[0078] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0079] Electric vehicles are equipped with many electrical devices. During use, these devices are typically powered by the vehicle's power battery. When the power battery is low, it can be recharged using a charging device, such as a charging station. However, once connected to the vehicle, the charging device generally only charges the vehicle's power battery and does not provide power to the vehicle's electrical devices. This results in limited application scenarios for the combination of vehicle and charging device, and inflexible utilization of the charging device's power energy.

[0080] Therefore, a vehicle is needed so that the charging device can supply power to the electrical devices in the vehicle before charging the power battery of the vehicle, thereby expanding the application scenarios of the combination of the vehicle and the charging device.

[0081] According to the vehicle disclosed in the embodiment of the present application, the charging device can supply power to the electrical devices in the vehicle before charging.

[0082] Figure 1 is an exemplary structural block diagram of a vehicle according to some embodiments of the present application. Figure 2 is an exemplary schematic diagram of a vehicle according to some embodiments of the present application. Figures 3-21 are exemplary schematic diagrams of vehicles according to some embodiments of the present application. For ease of explanation, the description will be combined with one or more of Figures 1-21.

[0083] 1 , an embodiment of the present application provides a vehicle 100 , comprising: a power battery 110 ; an electrical device 120 ; a charging interface 130 , configured to connect to a charging device 150 so that the vehicle 100 can be powered by the charging device 150 , the charging interface 130 comprising a positive terminal and a negative terminal; and a bypass module 140 , configured to connect or disconnect the charging device 150 from the electrical device 120 .

[0084] As used herein, the term "charging device" may include an off-board conductive charger (hereinafter referred to as an off-board charger or simply a charger). The charging device 150 can be used to power the power battery 110 and / or the powered device 120. In related art, after the vehicle 100 is connected to the charging device 150 via the charging port 130 , the power battery 110 of the vehicle 100 can be electrically connected to the charging device 150, at which point the power battery 110 can serve as a load for the charging device 150.

[0085] As used herein, the term "bypass module" refers to a device that can control the electrical connection between the power-consuming device 120 and the charging device 150. In some embodiments, when the bypass module 140 is turned on, the power-consuming device 120 can be electrically connected to the charging device 150 via the charging port 130 , and the power-consuming device 120 can then serve as a load for the charging device 150.

[0086] The bypass module 140 is installed in the vehicle to connect or disconnect the power consumption device 120 in the vehicle 100 from the charging device 150. The charging device 150 can supply power to the power consumption device 120 based on usage needs. When power supply from the charging device 150 to the power consumption device 120 is no longer needed, the electrical connection between the charging device 150 and the power consumption device 120 can be disconnected. This allows the charging device 150 to supply power to the power consumption device 1120 before charging the power battery, thereby expanding the application scenarios of the vehicle 100 and the charging device 150 and enabling flexible utilization of the power energy of the charging device 150.

[0087] In certain application scenarios, this further provides additional benefits. For example, when the state of the power battery 110 does not allow charging (for example, the temperature is too low), some additional operations (for example, electric heating) may be required to enable the power battery 110 to meet the charging conditions. These additional operations may cause current or voltage fluctuations in the charging circuit, thereby damaging the charging device 150 or even the power grid. By electrically connecting the charging device 150 to the power device 120 (and potentially disconnecting the electrical connection between the charging device 150 and the power battery 110), these additional operations (for example, electric heating) can be completed without damaging the charging device 150 while maintaining the physical connection between the vehicle 100 and the charging device 150.

In some embodiments, referring to Figures 2-17 , the bypass module 140 may include two switches, one switch, a switch and a wire, or a wire. Any arrangement that utilizes switches and / or wires to electrically connect and disconnect the powered device 120 from the charging device 150 is possible and is not intended to be limiting.

[0094] According to some embodiments of the present application, the bypass module 140 may include: a first switch connected between the positive terminal and the positive line of the electrical device 120; and a second wire connected between the negative terminal and the negative line of the electrical device 120.

[0117] When the temperature is low, the power battery 110 cannot be charged because it is too cold. In this case, the power module 160 can be used to heat the power battery 110. After the electrical connection between the power battery 110 and the charging device 150 is disconnected, the power module 160 can be used to apply current to the power battery 110. Due to the internal resistance of the power battery 110, when current flows through the power battery 110, heat is generated, thereby heating the power battery 110.

[0118] The fifth switch may be a switch K3 connected between the positive electrode of the power battery 110 and the positive line of the power module 160 , and the sixth switch may be a switch K4 connected between the negative electrode of the power battery 110 and the negative line of the power module 160 .

The power module 160 applies current to both sides of the power battery 110, causing the battery's internal resistance to rapidly heat the battery.

[0126] After the above-mentioned charging self-heating process is completed (i.e., the charging device 150 is in the heating-ready state), the fifth switch K3 and the sixth switch K4, as well as the first switch K12 and the second switch K13 are opened, and the seventh switch K5 and the eighth switch K6 are closed, so that the power battery 110 and the charging device 150 are electrically connected, and the charging device 150 transmits energy to the power battery 110.
