Abstract

The invention provides a power supply component. The power supply component adopts a series-connected switching plug, a parallel-connected switching plug and a switching socket. In the prior art, an equalization charging mode is adopted so that realization cost is too high and practicability is poor. By using the power supply component of the invention, when an electric vehicle needs to be driven, the series-connected switching plug is plugged into the switching socket and a direct-current conductive component of the series-connected switching plug is connected to an anode and a cathode of electric vehicle cells so that at least two electric vehicle cells of one electric vehicle form a successive series connection relation and the electric vehicle cells can normally provide power for the outside world. When the electric vehicle cells need to be charged, the series-connected switching plug is pulled out of the switching socket and then the parallel-connected switching plug is plugged into the switching socket so that a connection relation of the any two electric vehicle cells is adjusted to a parallel connection relation from a series connection relation. Therefore, a form mode and a charging mode can be rapidly and safely switched, cost is reduced and simultaneously the practicality is increased.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular, to a power supply assembly, a charging method and a system of an electric vehicle battery, and the electric vehicle. Background technique [0002] Electric vehicles (comprising electric bicycles, electric tricycles, and electric four-wheel vehicles) are more and more appearing in people's daily life as a convenient means of transportation. After driving an electric vehicle for a long time, it is necessary to charge the electric vehicle. The following is an introduction to the content related to the charging of the electric vehicle. [0003] In related technologies, electric vehicles are mostly powered by lead-acid batteries. When in use, usually four, five or even more single-cell lead-acid batteries (such as 12V for each lead-acid battery) are connected in series to form 48V, 60V, or even higher voltage battery packs. Whether in the discharge (vehicle driving process) or in the ...
