The control system may be implemented using two schemes:

The scheme one is as shown in fig. 10, wherein the PV module (photovoltaic panel) is connected with the EV charging communication and control module through the cooperation of the MPPT controller and the micro-inverter, and the EV charging communication and control module (optionally the intelligent module SIM8500 or the remote EC200S module is selected according to actual needs) is used for monitoring the whole process of identifying, communicating and charging the new energy electric automobile 80. The PV module (photovoltaic panel) is connected to the roof battery 70 through another MPPT controller, and the DC/DC module is responsible for converting the DC power of the roof battery 70 into different voltages required by the vehicle electronics.

Meanwhile, the USB/Type-C/12V charging management module provides a standard power supply for the electronic equipment. The starting control module of the vehicle-mounted electronic device is mainly responsible for managing and coordinating the electronic system in the vehicle when the vehicle is stopped, so as to ensure the safety, comfort and performance of the vehicle, such as illumination, windows, door locks, seat control and the like. The launch control module manages these functions by receiving sensor data and executing control instructions while the vehicle is stopped. For example, when the vehicle is stopped, unnecessary electronic devices may be turned off to save energy and ensure that they can be quickly activated when needed to resume normal operation of the vehicle. The starting control module of the vehicle-mounted electronic equipment ensures that the vehicle keeps safe and efficient in a stopped state by processing and coordinating different subsystems in real time when the vehicle stops, and responds to start related functions quickly when needed.

The sentry module monitors the vehicle state when the vehicle is parked, ensures the vehicle safety, prevents illegal invasion or abnormal conditions, forms a closed-loop energy management system, aims to improve the energy efficiency of the electric vehicle 80, and provides safe and reliable power supply.

The second scheme is shown in fig. 11, wherein an MCU (micro control unit) is responsible for monitoring and controlling the charging process of the vehicle, the power distribution of the vehicle-mounted electronic equipment and the operation of the sentinel module. When the charging gun is plugged into the vehicle charging socket, the MCU immediately activates the DC/DC module (OUT DC: 800V), converts the external power supply to a voltage suitable for the vehicle battery, and starts charging. After the charging is finished or when the charging gun is pulled out, the MCU can automatically close the DC/DC module so as to save energy. In addition, the MCU also monitors the state of charge of the vehicle by detecting the voltage on S+/S-.

When the vehicle is in flameout, the MCU optimizes solar energy collected from the PV module through the MPPT+microcontroller unit, and converts electric energy into voltage suitable for vehicle-mounted electronic equipment through the DC/DC module (OUT DC: 12V/5V), so as to supply power for vehicle-mounted systems such as a central control screen, a seat, glass lifting and the like. Meanwhile, the MCU also controls the power supply of the vehicle air conditioning system, so that a comfortable environment can be provided for passengers when the vehicle is parked.

The sentry module is automatically switched to the roof photovoltaic power generation power supply for power supply after the vehicle is flameout, and is switched back to the auxiliary battery for power supply of the vehicle when the vehicle is started, so that energy can be saved, and the service life of the auxiliary battery can be prolonged. The sentry module will enter a low power video mode when the vehicle is not vibrating and there are no moving objects around, and will start immediately to provide monitoring once a vibration or moving object is detected. This function is achieved by a shock sensor and a motion sensor. When the vehicle is stopped for more than a set time (such as 5 minutes), the MCU starts a DC/DC module (OUTDC:12V) to provide power for the vehicle-mounted electronic equipment, and when the vehicle moves or shakes, the module is closed after 5 minutes, so that energy conservation is realized again.

The system integrally utilizes intelligent control of the MCU, ensures that the vehicle can realize low-power-consumption operation in different states through accurate power management and condition monitoring, and simultaneously ensures stable power supply and safety monitoring of vehicle electronic equipment. Such a design not only improves energy efficiency, but also enhances safety and reliability of the vehicle.

In the first and second aspects, the electrical principle of the start control module of the on-vehicle electronic device when the vehicle is stopped is as shown in fig. 12, and the ppt+roof battery pack 70 is used as the core of the energy source to supply necessary electric energy, and fine power distribution and management are performed through the soft switches 1 to 4.

The control and power supply of the vehicle air conditioning system are realized by the soft switch 1, so that a comfortable environment can be provided for passengers when the vehicle is parked. The power supply control of the vehicle central control screen is completed through the soft switch 2, so that a driver can use the central control screen to perform navigation, entertainment or other functions when the vehicle is parked. The power supply of the control system of the vehicle window and the seat is managed by the soft switch 3, so that the adjustment of the vehicle window and the seat can still be freely performed in a parking state. The automobile data recorder obtains a stable power supply through the soft switch 4, and can continuously record the surrounding environment when the automobile is parked. The whole system is intelligently controlled by an MCU (micro control unit), the MCU is responsible for coordinating the working states of all the soft switches, the power distribution is intelligently regulated according to the actual demands and external conditions of the vehicle, the energy use efficiency is optimized, and meanwhile, the stable operation of the system and the comfortable experience of passengers are ensured. Through the design, the vehicle can still keep the normal operation of the electronic equipment when parked, and meanwhile, the reasonable utilization of energy and the safety and stability of the system are ensured.

The low-power-consumption operation electric principle of the system is shown in fig. 13, and in the low-power-consumption electric principle diagram, the design goal of the system is to optimize the use of energy sources, so that the vehicle-mounted electronic equipment can operate with the lowest energy consumption when the vehicle is operated or stopped. The system realizes accurate power control of different electronic modules through the soft switch 1, the soft switch 2, the soft switch 3 and the soft switch 4. The DC/DC module (OUTDC:500V) is responsible for converting high voltage into lower voltage suitable for vehicle-mounted electronic equipment, and the EV charging communication module (which can be a sim8500 intelligent module or an MU8500CE LTE Cat 4 intelligent module, which is specifically selected according to actual needs) is responsible for communicating with external charging equipment, so that the vehicle can be charged efficiently when needed. The DC 12V outlet of the vehicle is powered by the soft switch 2 to power the conventional 12V system of the vehicle. The sentinel module receives power through the soft switch 3, this module monitors the safety of the vehicle when it is parked, while the DC/DC module (OUT DC: 12V/5V) provides power to the USB female socket, allowing the mobile device to be charged. The start control module of the on-board electronics is powered by the soft switch 4 when the vehicle is stopped, and this module is controlled by an MCU (micro control unit) in charge of managing the power supply of the electronics when the vehicle is stopped. The whole system realizes the optimal management of power distribution through the intelligent control of the MCU, ensures that the vehicle-mounted electronic equipment can obtain proper power supply under different operation modes, keeps low-energy-consumption operation, and improves the energy efficiency and the safety of the vehicle.
