The History of Battery Electric Vehicles

December 31st, 2011

Battery Electric Vehicles or BEVs, predated the Internal Combustion Engine (ICE) vehicles. It was between 1832-1839 that Robert Anderson, a Scottish businessman, invented the first electric carriage and Professor Sibrandus Stratingh from the Netherlands designed the first small-scale electric car which was built by his assistant Christopher Becker in 1835.

The storage battery improved, firstly by Gaston Planté, a French physicist who invented the lead acid cell in 1859 and the first rechargeable battery. Then, in 1881, Camille Faure developed a more efficient and reliable battery which became so successful in the early electric cars. This discovery caused battery electric vehicles to flourish, with France and Great Britain being the first nations to support widespread development of electric vehicles.

Prior to 1900, battery electric vehicles held many speed and distance records, the most notable of which, was the breaking of the 100 km/h (60 mph) speed barrier. It was by Camille Jenatzy on April 29, 1899 in a rocket-shaped vehicle named Jamais Contente (Never Happy) which reached a top speed of 105.88 km/h (65.79 mph).

During the early 20th Century, battery electric vehicles outsold gasoline powered vehicles and were successfully sold as town cars to upper-class customers. Because of technological limitations, these cars were limited to a top speed of about 32 km/h (20 mph). The cars were marketed as “suitable vehicles for women drivers”. Electric vehicles did not need hand-cranking to start.

One of the downfalls of the battery electric vehicle was the introduction of the electric starter in 1913. It simplified the task of starting an internal combustion engine which was previously difficult and dangerous to start with the crank handle. Another was the mass-produced and relatively cheap Ford Model-T. Finally, the loss of Edisons direct current electric power transmission system. He was battling with George Westinghouse and Nikola Tesla over their desire to introduce alternating current as the principal electricity distribution. Edison’s direct current was the load for electric motors.

Battery electric vehicles were limited to niche applications. Forklift trucks were battery electric vehicles when introduced in 1923. BEV golf carts which were used as neighborhood electric vehicles and were partially “street legal”. By the late 1930s, the electric automobile industry had disappeared until the invention of the point contact transistor in 1947 which started a new era of electric vehicle.

In 1959 the Henney Kilowatt was introduced and was the world’s first modern transistor-regulated electric car and the predecessor to the more recent battery electric vehicles such as General Motors EV1. Only 47 Henney Kilowatts were produced, 24 being sold as 1959 models and 8 as 1960 models. It is not clear what happened to the other 15 built but it could be possible that they were sold as 1961 or 1962 models. None of the 8 1960 models were sold to the public because of the high manufacturing costs, but were sold to the electric cooperatives who funded the project.

It is estimated that there are between four and eight Henney Kilowatt battery electric vehicles still in existence with at least two of the survivors still driven periodically.

Battery electric vehicles have had issues with high battery costs, with limited travel distances, with charging time and the lifespan of the battery, although advancements in battery technology has addressed many of those problems.

At the present time, controversy reigns over battery electric vehicles. Campaigners, (et al) for BEV’s are accusing three major US automobile manufacturers of deliberately sabotaging BEV efforts through several methods, for instance, failing to market, failing to produce appropriate vehicles, by failing to satisfy demand and using lease-only programs with prohibitions against end of lease purchase.

In their defense, the three major manufacturers they have responded that they only make what the public want and the current trend is that the public doesn’t want battery electric vehicles.

Although we have the technology to manufacture and provide BEVs, one of the biggest downfalls for the prolific production of BEVs is the extortionate cost of replacement batteries. In some cases the cost of replacement batteries can be more than the price of the whole vehicle, especially when buying used battery electric vehicles.

The Future As Represented By 5 Exciting Concept Cars

December 31st, 2011

The latest ideas in car design are embodied in concept cars which give the manufacturers the opportunity of judging the public’s response to them. There’s bound to be something that will appeal to all of us whether the concept is technical innovation or design. For 2011 I present five cool concept cars.

The likelihood of having your new car written off is fairly strong, it’s best to take out gap insurance when you purchasing the new car.

Volkswagen XL1 Concept

First unveiled at the Qatar Motor Show the Volkswagen XL1 Concept puts the emphasis on economy. The car is not heavy on account of its strong yet light carbon fibre body. A 20kw lithium-ion battery pack will take the XL1 twenty miles at which point a 800cc 48hp engine takes over. A further efficient 320 miles can be squeezed out of the small 2.64 gallon fuel tank. It’s a mystery as to how Volkswagen will manage to provide production models of this concept at a reasonable price.

Renault Captur concept

Renault hope that the new Captur concept car will sell like hot cakes. With its removable hardtop and its eclectic features the Captur combines the characteristics of a convertible, an MPV, a coupe and a hatchback. Anyone sitting in the Captur will experience a strange floating feeling which is the result of having the seating attached to the central console rather than to the floor. Powered by a 158bhp engine, it is capable of speeds up to 130mph. Low emissions put this concept in the tax free range.

BMW Vision ConnectedDrive

At the 2011 Geneva Motor Show this sleek and aggressive looking concept car has stimulated enormous interest. The bodywork is beautifully designed with rounded headlights and grill that is reminiscent of a shark’s head. Sliding doors remind us of the Z1 limited edition and the L shaped rear light cluster is a new design we’ll be seeing on new Beemers. Essential information such as speed is displayed on a 3D screen which can also display GPS information when needed.

Infiniti Etherea concept

Infiniti’s contribution to the Geneva Motor Show is the Etherea, their first compact car and a direct competitor to BMW’s Series 1. The Etherea, a smart hatchback, is quite different from Infiniti’s usual range of luxury 4×4′s and executive saloons. Probably to be powered by a turbocharged 4 cylinder Mercedes Benz engine, this petro-electric hybrid will be in production in 2014 and is clearly aimed at a younger market. My wish list includes the Etherea and the necessary gap insurance.

Vauxhall Zafira Tourer concept

Amazing performance is not a pre-requisite of a concept car. The Zafira Tourer, by Vauxhall, is an example. The hugely popular MPV could be superseded by this seven-seater passenger vehicle. Although shown as a concept, the style and design may be what we will see when it goes into production later this year.

The Zafira features a new version of the Flex 7′s practical seating system but does not inherit the FlexDoor system from the Meriva. On the dash there’s a touch screen display whilst the rear seat passengers can surf the internet or watch films on the front seat mounted laptops.
