Embodiment 1

[0041] such as 1~ Figure 4 As shown, a multi-functional battery cover 100 for realizing the integrated connection between the power battery pack and the battery management system mainly includes: a cover body 1, several lead-out terminals 3 provided on the cover body 1, and at least An electrical signal acquisition unit, each input end of the electrical signal acquisition unit is connected to a power battery pack 17 ( Figure 4 As shown), the single single battery 11 is connected to each other, and the output end of each electrical signal acquisition unit is connected to a lead-out terminal 3, and several lead-out terminals 3 are connected to a battery management system, which is used to collect the power battery Pack of 17 ( Figure 4 Shown) the voltage information is sent to the battery management system.

[0042] The electrical signal acquisition unit includes: a wire 2 and a conductive elastic connector, wherein one end of the conductive elastic connector is electricall...

Embodiment 2

[0057] Such as figure 1 As shown, the difference between this embodiment and Embodiment 1 is that the conductive elastic connector in this embodiment also includes: a connecting spring 7 (such as image 3 , Figure 6a , Figure 7b shown), the connection spring 7 is connected in parallel with the connection shrapnel 6. Specifically, the connecting spring can be sleeved on the fixing column drawn from the single battery, so that the electrical flexible connection between the connecting shrapnel and the battery can be further strengthened, and at the same time, it can also play the role of assisting positioning and further strengthening the electrical connection of the signal line. reliability of the electrical connection. For example, the connection spring can be tin-soldered on the lead-out point of the wire, so that the connection shrapnel 6 (or connection spring) and the fixing post 12 of the single battery 11 (such as image 3 shown) can be connected flexibly, so that th...

Embodiment 3

[0067] The difference between this embodiment and Embodiment 2 is that each electrical signal acquisition unit in this embodiment is also connected to a fuse. Signal collection port, the two ends of each branch fuse 5 are respectively connected in parallel to an electrical signal collection port 22 and a current equalization signal collection port 21, so that the lead-out terminal of the multifunctional battery cover will collect each The electrical signal of the single battery is sent to the corresponding port of the external battery management system, which can play the dual role of voltage detection and current balance during charging, so as to effectively control and detect the performance of the single battery and improve the service life of the battery.

[0068] image 3 The multifunctional battery cover of this embodiment is included. Such as image 3 and Figure 4 As shown, the wire 2 , the connecting shrapnel 6 , the connecting spring 7 , and the lead-out terminals...

Abstract

A multifunctional battery cover (100) and a power battery pack (17) thereof. The multifunctional battery cover (100) comprises a cover body (1), a plurality of leading-out terminals (3) disposed on the cover body (1), and at least one electric signal collecting unit. An input end of each electric signal collecting unit is connected with a single battery cell (11) in the battery pack. An output end of each electric signal collecting unit is connected with one of the leading-out terminals (3). The leading-out terminals (3) are all connected with a battery management system, and are used for transmitting collected voltage information of the battery pack (17) to the battery management system. The multifunctional battery cover (100) has advantages of simple and reliable assembly and strong anti-interference capability. In addition, the leading-out terminals (3) of the multifunctional battery cover (100) send the collected electric signals of each battery cell (11) in the battery pack (17) to the external battery management system, thus achieving dual effects of voltage detection and current equalization during charging; therefore, the performance of the battery cell can be effectively controlled and detected, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the fields of electric vehicles and energy storage, in particular to a multifunctional battery cover and a power battery pack thereof. Background technique [0002] As the main energy storage body of electric energy, traction battery is developing rapidly. It can be said that solving the problem of battery energy storage provides the basis for the rapid promotion of new energy generation technologies such as solar energy and wind energy, distributed power supplies, and electric vehicles.
