Abstract

The invention provides an electric vehicle, an electric vehicle solar charging method and an electric vehicle solar charging device. The electric vehicle comprises a power battery, a storage battery and a solar cell. The electric vehicle solar charging method comprises the steps of: detecting residual electric quantity of the storage battery; detecting whether the solar cell generates a current; generating a first charging signal when detecting and determining that the residual electric quantity of the storage battery is lower than a first preset value and the solar cell generates current; converting the current of the solar cell into a charging current of the storage battery according to the first charging signal; generating a second charging signal when detecting and determining that the residual electric quantity of the storage battery is higher than a second preset value and the solar cell generates current; and converting the current of the solar cell into a charging current of the power battery according to the second charging signal, wherein the second preset value is greater than the first preset value. The electric vehicle, the electric vehicle solar charging method and the electric vehicle solar charging device can achieve bidirectional charging of the storage battery and the power battery by utilizing solar energy, and ensure normal use of the storage battery and the power battery.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a solar charging method and device for an electric vehicle and the electric vehicle. Background technique [0002] With the increase of car ownership, cars using fossil fuels as energy sources have an increasing impact on the environment. The exhaust gas produced by engines contains a variety of harmful and toxic substances, which will have adverse effects on environmental safety and human health. The emergence of electric vehicles has solved the problem of environmental pollution caused by ordinary vehicles. Electric vehicles use power batteries as the power source, and use batteries as the power source for low-voltage electrical appliances on the vehicle. No exhaust gas will be generated during driving, and it is more environmentally friendly. However, if the storage battery or power battery in the existing electric vehicle has low power and cannot be charged in time, it will ...
