Canada’s Brampton Transit buys 8 electric buses and 4 charging stations
Natural Resources Canada (NRCan) has granted Brampton Transit and Canadian Urban Transit Research and Innovation Consortium (CUTRIC) $11.15 million in federal funding. Brampton Transit, which serves part of the greater Toronto area, will use the funds to purchase eight electric buses and four OppCharge-compliant overhead charging systems. Six of the electric buses will be New… Read more »
Pre-Switch promises to add 5-12% more EV range by eliminating switching losses
How would you like it if your EV could go ten percent farther with the same size battery? You’d love it, of course, and so would every EV manufacturer out there. Range is one of the most important parameters in the EV industry, as many potential EV drivers are apprehensive about lower range ratings. Manufacturers… Read more »
Four automakers make a deal with California on fuel efficiency
In a setback for the Trump administration’s campaign of sweeping away environmental regulations, four automakers have forged a deal with California that imposes only a moderate relaxation of the Obama-era federal fuel economy standards, rather than the radical rollback requested by the Republican regime. Regular Charged readers will be familiar with the story so far:… Read more »
Electric marine propulsion system can save $1.7 million in fuel costs annually
An independent study for ABB by marine consultancy Deltamarin has found that the ABB Azipod electric propulsion system for ferries could save up to $1.7 million in annual fuel costs per vessel. By simulating a transit on seven existing ferry routes, researchers found that a ferry equipped with twin 10 MW mid-power range Azipod units… Read more »
Scaling EV charging infrastructure: Standards and interoperability
Sponsored by ABB. Download a PDF version of this article. A steeper growth curve for electric vehicles will depend on continuous technological development, further commercialization and practical regulatory policies. Standards and interoperability underscore all of these trends, across vehicles, charging systems and communication networks – and are a key driving force for electric vehicle adoption…. Read more »
The EV industry sees problems with California’s proposal to mandate credit card readers for public chargers
In California, there is a controversial plan to require credit card readers on all public charging stations, including retrofitting already installed units. California’s Electric Vehicle Charging Stations Open Access Act (Senate Bill 454, which passed in 2013) mandates open access to public charging stations – that is, a driver doesn’t have to be a member… Read more »
Determining ENERGY STAR specifications for high-power EV fast chargers proves challenging
The US EPA is proposing a new ENERGY STAR specification, Electric Vehicle Supply Equipment Version 1.1, which adds DC fast chargers to the existing specification. The process of proposing the spec and considering stakeholder comments began in early 2018, and is ongoing. The EPA is proposing to release a Version 1.1 Draft 1 Specification in… Read more »
