When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first", "second", etc. involved in the embodiments of this application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0027] Next, the embodiments of this application will be described in detail.

[0028] Such as Figure 1As shown in the figure, the present application provides a power management system for a motorhome, including a vehicle controller 10, a motorhome power controller 20, a power battery pack 30, an electrical load 40, and a gateway 50.

[0029] The vehicle controller 10 is used to control the management of high-voltage start-up, driving, AC / DC charging, range extender power generation and other working conditions of the motorhome, as well as the three-level fault protection management of the vehicle system. The vehicle controller 10 is communicatively connected to the power battery pack 30 and can send control signals to the power battery pack 30.

[0030] The electrical load 40 is arranged in the living compartment of the motorhome. The motorhome power controller 20 is connected to the electrical load 40 and is used to control the power distribution and power management of the electrical load 40, etc. The power battery pack 30 is connected to the electrical load 40 and can supply power to the electrical load 40.

[0031] It should be noted that the motorhome of the present application uses a new energy light truck as the design platform and can use its own power battery pack 30 as the power supply source for each electrical load 40 in the living compartment of the motorhome. During the modification of the motorhome, there is no need to additionally install other power generation equipment (such as gasoline / diesel generators, photovoltaic solar panels, and heavy-duty lithium battery packs), which effectively releases the space in the living compartment of the motorhome, simplifies the modification process, reduces the modification and maintenance costs of the motorhome, and is beneficial to the lightweight design of the motorhome.

[0032] The vehicle controller 10 is connected to the motorhome power controller 20 through the gateway 50 to incorporate the living compartment network into the vehicle network, realizing the interconnection of the living compartment network and the vehicle network of the motorhome, facilitating the user to timely understand and control the working state of the motorhome power management system, and being beneficial to the intelligent and efficient management of the motorhome power management system.

[0033] Furthermore, the power management system for the motorhome of the present application further includes a high-voltage auxiliary drive 60. The high-voltage auxiliary drive 60 is communicatively connected to the vehicle controller 10, and the vehicle controller 10 can transmit control signals to the high-voltage auxiliary drive 60 to control it. The power battery pack 30 is connected to the electrical load 40 through the high-voltage auxiliary drive 60.

[0034] The high-voltage auxiliary drive 60 includes a power distribution module 61, a first inverter module 62, a DC-DC converter 63, a generator controller 64, and an on-vehicle charger 65. The first inverter module 62, the DC-DC converter 63, the generator controller 64, and the on-vehicle charger 65 are all connected to the power distribution module 61 through contactors or relays.

[0035] The power distribution module 61 is connected to the power battery pack 30 to distribute the power from the power battery pack 30 to each module of the high-voltage auxiliary drive 60. By controlling the opening and closing of the contactors and relays, reasonable power distribution and management of each module of the high-voltage auxiliary drive 60 can be achieved. Specifically, Figure 1In the illustrated embodiment, the power distribution module 61 is a PDU (Power Distribution Unit).

[0036] The first inverter module 62 is connected to the electrical load 40 and can invert the 600V high-voltage direct current of the power battery pack 30 into 200V alternating current for supply to the electrical load 40. Figure 1 In the illustrated embodiment, the first inverter module 62 is a DC / AC (7kW). A controllable circuit breaker 93 is provided between the first inverter module 62 and the electrical load 40, which can control the on / off of the line between the first inverter module 62 and the electrical load 40.

[0037] Furthermore, the RV power management system further includes a low-voltage battery 70 and a range extender 80. The DC / DC converter 63 is connected to the low-voltage battery 70 and can convert the 600V high-voltage direct current of the power battery pack 30 into 27.5V low-voltage direct current to charge the low-voltage battery 70. The DC / DC converter 63 is Figure 1 shown as DCDC in. The range extender 80 is connected to the generator controller 64 and can provide electrical energy for the power battery pack 30 under the control of the generator controller 64.

