Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will make needed for embodiment description Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings Accompanying drawing.Wherein:
Fig. 1 is the structural representation of the equalizing system of the electricity of first embodiment of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on this Embodiment in invention, it is every other that those of ordinary skill in the art are obtained under the premise of performing creative labour is not made Embodiment, belongs to the scope of protection of the invention.
Shown in Figure 1, Fig. 1 is the structural representation of the high pressure Detection & Controling main controller of first embodiment of the invention Figure.As shown in figure 1, the high pressure Detection & Controling main controller 1 disclosed in the present embodiment includes control signal input 11.
Wherein, the integrated main control module of high pressure Detection & Controling main controller 1 and high pressure detection module, i.e., by main control module and height Pressure detection module is designed to high pressure Detection & Controling main controller 1;High pressure Detection & Controling main controller 1 is used to directly gather battery pack The integral insulation state of 2 total voltage, electric current or battery pack 2.Wherein, battery pack 2 includes multiple cells, multiple monomers Battery is connected in series, and cell can be lithium-ions battery, lithium polymer battery, lead accumulator, nickel-cadmium cell, ni-mh electricity The batteries such as pond.
When control signal input 11 receives control signal, high pressure Detection & Controling main controller 1 is according to control signal Gather the integral insulation state of total voltage, electric current or the battery pack 2 of battery pack 2.Wherein, the total voltage of battery pack 2, electric current or The integral insulation state of person's battery pack 2 includes:The voltage and temperature of cell, total voltage, charging or discharging current and insulation resistance value.
Alternatively, high pressure Detection & Controling main controller 1 also includes collection terminal 12, and high pressure Detection & Controling main controller 1 passes through Collection terminal 12 gathers the integral insulation state of total voltage, electric current or the battery pack 2 of battery pack 2.
Integral insulation shape of the high pressure Detection & Controling main controller 1 also to the total voltage of battery pack 2, electric current or battery pack 2 State is handled, to obtain the state of each item data, to ensure the electric automobile using the high pressure Detection & Controling main controller 1 Power in real time, is reliably and safely run.
Wherein, during battery pack 2 is discharged, high pressure Detection & Controling main controller 1 judges the total voltage mistake of battery pack 2 Low, discharge current is excessive or during insulation fault, such as high pressure Detection & Controling main controller 1 judges that the total voltage of battery pack 2 is small It is more than Second Threshold in the discharge current of first threshold, or battery pack 2, then the cut-out of high pressure Detection & Controling main controller 1 battery The discharge loop of group 2, to protect battery pack 2, it is to avoid the transient discharge of battery pack 2.During battery pack 2 charges, high pressure inspection When survey judges the too high total voltage of battery pack 2, excessive charging current or insulation fault with control main controller 1, for example high pressure is examined Survey and judge that the total voltage of battery pack 2 is more than the 3rd threshold value with control main controller 1, or the charging current of battery pack 2 is more than the 4th Threshold value, then high pressure Detection & Controling main controller 1 cuts off the charge circuit of battery pack 2, so that the stopping charging of battery pack 20, and avoid Battery pack 2 is overcharged, and extends the life-span of battery pack 2.
Compared with prior art, high pressure Detection & Controling the main controller 1 integrated main control module and height disclosed in the present embodiment Detection module is pressed, the structure of prior art design is reduced, it is convenient to install, design space is saved, cost is reduced;In addition, it is to avoid Lose the failure of communication between main control module and high pressure detection module, and then avoid loss of data, improve stability;In addition, High pressure Detection & Controling main controller 1 directly gathers each item data, and each item data can be monitored in real time, exactly, is efficiently controlled Output, improves the service efficiency of battery pack 2.
