When battery cohort 15 is in the time that needs are balanced, first BMS management system cuts off the power supply output of battery cohort 15, under the state that there is no electric current output, realize 15 equilibriums of battery cohort, output is now zero potential, disconnect at anodal moving contact 23a and anodal output contact 24a, the moment of contact 25a contact balanced with positive pole, negative pole moving contact 23b and negative pole output contact 24b disconnect, the moment of contact 25b contact balanced with negative pole can not produce action spark, but the now parameter of each battery cohort 15 inconsistent, the battery cohort 15 of prior art (battery cohort in parallel time) in the time of equilibrium has a large electric current moment and flows to electronegative potential from high potential, contact can produce discharge spark in the time of closure, and then ablation contact affects the working life of battery cohort 15, and the present embodiment is in the time of balanced operation state, the quick acting that insulated tension pole 31 is realized under the effect of back-moving spring 33, the moment of having realized contact switches, balanced end, BMS management system is sent instruction, reducing motor 43 drags driver plate 34 and rotates, driver plate 34 engages sheave 35 and rotates, insulated tension pole 31 stirs anodal moving contact 23a and negative pole moving contact 23b is transformed into normal power source output, now because power supply is exported in dissengaged positions, therefore anodal moving contact 23a and negative pole moving contact 23b can not produce spark in the time of action, when completing after output state conversion, BMS management system connects the power supply output of controlling energising pond cohort 15, make the state of this device in normal work, and then eliminate the short defect of above-mentioned working life.
In the present embodiment, the rotation of sheave 35 is to engage rotation by driver plate 34 to realize, and the rotation of driver plate 34 is dragged by reducing motor 43, the rotation of reducing motor 43 is realized by the control of BMS management system, by being set, BMS management system often sends a program control instruction, reducing motor 43 drags driver plate 34 and rotates a circle, thereby has realized normal output and the balanced conversion of battery cohort 15.
As shown in Fig. 1 and Fig. 8, described pull bar drive unit is connected with battery module state indicating device, described battery module state indicating device comprises by rotating shaft 47 and is hinged on the indicating arm 46 on described equalizer switch seat 21, described insulated tension pole 31 is provided with indicating arm allocating slot 49, the lower end of described indicating arm 46 stretches in described indicating arm allocating slot 49, extend to described module upper cover 2 upper end of described indicating arm 46, and described module upper cover 2 is provided with the form 48 of being convenient to observe described indicating arm 46 positions.In the time that insulated tension pole 31 moves, drag indicating arm 46 and 47 realize swing around the shaft, by the transparent window 48 of module upper cover 2, can observe battery cohort 15 is in power supply output state or in equilibrium state, this is very important in the time that battery cohort 15 is installed.
The present embodiment only provides the technical scheme of single battery module, in practical application, can be according to the requirement of the voltage of motor vehicle and capacity, respectively multiple group of battery modules are combined, each battery module is cascaded by work positive pole and work negative pole simultaneously, and each battery module is connected in parallel by balanced positive pole and balanced negative pole, so just can realize multiple battery module co-operation and equilibrium.In described module, cover to be also provided with and be convenient to the communication interface that is connected with described battery management system, certainly this communication interface is according to the difference of electric vehicle structure, can be arranged on as waited other positions in modular tank, battery management system can be arranged on driver's cabin or other position of electric automobile, in the accompanying drawing of the present embodiment, does not show.
Because this device in use can arrange several battery modules, can there is certain parameter differences along with using between each battery module, can use BMS management system to carry out unified management to this difference, the concrete function that BMS management system possesses is as follows:
(1) accurately estimate the state-of-charge (SOC) of battery cohort: i.e. the dump energy of battery module, guarantee that SOC maintains in rational scope, prevent owing to overcharging or overdischarge causes damage to battery module, and show at any time the SOC of battery module.
(2) dynamic monitoring: battery module in charge and discharge process, the total voltage of the terminal voltage of every cell in Real-time Collection battery module, temperature, discharging current and battery module; Meanwhile, can detect in time the situation of cell, keep reliability and the high efficiency of whole battery module.
(3) equilibrium of cell apparatus: keep in battery cohort each cell equilibrium at consistent state, be controlled at by BMS management system in time of setting whole battery module is carried out to equilibrium.
(4) the working temperature control of cell apparatus: because battery module can produce high temperature when the high power charging-discharging, excess Temperature can affect the normal use of battery module, in the time that battery module temperature rise exceedes 45 ℃, the radiator fan starting on module housing is lowered the temperature to battery cohort, to keep battery module to be operated in optimum Working.
In sum, the connection in series-parallel of equalizer switch sets of contacts conversion is to send instruction by BMS management system, and the work of pull bar drive unit, drives insulated tension pole parallel, and insulated tension pole stirs by moving contact shell fragment that the action of equalizer switch sets of contacts realizes.
Each battery module is equipped with balanced both positive and negative polarity joint pin, after composition module cohort, balanced positive and negative terminals is connected respectively, so just can realize the equilibrium of whole cohort, when after battery module cohort work a period of time, it being carried out to equilibrium, greatly extend the useful life of battery.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
