Description

Technical Field

[0001] The present application belongs to the technical field of electric bicycles, and specifically relates to an electric bicycle battery pack with a fuel meter function. Background Art

[0002] The electric bicycle battery packs currently on the market only have simple 4 LED indicators to indicate the battery power status, and cannot truly monitor the battery life status itself. Generally, electric vehicle battery packs are a combination of multiple series and parallel cells. If the voltage of one battery cell is too low or too high compared to the others, it is easy to trigger over-discharge or over-charge protection in advance, affecting the battery pack user experience. Utility Model Content

[0003] The purpose of the embodiment of the present application is to provide an electric bicycle battery pack with a fuel meter function. By designing an electric bicycle battery pack with a metering chip, users can better understand the battery state of charge (SOC) and battery health (SOH), thereby avoiding safety accidents caused by the battery pack working in an unhealthy state, thereby solving at least one technical problem involved in the background technology.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] An embodiment of the present application provides an electric bicycle battery pack with a fuel meter function, comprising an internal hollow shell, a display screen, and a battery pack housed in the shell, a power sensor for detecting the power of the battery pack, a temperature sensor for detecting the temperature of the battery pack, a current sensor for detecting the charging and discharging of the battery pack, and a battery management chip respectively connected to the power sensor, the temperature sensor, and the current sensor. The shell comprises a bottom plate, a side plate vertically arranged on the bottom plate, and a top plate arranged on the top of the side plate. The top plate comprises a first part arranged parallel to and spaced apart from the bottom plate and a second part extending obliquely from the first part toward the front end of the bottom plate. The top plate is also provided with a groove portion formed by being recessed toward the bottom plate, the groove portion extending from the first part to the second part, and the display screen is arranged in the groove portion located in the second part and is connected to the battery management chip.

[0006] Optionally, the display screen is an LCD display screen or an LED display screen.

[0007] Optionally, the display screen is a touch display screen.

[0008] Optionally, a BMS board housed in the shell is further included, and the BMS board is arranged on the base plate.

[0009] Optionally, the top panel and the side panels are integrally formed.

[0010] The beneficial effects of the embodiments of the present application are:

[0011] 1. Enable users to better understand the battery state of charge (SOC) and battery health (SOH), thereby avoiding safety accidents caused by unhealthy battery packs;

[0012] 2. The shell is formed in one piece and has high structural strength. By setting the top plate into a partially inclined structure, it is convenient to view the display screen and perform touch operations. In addition, a sunken groove structure is set on the top plate, which can significantly reduce the risk of damage to the display screen. BRIEF DESCRIPTION OF THE DRAWINGS
