Embodiment 1

[0025] This embodiment discloses a range-extending system for an electric vehicle, including: a range-extending module, an exhaust gas diversion module, and a power management module. The range-extending module includes a variety of range extenders, and the range extender provides additional power support for the electric vehicle , the top of the electric vehicle is provided with a docking station, the docking station is used to connect the battery and the motor of the range extender and the electric vehicle, the electric energy sent by the range extender drives the motor to rotate through the docking station or charges the battery, the exhaust gas The drainage module includes a heat flow pipe that introduces the high-temperature exhaust gas of the range extender into the battery storage box of the electric vehicle and the radiator in the car. The range extender control module controls the working mode of the range extender and monitors the parameter status of the range extender...

Embodiment 2

[0035] This embodiment discloses a range extender system for an electric vehicle. An external wire-type range extender is used. A telescopic pantograph is installed on the top of the electric vehicle. The pantograph is in contact with the charging line erected on the road. Fast charging of electric vehicle batteries.

[0036] A retractable pantograph is installed on the top of the electric vehicle. When the battery of the electric vehicle needs to be charged, the range extender control module controls the external cable type range extender to raise the pantograph, contact with the wires erected above the road, and pass through the pantograph. The electric energy is drawn out, and the alternating current is converted into direct current through the rectification device. The fast charging interface 7 of the docking station is connected to the pantograph, and the fast charging interface 7 is connected to the battery charging interface and the main power line, so as to charge the b...

Embodiment 3

[0038] This embodiment discloses a range extender system for an electric vehicle, which adopts a battery exchange type range extender, an auxiliary battery is installed on the roof of the electric vehicle, the auxiliary battery is connected to the docking station, and the auxiliary battery The battery is connected to the main power line to drive the electric vehicle. The auxiliary battery can be charged independently. The auxiliary battery generally adopts the eliminated battery with reduced power storage capacity to improve the reutilization rate of the eliminated battery and increase the battery life of the electric vehicle.

Abstract

The invention discloses a range extender system of an electric automobile. The range extender system of the electric automobile comprises a range extender module, a tail gas drainage module and a range extender control module, wherein the range extender module comprises a plurality of range extender, the range extenders provide additional power support for the electric automobile, docking stationsare arranged at the top of the electric automobile, and the expansion docks are used for being connected with the range extenders and a battery of the electric automobile and a motor, and electric energy emitted by the range extenders drives the motor to rotate or charge the battery through the expansion dock driving motor; and the tail gas drainage module comprises a heat flow pipeline, the heatflow pipeline introduces high-temperature tail gas of the range extenders into a battery containing box of the electric automobile and a radiator in the automobile, the range extender control moduleis used for controlling the working mode of the range extender and monitoring the parameter state of the range extenders. According to the automobile range extender system, the problem of poor cruising ability of an existing electric automobile is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electric vehicle accessories, and in particular to a range-extending system for electric vehicles. Background technique [0002] At this stage, there are two constraints on the promotion of electric vehicles. The first is the mileage of the vehicle, and the second is the cost of the vehicle. There are two aspects to the problem of vehicle cruising range. (1) During daily use in winter, the cruising range of the vehicle is greatly shortened due to the decrease in battery activity, and the thermal stability system of the vehicle battery pack relies on the power consumed by the battery to generate heat, so even if the battery is upgraded activity, but has little effect on the battery life of electric vehicles. (2) The mileage of long-distance running is insufficient. At this stage, the development of public charging systems is not perfect. Although charging piles are installed on some expressway...
