When the smart water meter controls the opening and closing of the water valve, the commonly used method is to install a lithium battery. The advantages of lithium batteries are lightweight, large energy, and low self-discharge rate. Even so, because the smart water meter has no recharging circuit, after a certain period of time, the lithium battery cannot provide energy for the control circuit, and the battery has to be replaced.
Even more dangerous is that if the battery power is not accurately and timely monitored, the water valve will not be able to be reliably shut down, resulting in an inability to charge and water escape. This is the fatal flaw of the smart water meter with the lithium battery installed inside.
In order to solve the bottleneck problem that restricts the development of smart water meters, Jinzhou Kaimei Power Co., Ltd. has developed a brand-new supercapacitor for smart water meters that replaces lithium batteries. A supercapacitor is a passive device that has been mass-produced in recent years. It is between batteries and ordinary capacitors. It has the characteristics of high-current fast charge and discharge of capacitors, as well as the energy storage characteristics of batteries, and has a long repeated service life. When using electrons between moving conductors (instead of relying on chemical reactions) to release current to provide power to the device.
Compared with smart water meters with built-in lithium batteries, this solution uses supercapacitors to replace lithium batteries and encapsulate them in the water meter, while external dry batteries are used to supply power. Usually, the dry battery provides the energy required by the water meter circuit and charges the super capacitor. When it is necessary to open the water valve, first check whether the supercapacitor stores enough energy. If it does not store enough energy, the water valve will not be opened. When it is tested that it stores enough energy, The external battery provides energy to open the water valve; when the water valve needs to be turned off, if the external battery cannot provide energy to turn off the water valve, the supercapacitor will provide energy to shut off the water valve at this moment. Like a water storage tank, it stores water at ordinary times and provides necessary water when the water is stopped.
