Could new regulations hold back EV charging development?

While regulators and the charging industry are hashing out the details of new regulations, some are concerned that well-intentioned policies could have negative effects. The availability of EV charging infrastructure is increasing every day, and action by federal, state and local governments has been a major driver of this growth. However, like anything in life,… 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 »

California proposes DC metering standards for fast chargers, companies ask for more time

There is a proposal on the table in California that has to do with setting standards for energy metering on DC fast charging stations. Basically, the state is looking to enact regulations on EV charging similar to those that already exist for gasoline sales – gas pumps are regularly certified to ensure that when you… Read more »

LORD and Scheugenpflug collaborate to scale up EV thermal designs

When EV manufacturers find a high-quality gap filler that maximizes battery performance, they don’t want to hit a snag with the application system. One of the fundamental challenges in designing an EV battery pack is the effective management of heat generated during the battery’s charge and discharge cycles. A basic principle of physics is that… Read more »

ELANTAS increases electric motor longevity with nanoparticle-infused insulation

Protecting against dielectric fatigue Like the engines in conventional vehicles, the electric motors in EVs are designed for longevity, but every device will wear out eventually. While motors have many fewer moving parts than ICEs, they are under considerable electrical and mechanical stress. A properly designed electric motor should have a useful life that far… Read more »

2019 Subaru Crosstrek Hybrid review: Subaru’s first PHEV offers its loyal customers a taste of zero-emission miles

Any new plug-in vehicle from a maker that hasn’t previously offered one is cause for excitement, even if volumes are low at first. So I approached my six-day test of the new plug-in Subaru Crosstrek Hybrid with anticipation. Sure, its rated 17-mile electric range is below the curve, but at least it’s a start –… Read more »

A closer look at the losses in EV motors

  In the bad old days when the only batteries suitable for traction applications were flooded lead-acid and Ni-Cd types, the battery was the least efficient component of an EV powertrain, routinely delivering back only 50-70% of the amp-hours that went into charging it (aka the Coulometric efficiency). When you knew you were going to… Read more »

Muir Commons: A case study in MUD EV infrastructure

One of the thorniest problems with the transition to EVs is how to provide charging infrastructure for residents of multi-unit dwellings. In California, the world’s laboratory of electromobility, at least one electric utility is offering an incentive program to help owners of MUDs get charging stations set up for their tenants. Pacific Gas and Electric… Read more »

Koben Systems’ smart breaker panel and battery pack enable large EV charging installations

As the adoption of EVs continues to ramp up, condo complexes and workplaces will need to provide their denizens with adequate EV charging infrastructure. However, this is easier said than done. A few chargers can be added without surpassing the power available to the building, but as more EVs join the fray, and battery sizes… Read more »
