Description

A kind of enhanced battery management system
Technical field
The present invention relates to the field of battery management of electric car, and in particular to a kind of enhanced battery management system.
Background technique
Battery management system (Battery Management System, BMS) is the important component part of electric car. There are two types of the BMS routinely used currently on the market, low in cost one is centralized BMS, and control is simple;But it exists can The features such as scalability is poor, and maintainability is poor, and maintenance cost is high causes the limitation of its own;Another kind is distributed BMS, it Though solve the confinement problems of centralized BMS, there is also with high costs, the problems such as controlling complex management, to management and dimension Shield brings difficulty.In BMS, it is mainly the important information acquired in real time, in processing storage battery group operational process, simultaneously Key issues of exchanging information with external equipment such as entire car controller, solving safety, service life in battery system.
Meanwhile with the development of electric vehicle engineering, the market scale of electric car is increasing, must pursue higher property The electric car of energy.Core system of the BMS as the battery management of electric car, BMS functional diversities and BMS function are extending Property to promote battery management system development, and then push Development of Electric Vehicles play a significant role.
Summary of the invention
The present invention provides a kind of enhanced battery management systems, detail as per Fig. 1.By providing alternative inside Communication mode and battery balanced mode intend to solve high cost present in different BMS frameworks, the difficult points such as scalability difference, it is intended to increase The diversification of strong battery management system function, improves its using flexible.
In order to achieve the above object, the technical solution adopted by the present invention is that:
The present invention provides a kind of enhanced battery management system, including host computer interface, active equalization module, passive equilibrium Circuit, master control M-BMS and S-BMS, internal communication mode select switch (or component of other similar function) and master passive equal It weighs mode selection switch (or component of other similar function).S-BMS is developed based on BQ76PL455A-Q1, for pair Every battery parameter is managed monitoring.M-BMS is mainly used for the selection of various line traffics.The internal communication mode selects Main operation modes of the switch for the enhanced battery management system select.The passive balanced mode selection switch of master is used for The selection of battery balanced mode in the enhanced battery management system.
Select switch (or component of other similar function) come increasing described in dynamic select by the internal communication mode The main operation modes of strong type battery management system.The enhanced battery management system: 1) with the battery of master-slave architecture Management system function.It can be managed monitoring to battery parameters, while also have the function of the various line traffics of selection, Detail as per Fig. 2;2) have the function of M-BMS in the battery management system of master-slave architecture, various line traffics can be carried out Selection, detail as per Fig. 3;3) have the function of B-MBS in the battery management system of master-slave architecture, it can be to battery parameters It is managed and monitors, detail as per Fig. 4.
Reinforced electric may be selected by the passive balanced mode selection switch (or component of other similar function) of the master The battery balanced mode of pond management system.The enhanced battery management system: 1) battery actively carries out balanced, detail as per figure 5;2) battery carries out passive balanced, detail as per Fig. 6.

Specific embodiment
In order to which the purpose of the present invention, design scheme and advantage is more clearly understood, the present invention is made with reference to the accompanying drawing It further describes.
As shown in Figure 1, the enhanced battery management system includes host computer interface, active equalization module, passive equilibrium Circuit, master control M-BMS and S-BMS, internal communication mode select switch (or component of other similar function) and master passive equal It weighs mode selection switch (or component of other similar function).Internal communication mode and battery balanced mode can be independently selected, The different demands that can satisfy different clients are designed in this way.
Further, as shown in Fig. 2, by selecting internal communication mode, the enhanced battery management system be can be used as One independent master-slave architecture battery management system to use function possessed by realization master-slave architecture battery management system Energy.
Further, as shown in figure 3, by selecting internal communication mode, the enhanced battery management system can be realized The function of M-BMS in client/server formula battery management system is realized in battery management system to each line traffic.
Further, as described in Figure 4, by selecting internal communication mode, the enhanced battery management system can be realized The function of S-BMS in client/server formula battery management system, realization select the management of battery parameter and monitoring function.
Further, as described in Figure 5, the enhanced battery management system can realize active equalization of battery function.
Further, as described in Figure 6, the enhanced battery management system can provide the passive balanced function of battery.
Embodiment described above is only that preferred embodiments of the present invention will be described, not to model of the invention It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention The various changes and improvements that case is made, should fall within the scope of protection determined by the claims of the present invention.
