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.
