It is reported that the maximum consumption of zinc-air battery is electric energy. The zinc oxide powder in the scrapped battery after being discharged is reduced to metal zinc powder by electrolysis, and the chemical electrolyte is decomposed. This regeneration process consumes more power.
It is understood that under normal circumstances, the zinc-air battery pack discharged on the electric vehicle requires 4.5 kWh of electric regeneration for each kilowatt-hour of electricity, that is, the regeneration to discharge is 4.5 to 1, the ratio of electricity consumption to two batteries. Compared with lead-acid batteries, nickel-hydrogen batteries, and lithium batteries, the power conversion efficiency is very low. It is equivalent to the ratio of electric energy consumed by electrolysis of water to hydrogen and hydrogen to fuel cells.
According to experts' calculations, taking a 10-meter-long bus as an example, replacing a new zinc-air battery with 250 kWh of electricity can drive 250 kilometers, which is basically 1 kilowatt-hour of electricity. According to the proportion of electricity required for electrolytic zinc, the electric loss is about 5 kWh when driving an electric car for 1 km. Jiangsu's feed-in tariff is 1 kWh, which is more than 4 cents. That is to say, if the electric car using zinc-air battery costs 1 kilometer per kilometer.
In addition, the zinc-air battery is repeatedly cycled. The whole vehicle does not contain the battery cost when it leaves the factory. It only needs a special battery compartment. It does not need a battery management system, a safety monitoring system, a car charger, a plug and socket, etc., an electric car. As long as the motor drive system and the speed controller are available, the cost of the electric vehicle will not be higher than that of the fuel vehicle of the same configuration.
Compared with the familiar lead-acid batteries and lithium batteries, electric vehicles use zinc-air batteries, and users do not have to consider the investment of a set of power batteries in a few years. In addition, the zinc-air battery does not cause an explosion accident, and is a stable chemical power source. It only needs to stop supplying oxygen to the air, and it does not react or discharge. At the same time, it is solid and does not leak electrolyte, which will not cause harm to roads and pedestrians.
