Abstract

The invention provides an electric quantity detection and display device and a method thereof. The device is arranged in an electric vehicle which is provided with a battery unit, and comprises a pulse wave detector, a voltage measuring circuit, an electric quantity measuring circuit, a microcontroller and a display unit, wherein the pulse wave detector is used for detecting a voltage value and a current valve fed back by the battery unit; the voltage measuring circuit and the current measuring circuit are electrically connected to the pulse wave detector, and are used for measuring the voltage value and the current value of the battery unit; an electric quantity mapping table is built in the microcontroller according to the power characteristic of the battery unit; and the electric quantity value of the battery unit is acquired by matching the electric quantity mapping table with the measured voltage value and current value.

Description

【Technical field】 [0001] The invention relates to a power detection and display device, in particular to a power detection and display device suitable for electric vehicles. 【Background technique】 [0002] With the increasing awareness of environmental protection, the design and development of electric vehicles has been paid more and more attention by the industry. Electric vehicles are very environmentally friendly. When charging, they are just like charging a mobile phone. You only need to connect the plug to the mains to charge. When electric vehicles are used, they will not emit suspended particles, carbon monoxide, hydrocarbons, nitrogen oxides, etc. that cause air pollution and affect health, and will not produce carbon dioxide that causes global warming. In today's era of global warming, electric vehicles are increasingly accepted by countries all over the world, and their related products include: electric bicycles, electric motorcycles, electric scooters, etc., all...
