Abstract
The utility model discloses an electric automobile is with safe type battery box, it is including BMS voltage acquisition port, BMS relay control port and group battery unit, a plurality of the group battery unit connect respectively between BMS voltage acquisition port and BMS relay control port, the group battery unit include first relay, second relay and electric core, first relay and second relay parallel connection, electric core be connected with first relay and second relay respectively. In this way, the utility model discloses in avoiding establishing ties open a way and result in the problem of the unable work of system in certain economize on electricity pond, solves electric automobile in going, and certain economize on electricity core produces the circumstances of opening a way and can not continuously drive and takes place, though the battery total voltage can reduce the voltage of a lesson battery this moment, the motor that still can the make electric automobile A certain amount of time that normally works the emergency braking circumstances can not appear to the lives and properties that make navigating mate are protected.
Description
Technical field
This utility model relates to the field of electric automobile, particularly relates to a kind of safe battery case used for electric vehicle.
Background technology
In electric automobile industry, owing in battery case, battery series-parallel connection is a lot, number of batteries is too much, existing battery unstable factor increases the most therewith, such as, when a certain economize on electricity core is due in normal work, there is a batteries that open loop state occurs, now, the discharge loop with external system of whole set of cells produces open circuit, and electric automobile will be unable to continue to travel.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of safe battery case used for electric vehicle, avoid the problem that in series connection, certain batteries open circuit causes system to work, solve electric automobile under steam, the situation that certain economize on electricity core produces open circuit and can not continue to travel occurs, although now battery total voltage can reduce the voltage of a batteries, but still the motor of electric automobile can be made normally to work the regular hour, do not have brake hard situation, so that the lives and properties of human pilot are protected.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of safe battery case used for electric vehicle, including BMS voltage acquisition port, BMS Control port and battery assembly module, multiple described battery assembly modules are connected between BMS voltage acquisition port and BMS Control port, described battery assembly module includes the first relay, the second relay and battery core, the first described relay and the second relay are connected in parallel, and described battery core is connected with the first relay and the second relay respectively.
In one preferred embodiment of this utility model, the quantity of described battery assembly module is 3 groups.
In one preferred embodiment of this utility model, the collection magnitude of voltage of described BMS voltage acquisition port is protection voltage.
In one preferred embodiment of this utility model, the pin output high level of described BMS Control port.
The beneficial effects of the utility model are: safe battery case used for electric vehicle of the present utility model, avoid the problem that in series connection, certain batteries open circuit causes system to work, solve electric automobile under steam, the situation that certain economize on electricity core produces open circuit and can not continue to travel occurs, although now battery total voltage can reduce the voltage of a batteries, but still the motor of electric automobile can be made normally to work the regular hour, do not have brake hard situation, so that the lives and properties of human pilot are protected.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the circuit block diagram of a preferred embodiment of this utility model safe battery used for electric vehicle case；
Reference is as follows: 1, BMS voltage acquisition port, and 2, BMS Control port, the 3, first relay, the 4, second relay, 5, battery core.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, this utility model embodiment includes:
A kind of safe battery case used for electric vehicle, including BMS voltage acquisition port 1, BMS Control port 2 and battery assembly module, multiple described battery assembly modules are connected between 2 mouthfuls of BMS voltage acquisition port 1 and BMS Control end, described battery assembly module includes the first relay the 3, second relay 4 and battery core 5, the first described relay 3 and the second relay 4 are connected in parallel, and described battery core 5 is connected with the first relay 3 and the second relay 4 respectively.In the present embodiment, the quantity of described battery assembly module is 3 groups.
Wherein, the collection magnitude of voltage of described BMS voltage acquisition port is protection voltage；The pin output high level of described BMS Control port.
Damaging when battery core 5 and form open circuit, it is protection voltage, now, BMS program trigger protection mode that BMS gathers magnitude of voltage, and now BMS Control pin output high level controls the first relay 3 corresponding to battery core 5 and closes；Battery core 5 in external connection, recovers the discharge loop of battery assembly module and external system by the second relay 4.
In sum, safe battery case used for electric vehicle of the present utility model, avoid the problem that in series connection, certain batteries open circuit causes system to work, solve electric automobile under steam, the situation that certain economize on electricity core produces open circuit and can not continue to travel occurs, although now battery total voltage can reduce the voltage of a batteries, but still the motor of electric automobile can be made normally to work the regular hour, do not have brake hard situation, so that the lives and properties of human pilot are protected.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
