Braking systems that store energy in batteries during braking are increasingly common in new cars, helping to reduce fuel consumption.
Today, Mazda has introduced what it claims is the first passenger car the regeneration system that uses a capacitor instead of a battery to store energy, called I-ELOOP ("Intelligent Energy Loop").
The Mazda is more than a capacitor battery, because it eliminates the need for an electric motor and can be charged and discharged quickly, so it does not deteriorate after prolonged use.
The i-ELOOP capacitor includes a new 12-25V variable voltage alternator with a layer of low electrical resistance and a dual DC / DC converter. That captures the energy that would otherwise be dissipated as heat when the driver takes his foot off the accelerator pedal and the vehicle begins to slow.
By the time the generator begins to generate electricity to 25V before sending it to the condenser, where it is stored in seconds. DC / DC then converts power from 25V to 12V, before turning the air conditioner of the car audio systems, various other electrical systems and can even charge the battery if necessary.
Mazda claims that the in-ELOOP, which will be combined with i-stop system of the company's stop-start system that reduces fuel consumption by about 10% and will be available in production vehicles in 2012.
The i-ELOOP debut public next week in Tokyo Motor Show Car Taker concept, which provides for the replacement of medium family sedan Mazda Mazda6.
