Abstract

The invention discloses a wireless battery pack for an electric bicycle. An instrument of the wireless battery pack comprises a liquid crystal display, an instrument single-chip microcomputer and a battery pack; a power management circuit is arranged in the battery pack; the instrument single-chip microcomputer is connected with an instrument wireless receiving and sending module through a receiving and sending control line; signals are transmitted between the instrument wireless receiving and sending module and the instrument single-chip microcomputer; a battery pack wireless receiving and sending module is arranged in the battery pack; and signals are transmitted between the battery pack wireless receiving and sending module and the power management circuit. As a wireless receiving and sending circuit is installed inside the battery pack, a wireless instrument can process information of a power management circuit, and information can be interchanged between the wireless instrument and the electric bicycle battery.

Description

technical field [0001] The invention relates to the field of battery packs for electric bicycles, and more specifically relates to a wireless battery pack for electric bicycles. Background technique [0002] At present, electric bicycle displays generally adopt wired signal transmission. For high-end electric vehicles, due to differences in bicycle frames, it is necessary to customize wire harnesses of different lengths. For electric vehicle instrument manufacturers, customizing instruments with different lead lengths is a time-consuming and laborious task, which is not conducive to mass production. Therefore, there is a market demand for the design of wireless electric vehicle instruments using public wireless frequency bands, which can save the connection harness between the instrument and other components. [0003] Electric vehicle batteries are single cells connected in series to obtain different voltages, and single cells connected in parallel to obtain different capac...
