New battery technology further advances the case of electric vehicles

French firm Bolloré has developed an innovative lithium metal polymer (LMP) battery. This is the result of a 15 year research and development process. Low levels of interest by OEMs in the new system encouraged Bolloré to launch its own electric vehicle featuring this battery. Called the Bluecar, the vehicle is now available in Paris through the autolib scheme. The aim of the project is to have 1,100 rental stations, 3,000 Bluecars and 6,600 charging stations in 47 areas in the great Paris area.

French firm 4887 Bollore has developed an innovative lithium metal polymer (LMP) battery. This is the result of a 15 year research and development process. Low levels of interest by OEMs in the new system encouraged Bolloré to launch its own electric vehicle featuring this battery. Called the Bluecar, the vehicle is now available in Paris through the autolib scheme. The aim of the project is to have 1,100 rental stations, 3,000 Bluecars and 6,600 charging stations in 47 areas in the great Paris area. In the first 100 days, 1,000 cars were introduced to the market, 11,000 customers have registered to the service, for a total of 60,000 rents.

Meanwhile new Japanese technology is promising journey distances of up to 351km on a single charge for electric vehicles. A second prototype developed at Keio University, called the SIM-WIL, can theoretically travel 351km on a single charge.
This calculation is based on the JC08 urban driving cycle for emission and fuel economy measurements of light-duty vehicles, introduced in Japan in 2011. It is an admittedly optimistic calculation that measures performance under ideal driving conditions, which are hardly achieved in real life. The JC08 calculates that a 2454 Nissan Leaf can travel 200km on a single charge, although in reality it is closer to 130km. Given this calculation, the range of the SIM-WIL on a single charge is reality likely to be slightly below 300km which is still impressive for a full-electric car. Performance is brisk and the SIM-WIL accelerates from 0-100km/h in 5.4 seconds. Traction is delivered by four in-wheel motors, with the battery and inverter integrated in the car frame. The name SIM-WIL is the development of the earlier SIM-Lei, which in April 2011 achieved 333km using a 24.5 kWh battery. The SIM-WIL features a stronger battery with 35.1 kWh. 34 companies and organisations have been involved in the development of the SIM-WIL, including 4888 Asahi Kasei Corporation, 4889 Carmate, 3405 Bosch, 2333 Takata, 4890 Tohoku Electric Power, 4891 Toppan and Mitsuuroko. SIM-Drive is continuing the work on prototypes with the objective to start commercial production in 2014.

  • Questions are being asked about the success of electric cars
    June 21, 2012
    Electric car sales in many countries remain sluggish. In the US, Chevrolet’s Volt model sold 7.671 in 2011 while sales of Nissan’s Leaf model reached 9.674. Meanwhile sales of electric cars in the UK for example have topped around 2,100 units since 2006. Major barriers to public acceptance of pure electric cars remain the high prices, due in part to the costs of the batteries. Costing up to US$15,000, a lithium ion battery pack for a car is not a cheap option.

    The authorities in China are keen for increased use of electric vehicles as part of a plan to reduce pollution in major cities, and as part of a wider programme aimed at lowering the environmental impact from mobility. Fuel costs are comparatively high in China, further encouraging drivers to switch to electric vehicles, at least for urban trips. And electric-assist bicycles as well as scooters are already popular in Chinese cities, highlighting the strong potential market for electric cars in the country.

    Sales of electric and hybrid vehicles were up significantly in France in 2013 compared to 2012, reports Avere France. Electric utility vehicle sales were up 42% to 5,175 units, electric sales rose 50% year-on-year to 8,779 units, and there was a 60% rise in hybrid car sales to 46,785 units. In the latter segment, Toyota is still the leader with 27,536 vehicles sold thanks to the Yaris, Auris and Prius. In electric cars, the Zoé (Renault) is the leader with market share of around 63%, in front of the Leaf
