Embodiment 2

[0053] The automatic coding system of the box-type quick-change battery in this embodiment is a further improvement on Embodiment 1. specifically:

[0054] At the beginning of power-on, the battery management units 111, 121, 131 and 141 send initial messages to the control unit 21, and the control unit 21 includes a counter (not shown in the figure), which is used to count the number of IDs sending initial messages, and control Unit 21 is used to judge whether the number of IDs obtained by statistics is the same as the number of battery packs. If they are the same, it means that the initial code of the battery pack is normal and can communicate normally, and there is no need to re-encode the battery pack; if it is different, it means the same If there is a battery pack with the same code in the battery pack and the communication cannot be normal, the battery pack needs to be coded again. In this case, the control unit 21 sends a code start command to the battery management uni...

Embodiment 3

[0060] The automatic coding method of the sub-box type quick-change battery of the present embodiment is realized by the automatic coding system of the sub-box type quick-change battery of embodiment 1, figure 2 shows the flowchart of this embodiment, refer to figure 2 , this embodiment includes the following steps:

[0061] S101. The control unit sends an encoding start instruction to the battery management unit of each battery pack;

[0062] S102. The battery management unit sends the first message to the encoding unit according to the encoding start instruction, and the ID of the first message is generated according to the battery code;

[0063] S103. The coding unit acquires the battery code according to the first message;

[0064] S104. The coding unit assigns different communication codes to the battery pack according to the battery code;

[0065] S105. The coding unit generates a second message based on the battery code and the communication code and sends it to th...

Abstract

The invention discloses an automatic coding system and method for a box-splitting-type quick-change battery. The automatic coding system for the box-splitting-type quick-change battery comprises the box-splitting-type quick-change battery and a coding management module, wherein the box-splitting-type quick-change battery comprises a plurality of battery packs with battery management units and an unique battery code; the coding management module comprises a control unit and a coding unit preset with a plurality of different communication codes; the control unit sends a coding start instructionto the battery management units; the battery management units send a first message to the coding unit according to a message ID generated by the battery codes; the coding unit obtains the battery codeaccording to the first message, allocates different communication codes to the battery packs according to the battery code, generates a second message with the battery code and the communication codes as contents and sends the second message to the battery management units, and the battery management units save the corresponding communication code in the second message and sets the communicationcode as the ID of the sent message after the automatic coding is completed, so that the efficiency of quick battery change is improved.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an automatic coding system and method for box-type quick-change batteries. Background technique [0002] In the current battery quick-change system, the processing method for the box-type quick-change batteries is usually to store the box-type quick-change batteries in different areas in the swap station according to the battery numbers, and when the vehicle enters the swap station for battery replacement When using a battery, you first need to select a group of batteries with different numbers, and then complete the battery replacement operation through the battery replacement system. However, the current processing method easily causes multiple batteries of the same number to be installed on the vehicle, which in turn causes the vehicle to fail to operate normally and affects the efficiency of quick battery replacement. In addition, this processing method requires the swap station to ...
