New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

The results could make possible a whole family of inexpensive and durable materials practical for large-scale rechargeable batteries. The use of the new type of membrane can be applied to a wide variety of molten-electrode battery chemistries, Sadoway said, and opens up new avenues for battery design.

The Essential Guide to EV Smart Charging and Smart Energy Management

Driivz

Smart EV charging uses intelligence to manage when and how an electric vehicle plugged into a smart charger will receive power for charging based on the cost of electricity, its availability, and the needs of the driver. They want chargers to always be available and simple to use. What is the Flexibility Market for Energy?

Greenlings: Benefits of charging stations vs. battery swaps vs. home charging

Tony Karrer Delicious EVdriven

Of course, everything has its drawbacks and one problem with charging at home is that it is not an option available for some city dwellers. Although charging infrastructure is beginning to find its way into cities, it may be awhile until they are available in residential neighborhoods en masse. It does not reflect well upon you.

I would say that electricity is a vastly superior fuel for the light vehicle fleet,” said Willett Kempton , a professor and alternative energy specialist at the University of Delaware. Battery recharging would typically take two to four hours, he said. And who is going to pay for all this???… — paul 8.
