摘要: A charger, a soft-start method, an electric vehicle, and a charging system are disclosed. The charger includes a control module, a DC-DC conversion circuit, and a first capacitor. When the electric vehicle is charged, the control module in the charger may first control the DC-DC conversion circuit to charge the first capacitor by using battery electric energy output by a battery system, and after determining that a capacitance voltage of the first capacitor reaches a first threshold voltage, indicate a charging pile to output charging electric energy. A soft-start circuit does not need to be disposed in a soft-start process of the charger, which helps simplify a circuit of the charger and implement a miniaturization design of the charger.

摘要: According to one aspect of the present disclosure, there is provided an apparatus that includes a battery, a Direct Current (DC) bus connected to the battery, and a DC to DC converter connected to the battery in parallel with the DC bus. A Motor Control Unit (MCU) is connected between the DC to DC converter and an electric motor. An Alternating Current (AC) port is connected to the electric motor. Switches connect the DC bus and an output of the DC to DC converter in series as an input to the MCU in a drive mode and disconnect the DC bus from the MCU in a charge mode.

摘要: A charging and discharging circuit and system, and an electric vehicle are provided. The charging and discharging circuit includes a battery (1), a motor (5), a first charging interface (6), a first bridge arm (2), a second bridge arm (3), a third bridge arm (4), a first switch (K1), a second switch (K2), a third switch (K3), a fourth switch (K4), a fifth switch (SI), a sixth switch (S2), a seventh switch (S3), and an eighth switch (S4). In the structure, the charging and discharging circuit can implement a driving mode and a charging mode. Therefore, an unnecessary component in the charging and discharging circuit is omitted, thereby reducing a volume of the charging and discharging circuit.
