Energy conversion device and vehicle

Abstract

The present application proposes an energy conversion device and a vehicle. The energy conversion device includes a reversible PWM rectifier, a motor coil, and a first capacitor module. The motor coil includes a first winding unit and a second winding unit respectively connected to the reversible PWM rectifier. The first The winding unit is connected to the first terminal of the external battery, the second winding unit is connected to the first terminal of the external first DC port, and the first terminal of the first capacitor module is connected to the first bus terminal of the reversible PWM rectifier, reversible The second bus terminal of the PWM rectifier is respectively connected to the second terminal of the first capacitor module, the second terminal of the first DC port, and the second terminal of the battery. When the device is used for charging, discharging and driving, the reversible PWM rectifier and motor coil are reused, which not only simplifies the circuit structure, improves the integration level, achieves the purpose of reducing the volume and cost, but also solves the problem of existing battery charging circuits and The overall control circuit of the motor drive circuit has complex structure, low integration, large volume and high cost.

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 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 v...

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
