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 and a motor coil, the motor coil comprises at least two sets of winding units, each set of winding is connected with the reversible PWM rectifier, and an external first direct current port and an external battery form a direct current charging circuit or a direct current discharging circuit through the energy conversion device; an external battery, the reversible PWM rectifier in the energy conversion device and the motor coil form a driving circuit; the driving circuit drives the motor to output power, and the direct-current discharging circuit or the direct-current charging circuit is used for discharging or receiving charging to the outside so that chargingof direct-current power supply equipment is received when the electric quantity of the external battery is insufficient, and discharging to direct-current electric equipment is realized when the electric quantity of the external battery is sufficient.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to an energy conversion device and a vehicle. Background technique [0002] With the continuous popularization of electric vehicles, more and more electric vehicles will enter society and families, bringing great convenience to people's travel. Relevant subsidy policies for the construction of charging stations in various places are also planned or even introduced. Both the quantity and the distribution range have been greatly improved. However, due to the limitation of the mileage 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...

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 charging 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
