A method of emergency power supply for users in the case of power failure

Abstract

The invention relates to an emergency power supply method for a user under the power outage condition. The method is implemented in the mode of power supplying by an electric automobile. The method comprises the steps that household appliance identification is identified through a controller; a power supply mode is selected; the power supplying capacity of the electric automobile is determined; the period of time of a power outage is determined; finally, a power supply scheme is determined. By utilizing the discharge capacity of the electric automobile, the requirement of a user for electric energy is satisfied under the power outage condition, it is guaranteed that the user can utilize power ceaselessly when a power grid does not supply power, the reliability of power utilization is improved, and various inconveniences brought to the user by the power outage are reduced as much as possible.

Description

[0001] Technical field: [0002] The invention relates to an emergency power supply method for users in a power failure situation, and more particularly relates to an emergency power supply method for an electric vehicle to a user in a power failure situation. [0003] Background technique: [0004] The load of the power system is divided into three levels. According to the "Code for Design of Power Supply and Distribution System" (GB50052-95), the division standards of load levels are as follows: [0005] (1) The load that interrupts the power supply of the primary load will cause casualties; the load that interrupts the power supply will cause major political and economic losses; the load that interrupts the power supply will affect the normal work of power consumers with great political and economic significance. [0006] (2) Loads where the interruption of power supply will cause great political and economic losses; the interruption of power supply will affect the normal wo...

Problems solved by technology

[0005] (1) The load that interrupts the power supply of the first-level load will cause casualties; the load that interrupts the power supply will cause major political and economic losses; the load that interrupts the power supply will affect the normal work of power consumers with great political and economic significance

[0006] (2) Loads where interruption of power supply for grade loads will cause greater political and economic losses; loads where interruption of power supply will affect the normal work of important power consumers

Generally, the first and second types of users have important equipment. When planning the power supply, the emergency backup power supply in the event of a power outage should be prepared first, which will not have a major impact. For ordinary users, there is no such backup measure. Being able to wait for the grid to supply power again, although it will not have a major economic, political or personal impact, will also bring great inconvenience to users
