FAQs

Quick answers to practical engineering questions about electric driven oil pump development, independent oil supply, hybrid operation, control strategy, validation, and compact e-powertrain integration.

An electric oil pump makes sense when oil supply must be independent of engine speed or mechanical drive, for example during engine-off phases, hybrid operation, start-stop, EV drive modes, or on-demand thermal management.

Yes. TPV can develop the pump concept around hydraulic targets, electric drive requirements, packaging limits, control strategy, voltage environment, operating points, and system-level oil demand.

In some applications, yes. The feasibility depends on flow demand, pressure targets, duty cycle, available electrical power, thermal requirements, packaging space, and safety or redundancy requirements.

Useful inputs include pressure and flow targets, duty cycle, oil temperature range, voltage environment, control strategy, installation space, hydraulic circuit layout, thermal demand, and NVH or pulsation limits.

Prototype systems can be tested for flow delivery, pressure stability, power consumption, pulsation, NVH behavior, leakage, response behavior, and operating-point performance before series preparation.

Ideally before the pump envelope, electrical interface, hydraulic circuit, and control strategy are frozen. Early involvement helps optimize efficiency, packaging, oil supply, NVH, and manufacturability.
