Abstract

The invention relates to the field of battery power supplies and discloses a power supply device based on a battery pack and a discharging method thereof. In the invention, a plurality of lithium ion battery units are sequentially and circularly switched by one switch, and each lithium ion battery unit generates pulsed discharge when switched on every time, by utilizing the property that higher current can be provided by utilizing the pulsed instant discharge of lithium ion batteries, higher current can be provided for electric equipment by the same battery pack, and therefore, the utilization rate of the batteries is improved. The power supply output can be more stable by carrying out voltage stabilization to the output of the battery pack.

Description

technical field [0001] The invention relates to the field of battery power supply, in particular to the battery pack-based power supply discharge technology. Background technique [0002] Lithium-ion batteries (Li-ion Batteries) are sometimes referred to as "lithium batteries". It uses carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. During the charge and discharge process, there is no metal lithium, only lithium ions, so it is called for lithium-ion batteries. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon used as the negative electrode has a layered structure, and it has many micropores. Lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are embedded, the higher the charging capacity. Similarly, when th...
