MULTIPLICITY BUILDING RELIABLE SOLUTIONS
HEAVY-DUTY ONBOARD POWER

Power engineered around the mission.

Multiplicity designs, integrates, tests, and supports onboard power systems for cars, trucks, command vehicles, and specialty fleets. We start with what your equipment must do, then engineer the vehicle around real electrical loads, runtime, and charging strategies.

THE CUSTOMER STORY

Your team does not need a box of components. It needs a working vehicle.

01
THE MISSION

Tell us what must stay running.

We document electrical loads, duty cycles, operating times, and field failure risks before recommending equipment.

02
THE ENGINEERING

We build the complete architecture.

Storage, charging, power conversion, breaker protection, cooling, and service access are designed as one system.

03
THE OUTCOME

A vehicle your team can trust.

Integrated, load-tested, circuit-labeled, and fully documented for reliable long-term fleet operation.

PROJECT STARTER

COMMON QUESTIONS

Clear answers before starting your build.

How is an onboard power system sized?

We review your equipment specs, peak surge loads, required engine-off duration, chassis payload limits, and recharging conditions to engineer the right system.

Do these systems eliminate engine idling?

Yes. Automotive-grade lithium systems run auxiliary air conditioning, command IT, scene lights, and power tools without running the vehicle's engine.

Can Multiplicity retrofit an existing vehicle?

Yes. Retrofit feasibility depends on chassis condition, mounting space, and alternator compatibility. We conduct an audit before beginning.

Bring us the mission. We'll engineer the power system.
