The invention provides electric quantity equalization function detection equipment comprising a controller, a plurality of current detectors and a battery simulator; the controller communicates with the battery simulator; the battery simulator has a plurality of interfaces respectively electrically connected with each current detector; each current detector is electrically connected with the battery management system; the controller is used for sending a battery simulation order to the battery simulator, wherein the battery simulation order comprises voltage output rules; the battery simulator is used for controlling the voltage value outputted by each interface of the battery simulator according to the voltage output rules of the received battery simulation order, thus controlling the battery simulator to be in an electric quantity disproportion state; the current detector is used for detecting current changes of the current detector when the battery simulator is in the electric quantity disproportion state, thus determining whether the battery management system has the electric quantity equalization function or not according to the current changes.
Description
technical field [0001] The invention relates to the field of new energy technologies, in particular to a battery balancing function testing device and method. Background technique [0002] At present, when testing the battery balancing function of the battery management system, the battery management system is connected to each single battery in the battery pack (battery PACK) through the data collection harness, that is, each data collection line is connected to a single battery, By manually charging and discharging a single battery in the battery pack connected to the battery management system, that is, manually setting the batteries in the battery pack in a battery unbalanced state (the voltage of each single battery is different). After the battery management system determines that the battery PACK is in a state of unbalanced batteries, it starts the balancing function, that is, charges the single cells in the battery pack that need to be balanced, discharges the remaini...
