Researchers developing DC micro smart grid for charging EV fleets; Li-ion, redox flow batteries and renewables

Green Car Congress

Up to 30 electric vehicles at a time can recharge in Fraunhofer IAO’s parking garage. The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. A 30-meter-tall wind turbine delivers 10 kW. Click to enlarge. — Dipl.-Ing

Mitsubishi Heavy to supply 500 kWh (normal) containerized Li-ion energy storage system to power grid of Orkney Islands

Green Car Congress

(MHI), jointly with SSE plc (formerly Scottish and Southern Energy plc), will begin an energy storage system demonstration project using the power grid in the UK’s Orkney Islands, which has a high proportion of renewable energy generation in relation to demand. The energy storage system will be installed at SHEPD’s Kirkwall Power Station.

Volkswagen introduces near-series design study of the MEB-based flexible quick charging station at Geneva

Green Car Congress

Connected to the grid or even off-grid, the station can charge up to four electric cars simultaneously, based on the principle of a ‘power bank’, two with DC quick charging. The charging station can be used as interim storage for eco-power; however, when connected to the mains power grid, it becomes a permanent charging point.

Mitsubishi Heavy develops containerized large-scale Li-ion energy storage system

Green Car Congress

Japan’s first container-type large-capacity energy storage system using lithium-ion rechargeable batteries. Power conditioners are used for direct current (DC)/alternating current (AC) conversion and their input/output control. Click to enlarge. Each container unit can be moved by container trailers.

PHEVLERs are the Zero CO2 Clean Green Machines of the Future

Green Car Congress

On the other hand, drivers of other vehicles waste considerable time making special trips to refuel their internal combustion engine (ICE) vehicles at the liquid fuel station or their battery electric vehicle (BEV) at the rapid recharging station. Slow Level 1 charging [ 11 ] should be used to recharge PHEVLER batteries whenever possible.
