Battery pack and battery filling system

Abstract

The invention relates to the field of charging and battery placing, in particular to a battery pack and a battery filling system. The invention aims to solve the problems of low replacement efficiencyand low reliability in an existing battery unit replacement scheme. For this purpose, the battery pack of the present invention comprises a housing, and a transmission mechanism and a plurality of battery units disposed within the housing, each battery unit comprising at least one cylindrical battery; a circulation channel is arranged in the housing, and a battery inlet and a battery outlet are also arranged on the housing, and the battery inlet and the battery outlet are arranged on both sides of the housing along the axial direction of the battery; and the transmission mechanism is arrangedto drive the plurality of battery unis to move to the battery inlet in sequence along the circulation channel. The battery inlet and the battery outlet are arranged on both sides of the shell along the axial direction of the battery, so that when the battery is replaced, the transmission mechanism does not need to be replaced together, only a fully charged battery is used to eject a power-lack battery, the replacement efficiency of the battery is improved, and the replacement of the battery is convenient and quick.

Description

technical field [0001] The invention relates to the field of battery charging and replacement, in particular to a battery pack and a battery filling system. Background technique [0002] With the promotion of electric vehicles, how to quickly and effectively provide electric energy supply for electric vehicles has become a matter of great concern to car owners and major manufacturers. The mainstream power supply schemes currently on the market are mainly divided into charging schemes and battery replacement schemes. Compared with the charging scheme, the battery replacement scheme is one of the main development directions of electric energy supply because it can complete the power supply of electric vehicles in a very short time and will not affect the service life of the power battery. The traditional battery replacement solution is usually carried out in the charging and swapping station, and the battery pack needs to be removed for replacement when the battery is replace...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problems of low replacement efficiency and low reliability existing in the existing battery unit replacement scheme, the present invention provides a battery pack, which includes a casing and is arranged on the The transmission mechanism and a plurality of battery units in the casing, each of the battery cells includes at least one cylindrical battery; a circulation channel is arranged in the casing, and a battery inlet and a battery outlet are also arranged on the casing. The battery inlet and the battery outlet are arranged on both sides of the casing along the axial direction of the battery; the transmission mechanism is configured to drive the plurality of battery units to move sequentially along the circulation channel to the battery inlet , so that the fully charged battery enters the housing from the battery inlet, and the weak battery is ejected from the battery outlet
