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

Embodiment approach

[0048] As a first embodiment, when the external charging and discharging port 104 is connected to a DC power supply device, the DC power supply device forms a first DC power supply with the external battery 101 through the first reversible PWM rectifier 102 and the first motor coil 103 in the energy conversion device. charging circuit;

[0049] The DC power supply equipment forms a second DC charging circuit with the external battery 101 through the second reversible PWM rectifier 105 and the second motor coil 106 in the energy conversion device;

[0050] The energy conversion device selects the first DC charging circuit or the second DC charging circuit to work according to the external control signal.

[0051] Wherein, in the DC charging mode, the external charge and discharge port 104 is connected to the DC power supply equipment, and the DC power supply equipment forms a first DC power supply with the external battery 101 through the first reversible PWM rectifier 102 and ...

Abstract

The invention provides an energy conversion device and a vehicle. The energy conversion device comprises a first reversible PWM rectifier, a second reversible PWM rectifier, a first motor coil and a second motor coil, and an external charging and discharging port and an external battery form a DC charging circuit or a DC discharging circuit through the energy conversion device. An external battery, the first reversible PWM rectifier and the first motor coil in the energy conversion device form a first driving loop, and the external battery, the second reversible PWM rectifier and the second motor coil in the energy conversion device form a second driving loop; the reversible PWM rectifiers and the motor are adopted in the driving circuit, the DC charging circuit and the DC 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 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...
