Fraunhofer ICT Working on New Redox Flow Batteries with Improved Capacity for EV Applications

Green Car Congress

OCTOBER 15, 2009

Redox flow batteries (RFB) are chemical energy storage devices, and use dissolved redox couples (an oxidizing agent and a reducing agent in an electron transfer process) held in separate external tanks; electricity is converted in a separate power module. The devices could theoretically be recharged at a station in a few minutes. “

In doing so the power electronics convert the direct current (DC) stored in the battery into alternating current (AC) and use this to drive the motor. Via a DC/DC converter it also supplies the vehicle’s circuitry with voltage of 12 V. A completely depleted battery is recharged in this way within nine hours. D1, D2, D3.
