Charging device for electric automobile during driving process

Abstract

The invention discloses a charging device for an electric automobile during a driving process. While the charging device achieves charging of the electric automobile during the driving process, the vehicle is not restricted, can freely change lanes and drives in an overtaking manner as ordinary vehicles. Multiple groups of positive wires and negative wires are laid on the ground at intervals, thecharging device is installed on the bottom of the electric automobile, two ends of each of electricity taking poles of the charging device are connected with two poles of a charging circuit of the electric automobile, so that the purpose of charging is achieved; and when the automobile changes the lanes, through recognition of a camera, the direction of an electricity taking pole group is automatically controlled to be the same as the positive and negative wires of the ground, and through cooperation of the length of the electricity taking pole and spacing of the pole wires of the ground, at least one electricity taking pole is guaranteed to from a closed loop circuit at any time when the lanes are changed, thereby ensuring continuity of charging during a lane change, and an unrestricted lane change is achieved during a charging process.

Description

technical field [0001] The invention belongs to the field of charging devices for electric vehicles, and in particular relates to a charging device for electric vehicles during running, in particular to a charging device for unrestricted electric vehicles that can change lanes freely. Background technique [0002] The development of electric vehicles has been advancing by leaps and bounds in recent years, and the market share is getting higher and higher. The pure electrification of vehicles, as a national strategic deployment, is steadily advancing. However, due to the limitation of battery technology at the current stage, the cruising range of electric vehicles is still difficult to meet the needs of consumers. Short cruising range, few charging devices, and long waiting time have become the primary problems in the promotion of electric vehicles.

Problems solved by technology

However, due to the limitation of battery technology at the current stage, the cruising range of electric vehicles is still difficult to meet the needs of consumers. Short cruising range, few charging devices, and long waiting time have become the primary problems in the promotion of electric vehicles.

In order to solve the problem of charging and short mileage, many technical solutions for charging electric vehicles while driving have emerged. Chinese patent (CN106945565A) discloses a wireless charging device for driving a car, which uses a non-contact wireless charging method, but The wireless charging method has low charging efficiency, slow speed, and high cost; Chinese patent (CN104859463A) discloses a charging device and charging method for electric vehicles during driving. Putting up a pick-up pole, due to the low height of the family car, will require a higher pick-up pole, which will not only affect the stability when driving, but also need to drive along the contact line, which is difficult to achieve under complex road conditions ; Chinese patent (CN102275513A) discloses a kind of electricity consumption and the charging method of taking electricity from the ground during driving of electric vehicle, stretches out the electricity taking device at the bottom of the car and snaps into the groove designed on the driveway to take electricity, same, The driving of the vehicle will be restricted by the groove, and the driving of the vehicle in the lane is limited. It cannot meet the operations of changing lanes and overtaking on ordinary roads. It needs to drive in sequence on the designated road sections, and the actual feasibility is not strong.
