Bosch starts production of 800V inverter, motor for electric vehicles

Green Car Congress

Bosch is now starting the production of new powertrain solutions based on 800-volt technology. The 800-volt version of the inverter is based on silicon carbide semiconductors. In the 800-volt variant of the electric motor, Bosch has increased the power density. With 800 volts, twice this is possible in theory.

ZF presents EVbeat concept vehicle with prototype of new 800-volt electric drive; compact, lightweight and efficient

Green Car Congress

The EVSys800 used in the concept is a modular 800-volt drive and consists of SiC power electronics, the electric motor and a reduction gearbox. For cooling, ZF allows oil to flow directly around the copper rods exactly at the point where most heat is generated during operation. EVSys800 e-drive.

ZF develops compact, competitive magnet-free electric motor: In-Rotor Inductive-Excited Synchronous Motor

Green Car Congress

To ensure that the magnetic field in the rotor is built up by current instead of magnets, the conventional SESM concepts currently still require sliding or brush elements in most cases, which force compromises: A dry installation space, i.e. not accessible for oil cooling and with additional seals, is necessary.

“Project Volt Gas Volt” proposes long-term financing plan to support widespread implementation of power-to-gas systems

Green Car Congress

Project Volt Gas Volt is based on a long-term financing plan and the use of existing technologies for the large-scale conversion of surplus renewable electricity to methane, with subsequent reuse. If this potential production supplied the Volt Gas Volt plants, the nuclear plants could operate at nearly 100% capacity.

Porsche presents Mission R concept electric competition car

Green Car Congress

The power output remains constant over the duration of the race, so there is no thermally induced de-rating—a major advantage of the electric motors with direct oil cooling developed by Porsche. Highly efficient motors with direct oil cooling. High-end battery and 900-volt technology. Its total capacity is 82 kWh.

GM sourcing components for the Chevy Volt produced from recycled oil-soaked plastic booms from BP spill

Green Car Congress

General Motors has developed a method to convert an estimated 100 miles of the oil-laden plastic boom material used to soak up oil from the BP spill in the Gulf of Mexico earlier this year into parts for the Chevy Volt. Video of processing the boom material. Click to launch.

New Bosch 230 electric motor and inverter with silicon carbide technology offers system efficiency up to 97%

Green Car Congress

The new 230 electric motor has a rated voltage of 800 volts and is designed for long service life. To achieve this, hairpin winding technology is used in the stator as well as combined oil-water cooling. The rotor and stator are internally oil-cooled and the active parts are installed in a water cooling jacket.
