Problems solved by technology

Using power batteries requires frequent charging, such as figure 1 As shown, when charging the power battery, the power battery 3 is connected to the charging device 2, and the charging device 2 is connected to the power source 1. The charging device 2 and the charging device are two independent devices. If the power supply purchased by the user does not match the charging device, the following problems may occur during use: 1. The power supply protection is triggered and cannot be used normally.
2. Low charging efficiency

Embodiment 1

[0021] Embodiment 1: A power adaptive charging method

[0022] Please refer to figure 2 , the power adaptive charging method includes the following steps:

[0023] Step S1, the charging device samples the output data of the power supply. The output data here may be any one or more of current, voltage or power. The current sampling technology itself, the voltage sampling technology itself and the power sampling technology itself are all common knowledge in the field, and will not be repeated here.

[0024] Step S2, comparing the output data with the corresponding nominal value of the power supply to obtain the working condition of the power supply. The operating conditions here include: overload operating conditions, low load operating conditions and full load operating conditions. When the output data adopts current, the corresponding nominal value of the power supply is the rated output current; when the output data adopts voltage, the corresponding nominal value of the ...

Embodiment 2

[0027] Embodiment 2: Another Power Adaptive Charging Method

[0028] As a better embodiment, on the basis of Embodiment 1, the power adaptive charging method further includes the following steps: sampling the voltage of the charged load (that is, the power battery 3 ), when the charged load When the voltage is close to the nominal voltage of the charged load, the output power of the charging device itself is reduced, and the charged load is slowly charged, so as to protect the charged battery and prolong its service life.

[0029] The above power adaptive charging method can be expressed in computer language to form a power adaptive charging program.

Embodiment 3

[0030] Embodiment 3: A power adaptive charging device

[0031] The power-adaptive charging device includes a processor, a memory, and a power-adaptive charging program stored in the memory and operable by the processor. When the power-adaptive charging program is executed by the processor, the above-mentioned The steps of the power adaptive charging method.

Abstract

The invention discloses a power adaptive charging method and a charging device. The charging method comprises the following steps: the charging device samples the output data of a power supply; the output data are compared with the corresponding nominal value of the power supply to acquire the working condition of the power supply; when the power supply operates in an overload condition, the charging device reduces the own output power to enable the power supply to operate in a full load working condition; and when the power supply operates in a low load condition, the charging device raises the own output power to enable the power supply to operate in a full load working condition. The charging device includes a processor, a memory, and a power adaptive charging program stored in the memory and operable in the processor. Triggering of power protection due to mismatch between the charging device and the power supply can be avoided, the charging device and the power supply can work at the optimal power, and the charging efficiency reaches the highest.

Description

technical field [0001] The invention relates to a charging method and a charging device, in particular to a power adaptive charging method and a power adaptive charging device capable of adaptively adjusting output power according to a power source and a load. Background technique [0002] UAVs have been widely used in many fields, such as aerial photography, crop spraying, express delivery, value insurance, etc. Most of these UAVs use power batteries as energy sources. In addition, power batteries are also widely used in other equipment, such as electric vehicles. Using power batteries requires frequent charging, such as figure 1 As shown, when charging the power battery, the power battery 3 is connected to the charging device 2, and the charging device 2 is connected to the power source 1. The charging device 2 and the charging device are two independent devices. If the power supply purchased by the user does not match the charging device, the following problems may occu...
