New Battery Breaks Barrier For Electric Cars

New Battery Breaks Another Barrier In Electric Car Development

 Development of alternative fuelled cars is continuing to make steady
progress, with many manufacturers focussing on electric powered cars as a
medium term option. 

 Progress in development of electric power took a major leap forward
recently when a Mitsubishi FTO fitted with manganese lithium-ion batteries
covered 2,142 kilometres in 24 hours.

 The record distance was set at Mitsubishi Motors' car research and
development centre proving ground [in Japan, I believe; D.], where the
FTO-EV covered 899 laps of the 2.4 kilometre track at an average speed of
89.3 km/h.

 The newly developed manganese lithium-ion battery has faster charging and
greater cruising range per charge.

 Charging the batteries used to power an electric vehicle has traditionally
been a very lengthy process, restricting both the time a vehicle can
operate and the cruising range per charge. Previously vehicles have been
limited to about 150 kilometres a day.

 To try to overcome this, Mitsubishi researchers are placing their focus on
speeding up the charging time and extending the battery capacity per
charge. The new batteries have a capacity of 27 kWh and can be recharged in
20 minutes, compared with 55 minutes and 26 kWh for the nickel-hydrogen
batteries that have been a focus of research in the past. The maximum
charging current is 240 amps for the lithium-ion cell compared with 100
amps for the nickel-hydrogen battery. At 360 kg the lithium unit is also 80
kilograms lighter.

 Lithium-ion batteries are now being used in Mitsubishi's hybrid electric
vehicles which are also fitted with high economy GDI engines. These energy
systems switch back and forth constantly between expending power for
acceleration and storing power during braking to provide remarkable fuel
efficiency.
