Description
Technical field
This utility model relates to electric vehicle engineering field, is specifically related to a kind of novel battery management system.
Background technology
Current BMS system includes a main frame and several are from machine, and each connects set of cells respectively from machine, battery total
Pressure detection is realized by main frame, owing to from the limited amount of machine, the set of cells string number of its correspondence is universal the biggest, single from
The battery voltage error that machine examination measures is relatively big, causes the precision of Host Detection voltage to reduce.Meanwhile, because each producer is to electricity
The different requirements of tankage, cause the signal wire harness kind in battery management system more, it is impossible to be standardized design, cause
Production cost rises, and configuration process is relatively complicated.
It addition, traditional B MS system only has battery and the Insulation monitoring of car shell, one is used to control a battery case from machine
Mode to realize the Insulation monitoring to each battery case shell the most unrealistic, traditional framework exists battery leakage fault cannot
The hidden danger of monitoring, cannot quickly position after battery leakage fault.
Utility model content
This utility model provides a kind of novel battery pipe that can quickly realize the detection of battery stagnation pressure and battery leakage monitoring
Reason system, can detect that insulation resistance change when battery leakage, thus realize the mesh of monitoring battery leakage fault the very first time
's.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of novel battery management system, including a CCU main frame, BMU from machine, several CU control modules and
The set of cells of connection corresponding with this CU control module, described CCU main frame is connected from machine with BMU, and described BMU controls mould from machine with CU
Block connects, and uses daisy chaining to connect between described CU control module, and described CCU main frame is for collection vehicle information and controls
BMU is used for detecting the stagnation pressure of battery and for detecting battery and battery from machine from the duty of machine management battery, described BMU
The insulation resistance of case shell, described CU control module possesses monomer voltage acquisition function.
Preferably, described CCU main frame is connected by CAN communication from machine with BMU.
Preferably, described BMU is connected by High Speed Serial communication between machine with CU control module.
Preferably, described set of cells uses one of them or several combination of 2 strings, 4 strings and 8 string type.
From above technical scheme, this utility model detects the exhausted of battery and battery case shell by BMU from function
Edge resistance, thus monitor the faults such as battery leakage, can faster position fail battery case, it is achieved quick-replaceable；Each CU controls mould
Block possesses monomer voltage acquisition function, and the battery that single CU control module controls can more precisely detect less because of quantity, BMU
Can quickly realize the detection of battery stagnation pressure, more preferably ensure safety；This utility model has only to design 3 kinds of signal wire harness, and will not
Because each producer difference requires to produce change, after so wire harness is standardized design, not only reduce cost, Er Qiemo
The redesign process of the BMS of massing design also can become simple to operation, does not interferes with the function of other parts.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
In figure: 1, CCU main frame, 2, BMU from machine, 3, CU control module, 4, set of cells.
Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present utility model is described in detail.
As it is shown in figure 1, described battery management system includes that 1, BMU of a CCU main frame controls from machine 2, several CU
Module 3 and the set of cells 4 of connection corresponding with this CU control module.
Described CCU main frame 1 is connected by CAN communication from machine 2 with BMU, and described BMU is logical between machine 2 and CU control module 3
Crossing SPI or other High Speed Serial communications connect, described set of cells 4 uses one of them of 2 strings, 4 strings and 8 string type or several
Combination, so design can meet the different requirements of each producer.
Described CCU main frame 1 is for collection vehicle information and controls BMU and manages the duty of battery, CCU main frame from machine 2
Function be to measure assembled battery total voltage, collect BMU and the data of high pressure strong power part, carry out battery data concentrating analyze and
Process, it is judged that the fault of present battery, carry out early warning and the warning of battery system, and the data comprehensively utilizing battery carry out battery
SOC estimate, it was predicted that the residue course continuation mileage of electric automobile.
Using daisy chaining to connect between described CU control module 3, each CU control module possesses monomer voltage collection
Function, and it is aggregated into BMU from machine 2, for detecting the stagnation pressure of battery, the number of batteries controlled due to single CU control module is few
Voltage can more precisely be detected, BMU can quickly realize the detection of battery stagnation pressure.CU control module 3 is controlled the size less respectively
Set of cells so that the versatility of whole system is stronger, can be realized the battery of customization by the independent assortment of each set of cells
Capacity, required signal wire harness kind fixes, and cost is relatively low.
This utility model designs insulation monitoring module and the relay for circuit protection at BMU from machine 2, thus
Battery and the insulation resistance of battery case shell can be detected, thus monitor the faults such as battery leakage, and fault message is passed to
BMU, can faster position fail battery case, it is achieved quick change.During battery leakage, electrolyte contacts conducting with battery case shell, reduces
The insulation resistance value of car load, BMU can receive rapidly this value, processes leakage situation in time.
The above embodiment is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the guarantor that claims of the present utility model determine
In the range of protecting.
