Description
Technical field
The utility model relates to automobile technical field, is specifically related to a kind of automobile batteries management system.
Background technology
Along with the development of new-energy automobile industry and electric vehicle engineering, battery still becomes the key factor of restriction electric vehicle engineering development.Battery is as the core energy storage device of electric automobile; Its cost occupies the quite most of of electric automobile; And directly affect the performance of electric automobile; So concern that the battery management system in cell safety and life-span has occupied extremely important position in the research and development of electric automobile, how to prolong battery useful life, the energy efficiency and the operational reliability of raising battery, be the problem that the electric automobile energy management system must solve.
General battery management system is through gathering battery various signal parameters and basic parameter comparative analysis in use; Draw the current user mode of battery, thereby the state of control vehicle operating improves better its useful life also with the service efficiency that guarantees battery.The exploitation of novel battery has simultaneously become the emphasis of electric vehicle engineering sustainable development.At present; The battery that is applied to electric automobile also comprises Ni-MH battery, capacitor batteries and super capacitor etc. except ferric phosphate lithium cell is arranged; And the current battery management system is just to ferric phosphate lithium cell; Because every kind of battery cell voltage and characterisitic parameter all are not quite similar, the canonical parameter that battery management system presets can't compatible other batteries.If promptly use other battery, the user then need come customized corresponding management battery system according to the battery that uses, in case the replacing battery will cause management system with losing efficacy or matching degree decline.
Summary of the invention
The purpose of the utility model is the above-mentioned shortcoming that exists to prior art, and a kind of battery management system that matees the polytype battery is provided, and has greatly improved the compatibility and the flexibility of battery management system.
For realizing above-mentioned purpose, the controller lead link structure of the utility model adopts following technical scheme:
A kind of battery management system of compatible multiple battery comprises
Collecting unit is gathered the mesuring battary data message;
Processing unit is handled the battery data information that said collecting unit is gathered; And
Output control unit is characterized in that:
Also comprise an external switch that is connected with said processing unit, a plurality of dissimilar battery parameter groups that prestore in the said processing unit, said external switch may command select to use a certain type cell parameter group in the processing unit.
The parameter information of said battery parameter group comprises a certain type cell monomer voltage value, SOC value, current setting value, desired temperature.
The parameter information of said battery parameter group is a certain type cell parameter threshold, comprises monomer voltage bound threshold value, SOC bound threshold value, electric current bound threshold value, temperature bound threshold value.
The advantage of the utility model is:
The existing dissimilar battery parameter group of storage in advance in battery management system; Battery types according to reality is used selects the corresponding battery parameter group as basic parameter through external switch; Accomplish comparison process with image data; Realize the compatibility of battery management system and dissimilar batteries, improved the flexibility of system applies.
Battery types to minority is used need not to customize separately battery management system, has practiced thrift cost.
Description of drawings
Fig. 1 be the utility model can compatible multiple battery the battery management system structure chart;
Fig. 2 is the battery management system implementing procedure figure of the utility model.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing.Like Fig. 1, the 1st, battery management system, the 2nd, collecting unit, the 3rd, processing unit, the 4th, output control unit, the 5th, battery parameter group, the 6th, external switch.
The battery management system 1 of a kind of compatible multiple battery of present embodiment; Comprise the collecting unit 2 of gathering the mesuring battary data message; The battery data information processing unit 3 of gathering, processing collected unit 2, and output control unit 4 also comprise an external switch 6 that is connected with processing unit 3.Collecting unit 2 is connected with mesuring battary; Calculate comparison in output acquired signal to the processing unit 3; Outwards export control signal sending into output control unit; A plurality of dissimilar battery parameter groups 5 that prestore in the processing unit 3, external switch 6 may command select to use a certain type cell parameter group in the processing unit.
Referring to the implementing procedure figure of Fig. 2, the course of work of present embodiment is detailed below.
The three Battery pack parameters that prestored in the battery management system processing unit in the present embodiment comprise Ni-MH battery parameter, lithium manganate battery parameter and ferric phosphate lithium cell parameter, and promptly this battery management system can compatible management system as Ni-MH battery, lithium manganate battery or ferric phosphate lithium cell.Each battery parameter group all comprises the high set point of the type monomer voltage, the low set point of monomer voltage, the high set point of SOC, the low set point of SOC, current setting value, desired temperature.
If the current battery that uses is ferric phosphate lithium cell, then manually select the 3rd group of ferric phosphate lithium cell parameter with correspondence as the benchmark reduced parameter through external switch.The concrete high set point of parameter setting voltage is 3.8V, and the low set point of voltage is 2.5V, and the high set point of SOC is 90%, and SOC is low, and set point is 20%, and the excess temperature value is 60 ℃, and electric current is set at 100A according to actual loading and battery capacity size.
When system starts working; The parameters of gathering ferric phosphate lithium cell to be measured comprises monomer battery voltage, temperature, total current, total voltage; Through calculating the SOC value of battery, the parameters that collects and the SOC value and the basic parameter that calculate are compared, judge that whether battery status information reaches fault; While with information stores, is exported control signal according to battery status at last in the cycle.If be provided with and do not meet corresponding battery types, can cause the battery failures faults.
To the failure mode of battery, for preventing over-charging of battery, cell voltage is higher than the high set point of monomer voltage and just sends warning, cuts off battery charger when serious; Put for preventing that battery from crossing, cell voltage is lower than the low set point of monomer voltage just reports to the police, the low battery discharge loop that just cuts off of serious mistake; SOC represents the dump energy of whole battery group, and SOC is too high to be exactly to overcharge, and it was exactly to put that SOC crosses low; For preventing the too high heating of battery temperature, when being higher than desired temperature, battery temperature warns.
