Super-Fast Charging Batteries from Japan




Japan takes a big leap into making the world of transport cleaner, less fuel-powered and more environmental-friendly.  With the help from Japan’s National Institute of Advanced Industrial Science and Technology, Kawasaki Heavy Industries has announced the production of a battery that charges in matters of minutes, 10, to be more exact.

Coming after a development of an earlier version, the new nickel-hydrogen battery will greatly surpass it’s predecessor, taking not more 600 seconds to fully recharge.  If nowadays  lithium-ion batteries are more popular because of their small size and high-voltage operation capability,  the prices still are very high due to their building complexity.  Nickel-hydrogen battery, on the other hand, are far more cheaper and don’t contain flammable substances. The only disadvantage is their size, but still suitable for trains and buses. If equipped with the battery, the vehicles would not need another power supply, the accumulator only needing to be quickly charged during stops.

After the companies officials, the battery should be able to withstand 1000 charges before it stops providing power. Even if it is just a prototype, we can aspect to see them in function by 2013.

The picture above depicts a low-floor battery-powered light rail vehicle (LRV), called Swimo. It was build by Kawasaki Heavy Industries, in 2007 and uses a nickel metal-hydride battery.
