Embodiment
A kind of battery management protective device as shown in Figure 1; include device box body 1; device box body 1 is provided with lid; its special feature is: the side of device box body 1 of the present invention is provided with battery and is connected terminal 2, and this battery is connected input terminal 2 being connected with and being separated control assembly 3.Meanwhile, the main output being separated control assembly 3 connects the input of battery management control assembly 4.Further, consider the stability of overall work, be separated the secondary output of control assembly 3 and be connected with load with being connected terminal 5 with the output of battery management control assembly 4 simultaneously.Under normal circumstances, the power consumption of battery management control assembly 4 is at milliampere, and the power consumption being separated control assembly 3 is low to microampere.
In conjunction with the present invention one preferably execution mode, the main output being separated control assembly 3 connects the input of battery management control assembly 4 by home court advamtageg control assembly 6.Further, the output of battery management control assembly 4 is provided with secondary field effect control assembly 7 with load with being connected between terminal 5, improves follow-up control ability.
Further, consider that some electricity consumption assembly there will be vibrations or carrying, be provided with separate accommodation frame 8 in device box body 1, separation control assembly 3, battery management control assembly 4 are all arranged on and hold in frame 8.Like this, a suitable location can be carried out, the assembly of the inside will be caused to occur unnecessary loosening because of applied external force.Further, consider the facility of wiring, prevent wire and be wound around the process affecting assembly, avoid occurring unnecessary electromagnetic interference simultaneously, hold frame 8 and be provided with trough.
Meanwhile, consider the facility of manufacture, home court advamtageg control assembly 6 and secondary field effect control assembly 7 are field effect transistor.Further, in order to improve overall firmness of the present invention, in device box body 1, reinforcement 9 is provided with.Certainly, in order to promote overall sealing, preventing entering of external dust and steam, affecting the work of assembly, between device box body 1 and lid, be provided with sealing ring.
From implementation process of the present invention, the parameter such as voltage, electric current, temperature of battery can be monitored the moment, stop the discharge and recharge of battery when temperature is too high, stop corresponding current channel when electric current is excessive, stop charge tunnel when overtension, stop discharge channel when undertension.When cell voltage difference is excessive, balance to each batteries.
Specifically, when after the under-voltage protection voltage that the voltage of battery component 10 sets lower than battery management control assembly 4, secondary field effect control assembly 7 is converted to off state from opening state by battery management control assembly 4, is separated by load component with battery.And when the voltage of battery component 10 is lower than after being separated under-voltage protection voltage that control assembly 3 sets, be separated control assembly 3 and home court advamtageg control assembly 6 is transformed into off state from conducting state, thus battery to be separated with battery management control assembly 4.After this outside power consumption of battery component 10 is only and is separated control assembly 3.
Also can be found out by reference to the accompanying drawings by above-mentioned character express, after adopting the present invention, when can not supplement electricity in time after battery component long term storage and short of electricity, greatly can reduce the risk that the overdischarge of the battery degree of depth causes permanent damages.Meanwhile, simple structure of the present invention, is easy to manufacture, and can adapt to most electricity consumption device and use.
Certainly, above is only embody rule example of the present invention, does not constitute any limitation protection scope of the present invention.In addition to the implementation, the present invention can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
