Problems solved by technology

[0005] Due to the large number of measurement points on the battery, there will be a large number of wiring harnesses on the surface of the battery. These wiring harnesses are intricate. When assembling electric vehicles, it is easy to install the wiring harness incorrectly, which reduces the production cycle, product qualification rate and reliability. After-sales maintenance brings great trouble

Embodiment 1

[0038] An embodiment of the present invention provides a battery collection device for an electric vehicle, such as figure 1 and Figure 5 shown, which includes:

[0039] The main housing 1, the plug-in 61, the collection wire harness 31 and m wire harness terminals 41, where m is an integer greater than 1;

[0040] The main housing 1 is provided with a plug-in installation groove 6, a wire harness groove 3 and at least m first limiting grooves 4, and the wire harness groove 3 is connected to each of the plug-in installing groove 6 and at least m first limiting grooves 4 respectively. A limiting groove 4 communicates;

[0041] The m wire harness terminals 41 are respectively arranged in the m first limiting grooves 4, the plug-in 61 is arranged in the plug-in installation groove 6, and each wire harness terminal 41 in the m wire harness terminals 41 is connected to the plug-in 61 through the collection wire harness 31, and The collection wire harness 31 is arranged in the w...

Embodiment 2

[0070] An embodiment of the present invention provides a battery system for an electric vehicle, including the battery collection device and a battery pack for an electric vehicle described in Embodiment 1;

[0071] Each harness terminal 41 on the battery collection device is connected to a measurement point on the battery pack.

[0072] The battery collection device in this embodiment is completely the same as the battery collection device in Embodiment 1, so the structure of the housing will not be described in detail in this embodiment.

[0073] In this embodiment, the battery collection device can assemble the battery collection device offline by installing the collection wire harness 31, wire harness terminal 41, copper bar 51 and plug-in 61 in a main housing 1, and the completed battery collection device can be directly assembled online. The acquisition device is directly assembled around the battery pack, which achieves the purpose of modular assembly and improves the p...

Abstract

The invention discloses an electric vehicle, a battery collecting device and a battery system thereof, and belongs to the technical field of collecting devices for battery systems of electric vehicles. The battery collection device includes: a main housing, a plug-in, a collection wire harness and m wire harness terminals, where m is an integer greater than 1; the main housing is provided with a plug-in installation slot, a wire harness slot and at least m first limiting slots, The wire harness grooves communicate with the plug-in installation groove and each of the at least m first limiting grooves respectively; the m wire harness terminals are respectively arranged in the m first limiting grooves, and the plug-in is arranged in the plug-in installation groove , each of the m wire harness terminals is connected to the plug-in through a collection wire harness, and the collection wire harness is arranged in a wire harness slot. The invention clarifies the installation positions of the collection wire harness, wire harness terminals and plug-ins, makes the wiring harness of the collection wire harness clear, realizes the methodical installation of the collection wire harness around the battery pack, reduces the problem of incorrect installation of the collection wire harness position, and improves the product qualification rate .

Description

technical field [0001] The invention relates to the technical field of an electric vehicle battery system collection device, in particular to an electric vehicle and its battery collection device and battery system. Background technique [0002] The battery of an electric vehicle is a core component of the electric vehicle and the power source of the electric vehicle. Whether its operating status is normal or not is directly related to whether the electric vehicle can run normally. Therefore, the main control module of the electric vehicle needs to collect the operating parameters of the battery in real time. Determine the operating state of the battery according to the operating parameters, and take corresponding measures to deal with it when the operating state is abnormal, for example, when the operating state is that the battery is short of power, prompt the user to charge it in time. [0003] At present, the main control module can collect the operating parameters of th...
