Electric quantity display mode of battery pack of electric vehicle

Abstract

The invention discloses an electric quantity display mode for a battery pack of an electric vehicle. According to a novel electric automobile charging device (the invention patent application number is 2024117007980 and the invention patent application number is 2024228876345) declared by the inventor, an electric automobile power battery is divided into N battery packs, and the N battery packs jointly form a large battery pack. The battery packs jointly and respectively display the electric quantity on an instrument panel in front of a driver or on the right side, so that the residual electric quantity of each battery pack and the total residual electric quantity can be visually seen, and a basis is provided for charging the battery pack. When driving, a user can know that the automobile is knocked out by looking at an instrument panel in front or on the right side without spending too much time, and if the automobile needs to be knocked out by more than two or three seconds, driving is not safe, and collision and turnover are possible at any time. Practice shows that the sight is dangerous when leaving the front road for one second, and safety accidents may occur. The invention is a deepened, refined and extended invention on the basis of a novel charging device of an electric automobile.

Description

Technical Field

[0001] According to the patented new electric vehicle charging device (invention patent application number 2024117007980 and utility model patent application number 2024228876345) applied by me, the electric vehicle power battery will be divided into N battery packs, which together form a large battery pack. Each battery pack displays the power together and separately, which is displayed on the dashboard in front of the driver or on the right side, and the remaining power of each battery group and the overall remaining power can be intuitively seen. This is a deepening, refinement, and extension invention based on the new electric vehicle charging device. Background Art

[0002] The existing display method of power batteries is to display the remaining power of the entire battery on a horizontal bar or vertical column block. There is no display method for N groups of batteries, that is, there is no horizontal bar block set, vertical column block set and digital block set. In the future, when power batteries are divided into N groups, it will be necessary to invent a convenient and intuitive display method. Summary of the invention

[0003] Purpose of the invention: To facilitate the driver to grasp the remaining power of each battery group and the overall remaining power of the electric vehicle at any time, to provide a basis for charging, and to charge the battery group that is insufficient.

[0004] Technical solution: ① Horizontal power bar set: Depending on the number of battery packs, the horizontal power bars are divided into one row, two rows, three rows or N rows. ② Vertical power bar set: The vertical power bars are arranged horizontally from left to right or from right to left. ③ Digital block set: One is that the digital blocks are stacked in one row, two rows, three rows or N rows; the other is that the digital blocks are arranged horizontally from left to right or from right to left.

[0005] 4. Description of the accompanying drawings.

[0006] Figure 1 Horizontal power bar set: Each power bar shows the remaining power of a battery pack. Here, the first battery pack is half-charged, and the 2-6 battery packs are fully charged.

[0007] Figure 2 Vertical power bar collection: Each power bar shows the remaining power of a battery pack. Here, the first battery pack is half-charged, and the 2-8 battery packs are fully charged.

[0008] Figure 3 A collection of digital blocks: Each battery block shows the remaining power of a battery pack. Here, the first battery pack is half-charged, and the second to sixth batteries are fully charged. The numbers and blocks can be in a variety of different colors.

[0009] 5. Specific implementation methods.

[0010] The sensor detects and analyzes the power of each battery group, that is, by analyzing the voltage, current and temperature, the remaining power (SOC) of the battery is determined. Then the analog signal is converted into a digital signal so that the vehicle electronic control unit (ECU) can process it. The analog signal is converted into a digital signal through an analog-to-digital converter (ADC), which converts the continuous analog signal from the sensor into a discrete digital signal. Then it is displayed through a liquid crystal display (LCD) or a light-emitting diode display (LED), that is, the ECU transmits the processed power data to the display screen in the form of a digital signal, and the display screen presents the power to the driver in the form of numbers or graphics (power bar) through a specific drive circuit and software program.

[0011] 6. Important significance.

[0012] It is convenient for the driver to intuitively grasp the remaining power of each battery group and the overall remaining power of the whole vehicle, and provide a basis for which battery group to charge. When driving, just glance at the dashboard in front or on the right and you will know the number. You don't need to spend too much time to check. If you need to spend more than two or three seconds to check, driving will be unsafe and you may crash or roll over at any time. Practice shows that it is dangerous to take your eyes off the road ahead for even a second, and safety accidents may occur.

Claims

1. Overall technical conception of the power display method of electric vehicle power battery pack.

2. Combine centralized and separate displays of power battery pack capacity.

3. The display is divided into a horizontal power bar set, a vertical power bar set and a digital block set.

4. The display of the horizontal and vertical power bars uses the filling color to indicate the remaining power, including black and white.

5. The display of the digital block indicates the remaining power with the size of the number, usually 0-10, 0 for no power, 10 for full power; it can also be 0-N, 0 for no power, N for full power. The numbers and blocks can be of various colors.

6. Each power bar or power block corresponds to one battery pack, and N power bars or power blocks correspond to N battery packs. 7.N battery packs together form a large battery pack.
