Description
Technical Field
The utility model belongs to special place operation car power supply field, in particular to modular modularization group battery.
Background
Along with the rapid development of the electromotion of special field operation vehicles such as changing forklift oil into electricity and changing sanitation vehicle lead-acid into lithium electricity, the lithium battery industry is increasingly in vigorous demand as the upstream industry of power energy.
At present, most of power supplies of special field operation vehicles in the market adopt the design scheme of an integrated power supply system, the power supply system and the whole vehicle are bound and designed together, for example, an electric forklift with a picking load of 3.5 tons is matched with the integrated power supply system with the design model of 72V 320Ah, the installation size and various electrical interfaces on the whole vehicle correspond to the integrated power supply system one by one, and one vehicle type is customized with the integrated power supply system.
However, the integrated power system has many disadvantages, such as large volume, many components, and high degree of standardized operation, which may result in high cost for product development and development, and if a developed vehicle model cannot be produced in large quantity, no matter for the whole vehicle or the power system matching manufacturer, serious capital investment and shortage will be caused.
If the integrated power supply system is matched with the vehicle type which is continuously produced in batches, the development cost is reduced and profits are created along with the mass production, the product can be continuously produced, but the after-sale problem which is difficult to solve is along with the production, the integrated power supply system and the whole vehicle are bound to be designed, once the power supply system breaks down in the using process, firstly, the whole vehicle cannot normally work, and only can be transported to an after-sale service point by a trailer for maintenance, secondly, the larger the power supply module is, the more the structure technology is, the more the fault troubleshooting points are, the more point-to-point troubleshooting is needed during the maintenance, the after-sale maintenance strength is large, and the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a be different from integration electrical power generating system, the combination formula modularization group battery of troubleshooting and low-cost maintenance of being convenient for.
The combined modular battery pack comprises an electric quantity display, a coulometer, a plurality of module power supplies with the same quantity and a voltage display, wherein the voltage display is connected with the module power supplies in a one-to-one mode, the module power supplies are connected in parallel through parallel wiring harnesses, the parallel wiring harnesses are connected into a positive pole and a negative pole of a whole vehicle, and the electric quantity display, the coulometer and the module power supplies which are connected in parallel are connected in series.
The working principle of the scheme is as follows: according to the voltage platform, the driving mileage and the power requirement of the whole vehicle, a module power supply matched with a proper model is matched with the whole vehicle for parallel use, each group of module power supply is matched with a voltage display, the charge quantity and the health state of a battery pack can be visually evaluated, after the module power supply is installed on the whole vehicle, all module batteries are connected in parallel by using a parallel wiring harness and are connected to the positive electrode and the negative electrode of the whole vehicle, then a coulometer and a power display are installed, the power display is matched with the coulometer, and in the running process of the vehicle, the coulometer can visually find out the running state of a battery system.
During after-sale maintenance, the battery pack is charged and tested, the coulometer detects the electric capacity, data are displayed through the electric quantity display, the full electric capacity on the electric quantity display is observed when the battery pack is full, if the full electric capacity is larger than an initial designed value, for example, the initial full electric capacity designed value is 320Ah, the single-group module battery capacity is 40Ah, the full electric capacity is lower than 280Ah or lower when the maintenance is carried out, one group or multiple groups of module battery faults can be preliminarily judged, at the moment, next-step investigation is carried out, namely, a discharging test is carried out on the battery system, the voltage display matched with the module power supply is observed in the discharging process, the voltage reduction condition can be known, if the voltage of which module power supply is not reduced or jumps back and forth or the voltage difference between the voltage and other module power supplies is more than 2V, the power supply module of the group is indicated to be in fault, and the fault battery can be returned to the factory for maintenance.
The beneficial technical effect of this scheme is:
based on modular modularization group battery in this scheme can be according to the market demand, the design covers 12V, 24V, 48V, 60V, the group battery of series voltage platforms such as 72V, according to the standardized electric core in market, the design covers the group battery of different capacities such as 5AH, 10AH, 20AH, the supporting parallelly connected pencil of design adopts the standardized connector butt joint in market with parallelly connected group battery, the always positive always negative end of parallelly connected pencil, correspond the part butt joint according to the interface lectotype of whole car, can accomplish group battery and whole car driving system seamless connection. The configuration of the galvanic pile is optimally carried out according to the minimum dimension of the battery pack, and the standardized connecting parts are matched to form an autonomous standardized modularized battery pack product, so that the battery pack is suitable for different requirements of the market. The technology solves the problems of complex structure technology and high development cost of the customized and developed integrated power supply system, fault troubleshooting is simple and convenient, processing efficiency is high, a faulted module power supply is replaced in a targeted mode, and maintenance cost is reduced.
Further, the voltage of each module power supply is consistent with the use voltage of the whole vehicle.
