|Electromobile for recreation zones with combined electric power plant based on air-aluminium electrochemical generator|
The electromobile for recreation zones “Shuttle 4” of company Textron divisions E-Z-GO along with similar electromobiles of other companis is widely used for transportation of passengers, delivery of light cargoes in resort hotels, in reserves, zoos and so on. The battery of 8 lead accumulators as origin electric power plant (the total weight is 224 kg, capacity is 4800 W·h) allows the electromobile to run without additional recharge about 50 km.
Replacement of the base electric power plant on combined consisting of an energy source—air-aluminium electrochemical generator and power source—starter battery of lead accumulators has allowed to reduce the power plant weight on 80 kg. The power capacity of combined electric power plant is 19960 W·h. Magnifying of plant power capacity together with reduction of its mass characteristics has allowed to increase electromobile haulage in 5 times (to 250 km). The combination principle at which the battery of accumulators provides a covering of peak loadings at take off, at overcoming of road upgrades, and the air-aluminium electrochemical generator provides length of run at movement in a cruising mode with a simultaneous charge of accumulators, can be transferred on other more powerful electromobiles. The specific energy of combined electric power plant is 140 W·h per kg at specific energy of the air-aluminium electrochemical generator of 270 W·h per kg, that above than of lithium rechargeable batteries.
The cost of the air-aluminium electrochemical generator including in combined power plant and created in laboratory conditions is 60 000 rubles and can be decreased at mass production in 3–4 times.
The air-aluminium generator life time is 10 000 hours in mode of energy generating and is more than 20 years in storage mode without electrolyte. The cost of the electric power generated in it is defined basically by cost of anodes and estimated ∼0.05 rubles per W.h, that is comparable to cost of the electric power generated by air-hydrogen fuel cells and much more low than in other similar batteries. The cost of one kilometer of a way is about 5 rubles that in 2 times above the cost of kilometer which overcome by the car with the petrol engine.
