MegaWatts Autonomous
Hundreds of DC ports for robotaxi depots, without the wait.
24/7 autonomous depots need relocatable power now and a hands-free charging path later. We deliver both.

MegaWatts Autonomous supplies relocatable megawatt power and hundreds of DC ports for robotaxi and autonomous vehicle depots. Blocks of 700 kW to 1 MW+ feed 150 kW ports with dynamic power sharing, run under 24/7 network operations, integrate over OCPP 2.0.1, and are laid out for attendant plug-in today with a wireless or robotic upgrade path.
The autonomous problem
The fleet runs 24/7. The vehicles cannot plug themselves in. The depot lease forbids trenching.
Robotaxi depots need hundreds of ports, staggered around the clock, in real estate the operator does not own for long. Permanent switchgear is the wrong answer for a depot that may move in 18 months.

FAQ
Autonomous questions, answered.
Can the vehicles plug themselves in?
Not yet. Robotaxis rely on depot staff or automation for charging. We design port layouts for fast attendant plug-in today, with a wireless or robotic upgrade path when the fleet is ready.
How many ports can one depot get?
A 700 kW block feeds about 40 ports at 150 kW with power sharing; a 1 MW+ block feeds more. Depots with hundreds of vehicles stack blocks. Founder to confirm ports per block.
What about depot leases that forbid electrical work?
Mobile blocks sit on the pad and connect at the dispenser. No trenching, no switchgear inside the building.
How do you integrate with our fleet software?
OCPP 2.0.1 for charger control and telemetry, ISO 15118 for Plug & Charge, and a REST feed from the NOC for session data.
What term do you require?
Term length is set in your quote, from a short pilot to a multi-year agreement. Blocks relocate if the depot moves.
How fast is the response if a port fails?
24 hours or less to respond, with the SLA replacement target and credits. Depots at this scale get a named escalation contact.
