Problems solved by technology
[0002] The layout of the existing electric vehicle battery cells is unreasonable and the integration level is low, which leads to complicated production and installation. It takes a lot of time to connect the lines and the production cost is high. It is heavy, not suitable for the lightweight requirements of bicycles, and has great assembly restrictions
Chinese patent announcement document CN205028952U discloses a down-tube lithium battery box for electric bicycles. Its structure includes a front cover, a rear cover, a control box, and guide rails. The overall structure is more suitable for the installation requirements of electric bicycles, but no key components are provided. (such as battery protection board) installation position, component installation is random, which affects battery assembly, and does not improve the overall integration (such as controller integration)
In addition, the existing electric vehicle battery structure does not have an anti-sparking design. When the battery is connected to the controller, because the controller is a capacitive load, there is a strong hidden danger of sparks, which may damage key components such as connectors and switches, and may even cause a fire; in the field of electric vehicles, the above problems can be realized through circuit control, as the Chinese patent publication CN102460820A discloses a system and method for the output contactor of the battery pack, adding a pre-charging circuit in the battery pack to limit the Starting current and pre-charging circuit control are mostly realized through the cooperation of relays, sensors and other equipment, which increases the complexity and cost of the circuit board. In addition, it is difficult to refit on the basis of existing electric vehicle batteries, so it is not used in the electric vehicle battery market. Products with pre-charge function appear

Embodiment 1
[0038] This embodiment is used for power supply and control of electric bicycles / mountain bikes, because this embodiment has smaller volume and lighter weight, so it is suitable for installation and application of electric bicycles / mountain bikes, except for electric bikes / mountain bikes In addition, it can also be installed and used on ordinary electric vehicles. Such as figure 1 and 2 As shown, the housing of this embodiment is divided into two parts, the power supply housing 1 and the control housing 2. The bottom of the control housing 2 is fixedly connected with the guide plate 3, and the power supply housing 1 is translated and guided in the horizontal direction through the guide plate 3, and realizes Limiting after docking with the control shell 2; in other embodiments, the power supply shell 1 and the control shell 2 can be docked obliquely or vertically, and the orientation of the guide plate 3 can be adjusted according to the actual docking direction; in other imple...

The invention relates to an electric vehicle battery with a pre-charging function. The structure of the electric vehicle battery comprises a power source shell, a control shell, a power source assembly and a control assembly, the power source shell and the control shell are arranged in a separable mode, the power source assembly is arranged on the power source shell, the control assembly is arranged on the control shell, at least one of a first pre-charging connecting piece and a second pre-charging connecting piece is provided with a pre-charging extension part extending out of the power source shell or the control shell, the extension direction of a power supply extension part is consistent with that of the pre-charging extension part, and the length / or the sum of the length of the pre-charging extension part is greater than the length / the sum of the length of the power supply extension part. According to the technical scheme, the electric vehicle battery is reasonable in structural design, small in size and light in weight, achieves the pre-charging function through a physical structure and is particularly suitable for bicycle installation.
Description
technical field [0001] The invention relates to a battery structure, in particular to an electric vehicle battery with a pre-charging function. Background technique [0002] The layout of the existing electric vehicle battery cells is unreasonable and the integration level is low, which leads to complicated production and installation. It takes a lot of time to connect the lines and the production cost is high. The weight is relatively heavy, which is not suitable for the lightweight requirements of bicycles, and has great assembly restrictions. Chinese patent announcement document CN205028952U discloses a down-tube lithium battery box for electric bicycles. Its structure includes a front cover, a rear cover, a control box, and guide rails. The overall structure is more suitable for the installation requirements of electric bicycles, but no key components are provided. (such as battery protection board) installation position, component installation is arbitrary, which affec...
