Identification data embodiment and recognition methods between electric appliance, electrical equipment.Battery pack is numbered with unique battery code name,
Charger and electrical equipment can identify that unique battery code name, the existing code name are sequence number or identifier or other shapes
Formula.
Especially as shown in figure 8, between existing battery pack and charger, electrical equipment communication the problem is that, it is existing
The identity of one unique identity code mark battery pack of some, it may be assumed that 01,02,03,04,05 in figure, wherein 01,02,
03,04 code name is 1P；05 code name is 2P, and charger can identify that unique code formulates charging scheme, and machine can identify
The unique code formulates discharge scheme, when there is trendy battery pack, when being added such as battery pack that code name is 3P, it is corresponding this with 1P and
2P different battery parameter information, machine and charger can not identify, so being directed to the situation, existing method is used, after being
The mode of a trough is arranged in the new battery pack of phase exploitation, and there is corresponding code in trough, needs after developing new battery pack,
The corresponding battery parameter information of new battery pack is re-write in the trough, can just make charger and the machine recognition planning model
Interior battery pack is enclosed, writing process is cumbersome.For the battery pack not in planned range, it is not provided with the new electricity of trough write-in
The parameter information of Chi Bao, therefore electrical equipment and charger can not identify, can not be compatible with, and be restricted the expansion of product line.
As shown in Fig. 3, Fig. 7 and Figure 10, display is the identification between battery pack and charger, electrical equipment of the invention
Method and code data content.Battery pack is stored in memory module with battery information constant, when later period battery pack newly developed
