Tesla Supercharger Stations Unveiled In California

Posted on by

Tesla Motor’s highly anticipated charging network has finally been unveiled to the public with the revelation of it first six supercharger stations. According to Tesla, the stations will safely deliver up to 4.5 times more electricity to the battery giving approximately half a charge in half an hour. It will do this by using special cables that connect directly to the battery, bypassing any on board charging equipment. The most unique thing about these charging stations is that many will be equipped with solar cells mounted on the weather canopy that will generate more energy over the course of a year than is consumed by Tesla vehicles using the supercharger stations, resulting in a positive transfer of power back to the electricity grid. Current active stations in California can be found in Barstow, Hawthorne, Lebec, Coalinga, Gilroy and Folsom. By 2015, Tesla hopes to expand their supercharger network to over 100 stations.

Fisker Automotive is alerting drivers of certain 2012 Fisker Karma vehicles, built between June 15, 2011 to July 9,2012, about an electrical problem in the low temperature cooling fan. According to Fisker, a short in the fan could ignite the fan housing, shroud and surrounding components, causing a vehicle fire. Owners will be asked to bring in their vehicles to the nearest Fisker dealership to replace both low temperature cooling fans with improved fans. Owners wanting more information about the problem can contact Fisker consumer affairs at 1-855-575-7577, option 2.

Ford Invests In Hybrid And Electric Technology

Ford is working hard to become the leader in hybrid and electric vehicles (EV) as they invest over $130 million to build an advanced electrification center in Dearborn, Michigan. The facility will employ approximately 1,000 engineers and will accelerate the companies EV development capabilities. The company hopes to top the market by launching five new electric or hybrid vehicles this year alone. Ford has just recently started developing their own transmission technology which will be built on the same platform as their mainstream gasoline engines. This has allowed them to cut the costs by 30% and will also allow the company to build vehicles according to consumer demand. Amy Machesney, the C-Max marketing manager said Ford feels it now has a product capable of competing with Toyota, and we are confident our EV and hybrid vehicles are comparable to the Prius.

Mitsubishi Airbag Sensor Problem

Mitsubishi is asking owners of certain 2012 i-MEV electric vehicles to bring in their cars to correct a problem that could prevent their airbags from deploying properly. According to Mitsubishi, an incompatibility between the air bag sensor and the self diagnostic software, could deactivate the front and side airbag system. During an accident, the airbags may fail to deploy, increasing the chance of injury. Owners of affected vehicles may notice the Supplemental Restraint System (SRS) warning lamp illuminating to alert the driver of the problem. Owners wanting more information can contact Mitsubishi at 1-800-222-0037.

A123 Systems Sale Raises Security Concerns

Posted on by

The potential sale of U.S. automotive battery maker A123 Systems to China’s largest auto components company, Wanxiang Group Corp., is raising security concerns among U.S. lawmakers. The $450 million deal would see Wanxiang taking control of 80% of A123 Systems which supplies lithium-ion batteries to luxury car makers like Fisker Automotive. A123 received funds from the Energy Department in 2009 which was used for battery research advancements and job creation programs for batteries used in hybrid and electric vehicles.

Opposition to the sale reports growing concern about foreign controlled or owned companies gaining a niche in the United States supply chain. According to U.S. Rep. Cliff Stearns, “We need to make sure the Federal government isn’t giving away our own national secrets by providing Chinese automobile manufacturing companies with million dollar government grants and loans.” Under the terms of the grant, the company agreed to use funding to support U.S. manufacturing facilities. Changes to the agreement of the grant would first have to be approved by the Department of Energy (DOE) who does not approve grant money being used for anything other than investment in the manufacturing and job creation here in the United States.

Low Gas Tax Revenue Prompts New System

Posted on by

Counties in the San Francisco Bay area are considering getting rid of gas taxes and switching to a vehicle miles traveled (VMT) system instead. The National Surface Transportation Infrastructure Financing Commission (NSTIFC) recommends the switch because revenue from gas taxes have declined over the years as hybrid, electric, and more fuel efficient vehicles become prevalent on roads. They say that it will “balance the costs and benefits of the surface transportation system to those who are using it”, and could also reduce traffic congestion on the roads. The proposal is one idea in long range planning, updated by the agency every four years. If the idea is accepted, it would likely not be fully imposed until 2020.

Randy Rentschler, a spokesman for the regional commission, admits that the idea could be difficult to introduce. Radical changes like this will always be opposed by certain groups, and privacy issues will be questioned as a GPS based systems would be used to log information on when and where drivers are traveling. Transit advocacy groups are encouraging the transition to a VMT system to be tested first in the Bay area where the idea will be more easily accepted and the revenue could be used to support alternative public transportation options.

Powering EVs With Lithium-Air Batteries

Posted on by

Consumers who are thinking of purchasing an electric car are usually deterred by the range of the lithium-ion battery used as the power source. Concerns about range, life expectancy, and the ability to find a charging station usually results in the consumer purchasing the vehicle with the technology they are familiar with, the combustion engine. Researchers are hoping to change consumers attitude toward electric vehicles with a new electrochemical cell called the lithium-air battery.

Lithium-air batteries are attractive to researchers because they rely on air as the cathode and lithium metal as the anode. This allows the battery to be lighter and can offer up to ten times more energy per density mass unit than conventional lithium-ion batteries. The first lithium-air battery was developed in the mid 1990’s but the technology still requires improvements before we can expect to see it used commercially.

  • The battery requires a steady flow of oxygen to operate, so an air compressor and blower will need to be added to the system. This not only negates the weight reduced on the battery, but adds extra parts to the system.
  • Lithium metal is highly flammable when exposed to water, so water vapor must be removed from the air and a water tight encasing is required.

Despite recent significant improvements in the technology, researchers say we are still 15 to 20 years from seeing it offered to the public. Once the battery has been approved a long term array of testing is required to make sure the battery can be used safely.
