Technical field
The utility model is related to a kind of voltage, temperature acquisition components, and in particular to a kind of battery modules voltage, temperature acquisition
Component belongs to New-energy electric vehicle accessory technical field.
Background technology
With the development of social science and technology, electric vehicle is with its high-environmental is energy saving, light and handy convenience and cheap advantage are got over
It more gets the favour of people, application is also more and more common.
Wherein, the power source of electric vehicle is electric energy, therefore, usually selects the battery pack that lithium battery is formed as electronic vapour
The energy-storage units of vehicle.Wherein, lithium battery has the characteristics that energy density is high, small, power density is high, using lithium battery conduct
Energy-storage units have become current electric vehicle mainstream developing direction.In practical application, since lithium battery is for voltage and temperature
Degree is more sensitive, i.e., the minor change of voltage and temperature can all play battery performance and produce serious influence.
And the voltage temperature as one of battery management system core technology acquires, it is substantially uniform in its acquisition chip at present
In the case of change, technology and mode that chip exterior is connect with battery core body, for the acquisition of battery management system voltage temperature
Accuracy just seems critically important.
At present, the acquisition of existing temperature voltage is locked to harness joint terminal based on the acquisition mode on battery core surface, peace
Full property and reliability are not guaranteed, and the cleaning difficulty of harness is larger.
Therefore, how battery core voltage, temperature are more preferably more accurately acquired, becomes weigh battery management system performance one
Important indicator.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, provide a kind of battery modules voltage, temperature
Acquisition component solves and acquires cell voltage, difficult wiring caused by temperature, of high cost in the prior art, and temperature acquisition is accurate
The problem of really property is poor.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of battery modules voltage, temperature acquisition group
Part, including collection plate, the collection plate is made of flexible PCB；The flexible PCB includes voltage, temperature acquisition member
The matrix of part；The voltage, temperature acquisition element have it is multigroup, be sequentially arranged and be fixed to N rows and M row.
Further improved as the utility model, voltage, temperature acquisition element include thermistor and three described in every group
Pole pipe.
Further improved as the utility model, the flexible PCB includes base portion and connection is adopted on the base portion
Collect item；The pick-up slip is arranged with M；There is voltage, temperature acquisition element described in N rows described in each column on pick-up slip.
It is further improved as the utility model, further include main control chip and connector；The voltage, temperature acquisition member
Number of packages passes data to the main control chip according to after acquisition by flexible PCB, and the main control chip analyzes data, then leads to
It crosses connector and is transmitted to external display.
It is further improved as the utility model, the voltage, the distribution of temperature acquisition element matrix, at least with 8 rows,
8 row.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
The battery modules voltage, temperature acquisition component of the utility model play each voltage of connection, temperature using flexible PCB
The conducting wire effect of acquisition elements is spent, wherein voltage, temperature acquisition element matrix are distributed in flexible PCB, can be to battery pack pair
Point bit test；Using flexible PCB plate good toughness, it can be assembled according to battery pack and any angle is required to bend, it is easy for installation；Gram
Taken it is traditional acquisition harness length it is irregular, the shortcomings that harness standard can not be unified, can succinct harness, optimize battery system
Layout.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is the battery modules voltage of the utility model, the structure diagram of temperature acquisition component.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of battery modules voltage described in the utility model, temperature acquisition component, including collection plate,
The collection plate is made of flexible PCB；The flexible PCB includes the matrix of voltage, temperature acquisition element 1；It is described
Voltage, temperature acquisition element 1 have it is multigroup, be sequentially arranged and be fixed to N rows and M row, wherein, N >=8, M >=8.
Flexible PCB includes base portion 11 and connection pick-up slip 12 on the base portion；Pick-up slip 12 has 8 row；Each column institute
Stating has 8 row voltages, temperature acquisition element on pick-up slip, so as to constitute 64 temperature detecting points, can acquire battery respectively
The temperature of group different location.
The voltage of each test point, there are one thermistor and a triodes for temperature acquisition element tool.Wherein, temperature-sensitive electricity
Temperature acquisition is played the role of in resistance, and triode is mainly voltage stabilizing, and overload protection prevents the excessive resistance to sparking of voltage instantaneous.Each
BMS (Battary management systen) system can be according to battery pack size, temperature acquisition density requirement, selection
The quantity of acquisition component.
Main control chip 13, main control chip are passed data to by FPC (flexible PCB) after thermistor temp acquisition
13 analysis data, then external display is transmitted to by connector 14, to check.
The battery modules voltage, temperature acquisition component of the utility model, can be arbitrary according to battery pack assembling requirement
Angle bend, test point matrix distribution, can to battery group to point bit test, can be needed according to battery pack increase amount detection come
Increase test point；It is light-weight, small, thickness is thin, low manufacture cost.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
