EV Maintenance & Battery Storage

Electrified fleets need service capacity and charging infrastructure that actually exists. We build both, plus the stationary storage that keeps demand charges down.

Capabilities

Service the electrified fleet — and store the energy that powers it.

Fleet-ready EV service, high-voltage diagnostics, and stationary battery installations. Everything from a single service bay to megawatt-hour BESS deployments.

HV diagnostics & repair

High-voltage troubleshooting, pack service, and safe isolation procedures.

Fleet electrification

Depot planning, charger installation, and service-bay buildout.

BESS design & install

Storage sized for peak shaving, backup, or renewable firming.

Second-life batteries

Programs that keep usable packs working instead of scrapped.

What you get

  • 01

    Less fleet downtime

  • 02

    Lower demand charges

  • 03

    Charging that keeps up with the fleet

Questions

Straight answers.

Do you service mixed fleets?

Yes — we support electrified and conventional vehicles during the transition period, which is where most fleets actually live.

How large a storage system can you install?

From single-cabinet commercial systems up to megawatt-hour deployments, including the electrical and civil work.
