Embodiment 1

[0046] Embodiment 1 of the present invention provides an intelligent battery connection system, such as Figure 2A As shown, it includes: a plurality of smart batteries 21, each smart battery 21 in the plurality of smart batteries 21 includes a battery controller 211 and a storage battery 212, and the battery controllers 211 of the plurality of smart batteries 21 are connected through a communication bus , the accumulators 212 of the plurality of smart batteries 21 are connected, wherein:

[0047] The battery controllers 211 of the plurality of smart batteries 21 determine a master battery controller through information interaction, and the battery controllers 211 of other smart batteries 21 other than the smart battery 21 to which the master battery controller belongs act as slave batteries controller;

[0048] The master battery controller controls the use of the accumulators 212 of the plurality of smart batteries 21 through information interaction with each slave battery ...

Embodiment 2

[0064] Embodiment 2 of the present invention provides a method for controlling the charging of the smart battery in the above-mentioned smart battery connection system, such as image 3 As shown, in the process of charging the accumulators of the plurality of smart batteries in the system, the following processing steps are included:

[0065] Step 301 , each smart battery in the system determines its own expected charging voltage when the reporting period arrives.

[0066] In this step, a smart battery can determine its own desired charging voltage in the following manner:

[0067] When the storage battery of the smart battery is currently connected to the battery bus, that is, in the charging state, the battery controller of the smart battery can determine its own expected charging voltage according to the current charging current, current temperature and current charging mode of the storage battery of the smart battery ;

[0068] Among them, the smart battery can detect th...

Embodiment 3

[0084] At present, in the smart battery connection system, new smart batteries can be connected in parallel online. The storage battery of the newly connected smart battery may be full or weak, and during the use of each smart battery in the system, It is also possible that the battery capacity of each smart battery is different, for example, the power of a certain smart battery is inconsistent with other smart batteries after self-test discharge. When the power of the battery is inconsistent, the open circuit voltage of the battery will be divided into high and low. Since the batteries with inconsistent power are currently connected to the battery bus, the full battery with high voltage after parallel connection may give a weak battery with low voltage. When the battery is charging, the charger is also charging the weak battery at this time, which may cause the charging current of the weak battery to be too large. Excessive charging current will affect the service time of the ...

Abstract

The invention discloses an intelligent battery connection system and a related control method, comprising: a plurality of intelligent batteries, and a main battery controller is determined through information interaction among the battery controllers of the plurality of intelligent batteries, except that the main battery controller belongs to The battery controllers of the smart batteries other than the smart battery are used as the slave battery controllers; the master battery controller controls the use of the accumulators of the multiple smart batteries through information interaction with the slave battery controllers. Using the scheme provided by the embodiment of the present invention, when the current main battery controller fails, another main battery can be selected from the battery controllers of other smart batteries except the smart battery to which the current main battery controller belongs. The controller, so as to continue to effectively control the use of each smart battery currently connected in the system.
