Powertrain & Battery
EV powertrain and battery pack engineering
The pack drives cost, weight, range, charge time and half the certification burden. We engineer it against the duty cycle your customers actually ride, not a competitor's spec sheet.
Sizing the pack on real duty cycles
Most EV programs over-specify their battery because the range target was set by marketing before engineering saw it. We build a duty-cycle model from real usage data, then size cells, capacity and power delivery against it — and show you what each extra kilometre of claimed range costs in weight, money and charge time.
That conversation usually happens once, early, and saves a program from carrying a pack it never needed.
Pack architecture, BMS and thermal
Cell selection, module layout, busbar and interconnect design, enclosure structure, venting and propagation strategy. We design packs that pass abuse testing and can still be assembled by real people on a real line.
BMS strategy covers cell balancing, state estimation, fault handling and diagnostics, specified alongside the thermal system so the two behave as one control problem rather than two argued ones.
Motor, inverter and charging
We select and integrate motors and inverters against the torque and efficiency map the vehicle needs, then develop the control calibration that makes it feel right to the rider. Charging work covers onboard and off-board topologies, connector standards for the target markets, and the safety interlocks certification will ask about.
