Leo has patented technologies to feed zinc balls into the system automatically, to collect sludge in the filter, and to stop the generation of electricity as soon as the battery is fully charged, or the moment the driver does not want to charge the battery any further from the ZAFCG.
ZAFCG, which underwent an evaluation process conducted by the government officials, demonstrated that 1kg of zinc balls can generate 12.5kW electric energy in ZAFCG that enables Leo’s electric compact car to run 178 miles.
And since one-liter container can carry 7.2kg of zinc balls, it is expected that a compact EV can run 1,600 miles with a three-liter zinc tank, which occupies less space in the car than an engine generator plug-in hybrid EV.
Dr Kang, CEO of Leo Motors, said: “In Korea, we believe the energy cost efficiency of zinc used in ZAFCG can compete against crude oil, not only in EVs but in many circumstances. For example, a thermoelectric power plant can replace oil with zinc without cost burden, and in doing so can make itself into a zero emission thermoelectric power plant.”
