Abstract

The invention discloses an air supply system for a zinc-air power battery pack. The air supply system comprises an air blower, an air inlet pipeline, the zinc-air power battery pack, an air outlet pipeline, a controller, a heater, a first temperature sensor, a first electromagnetic valve, a second temperature sensor and a second electromagnetic valve, wherein the air blower, the air inlet pipeline, the zinc-air power battery pack and the air outlet pipeline are sequentially connected; the heater, the first temperature sensor, the first electromagnetic valve, the second temperature sensor and the second electromagnetic valve are connected with the controller; the heater is arranged on the end part, close to the air blower, of the air inlet pipeline; the first electromagnetic valve is arranged on the end part, close to the zinc-air power battery pack, of the air inlet pipeline; the first temperature sensor is arranged on the air inlet pipeline between the air blower and the first electromagnetic valve; the second electromagnetic valve is arranged on the end part, close to the zinc-air power battery pack, of the air outlet pipeline; and the second temperature sensor is arranged on the air outlet pipeline between the zinc-air power battery pack and the second electromagnetic valve. The system can block air to prevent self-discharging in the non-working state of a zinc-air power battery, can be started at low temperature to make the performance of the battery normally developed, and also can be self-powered on to start the controller to control timely and accurate air supply.

Description

technical field [0001] The invention relates to a zinc-air power battery, in particular to an air supply system for a zinc-air power battery pack. Background technique [0002] The chemical reaction of zinc-air batteries is similar to that of ordinary alkaline batteries. The basic working principle is that the zinc on the negative electrode of the battery and the OH in the electrolyte - An electrochemical reaction (negative electrode reaction) occurs and electrons are released; at the same time, the catalyst in the GDE (gas diffusion electrode or air positive electrode) reaction layer is in contact with the electrolyte and the oxygen in the air that enters the battery through diffusion to absorb electrons and generate Electrochemical reaction (cathode reaction). Since the charging process of the zinc-air battery is very slow, after the zinc plate or zinc particles of the negative electrode of the zinc-air battery are oxidized to zinc oxide during the discharge process and b...
