Porsche wit 12V lithium-ion rechargeable battery
Recently, the German Porsche (Porsche) that it has developed a lithium-ion battery with the 12V battery will be announced in January 2010 to begin Germany. The battery can with the car as “911 GT3″ feature “, toshiba PA3284U-1BRS battery，toshiba PA3285U-1BRS battery， toshiba PA3285U-2BRS battery911 GT3 RS” and “Boxster Spyder” 3 models.

The battery itself) at a price of 1904 euros (including VAT, in the purchase of new vehicles as an optional accessory options that we continue) to 2499 euro (inclusive of VAT.
Lithium-ion battery has a small light than the average amount of lead battery characteristics. Weighs less than 6 kg, compared with a capacity of 60Ah lead battery light 10kg. Size, the two types of cell length and width the same, but the lithium-ion rechargeable batteries, the lower height of 70mm. Sport Tourism (Sport Run) Lithium-ion rechargeable battery, if portability is a big advantage, but the lithium-ion battery to start the engine below 0 ℃, limited capacity, so in the daily use of the use of lead batteries. The location of the battery button, the circuit wiring, as well as the battery voltage range, and so on and lead the same, it can be easily replaced, you will lose no time.
A capacity of 60Ah Lead in the shape of the battery due to system error reasons, you can actually use the SOC (state of charge) in order to achieve the capacity of 30%. On the other hand,easy battery even if the capacity of lithium-ion battery only 18Ah, but almost fully utilized. Used to develop a lithium-ion batteries in the cathode material lithium iron phosphate, from 4 units and battery management system structure.
