Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. The membrane-less design enables power densities of 0.795?W?cm 2 at room temperature and atmospheric pressure, with a round-trip voltage efficiency of 92% at 25% of peak power.

Tech: How do Hybrid & Plug-in Hybrid Batteries Recharge? Do I Need to Plug a Hybrid In?

Clean Fleet Report

Fast-forward about 10 years and a new type of hybrid came on the scene—the plug-in hybrid, and it does require plugging in to charge the onboard battery to maximize efficiency (without plugging in it functions like a normal hybrid). In addition, when in the generator mode, the internal combustion (usually gas) engine charges the battery pack.

CEA and Renault Group develop a very high efficiency bidirectional on-board charger

Green Car Congress

The result of nearly three years of research and the subject of 11 joint patents, this power converter, developed from innovative materials and more compact, will reduce energy losses by 30%, improve the vehicle’s recharging time and guarantee the battery’s durability. Further, it will be bidirectional.

However, they cannot efficiently handle peak power demands or recapture energy in today’s applications because they discharge and recharge slowly. Whereas, Ultracapacitors deliver quick bursts of energy during peak power demands, then quickly store energy and capture excess power that is otherwise lost.
