Wireless charging battery pack for electric vehicle, charging method for wireless charging battery pack, and electric vehicle

Abstract

The invention relates to a wireless charging battery pack for an electric vehicle, a charging method for the wireless charging battery pack, and the electric vehicle. The wireless charging battery pack for the electric vehicle comprises a battery pack housing, a battery pack formed by connection of single batteries and a wireless charging circuit; the wireless charging circuit comprises a coupling receiving coil, a rectifying voltage-stabilizing module, a singe chip microcomputer module, and a wireless receiving module, a display module and a charging management module connected with the singe chip microcomputer module separately; and the coupling receiving coil is connected with the battery pack through the rectifying voltage-stabilizing module and the charging management module. The charging method comprises the steps that: the wireless charging battery pack is matched with a wireless charging apparatus; the coupling receiving coil close to the wireless charging apparatus generates induced voltage; the induced voltage is subjected to full-wave rectification, voltage reduction and voltage stabilization treatment through the rectifying voltage-stabilizing module to output constant voltage to the charging management module; and the battery pack is charged by the charging management module. Charging lines and connectors are not required by the wireless charging battery pack, so that the shortcomings of high possibility of intertwining and cracking of the charging lines are avoided; and the wireless charging battery pack is convenient to use and high in reliability.

Description

technical field [0001] The invention relates to a power battery for an electric vehicle, in particular to a wireless rechargeable battery pack for an electric vehicle, a charging method thereof and the electric vehicle. Background technique [0002] At present, electric vehicles and electric bicycles are becoming more and more popular, and charging the batteries of electric vehicles and electric bicycles is still at the stage of using wired chargers, that is, charging batteries need to be connected to charging piles and chargers by connecting charging cables. Charging, there are not only bulky chargers but also troublesome wires, and various wires are also tangled and difficult to distinguish. It may be broken or damaged, resulting in failure to use normally. In addition, at present, users cannot understand the status of electric vehicle batteries well, and cannot maintain them in time, which has potential safety hazards and affects the life of electric vehicle battery pack...

AI Technical Summary

Problems solved by technology

[0003] The invention mainly solves the problem that the power battery of the original electric vehicle and electric bicycle needs to be charged by connecting the charger with a charging line. The charging line is easy to be entangled and difficult to distinguish. It is easy to be damaged, and the charging line is also prone to breakage and damage, resulting in technical problems that cannot be used normally; a wireless rechargeable battery pack for electric vehicles and its charging method are provided, which do not need to use a charging line and are charged through a wireless connection to avoid Eliminates the defects that the charging line is easy to tangle, easy to break, and easy to damage. It is not only easy to use, but also has high reliability

[0004] At the same time, the present invention solves the technical problems that current users cannot understand the state of electric vehicle batteries well, cannot maintain them in time, has potential safety hazards, and affects the service life of electric vehicle battery packs; it provides a wireless rechargeable battery pack for electric vehicles and its Charging method, which can alarm various abnormal states of the battery and remind the user to deal with it in time, thereby improving safety and prolonging the service life of the battery pack of electric vehicles
