Maximum Efficiency for the Future of Electric Mobility

In the era of industrial and automotive electrification, the need for efficient and intelligent hydraulic systems has become a top priority. Parker Hannifin, the global leader in motion and control technologies, introduces Electro-Hydraulic Pumps (EHPs) as an integrated solution for electric vehicles (EV) and hybrid electric vehicles (HEV).

The EHP system is more than just a standard pump; it is a self-contained power unit that combines an electric motor, a drive (inverter), and a hydraulic pump into one compact package.

Key Features and Technical Advantages

The Parker EHP system is engineered to optimize energy consumption without compromising performance. Here is why the EHP is becoming the new industry standard:

• High Energy Efficiency: Unlike traditional engine-driven systems that rotate continuously, the EHP only operates when needed (Power-on-Demand). This significantly extends battery life in electric vehicles.
• Integrated Design (Plug-and-Play): Eliminates the need for complex hosing and separate component installation. The integration of the GVM (Global Vehicle Motor) and a high-power inverter ensures rapid installation.
• Noise Reduction: Ideal for vehicles operating in urban areas or noise-sensitive environments, as electric motors are much quieter than internal combustion engines.
• Smart Communication: Equipped with CAN bus protocols (J1939 or CANopen), enabling real-time diagnostic monitoring and precision control.

EHP System Components

This system is built upon three core pillars of proven Parker technology:

1. Hydraulic Pump: Utilizes high-performance Gear Pump or Vane Pump technology capable of handling consistent system pressures.
2. Electric Motor (GVM Series): A Permanent Magnet AC (PMAC) synchronous motor offering the highest power density in its class.
3. Mobile Inverter (GVI Series): A rugged drive with automotive certification to precisely regulate motor speed and torque.

Applications

• Public Transportation: Power steering systems for electric buses and trucks.
• Construction Equipment: Battery-powered mini-excavators, loaders, and dumpers.
• Material Handling: Large-capacity electric forklifts and reach stackers.
• Municipal Services: Electric refuse trucks requiring hydraulic power for lifting mechanisms.
