The invention discloses a power management method and a device for managing an external electrical device of an engine or an electric power-based mobile vehicle (such as a vehicle or a ship), thereby managing power consumption of the external electrical appliance, facilitating the user and avoiding battery power Depletion causes inconvenience and safety problems in the inability to use the mobile vehicle, further preventing premature aging of the battery due to frequent depletion. [Prior Art] Modern humans are becoming more and more dependent on mobile vehicles, ships and other mobile vehicles. With the advancement of science and technology, the volume and weight of various electrical appliances have been greatly reduced, and the power consumption has also decreased. Therefore, more and more vehicles and ships are used. Mobile computers, DVDs, LCD TVs, stereos, lights, refrigerators, camping appliances, navigators, game consoles and other external appliances are brought into vehicles and ships; more like police cars, fire engines, ambulances, and money-carrying vehicles. Special vehicles such as freight cars and buses often use digital audio, GPS, GPRS, communication equipment and many other external electrical appliances. These external electrical appliances have different power requirements (such as limiting current or different voltage range), different operating conditions, 096113038 1003097396-0 6 1363955 (if using time, length of time, personnel start, etc.), linkage agreement • (Hand- Shaking, for example, outputting a signal before cutting off the power supply, causing the external electrical device to shut down first, receiving a shutdown signal to cut off the power supply), monitoring or remote control. When the external electrical equipment is used for land reading and is used in vehicles and ships, these external electrical appliances are not managed by the control computer of the mobile vehicle. Under the limited power supply, if the external electrical appliances are not properly managed, Battery power is exhausted, resulting in safety and inconvenience of driving; moreover, due to the excessive power caused by external electrical appliances, the battery is often at a low potential or even drained. The battery life is shortened, affecting normal use, especially in electric vehicles. Obvious. Therefore, the development of convenient and effective power management not only improves the convenience of users, but also improves the safety of driving. Although some vehicles or ships have generators (or external power sources, solar power), when the power consumption of vehicle electrical appliances and external electrical appliances is greater than the power generated by the power source to the c-source generators, or the vehicle's flameout generators are no longer When generating electrical energy, the external electrical appliance can only be powered by the battery pack, so managing the use of electricity is a priority. This situation also occurs in some vehicles and ships that have solar power as a source of electricity, but when these external sources of electricity * supply is interrupted or insufficient, it is also necessary to manage the use of electrical power. The prior art is to manage the in-vehicle power of U.S. Patent No. 6,111,731 and U.S. Patent No. 5,327,068, and to provide an example to immediately remove the battery when the engine is stopped, or immediately after a period of 7 096,113,038, 100,0,037,396,0,1,363,955. Examples of power supply ^ These technologies can meet the need for mobile vehicles to no longer need power after stopping the engine, but for continued use of electrical appliances, battery power management devices are still needed for power management to ensure that the battery has enough It is quite necessary that the power can be used to restart the vehicle or travel to the next power supply station. For example, U.S. Patent No. 5,945,808 proposes charging management for a battery pack supplemented by a steam-electric hybrid vehicle, but does not propose a power management method or device for an electrical appliance connected to the battery pack; and, for example, the Republic of China Patent Publication No. 200619919 The power management method and device proposed in the electric appliance, such as the vehicle computer system, try to reduce the power consumption when parking, and lack the power management of the external electrical appliance and the charging and the required discharge management of the battery pack; M288997, which proposes the power management method and device for external electrical appliances, but for the lack of prioritized power management for each external electrical device, the user cannot use the external electrical appliance power supply according to the priority of the external electrical appliance, and still has the function. insufficient. Therefore, it would be highly desirable for users to develop a method and apparatus that integrates all external electrical appliances to limit current, switching voltage, linkable protocols, can be manually switched, and has power usage priorities for power management.

Satellite TV and rear seat entertainment system are the second priority power, which is closed for the second stage; digital video The equipment and mobile computer equipment are set as the highest priority power supply equipment by the mobile vehicle user. When the vehicle battery 1 is exhausted, the supply is stopped. Since the mobile vehicle user has a delay time for the digital video equipment and the mobile computer equipment, That is, when the time arrives or the voltage drops to the set value, the switch 4 is delayed by 3 minutes or 5 minutes. 10M or switch 41 ON turns off the power supply; for the navigator and mobile computer equipment, there is another linkage agreement. When the navigator is turned on or off, the main controller 405 sends a power on or off signal to the display 408 and the buzzer 407. Further, it can be sent to the communication machine 3Z for external notification; the mobile computer equipment must send the agreement signal before the power is turned off, so that the mobile computer can close the software and hardware system; and before the power is turned on, the agreement signal must be sent to make the action The computer first turns on the hard system C system and the software system.
