GE's product called WattStation comes out in the summer. Sometime this year the 'Siemens Charge' is due.
The US government has put up $2.4 billion to develop an electric car industry and the China government has put up $15 billion.
Pike Research says the world market for chargers was only $69 million last year but will top $1 billion in a couple of years.
Incentivising electric car buyers are: GE's plans to install 35,000 WattStations in the US; a US government subsidy of $7,500 per car; a further Californian subsidy of $5,000 per car.
Disincentives are: electric cars cost twice the equivalent petrol car; take eight hours to charge and have limited speeds and ranges.
Electric car models available for sale include Th!nk City, Nissan Leaf, REVAi, Mitsubishi iMiEV, Buddy, and the Tesla Roadster.
