An electric vehicle buyer may have several worries when they plug their cars at home. One may be worried about power outages, circuits giving in, or someone simply disconnecting the plug and having no enough power to use the next day.

Charging anxiety is expected since we are facing a new technology but it is expected to die down like how people get accustomed to new gadgets, tools, or systems. Consumers are expected to have newbie questions when they initially charge their cars. Instruction manuals will be read and phone calls will be made just to make sure that they are plugging in their cars right.

Though there have also been studies about range anxiety as being the more important issue to address, car manufacturers and marketers can not deny that charge anxiety exists. Plugging the car into the socket may not come as easy as charging your cellphone.

Some experts see the comeback of gas station attendant which were icons during the early existence of refilling stations. This time attendants will assist consumers to plug and charge their electric cars. They see it this as a short-lived solution since people will eventually be able to adapt to the technology.

Different companies are trying to find ways and tools to help people decrease charge anxiety. Innovations may soon hit the market to help with the problem.

The Gigacell was developed in cooperation with New Energy and Industrial Technology Development Agency (NEDO) of Japan. It offers a big capacity in storing energy which is made responsible by its high-rate structure, discharge ability and high rate charge. It used nickel hydroxide as its positive electrode while utilizing the metal hydroxide for its negative electrode.

KHI is also designing a 280Ah stack with an enhanced charging and discharging rates. It has 2.5 kWh of aptitude and volumetric density of 40 Wh/L and 21 Wh/kg gravimetric density.

Last December 2007, KHI declared that it had completed a verification test using a Gigacell pack on a railcar regenerative braking. The system was analyzed at the substations of the Osaka Subway.

Kawasaki confirmed that the generated energy by the braking of a train could be accumulated and be reused to counterweigh for the voltage fluctuations that take place during start-up, operation, and jam-packed rush hours.

They also carried out test simulating operations during emergency situations like power outages and proved that the battery structure enabled trains to get to the next nearest station at a speed that is in the lower level without sacrificing needs for lighting or air conditioning.

Presently, Kawasaki has plant manufacturing prototype units with the capacity totalling 10,000 kWh. If they received adequate orders, KHI is planning to spend a billion for the production of Gigacell.
