Embodiment Construction

[0019] The solar charger of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like figure 1 As shown, in one solution of the present invention, the solar charger 100 includes a photosensitive unit 101, a switch unit 102, a charging unit 103 and a control unit 104. The photosensitive unit 101, the switch unit 102, and the charging unit 103 are respectively connected with the control unit 104. connect. in:

[0021] The photosensitive unit 101 is used for detecting the light intensity, and provides the detected light intensity to the control unit 104 . For example, in practical applications, the photosensitive unit 101 may be a photoresistor or other photosensitive elements.

[0022] The switch unit 102 is used for opening or closing under the control of the control unit 104 to disconnect or connect the charging unit 103 with the power battery. For example, the switch unit 102 can be a relay. When the solar charger 1...

Abstract

A solar charger for charging a power battery is provided, comprising: a photo-sensitive unit configured to detect light intensity; a charging unit configured to receive a voltage transformed from solar energy and to boost the voltage for charging the power battery; a switch unit coupled between the charging unit and the power battery and configured to disconnect the charging unit from the power battery or connect the charging unit with the power battery; and a control unit coupled to each of the photo-sensitive unit, the switch unit, and the charging unit, and configured to switch on the charging unit and the switch unit when the light intensity is higher than a first predetermined value to charge the power battery.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a solar charger for charging power batteries. Background technique [0002] At present, the electric buses used in the market run on the track line with the power line erected. There is no power battery and no solar charging system on the bus. The vehicle can only drive on the road where the power line is erected, which is inconvenient to use. [0003] As we all know, solar energy is a new type of non-polluting energy, which is easy to obtain and will not pollute the environment. However, most of the current solar chargers are used for low-power devices such as mobile phones, cameras, and emergency lights, while there are very few high-power solar chargers for electric vehicles such as electric buses. [0004] Therefore, how to provide a high-power solar charger for electric buses and automobiles is a problem that needs to be solved. SUMMARY OF THE INVENTION [0005] Aiming a...
