The charging module comprises a plurality of parallel-connection charging modules and a charging control module, one end of the charging module is the input end, the input end of the charging module is connected with the alternating current bus, the other end of the charging module is the output end and is connected with an inverter, the inverter is connected with the direct current bus, the charging module achieves a current-sharing output and automatic equalization control technology by adopting multiplexed output coordination and power intelligent assembly, damage to a battery of the electric automobile is reduced, and the charging module is small in size and high in power and rapidly charges the electric automobile.

Description

Technical field [0001] The invention relates to a charger device, in particular to an intelligent integrated charger device for electric vehicles. Background technique [0002] Domestic research on charging facilities has been launched. At present, there are mainly two methods of charging and switching. The charging method is limited to the construction of large-scale charging stations. The simple combination of multiple chargers is used in the rapid charging of electric vehicle power battery packs. The charging mode of normal charging and the setting of charging parameters are still in the empirical setting and exploration stage. In the charging process, the research on the application of battery temperature, insulation, overcharge alarm and protection needs to be in-depth. [0003] The Chinese patent published by the State Intellectual Property Office on March 20, 2013 (application number 201220239210.2, and the title of the invention is Integrated Smart Charging System), and the...

Problems solved by technology

[0004] 1. The current chargers use the field bus to communicate with the background. In this way, a large number of cables need to be laid, and the communication is prone to interference. It is easy to cause misoperation of the charger and damage the charger and the battery. Not only the cost is high, Moreover, laying cables requires a lot of manpower, because the cables laid are very long, and when a fault occurs, it is not easy to find out the fault location;

[0005] 2. There is no reasonable ventilation duct in the existing charger, which causes the temperature inside the charger to be too high. If the inner temperature of the charger in the charger is too high or too low, it is easy to cause damage to the components in the charger and affect The life of the charger, in order to prolong the life of the charger, keep the temperature and humidity inside the charger within a controllable range, since the charging module and the DC output module are responsible for charging the charger, a lot of heat will be generated during the charging process, If the heat is not removed in time, it will not only affect the life of the charging module and the DC output module, but also affect the charging efficiency of the charger;

[0006] 3. In the prior art, the integration of the electric vehicle charger and the charging pile is separated, and there is no monitoring system and monitoring method involved in the integrated charger, and the existing monitoring system can only collect a power of the charger The data of the output port cannot collect the data of multiple power output ports of the charger, and it does not propose how to process the data of multiple power output ports;

[0007] 4. The current electric vehicle charging piles need to build charging stations, and there are more and more electric vehicles, and multiple charging stations need to be built in a city to meet the needs. However, the establishment of charging stations not only covers a large area, but also requires specific places Established, and cannot be moved according to people's needs, so people have a lot of trouble charging electric vehicles, and can only go to specific places to charge electric vehicles;

[0008] 5. The existing integrated charger is prone to explosion after running for a period of time in bad weather. The explosion of the charger will bring great danger to the safety of personnel and the electric vehicles being charged. It will not only waste costs, but also damage national property. cause great loss

[0009] In summary, so far there are no related patents and papers to solve the above problems
