From cell to chassis — test the whole EV drivetrain

Traction motors, inverters, batteries, e-axles and complete powertrains — tested with real-time control down to 100 µs, native automotive protocols, and benches that scale from first prototype to end-of-line.

The challenge

e-Mobility test programs are outgrowing their labs

Faster platforms, shorter cycles

New motor and inverter generations arrive yearly. Test capability built for the last platform becomes the bottleneck for the next one.

Higher speeds, higher voltages

Modern traction motors spin to 30,000 rpm on 800 V systems — pushing older benches past their mechanical and electrical limits.

R&D and the production line diverge

Engineering benches and end-of-line testers are usually different vendors, different software, different data — and nothing transfers between them.

What we test

Every device in the electric drivetrain

Traction motors — performance, efficiency maps, temperature rise, regenerative braking, high-speed operation.
Inverters & motor controllers — validated under real load on real machines, with high-speed logging.
Batteries & BMS — pack and module characterisation, burn-in and endurance cycling.
e-Axles, reducers & hub motors — from coaxial reducers to heavy commercial drive axles.
Complete powertrains — three-in-one systems: performance, endurance, back-to-back and NVH.
ECUs — hardware-in-the-loop — LDRT real-time controllers running plant models against real ECUs over CAN FD, XCP and UDS.
Auxiliaries & heritage lines — suspension pumps, EMB brakes, starters and alternators.

The Langdi stack for automotive

One toolchain from prototype to production

The same software and controllers run your R&D bench, your HiL rig and your end-of-line testers — one data format, one skill set, no vendor patchwork.

LDRT — real-time & HiL

Control cycles down to 100 µs, built-in EtherCAT master, up to 16 CAN FD channels, one-click Simulink model deployment. About LDRT →

LDEV-X — test automation

Native CAN/CAN FD, XCP and UDS. Describe the test in natural language — the AI agent builds the sequence; log 1000 channels @ 1 kHz. About LDEV-X →

LD-LMS — the whole lab

Every motor cell, battery cycler and HiL rig on one web dashboard — scheduled, monitored, traceable. About LD-LMS →
