Volvo Fast Charger

Volvo, who are currently testing a several-hundred strong fleet of C30 Electric, has announced it is also testing a a 22 kW fast charger for said car.  This new on-board charger accepts three-phase AC at up to 32A which can provide an 80 km range in half an hour, a full charge taking just an hour-and-a-half (90 minutes).  As Volvo point out in their press release this is some five times faster than a normal 230V AC outlet (which would take eight hours for a standard full charge).  Fast charging is one of the big hurdles (along with public charging) which need to be overcome before EV cars can go mainstream.

J1772 AC/DC combo

In May this year several US and German car manufacturers agreed an extension to the J1772 charging standard providing both AC and DC charging using the same connector, a revised J1772 connector with two large additional DC pins below the existing AC / signal line connector.  This new design has now been ratified as a standard by the Society of Automobile Engineers (SAE) and may now begin to appear in both vehicles and chargers (likely in 2013).  DC charging provides for up to 500 V with a maximum current of 200 A (up to 100 kW), or around 20 minutes for a full charge.

Ecotricity Network

Just over a year ago Ecotricity announced its UK nationwide fast charging network, since then it has rolled out a total of ten charging locations at motorway service stations (highway rest stops) around the UK.  Today it's beginning the roll-out of DC fast chargers, initally in three locations; South Mimms (M25/A1), Oxford (M40) and Hopwood Park (M42).  These DC fast chargers can deliver 70A at 440V meaning a full charge will take just 30 minutes and a 'top-up' from 20-30% to 100% takes just 10 - 15 minutes.  All you need to use the charger is a free swipe card from the Ecotricity website, the use of the chargers is completely free.

J1772 DC combo

Last year we reported that the European Automobile Manufacturers Association (ACEA) were proposing a combined AC/DC EV charging connector and standard.  That appears to have come to fruition at the Electric Vehicle Symposium with the new SAE standard AC/DC connector and charging standard which promises charge times as short as 20 minutes (high power DC).  This new standard has been agreed by the big German and US car makers (Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen) but leaves them at odds with Nissan and Toyota who have both championed (and utilized) the Japanese CHAdeMO DC charging standard (typically 50-60 kW output).  This new standard enables charging up to 500 V with a maximum current of 200 A (up to 100 kW), connectors should appear on cars in 2013.

Acea Charging ProposalThe European Automobile Manufacturers' Association (ACEA) whose members include BMW, Fiat, Ford, GM, Porsche, PSA, Renault, VW and Volvo have published a 'position paper' on EV charging standardization.  This new document outlines a two phase approach, the first phase represents the current design of connector and state of charging, phase two introduces a new 'type 2' connector and is proposed to become the standard from 2017 onwards.  The type 2 standard enables AC fast charging up to 43 kW and DC charing above 43 kW.

ECOtality Dallas

ECOtality has begun the rollout of its charging network in Dallas.  The first two Blink pedestal charging stations installed in a (slightly unglamorous looking) parking lot in Deep Ellum mark the beginning of a network which will eventually include 200 charging stations across the city. “Plug-In Texas commends ECOtality, an important member of our coalition, for further advancing the public charging infrastructure in North Texas with The EV Project,” said Russ Keene, President of Plug-In Texas. “Electric vehicles are a positive progression for the Dallas-Fort Worth metroplex – these exciting, clean vehicles will make vehicle ownership more affordable and make a significant contribution to emission reductions, transforming transportation for Texas.” More »

SAE J1772

The SAE J1772 charging connector has become the de facto standard among many EV manufacturers including GM, Ford, Honda, Nissan and Toyota (and upcoming on the Model S also by Tesla).  The Society of Automative Engineers (SAE) are proposing a new 'combo' standard which will extend the current charging capability of the J1772 connector to support both higher charging rates as well as charger / grid to vehicle communication.  The new standard is designed to be backward compatible with basic single-phase AC charging at various currents (from as low as 15 amps) all the way through to fast DC charging at 200 amps (200 - 450 volts; 90 kW).  The IEEE will provide the own PLC (Power Line Communication) protocol which will allow the vehicle to commicate directly over the existing connection pins (similar to HomePlug).  SAE estimate the standard will be approved and released in early 2012.

SolarCity installation

SolarCity are now offering solar powered electric vehicle charging options to consumers (rather than their previously commercial-only solutions).  The new packages include leasing a solar panel system (cost varies depending on the install size) and the purchase of a ClipperCreek 240V Level II charger ($1,500).  According to their press release "Powering an EV with electricity generated from a home solar system can be 77 percent less expensive than powering a car with gas. An average San Francisco Bay Area resident paying the national average of $3.65 per gallon gas spends about $230 per month to fuel her gas-powered car. She’d pay $107 to power an equivalent-size EV with grid electricity, and, by leasing a solar system from SolarCity, only $54 to power the car with solar electricity for the same miles driven."  Sounds like the perfect way to deflect those "but electricity generation creates emissions" arguments (which ignore the well-to-wheel emissions for internal combusion engines).

Coulomb Technologies CT2025Coulomb Technologies has revealed two new dual port charging stations designed for use in public locations (hence the CharePoint integration) which can deliver 7.2 kW (240V @ 30A) to both ports SAE J1772 connected ports.  Over the CT2021 the CT2025 adds a photosensor activated 25W LED courtesy light and a retracting cord management system. “With the success of the Nissan LEAF and Chevrolet Volt, the demand for Level II EV charging in public and at workplaces is rising rapidly,” said Pat Romano, president and CEO of Coulomb Technologies.  “We are responding to the sharp rise in demand from our customers by providing more price and installation efficient dual chargers that can provide services for two vehicles in the same footprint that previously was required for one.  We are proud to introduce this new ChargePoint product family that continues our practice of innovation and market leadership.” More »

Ecotricity Electric HighwayMotorway service station operator Welcome Break has teamed up with Dale Vince's Ecotricity (he of Zero Carbonista and The Nemesis electric sports car) to provide charging points at Welcome Break service stations.  By September this year the target is to have charging points at 12 service stations and expanding that to all 27 Welcome Break service stations by Q1 2013.  Charging at both 32A and 13A will be available, the former perfect for a quick top-up while you have a break and a bite to eat.  Rod McKie, CEO of Welcome Break, said:  “We are very excited about working with Ecotricity.  There is no doubt that the electric car will arrive on Britain's motorways and Welcome Break wants to be at the forefront of giving the modern motorist what they want, when they want it.  As hybrid and electric cars become part of everyday life, Welcome Break will have the facility to fast-charge these cars, giving electric car drivers the opportunity to travel the length and breadth of the UK."
