Abstract

The utility model discloses a charging/discharging control system of an electric vehicle and an electric vehicle. The system comprises a converting device, a switch device and a control device, wherein the converting device is used for converting a direct current output from a battery into an alternative current during discharging of the electric vehicle, and for converting an alternative current output from a power grid into a direct current during charging of the battery; the switch device comprises a first switch and a second switch, wherein the first switch is connected between the battery and the converting device, and the second switch is connected between the converting device and the power grid; and the control device is used for controlling the converting device to work and controlling the opening and closing of the switch device. With the technical scheme, the charging to the battery of the electric vehicle at low electricity use demand and the electricity supply to the power grid by converting the direct current into a single phase, a two phase and a three phase electricity source through the battery embedded in the vehicle at high electricity use demand are released, so that the use cost of the vehicle is reduced.

Description

The charge-discharge control system of motor vehicle and electric motor car
Technical field
The utility model relates to a kind of charge-discharge control system and electric motor car of motor vehicle.
Background technology
Along with development of science and technology; The electric automobile of environmental protection and energy saving is being played the part of the role who replaces fuel vehicle; Yet universal some problems that also are faced with of electric automobile; Wherein high-energy-density, safe and reliable battery, low cost, small size, safe and reliable vehicle-mounted quick charge device become the subject matter that industry is concerned about gradually.Behind the battery of designing big capacity high-energy-density, the subject matter that electric automobile faces just forwards on the charging problem.
For jumbo battery; Can improve the electronic flying power of electric automobile; But same jumbo battery has brought long problem of charging interval again; Though charging station can be fast for battery charges, the cost of great number and bigger problems such as floor space make popularizing of this infrastructure also be faced with certain degree of difficulty.
Connect rectification circuit after general onboard charger adopts isolation method, carry out vehicle-mounted charge through small-power high-frequency isolation DC/DC again.But this mode charge power is little, and the charging interval is long, and the hardware volume is bigger, function singleness, and be subject to the electric pressure restriction of different electrical networks, most chargers can only be applicable to the commercial electrical network of single appointment.
In addition, because the fast development that industrial or agricultural is built and the raising of living standards of the people, the demand of electric power is also grown with each passing day particularly electricity consumption peak period.Though national huge fund has been built many big small-scale power stations, but still can't satisfy the active demand that electric load increases.
Thereby, a kind of system that can alleviate power shortage need be provided.
The utility model content
The purpose of the utility model provides a kind of charge-discharge control system and electric motor car of motor vehicle, to solve above-mentioned the problems of the prior art.
To achieve these goals; The utility model provides a kind of charge-discharge control system of motor vehicle; Comprise: converting means; The direct current that is used for when the battery discharge of motor vehicle, battery being exported converts alternating current into, and the alternating current of to battery charge the time, electrical network being exported converts direct current into; Switching device; Comprise first switch and second switch; First switch is connected between battery and the said converting means, and second switch is connected control device between converting means and the said electrical network, is used for the disconnection and the closure of work of control change device and control switch device.
The utility model also provides a kind of electric motor car, comprises the charge-discharge control system of motor and above-mentioned motor vehicle.
Use control device that power-converting device, switching device are controlled through technique scheme; Not only realized when the electricity consumption ebb charging to batteries of electric automobile; Can also be when peak of power consumption through the built-in battery of automobile with direct current through changing into single-phase, two-phase and three-phase power source to mains supply, thereby reduced the use cost of automobile.
Other feature and advantage of the utility model will partly specify in embodiment subsequently.
