Problems solved by technology

Existing electric bicycles are equipped with several LED lights to display power reminders according to the voltage level. From this, the estimated cruising range is even more inaccurate, inaccurate and has a large error. Electric bicycles can only be promoted after they are out of power. It's embarrassing to push an electric car forward

Abstract

The invention provides an electric bicycle riding computer with a riding mileage pre-estimating function. The computer is composed of a signal sampling input circuit, an analysis and processing circuit and a liquid crystal output display circuit. A liquid crystal display screen can display the riding mileage, the battery capacity, charge and discharge efficiency, real-time voltage and real-time current of a storage battery of an electric bicycle. Control functions of the electric bicycle are integrated to form the riding computer. A single chip microcomputer can conveniently carry out data processing. Data are analyzed after being collected, the battery capacity is represented by the product (namely energy) of voltage, current and time; more accurate speed signals are obtained by combining a real-time clock and mileage pulse; a hall element is used for measuring direct current without cutting in original circuits, namely, non-energy-consumption type measurement is carried out without serial-in of a sample detecting resistor. The riding mileage can be estimated according to real-time voltage, load current, mileage pulse and the surplus capacity. A rider can know how much longer the electrical bicycle can run, and the awkward condition that electricity is used up in the midway is avoided.

Description

1. Technical field [0001] The invention relates to a single-chip computer, in particular to an electric bicycle driving computer capable of estimating the current cruising range and the budgeted cruising range according to real-time voltage, load current, mileage pulse and remaining capacity. 2. Background technology [0002] Ordinary electric vehicles identify the remaining battery power according to the voltage level, which is very inaccurate in itself, and the voltage and capacity are not linearly related (especially for old batteries). Existing electric bicycles are equipped with several LED lights to display power reminders according to the voltage level. From this, it is even more inaccurate to estimate the cruising range, which is inaccurate and has a large error. Electric bicycles can only be promoted after they are out of power. People often see them It's embarrassing to push an electric car forward. 3. Contents of the invention [0003] The purpose of the presen...
