Coinciding with the opening of the first BMW i Store on London’s Park Lane, the BMW Group presented the new BMW i Pedelec (Pedal Electric Cycle) Concept—a custom-made complement to the BMW i3 Concept ( earlier post ). The compact bicycle can be folded up quickly; the trunk of the BMW i3 Concept has room for two. BMW i Pedelec.

kWh lithium-ion battery pack (from the Jetta Hybrid), which stores the kinetic energy recovered from regenerative braking; assists in the starting phase of the fuel cell; and adds a dynamic boost to the maximum acceleration of the Golf SportWagen. The hydrogen is stored in the tanks at a pressure of 700 bar (10,150 psi).

The lithium in the lithiated graphite chemically reduces in situ the polysulfide Li 2 S 6 in liquid electrolyte to insoluble Li 2 S as a cathode material for rechargeable Li?S For example, the polysulfide Li 2 S 6 can be electrochemically converted to sulfur/high-order polysulfides during charge (Li 2 S 6 ? S batteries. 800 mAh g ?1

One company that’s hoping to reduce our battery anxiety is Exeger , which wants to enable self-charging devices that convert ambient light into energy on the go. And if we could reduce or eliminate that problem, how would that actually influence the development of mobile and wearable tech beyond just not having to recharge as often?

When the car is braked it stores the recovered energy. The storage battery operates over the range of 220 to 460 volts—a 3-way DC/DC converter in the engine compartment equalizes the difference compared with the fuel cell’s voltage level. 3-way power DC/DC converter. mi)—i.e., about 6 kg. at a maximum rate of 1.5

The tanks can store around five kilograms of hydrogen at a pressure of 700 bar—enough to drive more than 500 kilometers (310.7 kilowatt-hours, which is recharged by recuperation or alternatively from a power socket. An outer skin made from carbon fiber reinforced polymer (CFRP) encases the inner aluminum shell.

The i3 and i8 will become the first purpose-built electric and hybrid-electric production vehicles to be made primarily from carbon fiber when they come to market in 2013 and 2014 respectively. If required, a high-voltage alternator hooked up to the combustion engine generates extra power, which is then stored in the hybrid battery.
