Solar charging device for electric vehicle battery

Abstract

The invention relates to a solar charging device for an electric vehicle battery, comprising a storage box composed of a box frame and solar cell panels, a photovoltaic controller and connection leads. The solar charging device for the electric vehicle battery is characterized in that the solar cell panels installed on three side faces of the box body of the storage box are connected in parallel, and then sequentially connected with the solar cell panel installed on the upper surface of the cover body of the storage box and the photovoltaic controller inside the cover body of the storage box in series; the anode output end and the cathode output end of the photovoltaic controller are respectively connected with the anode and the cathode of the electric vehicle battery through the connection leads; and the contact points of the electrodes of the solar cell panels, the connection leads and the photovoltaic controller are all packaged by adopting silica gel. The solar charging device for the electric vehicle battery has the advantages of simple structure, low cost, environment friendliness and practicability and complete reliability, and is widely applied to electric motorcycles, electric bicycles and the like.

Description

technical field [0001] The invention relates to a solar charging device, in particular to a solar charging device for batteries of electric vehicles. Background technique [0002] At present, the country is vigorously promoting new energy. Under this background, all kinds of electric vehicles and hybrid vehicles emerge at the historic moment, especially the most rapid development of electric vehicles with two wheels, which have gradually entered thousands of households and become the main means of transportation. However, since most of the batteries of two-wheeled electric vehicles are charged by household power sources, there are the following limitations in the application and popularization process: 1. The travel distance is short. Due to the small capacity of the electric vehicle battery, it can only travel 50-70 kilometers on one charge; 2. It is inconvenient to charge. Existing two-wheeled electric vehicles are all equipped with chargers connected to household power ...

AI Technical Summary

Problems solved by technology

However, because most of the batteries of two-wheeled electric vehicles are charged by household power sources, there are the following limitations in the application and promotion process: 1. Short travel

This technical solution can make full use of solar energy to realize "charging while walking" for electric vehicle batteries, and has the advantages of environmental protection, energy saving, and convenient use. However, in the actual application process, there are still the following limitations: 1. Complex structure and high cost

The charging device needs 5 solar panels, 2 controllers and 1 additional storage battery, the structure is complicated and the cost is high, and these accessories also increase the load of the electric vehicle; 2. Lack of safety protection measures

The charging device directly installs the relevant control circuit and electronic components inside the rear box, which will easily cause a short circuit in case of rain
