[0002] A battery is a cup, trough or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. A lithium-ion battery is a secondary battery (rechargeable battery) that relies mainly on the movement of lithium ions between the positive and negative electrodes. During the charge and discharge process, positive lithium ions are embedded and deintercalated back and forth between the two electrodes: when charging, positive lithium ions are deintercalated from the positive electrode, embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. When charging a lithium-ion battery, a rechargeable battery holder is used;

[0003] Some existing charging stations do not have a heat dissipation structure. When charging multiple battery packs at the same time, a large amount of heat will be generated in the housing. If the heat is not dissipated in time, it will not only affect the charging safety, but also accelerate the oxidation of the circuit inside the charging station, thus reducing the service life of the charging station.

[0004] To this end, a heat dissipation structure of a battery pack charging stand is proposed. Utility Model Content
