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

Green Car Congress

The MSG can be run in island mode in parallel to the grid operated by the local energy provider. The MSG is designed as a direct current (DC) grid. We settled on a DC design for our micro smart grid to avoid the losses that occur when transforming alternating current (AC) into DC. — Dipl.-Ing

BYD’s home city in China now has more supercharging plugs than gas pumps

Baua Electric

billion to grow its EV business and undercut the competition with aggressively low pricing. And these “superchargers” aren’t just DC fast chargers – they can charge EVs to 80% in just 10 minutes. So, the city has to plan carefully so as not to overburden the grid as both EVs and superchargers rapidly come online.

OEMs shifting towards onboard chargers > 6 kW for EVs; lower output chargers to remain dominant through 2020

Green Car Congress

Manufacturers are developing bidirectional chargers that can interact with a power grid. Suppliers must, however, begin to manufacture DC-DC converters and PFCs themselves, as these components account for the maximum cost of onboard chargers and contribute to higher prices.

Why gas stations should add EV chargers?

Setec Powerr

With growing concerns about environmental friendliness and escalating natural gas prices, more and more consumers are looking for alternatives. EV chargers are divided into two key types: AC chargers and DC fast chargers. For example, using SETEC POWER’s 180kW fast charger , EVs can be charged from 0-80% in just 10 minutes.
