Bi-Directional Charger · EVBC

Charge the bus. Then let the bus power the site.

A 60 kW fast charger that also works in reverse. The same cabinet that fills a vehicle overnight can pull power back out when your site needs it: standard 60 kW in each direction, configurable up to 120 kW combined.

The problem

A parked fleet is a warehouse of energy nobody uses.

School buses work a few hours a day. The rest of the time, they're rows of very large batteries sitting in a yard. Until now, all that stored energy has had exactly one job: waiting.

How

One cabinet. Both directions.

Plug in a V2G-capable vehicle and the EVBC charges it like any fast charger. Reverse the flow, and the vehicle's battery feeds your site instead: 60 kW standard each way, configurable to 70/50 or 80/40 when discharge matters more than charge. The industry calls it vehicle-to-grid, V2G. We call it putting the battery you already bought to work.

What you get

Power both ways.

  • Backup power you already own

    When the site needs power, the fleet you already bought can supply it. The capability lives in the cabinet; how you use it is your energy strategy's call. And because modules replace without a complete system shutdown, your backup source doesn't go dark for maintenance.

  • Built for bus-yard reality

    Sealed cabinet, closed-loop thermal management, NEMA 3R, rated to −35 °C. It lives outside, next to the buses, year-round.

  • In service, not in theory

    Bi-directional school-bus charging is running today at a major student-transport operator. ◇

What's different

Compare it to the usual.

  • The way it usually goes: New service, new transformer, a years-long queue.

    With Pii: Any panel: single-phase, three-phase, or a DC bus. Patent-pending busbars switch inputs in minutes.

  • The way it usually goes: Hardware from far away, support from farther.

    With Pii: Engineered and assembled in American Fork, Utah. Watched 24/7 from Plano, Texas. BABA-compliant line for federally funded work.

  • The way it usually goes: Quoted lead times measured in quarters.

    With Pii: Stock ships in as little as 3 weeks. Modules swap in the field in minutes.

  • The way it usually goes: A catalog SKU or nothing.

    With Pii: White-label, custom ODM, or listed modules alone: an engineer on the line.
