Problems solved by technology

[0003] (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
[0004] (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

Embodiment 1

[0032] Such as figure 1 As shown, the invention of this example is an emergency power supply method for users in a power failure situation, and the method is realized by means of electric vehicle power supply; the method includes the following steps:

[0033] (1) Identification of household appliances

[0034] The power supply scheme of the present invention is formulated according to the types of household appliances, so the first step in the realization of the present invention is to collect all household electrical equipment and attach an Internet of Things label to each equipment, so that the controller can identify the ones that require power supply Which device, decides whether to grant the request.

[0035] (2) Set multiple power supply modes

[0036] The electric vehicle participation power supply mode can be set to two modes: automatic or user-defined. In the automatic mode, according to the battery SOC information of the electric vehicle, it automatically controls...

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

Technical field: [0001] 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. Background technique: [0002] 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: [0003] (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. [0004] (2) Loads where the interruption of power supply will cause great political and economic losses; the interruption of power supply will affect the normal work of important...