[0038] Furthermore, the RV power management system further includes an AC charging interface 91 and a DC charging interface 92. The AC charging interface 91 is connected to the on-vehicle charger 65. When there is a power socket configuration of 220V - 16A or above in the surrounding environment of the RV, the on-vehicle charger 65 monitors signals such as CC and CP of the AC charging interface 91 and can enter the AC charging process to achieve AC charging of the power battery pack 30.

[0039] The on-vehicle charger 65 of the present application has a bidirectional inversion function. It can not only receive external electrical energy but also, when a discharge device is externally connected to the AC charging interface 91, invert the direct current in the power battery pack 30 into alternating current to provide 3kW of 220V AC power for the external device. In this way, outdoor power consumption of the RV in scenarios such as camping sites can be achieved.

[0040] The DC charging interface 92 is connected to the power distribution module 61. When there is a DC charging pile configuration in the surrounding environment of the RV, the power battery system monitors signals such as CC1, CC2, and PE of the DC charging interface 92 and can enter the DC charging process to charge the power battery pack 30 directly.

[0041] The RV power management system of the present application further includes a backup battery pack 21, a second inverter module 22, an emergency power actuator 23, and a load power distribution execution unit 24. The backup battery pack 21, the second inverter module 22, the emergency power actuator 23, and the load power distribution execution unit 24 are all in communication with the RV power controller 20 and can receive control signals from the RV power controller 20.

[0042] The backup battery pack 21 is connected to the electrical load 40 via the second inverter module 22 and can provide power to the electrical load 40 . Figure 1 In the illustrated embodiment, the second inverter module 22 is a DC / AC (3kW) inverter module that converts the high-voltage DC power from the backup battery pack 21 into AC power and supplies it to the power load 40. A controllable circuit breaker 93 is provided between the second inverter module 22 and the power load 40 to control the connection between the second inverter module 22 and the power load 40.

[0043] In this embodiment, the backup battery pack 21 is a lithium battery. Its volume and storage capacity can be flexibly designed according to the needs of the RV to meet the RV's requirements for large space and lightweight. In some cases, the backup battery pack 21 can also be a lead-acid battery, etc., which is not limited in this application.

[0044] The emergency power actuator 23 is connected to the DC converter 63 and the backup battery pack 21. When the emergency power actuator 23 is closed, the path between the power battery pack 30 and the backup battery pack 21 is connected, and the power battery pack 30 replenishes the backup battery pack 21.

[0045] Specifically, a first node N1 is provided between the DC converter 63 and the low-voltage battery 70, and the emergency power actuator 23 is connected to the first node N1. Thus, when the emergency power actuator 23 is closed, the path between the low-voltage battery 70 and the backup battery pack 21 is connected, enabling the backup battery pack 21 to jumper the low-voltage battery 70.

[0046] A second node N2 is provided between the backup battery pack 21 and the second inverter module 22, and the emergency power actuator 23 is connected to the first node N2. Thus, when the emergency power actuator 23 is closed, power from the power battery pack 30 can be directly transmitted to the electrical load 40 via the second inverter module 22, thereby providing power to the electrical load 40.

[0047] The opening and closing of the emergency power actuator 23 can be controlled by a signal from the RV power controller 20 or manually by the user.

[0048] The electrical load 40 includes all the equipment and systems in the living compartment of the RV that require electricity, such as high-power equipment like kitchen and bathroom appliances, air-conditioning systems, and low-power equipment like lighting and entertainment appliances. The RV power controller 20, the power battery pack 30, and the backup battery pack 21 are all connected to the electrical load 40 through the load power distribution execution unit 24. The load power distribution execution unit 24 can reasonably distribute and manage the electricity flowing to different electrical loads 40.

[0049] The RV power management system of the present application sets the power battery pack 30 and the backup battery pack 21 as the energy sources for the electrical load 40 in the living compartment of the RV. The power battery pack 30 can charge the backup battery pack 21. At the same time, an extender 80, an AC charging interface 91, a DC charging interface 92, etc. are set to achieve multi-channel charging for the power battery pack 30, so that the RV power management system can provide sufficient electricity for the electrical load 40, and users do not need to face electricity problems, improving the use comfort and versatility of the RV.

