Description

Quick change system and method for electric vehicle standardized battery module
Technical Field
The invention relates to the technical field of automobiles, in particular to a quick replacement system and a quick replacement method for a standardized battery module of an electric vehicle.
Background
With the continuous development of social economy, the living standard of people is continuously improved, the private car purchasing is fashionable, and China enters or is about to buy the car for all people. With the further increase of the automobile industry popularity, the automobile output and sales volume in China will be further increased in the future. At present, the fuels used by automobiles are mainly gasoline and diesel oil, which belong to non-renewable energy sources, and with the increasing of the automobile holding amount year by year, the problems of environmental pollution caused by automobile emission and gradual shortage of petroleum resources are not ignored, so that various alternative fuels are also widely applied. In recent years, new energy automobiles develop rapidly, and particularly, electric automobiles driven by stored power have the advantages of simple structure, less maintenance, low use cost, low noise, low energy consumption and the like, and are greatly supported by national industrial policies, and people gradually accept travel modes of the electric automobiles. The electric automobile as a new energy vehicle has the characteristics of low noise, high energy utilization efficiency, no mobile waste discharge and the like, and becomes one of strategic emerging industries which are key supports in China.
Energy supply is an important link in the industry chain of electric automobiles, and the energy supply mode is closely related to the development of the electric automobiles. Currently, the energy supply of the electric vehicle can be classified into 2 modes of plug-in charging and battery replacement, wherein the plug-in charging can be classified into slow charging and fast charging. Under the plug-in charging mode, the battery problem restricting the development of the electric automobile is particularly prominent: on one hand, the initial investment cost for purchasing the battery is too large, and generally accounts for more than half of the cost of the electric automobile body, and the expensive battery cost hinders the popularization of the electric automobile to a great extent; on the other hand, the charging time is too long, the slow charging is generally 4-5 hours, even if the charging is fast, 0.5 hour is needed, and the convenience of obtaining energy compared with the oiling or gas filling of the current traditional energy automobile can not meet the needs of people. Meanwhile, the quick charging has great damage to the battery, so that the service life of the battery is sharply reduced, and the cost of the battery of the electric automobile is further increased actually. In addition, in the plug-in charging mode, the charging load of the electric vehicle has significant space-time randomness, and adverse effects can be brought to the operation and planning of the power grid.
On the other hand, a battery replacement mode based on battery leasing and large-scale centralized charging are combined to form a commercial technical mode with competitive development of the current electric automobiles. The battery leasing mode is adopted, and the initial investment cost of the battery is borne by a power grid company, so that the initial vehicle purchasing cost of a user can be obviously reduced; secondly, the battery can be intensively charged in a slow charging mode, so that the problem of short service life of the battery caused by quick charging is avoided; thirdly, the battery replacement process can be completed within several minutes by adopting a battery replacement mode, and the convenience is not inferior to that of a conventional energy automobile; and the fourth step of carrying out centralized charging management on the batteries can avoid adverse effects on the operation of a power grid caused by random charging of a large-scale electric automobile, and even can carry out optimized operation of battery charging under a unified management framework according to the needs of the power grid, so that green energy loss can be avoided, and the power generation cost of renewable energy sources is reduced.
The advantages of the electric vehicle battery replacement mode, the safety of the battery, the application of the trough power and the like can be effectively controlled are gradually recognized and paid attention to, the development of the battery replacement mode is restricted by the requirement of quick and convenient operation and the cost required to be invested in the frequent battery replacement period, and the popularization of the electric vehicle battery replacement mode are influenced.
The existing quick-change system adopts manual battery pack handling, generally, the battery pack handling needs to be lifted to a certain height to ensure that a battery module is separated from a motor board connected with the system, and then all the battery packs are handled to a logistics turnover vehicle one by one, and due to the fact that the number of batteries is large and the weight is large, the labor intensity of battery replacement work is high, and the efficiency is low; alternatively, the battery module is integrally carried by dedicated automatic carrying equipment, e.g.http：//www.potevio.com/g412/s1180/ t1400.aspxHowever, the method has high investment cost in the earlier stage, and requires a large operation space, and particularly requires different battery modules for different vehicle types, which is not favorable for standardized production and management of the battery modules.
