Embodiment 1

[0046] Such as figure 1 As shown, this embodiment provides a portable energy storage system for emergency use of electric vehicles. The portable energy storage system includes: an emergency system charging module 101, an energy storage module 102, an energy storage management module 103, an emergency system discharging module 104, A monitoring module 105 and a communication module 106 .

[0047] The emergency system charging module 101 is used to transfer external electric energy to the energy storage module 102 in the emergency system, and the external energy source includes one or both of electric energy in the grid, solar energy, wind energy, and electric energy generated by a generator. combination of the above. The emergency system charging module 101 includes one of a DC-to-DC module and an AC-to-DC module.

[0048] The energy storage module 102 is used to store electrical energy; the energy storage module 102 includes a module composed of a secondary battery or a superc...

Embodiment 2

[0061] Such as figure 2 As mentioned above, this embodiment provides a portable energy storage system for emergency use of electric vehicles. Its basic structure is as in Embodiment 1. The difference from Embodiment 1 is that the input power used in this embodiment is a case of 380V AC grid . Since the power grid provides AC power, but the energy storage module 102 needs DC power, therefore, in this embodiment, the emergency system charging module 101 is selected as the AC to DC module 201 (AC / DC).

Embodiment 3

[0063] Such as image 3 As shown, this embodiment provides a portable energy storage system for emergency use of electric vehicles. Its basic structure is as in Embodiment 1. The difference from Embodiment 1 is that the input power used in this embodiment is a 380V AC grid. The emergency charging module is selected as an AC-to-DC module 201 (AC / DC), and the emergency system discharge module 104 is selected as a DC-to-DC module 304 (DC / DC). This mode is used in the fast charging mode of the electric vehicle, that is, the energy storage module 102 directly charges the battery pack in the electric vehicle through the DC / DC module.

Abstract

The invention provides a portable energy storage system for electric vehicle emergencies and a working method of the portable energy storage system. The portable energy storage system includes an emergency system charging module, an energy storage module, an energy storage management module, an emergency system discharging module, a monitoring module and a communication module. According to the portable energy storage system of the invention, a solution is provided for electric vehicle fast rescue; emergency system charging equipment, emergency system discharging equipment and emergency system energy storage equipment are arranged independently; in electric vehicle rescue, it only needs to carry the emergency system energy storage equipment and the emergency system discharging equipment, and the emergency system charging equipment is not required, and therefore, the portable energy storage system is convenient and fast, and a user only needs to pay a small fee. The weight and size of the emergency energy storage system can be effectively decreased, the portability of the system is improved, and rescue cost can be reduced. The portable energy storage system has a wide application prospect in the electric vehicle emergency rescue field.

Description

technical field [0001] The invention relates to the field of emergency rescue of electric vehicles, in particular to a portable energy storage system for emergency use of electric vehicles and a working method thereof. Background technique [0002] As an environmentally friendly means of transportation, electric vehicles have received more and more attention from the government, and have gradually become a way for people to travel green. At this stage, the electric vehicle industry is still in the initial stage of development, and electric vehicle charging piles are mainly distributed in residential quarters and public places. Therefore, during the driving of electric vehicles, there will be a shortage of electricity, but it is difficult to replenish it immediately, which not only brings inconvenience to people's travel, but also increases the mileage anxiety of electric vehicle users. [0003] So far, various methods for electric vehicle rescue have been proposed. For exa...
