Highway Supercharger Hub

The Challenge

Highway locations often sit at the end of weak grid feeder lines. Installing 4+ ultra-fast chargers can require a costly, multi-year grid reinforcement. At the same time, highway operators need maximum uptime - a single charger fault should not take down the entire hub.

Our Approach

• Grid-plus-storage hybrid: Size the grid connection for average load. Peak demand above this level is covered by the on-site BESS. Reduces grid connection cost by 40-60%.
• 240-480kW modular stations: Each station has 2-4 independently operated charging ports. One port fault does not affect the others.
• Liquid-cooled cables: 500A liquid-cooled cables allow full 480kW without cable overheating - even in 40 degrees C ambient temperature.
• Integrated payment terminal: Standalone operation with RFID, contactless bank card, and QR code. No app required for ad-hoc drivers.
• Remote NOC monitoring: 24/7 fault alerting via OCPP 2.0.1 to your Network Operations Center. Predictive maintenance diagnostics included.

FAQ

How does the BESS buffer reduce grid connection costs?

The BESS absorbs short-duration charging peaks. If your site has a 200kW grid connection and 4x 120kW chargers, the BESS provides the difference during simultaneous charging events. You pay for a smaller grid connection and avoid demand charges.

What is the uptime guarantee?

We design for N+1 redundancy - at least one charger can be down for maintenance without reducing total hub capacity below the service level agreement. We offer 97% uptime SLA for contracted service agreements.

Does the system comply with AFIR?

Yes. Our 120kW+ DC stations meet AFIR technical requirements for TEN-T network deployments, including CCS connector, ad-hoc payment, and OCPP roaming capability.

What is the lead time for a full hub system?

8-12 weeks from order to factory readiness. Site installation depends on civil works which are the customer responsibility or can be coordinated via our EPC partners.
