[0004] However, in the prior art, under the condition that multiple sets of PACKs are used in parallel, the method of using the output of the PACK power end to wake up the rest of the PACKs can only wake up the load end without detection
When the PCS at the load end needs to detect the PACK state before it can output normally, it cannot meet the application scenario. In addition, if the load output end is faulty, it may cause the device to burn out or damage the device if the power line wakes up, and the physical button of a single PACK Wake-up method, cumbersome operation, not convenient enough

Embodiment Construction
[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments.
[0048] see figure 1 , figure 1 It is a schematic diagram of the system architecture of the parallel battery pack wake-up control system 100 according to an embodiment of the present application. The wake-up control system 100 in the embodiment of the present application may include parallel battery packs.
[0049]The parallel battery pack in the embodiment of the present application may include a plurality of battery packs connected in parallel ( figure 1 Only three battery packs 10a, 10b, 10c are taken as an example for description, and there may be more or less than three). That is, the plurality of battery packs are connected in parall...

The present application provides a wake-up control system for parallel battery packs, comprising a first battery pack and a second battery pack connected in parallel, the first battery pack comprising a first control unit, the second battery pack comprising a second control unit, The first battery pack is configured to receive a first trigger signal to wake up the first control unit of the first battery pack, and the first control unit of the first battery pack is configured to output a first drive signal after being woken up , the second battery pack is used to receive the second drive signal sent by the first battery pack, and process the second drive signal and transmit it to the second control unit of the second battery pack to wake up the first battery pack The second control unit of the two battery packs, wherein the second driving signal is output after processing the first driving signal by the first battery pack. The present application also provides a wake-up control method for parallel battery packs. The parallel battery pack wake-up control system and method provided by the embodiments of the present application meet functional safety requirements, are convenient to operate, and improve user experience.
Description
technical field [0001] The present application relates to the field of battery technology, and in particular, to a wake-up control system and method for parallel battery packs. Background technique [0002] In order to cope with the increasing demand of users for the power and endurance of energy storage batteries, if the single battery pack solution is still adopted, the energy density and cell capacity of the battery pack cells will inevitably increase, thereby increasing the volume and weight of the battery pack, and increasing the battery pack. R&D, manufacturing, transportation and installation costs of the group. With the battery pack parallel scheme, from the perspective of research and development, only one set of low-capacity scheme needs to be designed, which reduces the developer's research and development and safety certification costs. [0003] At present, the wake-up method of the existing energy storage system is to output the power end of the multi-level par...
