Abstract

The invention provides a vehicle-mounted charging and discharging device. The vehicle-mounted charging and discharging device comprises an alternating current-direct current converter, a direct current converter, a first switch module and a second switch module; the alternating current-direct current converter is connected in series with the direct current converter, an AC end of the alternating current-direct current converter is connected with an AC charging port, and a DC end of the alternating current-direct current converter is connected with a first end of the first switch module. One end of the direct current converter is connected with the first end of the first switch module, and the other end is connected with the second end of the second switch module and a battery pack. The second end of the first switch module is connected with the direct current charging port. The first end of the second switch module is connected with the direct current charging port. According to the vehicle-mounted charging and discharging device, the new energy vehicle with the vehicle-mounted charging and discharging device can be suitable for the charging pile with the highest voltage of 500v, 750v and even 1000v, and then the market competitiveness of the new energy vehicle is enhanced.

Description

technical field [0001] The present application relates to the technical field of smart cars, and specifically relates to a vehicle-mounted charging and discharging device, a charging and discharging method, a smart car, and a readable storage medium. Background technique [0002] With the continuous development of new energy vehicle technology, many new energy vehicles on the market integrate on-board chargers, on-board power supply high-voltage to 14V voltage converters, and on-board power distribution boxes, named as three-in-one on-board power supply. It can improve the system integration of new energy vehicles. [0003] When the charging pile is an AC charging pile, the three-in-one vehicle power supply converts the AC into a DC to charge the battery pack. When the charging pile is a DC charging pile, the DC charging pile outputs DC to directly charge the battery pack through the three-in-one vehicle power supply. [0004] However, the applicant found that most of the ...
