Embodiment Construction

[0006] figure 1 Energy supply structure diagram of the present invention

[0007] In addition to the structure and devices of ordinary electric vehicles, the refillable electric vehicle of the present invention is specially provided with a refillable energy supply system.

[0008] The above-mentioned reciprocal energy supply system includes two identical large-capacity batteries A and B, a bidirectional circuit control system, a charging circuit, a discharging circuit, a discharge detection circuit, and a charge detection circuit.

[0009] The large-capacity batteries A and B are respectively connected with a bidirectional circuit control system with a discharge circuit and a charge circuit, and are respectively connected with the bidirectional circuit control system with a discharge capacity detection circuit and a charge capacity detection circuit. When the large-capacity battery A is used as the supply source, the large-capacity battery A discharges to the two-way circuit ...

Abstract

The invention relates to an energy supply system of an electric automobile, which comprises two same high-capacity batteries A and B and a bilateral circuit control system, wherein the high-capacity battery A transmits electric energy to a power system, a lighting system, an air conditioning audio-video system and the like through the bilateral circuit control system, and simultaneously charges the high-capacity battery B through the bilateral circuit control system; and when detecting that the electric energy of the high-capacity battery A is lower than an approved standard, the bilateral circuit control system automatically changes the high-capacity battery B into a supply battery to charge the large-capacity battery A while supplying electric quantity to other systems. The energy supply system implemented through the technical scheme needs no external power supply for battery charging under normal condition to avoid the abuse that the prior electric automobile is troublesome to charge.

Description

technical field [0001] The present invention relates to an automobile, and more specifically relates to an electric automobile. Background technique [0002] With the successive development of large-capacity batteries such as lithium-ion batteries, lithium iron phosphate batteries, and fuel cells, pure electric vehicles have become a bright spot in the automotive market due to their huge advantages of energy saving, environmental protection, and low driving costs. At present, electric bicycles have been recognized by the market as a mature product, and some automobile manufacturers have launched electric vehicles one after another. However, it is very troublesome to recharge the electric vehicle battery. At the same time, the current pure electric vehicle battery has a limited mileage on a single charge, and the battery cannot be charged during the exercise. Contents of the invention [0003] The object of the present invention is to provide a self-charging electric vehic...
