Abstract
The utility model provides a battery charging management system for underwater mine cars. The system provided by the utility model structurally comprises a main control unit BCU for controlling each part of the battery charging management system to work in a coordinating way, a main battery pack charging unit and an auxiliary battery pack charging unit. The two charging units are both controlled by the main control unit BCU. The system is enabled to charge two battery packs with different capacities without increasing the using control difficulties and meanwhile never overcharge the battery packs. Meanwhile, the internal information about the two different battery packs is read by the main control unit BCU through different BMUs. The system can thus achieve unified outputs after the processing and share the information. Use experiences of users are enhanced. After-sale maintenance is also benefited. Meanwhile, only one main control unit BCU is required. The cost of the system is thus lowered.
Description
Technical field
The utility model belongs to field of batteries, is specifically related to a kind of ore deposit under water Vehicular battery charging management system.
Background technology
Current battery is many technical fields energy commonly used.And some needs the power supply of two different voltages when needing battery as dynamical system.For example mine car electric power system under water needs one to provide power supply A-battery group for mine car provides the power battery pack of power and one for other low pressure auxiliary equipment systems.Need to be the batteries charging of two different voltages simultaneously during charging, because two battery capacity differences, so the required time of charging is different.
Existing battery charging management system is generally a main control unit BCU and a power brick charhing unit.The power brick charhing unit comprises several charging devices that link to each other with BCU from control unit B MU, by charging CAN that link to each other with BCU by inner CAN.During the power brick charging, adopt a charger to communicate, only used one tunnel inner CAN control charging process; Prescribe a time limit when maximum monomer voltage reaches on the charging voltage, battery management system disconnects relay, prevents that battery pack from overcharging.
If with a battery charging management system, another battery pack can't be full of certainly when a battery electric quantity is sufficient; If with two battery management systems, then can't carry out management by synchronization, strengthened and used the control difficulty, increased cost.
The utility model content
For solving the problems of the technologies described above, the utility model provides the ore deposit under water that can manage simultaneously two different voltage battery groups Vehicular battery charging management system.
The utility model is realized in the following way:
A kind of ore deposit under water Vehicular battery charging management system has the main control unit BCU that controls the co-ordination of battery charging management system each several part.This battery charging management system comprises main battery bag charhing unit and boosting battery bag charhing unit, and two charhing units are controlled by this main control unit BCU.
Described main battery bag charhing unit and boosting battery bag charhing unit include main control unit BCU, by inner CAN bus be connected with main control unit BCU from control unit B MU and the charging device that is connected with main control unit BCU by charging CAN bus, battery pack to be charged is connected with charging device, at battery pack to be charged and the contactor that is provided with control charge circuit break-make between charging device is connected.
As further improvement in the technical proposal, be preferably 2 from dummy cell BMU quantity in the described main battery bag charhing unit.
As further improvement in the technical proposal, on main control unit BCU, link the display device that is connected to demonstration information by CAN.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model can be the batteries charging of two different capabilities when not increasing use control difficulty and can not overcharge.
2, because the utility model only needs a main control unit BCU, so with respect to the prior art of two BCU of needs, save cost.
3, because main control unit BCU reads the internal information of two different battery pack by different BMU, can process rear unified output, realize information sharing, be more conducive to the user and use and after-sales service.
Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment.
Among the figure, 1, main control unit BCU; 2, main battery bag charhing unit; 3, boosting battery bag charhing unit; 4, from control unit B MU; 5, charging device; 6, contactor; 7, CAN card; 8, display device.
Embodiment
Defective for prior art exists is described in further detail of the present utility model for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of ore deposit under water Vehicular battery charging management system has the main control unit BCU1 that controls the co-ordination of battery charging management system each several part.This battery charging management system comprises that main battery bag charhing unit 2 and boosting battery bag charhing unit 3, two charhing units control by this main control unit BCU.
Main battery bag charhing unit and boosting battery bag charhing unit include main control unit BCU, by inner CAN bus be connected with main control unit BCU from control unit B MU4 and the charging device 5 that is connected with main control unit BCU by charging CAN bus, battery pack to be charged is connected with charging device, at battery pack to be charged and the contactor 6 that is provided with control charge circuit break-make between charging device is connected.Wherein, the quantity from control unit B MU in the main battery bag charhing unit is 2.And, on main control unit BCU, be connected with the display device 8 of demonstration information by CAN card 7.
The main battery bag charhing unit course of work is as follows: charging device is the charging of band rechargeable battery set; Detect battery pack information and by inner CAN battery pack information is passed to main control unit BCU from control unit B MU, BCU is according to battery pack information control charging device and contactor.When the maximum monomer voltage of battery pack reaches on the charging voltage in limited time, main control unit control charging device stops charging, prevents that battery pack from overcharging.
The boosting battery bag charhing unit course of work is as follows: charging device is the charging of band rechargeable battery set; Detect battery pack information and by inner CAN battery pack information is passed to main control unit BCU from control unit B MU, BCU is according to battery pack information control charging device and contactor.When the maximum monomer voltage of battery pack reaches on the charging voltage in limited time, main control unit control charging device stops charging, prevents that battery pack from overcharging.
The CAN cartoon is crossed inner CAN and is obtained two battery pack informations to be charged from BCU, and is shown in display device.
During work, because two power brick charhing units only have BCU to share, thereby the course of work of two power brick is separate, is independent of each other, thereby can guarantee to realize the Synchronization Control to two charging circuits to two complete completely chargeds of different battery pack simultaneously.Because the utility model only needs a main control unit BCU, so with respect to the prior art of two BCU of needs, save cost.And main control unit BCU reads the internal information of two different battery pack by different BMU, can process rear unified output, realizes information sharing, is more conducive to the user and uses and after-sales service.
The utility model can be two different batteries chargings except above-mentioned, can also realize the conventional func such as voltage detecting, current detecting, temperature detection, SOC estimation, fault alarm.
The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
