Referring to fig. 4, fig. 4 is a schematic flow chart illustrating a method for assisting in replacing a battery of an automobile according to an embodiment of the present invention. The method is applied to the battery test apparatus 100, and as shown in fig. 4, the method includes:
s10, acquiring vehicle identification information of the automobile;
the controller 40 communicates with the vehicle 200 via the interface module 60, and the controller 40 may obtain vehicle identification information, including in some embodiments the VIN code and/or the MMY code, from a system of the vehicle 200. The VIN code is unique identification information of the automobile, and includes various information related to the automobile, such as country, manufacturer, engine model, automobile type, year, and the like, and the MMY code includes manufacturer, automobile type, and year, so that the automobile type of the automobile can be determined by acquiring the automobile identification information of the automobile and analyzing the automobile identification information.
The VIN code or the MMY code may also be obtained by inputting, for example, the VIN code is input through the signal input module 70 of the battery detection device 100, the VIN code may be a vehicle identification code of 17 bytes, and after the vehicle identification code is input, the vehicle type of the vehicle may be determined according to the vehicle identification information.
S20, acquiring the position information of the battery of the automobile, the battery model selection method matched with the automobile and the battery replacement guide according to the vehicle identification information;
the position information of the battery of the automobile is the installation position of the battery on the automobile, and the installation position of the battery may be different for different automobile types.
The battery matched with the automobile means that the type and specification of the battery are suitable for the automobile type, and the requirements on the battery are different due to different automobile types, so the selection method of the battery is different for different automobile types. As for the battery type, general automotive batteries are classified into Floded/Regular, EFB, AGM/VRLA, GEL. The EFB battery and the AGM battery are generally used for automobiles with starting functions, can support frequent starting of an engine, and are long in battery cycle life, the AGM battery is excellent in this respect, the common Flooded battery cannot be used for starting and stopping a system, otherwise the battery life is seriously influenced, the EFB battery and the Flooded battery are good in high-temperature resistance and can be generally mounted in an engine compartment, the GEL storage battery electrolyte is GEL, and compared with the AGM battery, the GEL battery generally has longer service life and better deep charge-discharge cycle capability.
Since the requirements for the battery are different when the battery is installed in different positions in the automobile, the engine compartment generally needs to be resistant to high temperature, floded and EFB can be installed in the engine compartment, but AGM generally needs to be installed in a seat or a trunk, and the geographical area where the automobile is located also affects the type of the battery, for example, the CCA (cold starting current) of the battery and the capacity of the battery should be increased appropriately in cold regions. Therefore, the appropriate battery can be replaced for the automobile according to the battery type selection method corresponding to different automobile models and by combining the battery type, the battery installation position, the geographical area and other factors, so that the use requirement of the automobile can be better met.
In some embodiments, the battery replacement guide includes a battery removal method, a method for replacing a battery without powering down, and a replacement notice.
In the embodiment, on the basis of determining the position information of the battery of the automobile, the battery disassembling and assembling method is combined, so that a maintainer can conveniently perform battery testing and battery disassembling and assembling, and the battery testing efficiency or the battery disassembling and assembling efficiency can be improved.
For a specific vehicle model, the method for replacing the battery without power interruption can be as follows: the spare battery is connected to the outside of the automobile in parallel through the power-off memory, the power-off memory is provided with two clamps which are respectively clamped on the positive electrode and the negative electrode of the battery, the other end of the power-off memory can be inserted into the OBD connector of the automobile or connected onto the cigarette lighter to realize power supply of the double batteries, after the step is completed, the battery on the automobile is disconnected, the new battery is replaced, and finally the power-off memory is disconnected, so that the battery replacement is completed. The method generally requires two persons to operate, and the anode and the cathode are not contacted with other parts on the vehicle to cause short circuit to cause accidents due to extreme care.
The change notice may be: when the storage battery is disassembled and assembled, the storage battery is firstly negative and then positive during disassembly, the assembly is opposite, and if the storage battery is a double battery, the storage battery is firstly main and then auxiliary; and (4) checking whether the positive and negative poles/pile heads of the battery are dirty or not, and cleaning if necessary.