[0050] In addition, since the range-extended new energy light truck itself has components such as the power battery pack 30, the high-voltage auxiliary drive 60, the extender 80, the AC charging interface 91, and the DC charging interface 92, when using the range-extended new energy light truck as a design platform to install a living compartment on the RV, the above-mentioned original components can be used to effectively manage the RV power, so as to expand the living compartment space and reduce the modification cost.

[0051] The RV power management system of the present application has the following working modes: driving mode, parking mode, night mode, and emergency mode. The RV power management under each working mode will be described below.

[0052] In the driving mode, after the vehicle key is powered on, the vehicle controller 10 controls the high-voltage auxiliary drive 60, the power battery pack 30, the electric drive system, etc. to complete the high-voltage operation to make the vehicle drive normally. At this time, the DC converter 63 converts the high-voltage direct current of the power battery pack 30 into low-voltage direct current to charge the low-voltage battery 70. The RV power controller 20 controls the second inverter module 22 to work, and the backup battery pack 21 supplies power to the electrical load 40 through the second inverter module 22 to maintain the electricity demand of the living compartment during the driving process of the vehicle.

[0053] The RV power controller 20 monitors the state of the backup battery pack 21. When the power of the backup battery pack 21 is lower than the first threshold, the RV power controller 20 controls the emergency power actuator 23 to close, and the power battery pack 30 charges the backup battery pack 21 through the DC converter 63, while also taking into account the charging of the low-voltage battery 70. When the power of the backup battery pack 21 is higher than the second threshold, the RV power controller 20 controls the emergency power actuator 23 to disconnect and stops charging the backup battery pack 21.

[0054] The first threshold and the second threshold can be flexibly set according to actual needs. Preferably, to ensure that the standby battery pack 21 is always in a high power state, the first threshold is 80% of the total capacity of the standby battery pack 21, and the second threshold is 95% of the total capacity of the standby battery pack 21.

[0055] In the parking mode, the RV power controller 20 controls the second inverter module 22 to stop working, and transmits the parking mode requirement to the vehicle controller 10 through the gateway 50. The vehicle controller 10 controls the first inverter module 62 to start working, and the power battery pack 30 supplies power to the electrical load 40 through the first inverter module 62.

[0056] When there is a power socket configuration of more than 220V - 16A in the surrounding environment, the on-vehicle charger 65 monitors signals such as CC and CP of the AC charging interface 91, enters the AC charging process, realizes the charging of the power battery pack 30, and at the same time, the branch power output of the first inverter module 62 meets the power consumption requirements of the electrical load 40 in the parking state.

[0057] When there is no power socket configuration of more than 220V - 16A in the surrounding environment and there is a DC charging pile configuration, the power battery system monitors signals such as CC1, CC2, and PE of the DC charging interface 92, enters the DC charging process, charges the power battery pack 30 with DC power, and at the same time, the branch power output of the first inverter module 62 meets the power consumption requirements of the electrical load 40 in the parking state.

[0058] The vehicle controller 10 monitors the state of the power battery pack 30. When no external power is introduced, when the power of the power battery pack 30 is lower than the third threshold, the vehicle controller 10 controls the range extender 80 to generate electricity to charge the power battery pack 30, and at the same time, the branch power output of the first inverter module 62 meets the power consumption requirements of the electrical load 40 in the parking state. When the power of the power battery pack 30 is higher than the fourth threshold, the vehicle controller 10 controls the range extender 80 to stop generating electricity.

[0059] The third threshold and the fourth threshold can be flexibly set according to actual needs. To ensure that the power of the power battery pack 30 is in a relatively reasonable state, the third threshold is not lower than 15% of the total capacity of the power battery pack 30, and the fourth threshold is not lower than 95% of the total capacity of the power battery pack 30. Preferably, the third threshold is 25% of the total capacity of the power battery pack 30, and the fourth threshold is 85% of the total capacity of the power battery pack 30.

[0060] In the parking mode, the bidirectional inverter function of the on-vehicle charger 65 can also be used to connect a discharging device to the AC charging interface 91 to meet the outdoor power consumption requirements.

