[0049] Each power distribution unit smart socket is installed at a specific location on the all-terrain vehicle and provides multiple power sockets so that various devices can be connected and powered and controlled by the PDU.

[0050] In order to monitor and control power usage, each power distribution unit smart socket is connected to the power distribution unit power control MCU through a 485 communication interface. Each power distribution unit smart socket is equipped with a power switch button for manually controlling the power on and off of the device at each location.

[0051] The power distribution unit power central control MCU communicates with the vehicle controller VCU through the CAN bus to provide the vehicle controller VCU with data on the total current, voltage and power consumption of each device point (PDU location).

[0052] In another exemplary embodiment of the present application, the external charging module includes but is not limited to: a solar panel, a charging pile, and a mains socket;

[0053] Solar panels are used to collect solar energy and convert it into electrical energy to provide energy supplement for all-terrain vehicles in emergency environments; charging piles provide external AC power; the AC power socket is a backup charging interface when the all-terrain vehicle is parked in a AC power area; this application introduces multiple energy access methods such as solar panels and charging piles, which not only enables the vehicle to obtain self-sufficient energy supply outdoors or in emergency situations, but also allows convenient charging when AC power is available, thereby improving the flexibility and sustainability of energy utilization.

[0054] The solar panel is connected to the on-board charging module OBCM through the MC4 photovoltaic conversion connector to XT60, providing 12VDC, 24VDC, and 48VDC DC power supply;

[0055] The charging pile is connected to the on-board charging module OBCM through a standard charging interface to supply 220VAC AC power; the standard charging interface includes: GB / T;

[0056] The AC power socket is directly connected to the on-board charging module OBCM to supply 220VAC AC power.

[0057] The on-board charging module OBCM converts electrical energy from different sources (solar panels, charging piles, mains sockets) into direct current suitable for battery charging.

[0058] Receive input from solar panels, charging piles, mains sockets, etc., and output DC power to charge the battery (such as 72V) through the internal electronic conversion device. Connect directly to the battery and monitor the charging process through the battery management system BMS.

[0059] The battery stores electrical energy obtained from various power sources and provides power for the ATV. The battery is a key component in the ATV modular equipment access system, responsible for storing electrical energy from various power sources and providing power for the ATV. The battery in this application provides high voltage DC (usually 72V) with enough electrical energy to drive various electric systems and modular equipment of the electric vehicle.

[0060] The battery management system (BMS) monitors and manages the battery charging and discharging process to ensure safety and performance; the monitoring strategies of the battery management system (BMS) include: voltage control during charging, voltage control during discharging, charging current control, overcurrent protection, short circuit protection, overheat protection, and low temperature protection;

[0061] Voltage control during charging: The maximum safe voltage of each battery cell should be controlled at 4.2V. The BMS should automatically reduce the charging current when the battery cell voltage approaches 4.2V, or stop charging when it reaches 4.2V. Voltage control during discharge: The minimum safe voltage of each battery cell should be controlled at 3.0V. When the battery cell voltage drops to 3.0V, the BMS automatically stops discharging, or limits the discharge current to prevent further voltage reduction.

[0062] Charging current control: For a battery with a rated capacity of 100Ah, the maximum charging current should be set to 20A to 30A. If the charging current is greater than the set current, the overcurrent protection is triggered.

[0063] Overcurrent protection: BMS should automatically reduce or stop current output when the charging current exceeds the set maximum safe current.

[0064] Short-circuit protection: When a short-circuit condition is detected, the BMS should immediately disconnect the battery output to prevent further damage.

[0065] Overheat protection: The safe operating temperature range of the battery should be 0°C to 45°C. The BMS should automatically reduce the charging or discharging power when the battery temperature exceeds 50°C.

[0066] Low temperature protection: When the temperature is below -10℃, BMS starts battery heating to prevent battery damage.

[0067] The DC-AC inverter converts the DC power provided by the ATV battery into a standard 220V AC power. In the modular equipment access system of the ATV, the DC-AC inverter converts the DC power provided by the vehicle battery (such as 72V DC power) into 220V AC power that can be used to supply standard household appliances and other equipment.

[0068] The junction box receives 220V AC from the DC-AC inverter and manages the distribution and control of the current through internal circuits and electronic switches. The normal branching is load balancing, which can be adjusted according to specific circumstances. The junction box has multiple output ports connected to the power distribution unit smart socket module.

