Description
Technical field
This utility model relates to power battery technology field, is specifically related to a kind of electrokinetic cell module system.
Background technology
At present, electrokinetic cell module system is mainly made up of multiple cells, structural member and copper bar, and structure is relatively easy and is easily achieved, but there is following defect:
When multiple electrokinetic cell modules are assembled into whole electrokinetic cell system, often string battery is required for connecting voltage acquisition line for detecting cell voltage, arrange in module that temperature acquisition line is used for detecting battery temperature, thus electrokinetic cell system collection wire harness is various, influential system aesthetic property, and assembly technology is complicated, it is not easy to safeguard. Additionally, due to gathering line node is more, causing trouble point increases, and electrokinetic cell system reliability reduces. Voltage acquisition line is high-voltage line, and temperature acquisition line is low-voltage line, when doing battery system voltage-withstand test or Insulation test, easily causes interference between high-voltage line and low-voltage line, and the gathering line that partial-length is longer, then there will be certain pressure reduction problem.
Utility model content
The purpose of this utility model is to overcome shortcomings and deficiencies of the prior art, it is provided that the electrokinetic cell module system that a kind of integrated level is high, wire harness is few, reliability is high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of electrokinetic cell module system, including battery unit and from control unit, described battery unit is made up of multiple cells; Described from control unit include information acquisition module and communication module; Described information acquisition module is connected with battery unit, communication module signal respectively, described communication module is also connected with battery management system signal, described information acquisition module gathers the information of voltage of battery unit, temperature information, and the information of voltage gathered, temperature information are transmitted to communication module, information of voltage, temperature information are uploaded to battery management system, and receive the control instruction of battery management system by communication module.
It is preferred that, described communication module is connected with battery management system by CAN.
It is preferred that, described communication module is connected with external power supply also by power line, and external power supply is for powering from control unit.
It is preferred that, described communication module is connected with battery unit also by power line, by battery unit for powering from control unit.
This utility model includes advantages below and beneficial effect compared to existing technology:
(1) this utility model is integrated highly integrated to battery unit, voltage acquisition, temperature acquisition and communication, only by communication module and battery management system communication, greatly reduce battery modules system and outside rat tail, reduce battery modules system junction point, it is greatly improved the reliability of battery modules system, and saves the space that wire harness takies, simultaneously the minimizing of wire harness, it is easy to Automated assembly, and maintains easily.
(2) in battery modules, configuration information acquisition module gathers information of voltage and the temperature information of battery unit, with traditional by compared with long gathering line gathers battery cell voltage information, temperature information, gathering line is greatly shortened, it is prevented effectively from the problem that pressure reduction occurs because gathering line is long, being prevented effectively from interfering between high-voltage line and low-voltage line, battery modules system reliability is high simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment medium power battery modules system.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As it is shown in figure 1, a kind of electrokinetic cell module system, including battery unit and from controlling unit. Described battery unit is made up of multiple cells. Described from control unit include information acquisition module and communication module. Described information acquisition module is connected with battery unit, communication module signal respectively, described communication module is also connected with battery management system signal, described information acquisition module gathers the information of voltage of battery unit, temperature information, and the information of voltage gathered, temperature information are transmitted to communication module, information of voltage, temperature information are uploaded to battery management system, and receive the control instruction of battery management system by communication module.
In the present embodiment, described communication module is connected with battery management system by CAN.
It is preferred that, described communication module is connected with external power supply also by power line, and external power supply is for powering from control unit, it is also possible to be connected with battery unit by power line, by battery unit for powering from control unit.
When adopting external power supply for powering from control unit, electrokinetic cell module system and extraneous connection go out routine total just, outside total negative interface, the only CAN interface of communication module and electric source line interface; When adopting battery unit for powering from control unit, electrokinetic cell module system and extraneous connection go out the total of routine and just, always bear outside interface, the only CAN interface of communication module, wire harness is simple, battery modules system junction point is few, it is greatly improved the reliability of battery modules system, and saves the space that wire harness takies, simultaneously the minimizing of wire harness, it is easy to Automated assembly, and maintains easily. Additionally, gathering line is greatly shortened, being prevented effectively from the problem occurring pressure reduction because gathering line is long, be prevented effectively from interfering between high-voltage line and low-voltage line simultaneously, battery modules system reliability is high.
Embodiment described above only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims. It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model. Therefore, the protection domain of this utility model patent should be as the criterion with claims.
