Energy conversion device and vehicle

Abstract

The invention provides an energy conversion device and a vehicle, the energy conversion device comprises a reversible PWM rectifier, a motor coil and a switch module, the motor coil comprises a firstwinding unit and a second winding unit, and an external battery, the reversible PWM rectifier and the motor coil form a driving loop or a heating loop. An external direct-current port and an externalbattery form a direct-current charging circuit or a direct-current discharging circuit through the energy conversion device, a motor is driven by the driving loop to output power or heating power, andthe direct-current discharging circuit or the direct-current charging circuit is used for discharging to the outside or receiving charging to. And the reversible PWM rectifier and the motor are adopted in the driving circuit, the heating circuit, the direct-current charging circuit and the direct-current discharging circuit, so that the circuit structure is simplified, the integration degree is improved, and the purposes of reducing the size and reducing the cost are achieved.

Description

Technical field[0001]The present application relates to the technical field of vehicle, and more particularly to an energy conversion device and a vehicle.Background technique[0002]With the continuous spread of electric vehicles, more and more electric vehicles will enter society and families, bringing great convenience to people's travel, and the relevant subsidy policies of the construction of the charging stations across the land are also planning and even introduced, charging infrastructure regardless of It is quantified to have a big increase in the distribution. However, due to the limitations of the renewal mileage of the pure electric vehicle, the vehicle user is very concerned about the problem of the vehicle due to the power supply of the power supply. Although many vehicle manufacturing companies have reminded the vehicle driver's battery residual power information and the electricity of the vehicle, it is inevitable that the vehicle remaining power cannot meet the vehicl...

Problems solved by technology

However, due to the limitation of the driving range of pure electric vehicles, vehicle users are very concerned about the problem that the vehicle breaks down due to the exhaustion of the power source.

Although many vehicle manufacturers remind the vehicle driver of the remaining battery power information and low battery warning information through the vehicle instrument or other methods, it is inevitable that the remaining power of the vehicle cannot meet the needs of the vehicle to drive to the location of the charging facility or the driver unconsciously When the vehicle is depleted

[0003] In order to avoid this problem from affecting the experience of vehicle users on the use of pure electric vehicles, and even affect the use and promotion of pure electric vehicles, it is necessary to develop mobile power supply equipment to charge the vehicle to meet the needs of the vehicle when the battery is exhausted or the battery is low. The need for supplementary electric energy to the vehicle when the energy storage device is no longer output
