Abstract

The embodiment of the invention provides a supply unit and a power supply system. The supply unit comprises a battery module, a first fire extinguishing device and a second fire extinguishing device, wherein the first fire extinguishing device and the second fire extinguishing device are fixedly connected with the two ends of the battery module correspondingly. The battery module comprises a plurality of battery individuals. One end of each battery individual is connected with the first fire extinguishing device, and the other end of each battery individual is connected with the second fire extinguishing device. The first fire extinguishing device comprises a first fire extinguishing bin shell and a first installation mechanism, and the first fire extinguishing bin shell is arranged on the side, far away from the battery module, of the first installation mechanism. The second fire extinguishing device comprises a second fire extinguishing bin shell and a second installation mechanism, and the second fire extinguishing bin shell is arranged on the side, far away from the battery module, of the second installation mechanism. The supply unit and the power supply system can extinguish fire for the battery individuals when the battery individuals in the battery module explode, the situation that the whole battery module explodes and is damaged due to the exploded battery individuals cannot occur to the battery module, and the safety and reliability of batteries are guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery safety, in particular to a power supply device and a power supply system. Background technique [0002] In recent years, with the increasingly widespread application of batteries, examples of safety accidents occurring in batteries (eg, lithium batteries) are also common. [0003] A huge amount of energy is stored inside the lithium battery. When the ambient temperature of the lithium battery is improperly controlled or an internal short circuit occurs, the lithium battery is extremely prone to accidents such as explosion and fire. If proper measures are not taken, when an accident occurs in one battery, it will spread to other adjacent batteries, causing the fire to spread, and then causing a bigger accident. [0004] For now, the battery packs used in daily life are composed of multiple rows and rows of battery cells. Usually, there are no fire extinguishing facilities on the battery cells, but...
