Build an EV system you can trust

Renco helps manufacturers design and validate EV systems that behave predictably under real operating conditions.

Built on more than a decade of EV system engineering, we support programs from early development through series vehicles, with a system-first approach grounded in integration, control, and verification and validation.

Let’s talk about your system plan

This experience is what shapes how we work today.

Since 2009, the team behind Renco has been designing, integrating, and validating electric vehicle systems across demanding environments.

High-performance racing. Commercial and industrial vehicles. Specialty platforms and complex EV programs.

System behavior is the real challenge

Electrification doesn’t fail because teams pick the wrong component. It fails when propulsion, controls, safety, and suppliers aren’t aligned as one system. When the system is designed and validated early, teams move faster with fewer surprises.

Clear interfaces and responsibilities

Earlier proof of system behavior through verification and validation

Lower technical and financial risk

Platforms that scale with less rework

How it works

System-first engineering. Proof-first delivery.

We work like a systems partner, not a component broker. Our focus is on making the full EV system behave correctly before it reaches the field.

This is how predictability is built into the system.

Define the system reality
01
Understand the vehicle, duty cycle, constraints, and success criteria.
Design the complete EV system
02
Architecture, propulsion, controls, auxiliaries, and interfaces treated as one.
Verify and validate early
03
Software and system behavior tested and refined before vehicle operation, then confirmed through vehicle validation and calibration.
Built on 15 years of EV engineering
Solutions

Proven execution when it matters most

High-voltage architecture designed for the specific machine

Proven propulsion and subsystem combinations

Reusable control software validated before vehicle power-up

A faster, lower-risk path to a working electric vehicle in the field

How we support the system

Everything we do serves one outcome: predictable system behavior.

System Engineering
01
Align requirements, controls, interfaces, and responsibilities from the start.
software development
02
From our rapid quality management process to the rigor of ISO 26262 and hardening of ISO 21434.
Verification & validation
03
From fast model-in-the-loop (MIL) iterations to real hardware under real load conditions at our powertrain-in-the-loop (PIL) facility in Cologne.
Calibration
04
Simulation based development means less calibration time on the vehicle.
Advanced Engineering Services
Proof from real programs

System-first engineering and early validation show up in real delivery.

Talk to engineers who’ve been here before

If you’re responsible for an EV program and want to reduce uncertainty before it becomes risk, let’s talk.

We’ll review your system reality and outline a clear, feasible next step.
