Volkswagen demonstrates e-Golf that can park (and charge) itself
This week’s Consumer Electronics Show in Las Vegas features a fleet of vehicles from Volkswagen that showcase the triple trends of electrification, autonomy and connectivity. VW notes that its plug-in models, the e-Golf and Golf GTE, would be inconceivable without computers that control such functions as battery charging and switching between gas and electric drive… Read more »
Navy develops electric gun powered by K2’s Li-ion batteries
It’s not just cars that are getting electrified – guns may be going high-tech as well. The Office of Naval Research (ONR) has ordered a battery system from K2 Energy Solutions to be used in an electromagnetic rail gun, part of an $81,400,000 contract. Rail gun technology uses electromagnetic energy instead of chemical propellants. A… Read more »
PG&E and BMW team up to test V2G services
Pacific Gas and Electric Company (PG&E) and BMW are working together to test the ability of EV batteries to provide services to the electrical grid. PG&E selected BMW after a competitive solicitation to manage a minimum of 100 kilowatts of electric demand on PG&E’s system, as other large industrial and commercial customers do today as… Read more »
Car Charging Group raises $6 million in new funding
Car Charging Group, the Florida-based provider of EV charging services, has closed an offering of convertible preferred securities and warrants, and raised net proceeds of up to $6 million from current institutional shareholders. Two million of the funds were delivered at closing, with the remainder to be disbursed upon achievement of operating milestones over the… Read more »
Siemens and Duke Energy demonstrate smart-grid-capable EVSE
As gains in energy efficiency and the plummeting cost of home-generated solar power threaten to shrink their revenues, some electric utilities seem to see EVs as a source of future demand for centrally-generated power. A case in point is Duke Energy, which, while leading the charge against efficiency and solar in its Florida service area,… Read more »
Blink charging stations to be restored to 30-Amp capacity
Florida-based CarCharging, which inherited the Blink public charging network from bankrupt ECOtality, has announced plans to upgrade its chargers, restoring the amperage from 24 Amps to its maximum capacity of 30 Amps. About two years ago, users began to report of problems with Blink level 2 charging stations at power levels above 3.3 kW. ECOtality… Read more »
ClipperCreek and Itron test EV chargers with virtual smart meters
In the charged world of the future, EVs will take energy from the grid when needed, and return energy to the grid when needed. This will require utilities to have a dependable way to measure the back-and-forth flow of electrons, so they can charge (or pay) their customers appropriately. In the industry, this is known… Read more »
How to avoid electrical infrastructure upgrades when installing EVSE
With the falling prices, increasing sales and growing mass-market appeal of plug-in vehicles, more and more facility owners are contemplating EV charging amenities for employees, tenants and visitors. EV infrastructure could become a real competitive differentiator by attracting the desirable EV-driving population. In today’s competitive landscape, facility owners can no longer ignore the idea of… Read more »
Simulation of battery pack cooling systems: measure twice, cut once
The experts at Mentor Graphics walk us through the simulation and analysis of a battery pack cooling system. In the business of battery pack design, one of the main considerations is cooling. The pack must have a uniform and stable temperature for the batteries to perform adequately during worst-case conditions. Even within a single cell,… Read more »
