Embodiment Construction
[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0050] In this specification, when an element is referred to as being "connected or coupled to" another element or "disposed in another element", it may be "directly" connected or coupled to the other element or " directly" is set in another element. or connected to or coupled to or disposed in another element with other elements interposed therebetween, unless it is volumetrically "coupled or connected to" another element or "directly disposed" in another element in a component. In addition, it will be understood that when an element is referred to as being "on," "above," "beneath" or "beneath" another element, it can be the same as that of another element. An element "directly" contacts or is in contact with another element with other elements interposed therebetween unle...

The invention belongs to the technical field of electric vehicles, and particularly relates to an energy storage module, a vehicle-mounted charging system and a charging method of the vehicle-mounted charging system. The energy storage module comprises a battery pack; a BMS which is connected with the battery pack; a bidirectional DC-DC converter, wherein one end of the bidirectional DC-DC converter is connected with the battery pack, and the other end of the bidirectional DC-DC converter is connected with a power line; a controller which is connected with the BMS, the bidirectional DC-DC converter and a communication line; wherein the energy storage module is provided with a first electric connection port and a second electric connection port, and the two ends of the power line and the two ends of the communication line are connected with the first electric connection port and the second electric connection port respectively. The vehicle-mounted charging method of the energy storage module is used for charging the electric vehicle, the advantages of no waiting, no special parking space and the like are achieved, and the electric vehicle shared energy storage charging system achieved through the energy storage module has the advantages of power grid energy storage, vehicle battery changing / charging / range extending and the like.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an energy storage module, a vehicle charging system and a charging method thereof. Background technique [0002] Difficulty charging has always been the number one reason consumers refuse to buy electric vehicles. Fast charging technology and battery replacement technology are not enough to perfectly solve the problem of difficult charging of family cars. Without charging facilities, it is impossible to promote electric vehicles. However, if charging facilities are built in advance, they will encounter the problem of low utilization rate, resulting in a long way to go to recover the construction investment. It hinders the further popularization of charging infrastructure. According to the article "Development Issues and Strategy Analysis of Public Charging Pile under the Background of "New Infrastructure"", only 4% of public charging piles in my country ar...