[0061] After the vehicle is powered off and the power flow of the power battery pack 30 is cut off, when the electrical load 40 still has an electricity demand, the night mode can be selected. In the night mode, the RV power supply controller 20 controls the second inverter module 22 to work, and the backup battery pack 21 supplies power to the electrical load 40 through the second inverter module 22 to maintain the electricity demand of the living compartment of the vehicle in the night mode.

[0062] When there is a three-level fault in the power battery pack 30 or other three-level faults in the whole vehicle, the whole vehicle cannot be powered on at high voltage, and the power of the power battery pack 30 cannot be transmitted to the electrical load 40. The emergency mode can be selected. In the emergency mode, the RV power supply controller 20 controls the second inverter module 22 to work, and the backup battery pack 21 supplies power to the electrical load 40 through the second inverter module 22 to meet the electricity demand of the user when waiting for rescue. At the same time, the RV power supply controller 20 controls the emergency power actuator 23 to close, and the backup battery pack 21 can charge the low-voltage battery 70 to prevent the vehicle from failing to start due to the discharge of the low-voltage battery 70.

[0063] The RV power supply management system of the present application ensures the effective utilization of the RV power resources by setting different working modes and allowing the selection and switching of working modes according to different usage scenarios of the RV. Moreover, it can provide reliable power support in case of emergencies, improving the comfort and safety of RV use.

[0064] As Figure 2 shown, the RV power supply management system of the present application further includes a CAN bus 51, an in-vehicle terminal 52 and a car machine 53. The vehicle controller 10, the RV power supply controller 20, the in-vehicle terminal 52 and the car machine 53 are all connected to the gateway 50 through the CAN bus 51 to realize the signal association between the vehicle network and the living compartment network.

[0065] Specifically, the CAN bus 51 includes EVCAN, PTCAN, BCAN, TCAN under the vehicle network and LCAN under the living compartment network.

[0066] The vehicle controller 10, the high-voltage auxiliary drive 60, the power battery system and the MCU (Motor Control Unit) are communicatively connected to the gateway 50 through the EVCAN. The EGSM (Electronic Gear Shift Module) and the range extender 80 are communicatively connected to the gateway 50 through the PTCAN. The instrument, the BCM (Body Control Module) and the car machine 53 are communicatively connected to the gateway 50 through the BCAN. The VDR (Vehicle Data Recorder) and the in-vehicle terminal 52 (Telematics Box, Figure 2The one shown as the T-Box in the figure is communicatively connected to the gateway 50 through TCAN. The mobile phone APP can synchronize data with and interact with the vehicle-mounted terminal 52 through the cloud to achieve remote monitoring, management, and services of the vehicle on the mobile phone side. The RV power controller 20, the backup battery pack 21, and the second inverter module 22 are communicatively connected to the gateway 50 through LCAN.

[0067] The RV power controller 20 is connected to the gateway 50 through the CAN bus 51, realizing the signal association between the vehicle's entire network and the living compartment network. Through the associated communication of "mobile phone APP - vehicle-mounted terminal 52 - gateway 50 - RV power controller 20", the user can set different working modes of the RV power management system on the mobile phone side, and the user can also timely understand and control the working and fault states of the backup battery pack 21 and the second inverter module 22 on the mobile phone side. Through the association of "in-vehicle computer 53 - gateway 50 - RV power controller 20", the user can also set different working modes of the RV power management system on the in-vehicle computer 53 side, improving the human-machine interaction.

[0068] This application also provides an RV, including the above-described RV power management system.

[0069] The power battery pack 30 of the RV power management system and the electrical load 40 proposed in this application are connected, and the power battery pack 30 can supply power to the electrical load 40 without the need to additionally install other power generation devices, saving the vehicle interior space and reducing the weight, modification, and maintenance costs of the RV. At the same time, by connecting the RV power controller 20 that controls the electrical load 40 and the vehicle's entire controller 10 that controls the power battery pack 30 through the gateway 50, signal association is achieved, facilitating intelligent and efficient management of the RV power.
