Problems solved by technology

[0002] As cars become more and more popular, people rely more and more on cars. Among them, the power required for the ignition and lighting of cars is supplied by the power supply. At that time, people often did not know the power of the power supply. If the voltage changes, it will lead to misfire due to insufficient voltage
[0003] Taking a car with a battery as the power source as an example, if the car battery is insufficient, it will not only cause the car to fail to start and affect the lighting, but also when the car cannot start, the driver will easily neglect to check the voltage of the car battery. Therefore, a lot of unnecessary start-up time is wasted, and often driving the car forcibly will cause damage to the car battery and reduce the service life of the car battery
[0004] In order to avoid unexpected situations caused by too low voltage, a power supply voltage detection device is proposed, but because the traditional power supply voltage detection device can only display the current detected voltage value

Embodiment Construction

[0016] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0017] refer to figure 1 , figure 1 It is a schematic flow chart of an embodiment of the voltage detection method of the present invention. This embodiment is described from the perspective of a voltage detection device, where the voltage detection device may be an on-board charger or other devices capable of acquiring voltage and performing communication, which is not specifical...

Abstract

The invention discloses a voltage detection device, a voltage detection method and a device with a storage function. The voltage detection method includes: obtaining the ignition voltage or flameout voltage value of the power supply of the power equipment; judging whether the voltage value is lower than a threshold value, and if so, then Output prompt information. Through the above method, it is possible to judge the power supply voltage of the power equipment and whether it can be used normally. Therefore, the present invention avoids the influence of the low voltage on the use of the product, thereby improving the user experience.

Description

technical field [0001] The invention relates to the field of voltage detection, in particular to a voltage detection device, a voltage detection method and a device with storage function. Background technique [0002] As cars become more and more popular, people rely more and more on cars. Among them, the power required for the ignition and lighting of cars is supplied by the power supply. At that time, people often did not know the power of the power supply. If the voltage changes, it will lead to misfire due to insufficient voltage. [0003] Taking a car with a battery as the power source as an example, if the car battery is insufficient, it will not only cause the car to fail to start and affect the lighting, but also when the car cannot start, the driver will easily neglect to check the voltage of the car battery. Therefore wasting a lot of unnecessary start-up time, and often forcibly driving the car will cause damage to the car battery and reduce the service life of t...
