Specific embodiment
Below in conjunction with attached drawing, by the way that a preferable specific embodiment is described in detail, the utility model is done and is further explained
It states.
As shown in Figure 1, the utility model proposes a kind of connection in series-parallel battery pack system of band limping function, it includes：It is more
Group battery pack 3, is respectively adopted multipair positive and negative contactor 41,42 and forms battery pack with parallel way；It is multiple from control module 2, respectively
Connect multiple battery packs 3 and multipair positive and negative contactor 41,42；Always just, total negative contactor 51,52, connect battery pack respectively
Positive and negative electrode；Main control module 1, connect respectively it is multiple from control module 2 and it is total just, total negative contactor 51,52.
As shown in Figure 2,3, each battery pack 3 includes：Multiple battery clusters 31 connected with conducting wire 6.Each battery cluster 31 wraps
Contain：Several bus-bars 312；Multiple single battery cores 311 are connected in parallel by several bus-bars 312.
The 1 model BMU V4.6b of main control module, from control 2 model LECU-EV5.0-12S of module.From control module
2 are responsible for monitoring 3 state of battery pack, such as：Voltage, temperature etc., main control module 1 are responsible for according to each battery pack 3 uploaded from control module 2
State judge the working condition of entire battery pack.Main control module 1 is communicated, communicates with external module and controlled with from control module 2
System is total just, always closure is opened and moved to negative contactor 51,52 dynamic circuit breakers.
Under normal drive mode, all contactors 41,42,51,52 are in closure state, when certain group battery pack 3 occurs
After failure, failure is reported to main control module 1 by this group of battery pack 3 immediately from control module 2, and sends lower electric request instruction to master
Control module 1.Main control module 1 is received after the lower electricity request of control module 2, according to battery pack current state, is determined whether
3 times electricity of fail battery group, and send lower electricity and instruct to fail battery group 3 accordingly from control module 2.When fail battery group 3 is from control
After module 2 receives 1 time electricity instruction of main control module, the positive and negative contactor 41,42 of the group is disconnected immediately.It is and other in normal shape
Battery pack 3 in state continues to power to vehicle, and vehicle is made to operate under limping pattern.
Although the content of the utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as the limitation to the utility model.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the scope of protection of the utility model should be by appended
Claim limit.
