Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
If Fig. 1 is the structural representation for being used for system electric under array according to embodiment of the present utility model realization
Figure, array include including the multiple of series connection by bus multiple battery pack B1~Bn in parallel, each battery pack B1~Bn
Battery unit, in figure, the system includes：Controller (not shown)；Be connected to it is between each battery pack B1~Bn and bus,
Major loop and subsidiary loop in parallel；
Subsidiary loop includes：
Aid in gate-controlled switch S1~Sn；
Current limiting element R1~Rn, the size of current of subsidiary loop is flowed through for limiting；In this embodiment, current limliting member
Part R1~Rn can be fixed value resistance, or variable resistor.
Major loop includes main gate-controlled switch K1~Kn；
Controller is used for：
In array before electricity under bus, each auxiliary gate-controlled switch S1~Sn is closed；
Each main gate-controlled switch K1~Kn is disconnected after the cycle very first time；
Each auxiliary gate-controlled switch S1~Sn is disconnected after the second time cycle.
In an embodiment of the present utility model, the cycle very first time can be 1 second, or 2 seconds.This
Two time cycles can be 1 second, or 2 seconds.The cycle very first time and the second time cycle do not have dependency relation, because
This, very first time periodic quantity provided by the utility model and the second time cycle value can mutual permutation and combination, such as at first
Between the cycle can be 1 second in the case of, the second time cycle can be 1 second or 2 seconds.
Fig. 2 is the workflow for being used for method electric under array realized according to embodiment of the present utility model
Figure.In figure, the workflow comprises the following steps：
In step slo, in array before electricity under bus, each auxiliary gate-controlled switch S1~Sn is closed.Such as Fig. 1
Shown, the electric current between array and bus is general bigger before lower electricity.Close each auxiliary gate-controlled switch S1~Sn
Afterwards, subsidiary loop turns on, and flows through the electric current in major loop and reduces because of the shunting of subsidiary loop.Controller control closure is each
Gate-controlled switch S1~Sn is aided in, the controller can select microcontroller, can also select battery management system (Battery
Management System, BMS).Auxiliary gate-controlled switch S1~Sn can be at least one of following from including：Relay
Device, triode and FET.
In step S20, each main gate-controlled switch K1~Kn is disconnected after the cycle very first time.Subsidiary loop turns on
Afterwards, the size of current between major loop and subsidiary loop can produce fluctuation in a short time, the interval cycle very first time be then to
Electric current between major loop and subsidiary loop is adjusted.The cycle very first time can select 1 second, can also select 2 seconds.Should
Main gate-controlled switch K1~Kn can be at least one of following from including：Relay, triode and FET.
In step s 30, each auxiliary gate-controlled switch S1~Sn is disconnected after the second time cycle.With step S20 phases
Seemingly, after major loop disconnects, the size of current in subsidiary loop can produce fluctuation in a short time, be spaced for the second time cycle and be then
It is adjusted to the electric current for flowing through subsidiary loop.Second time cycle can select 1 second, can also select 2 seconds.
As shown in figure 1, array is composed in parallel by n battery pack B1~Bn, in each subsidiary loop, there is master controllable
K1~Kn is switched, each subsidiary loop includes the current limiting element R1~Rn and auxiliary gate-controlled switch S1~Sn of series connection, in addition, this is
Controller (not shown) is also included in system, the controller is used for the workflow for controlling the system.
When electric under array, close first all auxiliary gate-controlled switch S1~Sn (now main gate-controlled switch K1~
Kn is in closure state), subsidiary loop shunts to the electric current for flowing through major loop, reduces the size of current for flowing through major loop.
After the cycle very first time, the electric current flowed through in major loop and subsidiary loop tends towards stability, and now disconnects main gate-controlled switch K1
~Kn.After the second time cycle, the electric current flowed through in subsidiary loop tends towards stability, now disconnect auxiliary gate-controlled switch S1~
Sn.Due to shunting the presence of mechanism so that it is smaller to flow through the electric current of major loop and subsidiary loop, therefore will not be in disconnection
When there is the situation of spark, avoid main gate-controlled switch K1~Kn and aid in gate-controlled switch S1~Sn sintering hidden danger, extend
Its service life.
Pass through above-mentioned technical proposal, it is provided by the utility model a kind of to be used under array that electric system be in battery
First the electric current between array and electrical appliance is reduced when electric under array, avoids and is disconnected between array and electrical appliance
When due to caused by electric current is excessive produce electric spark the problem of, solve the problems, such as that main switch easily burns in the prior art,
Extend the service life of array interface.
Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing
Detail in above-mentioned embodiment, can be to skill of the present utility model in range of the technology design of the present utility model
Art scheme carries out a variety of simple variants, and these simple variants belong to the scope of protection of the utility model.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance
In the case of shield, it can be combined by any suitable means, in order to avoid unnecessary repetition, the utility model is to each
The possible combination of kind no longer separately illustrates.
In addition, it can also be combined between a variety of embodiments of the present utility model, as long as it is not disobeyed
Thought of the present utility model is carried on the back, it should equally be considered as content disclosed in the utility model.
