Embodiment Construction

[0027] The identification allocation method provided by the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 and figure 2 As shown, according to an embodiment of the present invention, the present invention provides a method for assigning labels in a distributed battery management system. The distributed battery management system includes a main controller and a plurality of lower computers, and the main controller and a plurality of lower computers A lower electromechanical connection in the computer, the lower computer is electrically connected in series with other lower computers in sequence, and the method includes:

[0029] 1) The main controller switches the lower computer electrically connected to it from the waiting state to the active state;

[0030] 2) The lower computer in the activated state sends a request for assigning an identifier to the main controller;

[0031] 3) The main controlle...

Abstract

The invention discloses a distributed battery management system and an identifier assignment method thereof. The distributed battery management system comprises a master controller and a plurality of slave controllers, wherein the master controller is electrically connected with one of the plurality of slave controllers, and the slave controller is electrically connected in series with other slave controllers in turn. The method comprises the following steps of: 1) switching the slave controller which is electrically connected with the master controller from a wait state to an enabled state by using the master controller; 2) sending a request for identifier assignment to the master controller by using the slave controller which is in the enabled state; 3) receiving the request by using the master controller; 4) responding to the request to generate an identifier by using the master controller; 5) assigning the identifier to the slave controller which sends the request by using the master controller; 6) allowing the slave controller which is assigned with the identifier to enter an assignment completion state and switch the next slave controller which is electrically connected in series with the slave controller from the wait state to the enabled state; and 7) repeating the step 2) to the step 6). By the distributed battery management system and the identifier assignment methodthereof, identifiers can be assigned to the plurality of slave controllers simply, effectively and reliably.

Description

technical field [0001] The present invention relates to a distributed battery management system, and more particularly, to a distributed battery management system for an electric vehicle or a hybrid electric vehicle. Background technique [0002] With the increase of electric equipment, there are more and more applications of battery packs that can supply power. During the use of battery packs, the battery management system must monitor the voltage, current, and temperature of the battery cells in real time, so that the battery management system Accurately predict battery performance. [0003] Battery management systems are generally divided into centralized battery management systems and distributed battery management systems. The distributed battery management system generally includes a main controller (battery management controller) and a lower computer (data acquisition module). With the increase of the number, the interface resources of the main controller are easy t...
