IPC: G01R31/3842
Filed: 2020-01-28
Abstract: Provided is a system for determining a discharge power limit value and a charge power limit value of a battery cell. A microprocessor calculates an adjusted maximum allowable voltage drop value based on a maximum allowable voltage drop value and an estimated delta OCV value at N seconds after a first time point. The estimated delta OCV value is calculated based on a first discharge current level. The microprocessor calculates a second discharge current level indicating a magnitude of a constant current which must flow through the battery cell for N seconds, required for the voltage across both ends of the battery cell to drop by the adjusted maximum allowable voltage drop value. The microprocessor calculates the discharge power limit value based on the second discharge current level. The discharge power limit value indicates an amount of power which can be constantly consumed from the battery cell for N seconds without the voltage across both ends of the battery cell falling below a minimum allowable voltage of the battery cell.

The present invention solves all the problems such as the need to minimize the inflow of impurities and the loss of raw materials caused by frequent movement due to the repeated use for the objects to be shredded in stages, and a blade plate rotating body and a filter net matching thereto can be consecutively connected to, mounted on or detached from a motor rotating shaft so as to easily adjust according to the size of the crushed particles suitable for the purpose of use and removal of iron powder foreign substances from a final grinding result. Thus, the present invention is designed to expand and adjust the range of the object to be ground and ground particle output. Also, the multifunctional composite grinder is designed to easily remove foreign substances such as iron powder generated in all of the above work processes, and it is relatively easy to attach, dismantle, assemble, operate, and clean, thereby being very efficient, economical, and hygienic.
