It means using electrical energy during the low electrical load period to pump water to the upper tank, and then releasing the water to the lower tank to generate electricity during the charging period state-of-the-art electricity.
The water in the reservoir upstream of the pumped storage plant is equivalent to stored electrical energy, while the reservoir downstream is equivalent to a large “power bank” . Pumped storage power plants can use excess electricity from the power grid to run motors at night when power consumption is low to pump water from downstream reservoirs upstream and store it for during the day, when energy consumption is at its peak, water from the reservoirs can be stored. pumped to drive turbines to carry out work, converting the potential energy of water into electrical energy.
Pumped storage power plants can adjust the peak and valley differences of the power grid and improve the stability and reliability of the power system. They constitute an important means of energy storage.
If the power bank is filled with water, it can be charged but not discharged
The chemical reactions of throwing the power bank into water are:
1. Water is an electrolyte and is stored in The lithium ions and electrolytes of the power bank dissolve in water, and the electrolyte of the power bank decomposes into acids and alkalis, releasing hydrogen and l 'oxygen.
2. The aluminum alloy shell will react with oxygen in the water to generate aluminum hydroxide and release hydrogen.
3. Some power banks also include lithium batteries. Lithium batteries may explode or catch fire whenWhen exposed to water, lithium reacts quickly with oxygen in water to generate hydrogen and alkaline lithium oxide.
Would the questioner want to ask: “Can the power bank still be charged if it is soaked in water? " can't. The power bank cannot be used once it has been filled with water. Water will cause an internal short circuit and the short circuit will burn the internal components. Do not continue to charge and use the power bank to avoid electricity risk. shock or explosion. The external battery cannot be charged if it is filled with water. A power bank is a mobile power source and a mobile charger is a portable device that can be carried by individuals and can store electricity on its own.
