require construction, it can be used flexibly in any situation.

How Plug & Charge works

Technology

Conventional EV charging requires an authentication IC card or smartphone app. With Plug & Charge, just by plugging in the charging plug, the vehicle ID is automatically recognized and everything from authentication to billing is completed.

Conventional method

  • β‘  Launch the app or touch the IC card
  • β‘‘ Waiting for authentication (several tens of seconds to several minutes)
  • β‘’ Start charging
  • β‘£ Payment processing

Risk of card loss/app failure

Plug & Charge

  • β‘  Plug in
  • β‘‘ Automatic authentication using vehicle ID (instant)
  • β‘’ Start charging & automatic billing

β†’ That's all!

No card required/stress free

Lifecycle Comparison

Fixed vs portable

Compare the entire life cycle of EV chargers, from installation to removal. Portable models do not require foundation work or civil engineering work, greatly reducing the burden of maintenance, relocation, and removal.

Subsidy Scope of application
Subsidy target (main unit purchase cost + installation construction cost)
Subsidy not applicable (removal/relocation/maintenance costs)
Fixed type
EV charger
πŸ—οΈ Several weeks to several months Foundation work + electrical work + civil engineering work is required. For large-scale construction work including asphalt excavation, piping, and frame construction.
πŸ”§ Several days to several months Engineers conduct on-site inspection β†’ parts arrangement β†’ replacement. Long-term downtime occurred.
🚧 Large-scale construction Remove the charger and remove all foundations and piping. Foundation work will be required again at the new location.
⛏️ Restoration to original condition required The foundation was removed, the piping was removed, and the pavement was restored. Removal costs are also high.
Portable
EV charger
⚑ Same day to 1 day No foundation or civil engineering work required. Operation started with only electrical work (installation of outlets).
πŸ“ž Replace with just one phone call In the event of a failure, there is an option to replace the entire unit (advance replacement). Minimize downtime.
πŸ›» Roll and move Just unplug it and move it to another location. No foundation removal or re-construction required.
πŸ”Œ Only seal the outlet Just take the charger home. The outlet is sealed and finished.

Subsidy target (purchase cost + installation cost) Fixed EV charger: High cost, long term Portable EV charger: Low cost, short term

*The expenses eligible for the CEV subsidy (Next Generation Automotive Promotion Center) are the "purchase cost of charging equipment" and "installation cost." Removal costs, relocation costs, and maintenance costs are not covered by the subsidy.

OneCharge ― Real-World Data Platform

Platform

It is a data platform that collects and analyzes real-world data obtained from EV charging infrastructure and builds a new economic zone that does not depend on charging revenue. By visualizing high-attribute customers using vehicle ID as a key, charging spots can be used as "customer referral points."

A three-step economic zone that does not depend on charging revenue

STEP 01 / INPUT

Charging data collection

Real-time data of EV charging is aggregated in the cloud. Analyze usage patterns, length of stay, and location information.

β†’
STEP 02 / ACTION

Customer referral/cooperation

Sends customers to nearby stores and facilities while waiting for charging. Monetize with ads, coupons, and navigation.

β†’
STEP 03 / OUTCOME

New profits/decarbonization

In addition to advertising revenue, customer referral fees, and data sales, Scope 3 compliance and non-fossil certificates are automatically issued.
