Abstract
The invention provides a circuit of a plurality of groups of power supplies for an electric vehicle, which comprises a motor, a charging interface seat and a plurality of power supplies, wherein the charging interface seat is arranged on the motor; two ends of the motor are connected with a plurality of power supplies in parallel, and all parallel circuits are provided with switch control circuit switches; the plurality of power supplies are simultaneously and respectively connected in parallel at two ends of the charging interface seat, and a full-power cut-off device and a diode are sequentially arranged between the anode of each power supply and the anode of the charging interface seat. The invention can double the running distance of the electric vehicle by two or more groups of power supplies. If the electric vehicle runs in an ultra-long distance, the running distance of the electric vehicle can be prolonged by directly replacing the battery, so that the electric vehicle can run in all distance sections.
Description
Technical Field
The invention belongs to the technical field of electric vehicles, and particularly relates to a circuit of a plurality of groups of power supplies for an electric vehicle.
Background
With the improvement of living standard, the range of activities of people is wider and wider, and the cross-regional communication activities are more and more, so that people pursuing efficiency have greater and greater dependence on vehicles. Because the gradual exhaustion of traditional energy and the increasing aggravation of environmental pollution, the country advocates green travel vigorously, encourages people to adopt a new energy transportation mode taking an electric vehicle as a leading factor. However, as is well known, the popularization of electric vehicles is restricted by factors such as charging difficulty, so that the bottleneck of popularization cannot be broken through, and electric vehicle auxiliary charging facilities such as charging stations, charging piles, quick chargers and the like also have the defects of long time consumption, limited site capacity, aggravated battery life loss and the like. The charging of the existing electric vehicle is limited, the running distance is also limited, and the electric vehicle cannot run for a long distance.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a circuit of a plurality of groups of power supplies for an electric vehicle. The electric vehicle is provided with two or more groups of power supplies, so that the running distance of the electric vehicle can be improved to the greatest extent.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a circuit of a plurality of groups of power supplies for an electric vehicle comprises a motor, a charging interface seat and a plurality of power supplies; two ends of the motor are connected with a plurality of power supplies in parallel, and all parallel circuits are provided with switch control circuit switches; the plurality of power supplies are simultaneously and respectively connected in parallel at two ends of the charging interface seat, and a full-power cut-off device and a diode are sequentially arranged between the anode of each power supply and the anode of the charging interface seat.
Furthermore, the power supply adopts a portable detachable rechargeable storage battery.
Further, the diode adopts a unidirectional current diode.
Has the advantages that: the invention can double the running distance of the electric vehicle by two or more groups of power supplies. If the electric vehicle runs in an ultra-long distance, the running distance of the electric vehicle can be prolonged by directly replacing the battery, so that the electric vehicle can run in all distance sections.