[0069] The DC-DC step-down converter module steps down the high voltage (such as 72V) of the battery to a low voltage (such as 12V) to supply low-voltage devices. The 12V DC is connected to the power steering and lights through cables.

[0070] In another exemplary embodiment of the present application, the external modular equipment includes but is not limited to: a snowplow, a lawn mower, a winch, a drone platform, an induction cooker, and a robotic arm. Among them, the snowplow, the lawn mower, and the winch are front-mounted equipment; the drone platform, the induction cooker, and the robotic arm are upper-mounted equipment;

[0071] In another exemplary embodiment of the present application, the internal driving equipment includes: Electric Power Steering (EPS), headlights, motor controller, instrument panel, handlebar controller, telematics BOX (T-BOX), motor and reducer;

[0072] The steering booster, lights, and motor controller are connected to the DC-DC buck module via cables;

[0074] The motor controller is connected to the handle controller via an anti-theft signal line so as to perform specific operations and safety measures when necessary;

[0075] The motor controller is connected to the telematics processor via an anti-theft power cable, allowing it to always stay connected and receive remote commands and send vehicle data;

[0076] The motor controller is connected to the motor through the Hall line.

[0077] The power steering is used to provide auxiliary force, reduce the driver's steering effort, and enhance controllability and comfort. The power steering receives 12V DC from the DC-DC step-down conversion module and assists the steering system through an appropriate control system.

[0078] The headlights are used to provide lighting functions for all-terrain vehicles. The headlights include headlights, taillights, turn signals, etc. The headlights receive 12V DC power from the DC-DC buck converter module to light up and control various headlights.

[0079] The motor controller controls the electric drive motor of the ATV, managing the motor's speed, torque and efficiency; the battery is connected to the motor controller via a 72V DC cable; the motor controller is connected to the vehicle's VCU via the CAN bus to communicate and coordinate with other systems of the vehicle.

[0080] The handlebar controller is used to provide the driver with an operating lever or button to control the start, stop, acceleration, braking and other actions of the ATV all-terrain vehicle.

[0081] Telematics processors are used to provide remote communication and connectivity features for ATVs;

[0082] The motor is used to provide power output for the ATV, driving the ATV forward or performing specific operations. The battery is connected to the motor through a 72V DC cable. The motor controller is connected to the motor through the Hall line to monitor the motor speed and position.

[0083] The reducer is used to convert the high-speed rotating power of the motor into the torque and speed required by the wheels; the motor output is connected to the reducer through a transmission system (such as gear transmission) to drive the wheels at an appropriate speed and force;

[0084] The large instrument screen is used to display and monitor the operating status and performance data of the all-terrain vehicle, and the large instrument screen can be touched and operated with single click options; the vehicle controller VCU communicates with the large instrument screen through the CAN bus, receives key parameters and information of the vehicle, and is used to issue instructions selected by the user through touch.

[0085] like Figure 2 As shown, you can enter the modular equipment management page by touching the large screen. The page will show the plan view of the ATV at a 45-degree angle. Figure 2 The five device access points (PDU locations) in the plan view will also be marked on the ATV, and the parameter status of the current device access point will be displayed at the mark. The parameter status includes: whether the switch is turned on, total current, voltage, and power. If the total current parameter of the device point is 0A, the color of the marked point will turn red, indicating that no device is connected. If the total current parameter of the device point is greater than 0A, the color of the marked point will turn green, indicating that a device has been connected. There is a "Configure" button at the mark of each device point. The configuration page can set the switch power, set the current alarm, and set the upper and lower limits of the current.

[0086] The vehicle controller VCU is used to manage and control the entire ATV system, including battery, charging, power distribution, etc.

[0087] like Figure 3As shown, the vehicle controller VCU receives the operation instructions and sends the instructions to the power distribution unit power control MCU. The power distribution unit power control MCU receives the switch power instructions from the vehicle controller VCU through the CAN bus. The power distribution unit power control MCU then sends control instructions to the power distribution unit smart socket module through the 485 line, thereby realizing remote control of the power on and off of each device on the all-terrain vehicle. Users can manage and distribute the power supply of multiple devices at the same time to ensure the stable operation of each device.
