Embodiment 1

[0030] Such as figure 1 As shown, the super-high-power electric vehicle fast charging equipment includes a power supply device 1 , a charging device 2 and a control device 3 .

[0031] The power supply unit 1 is used to step down the high voltage input from the power grid and then output multi-channel AC power. The power supply unit 1 has a built-in 1000KVA transformer, and the output low voltage supplies power to the AC / DC module 21 and the terminal through the AC bus 26 . The power input chooses a high-voltage transmission network with a larger capacity, which solves the problem of power capacity, and stores energy in advance when the power consumption is low, reducing the impact on the power grid.

[0032] Such as image 3 As shown, the charging device 2 includes a plurality of AC / DC modules 21, a logic matrix switch 22, a plurality of DC charging guns 23, a plurality of DC / DC modules 24 and an energy storage module 25, and the logic matrix switch 22 passes each AC / DC The...

Embodiment 2

[0037] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that in this embodiment, a plurality of AC charging guns 28 are added to the super-high-power electric vehicle fast charging device in Embodiment 1, and the AC busbar 26 is connected 28 with a plurality of AC charging guns. Compared with Embodiment 1, the ultra-high-power electric vehicle fast charging device in this embodiment can not only perform DC charging through the DC charging gun 23, but also perform AC charging through the AC charging gun 28, which can meet the charging needs of different models.

Abstract

The invention relates to fast charging equipment for a super-power electric car. The fast charging equipment for the super-power electric car includes a power source device, a charging device and a control device connected with the charging device; the power source device is connected with a power grid and used for reducing high voltage input by the power grid and then outputting multiple-channelalternating current; the charging device is connected with the power source device and used for charging a battery of the electric car; the control device is used for accessing an electric car batterymanagement system, collecting battery information, automatically configuring charging parameters according to demands of the electric car battery management system, and receiving instructions for adjusting the charging parameters from the electric car battery management system in real time. The fast charging equipment for the super-power electric car has the advantages that the output power is high, the investment cost and operating expense are low, the output power is continuous and adjustable, and impact on the power grid is small.

Description

technical field [0001] The invention relates to the technical field of power electronics and control, in particular to a fast charging device for an ultra-high-power electric vehicle. Background technique [0002] Compared with traditional cars, the main disadvantage of electric vehicles is the charging process. How to achieve the same energy storage process experience as traditional cars is the key to the development of electric vehicles. Charging technology mainly depends on the performance of battery materials and types, and the development of fast-charging batteries is an inevitable trend. Due to the large storage capacity of the power battery of electric vehicles, in order to achieve the same convenient energy storage process as gasoline vehicles, it is necessary to complete the 100kw / h power output within 10-20 minutes. The two vehicles are charged at the same time, and the output power of the charging equipment will reach 750KW. . Such a large power will be unbearab...
