2results about How to "Guaranteed current efficiency" patented technology

The sampling method includes: identifying (S11) whether a waveform of a current period falls at a boundary of a sector region where a phase current of at least one phase is unable to be collected; determining (S12) a first duty cycle and a transforming channel mode for a channel of the at least one phase; storing (S13) the first duty cycle and the transforming channel mode in a buffer, and enabling a direct memory access (DMA) mode to the buffer at the same time; transforming (S14) a part of the waveform of the current period by configuring the channel of the at least one phase with the first duty cycle and the transforming channel mode; and acquiring (S15) the phase current of the at least one phase based on a transformed waveform of the current period.

A die coater capable of simultaneously coating a current collector with two different liquids in multiple layers includes a first body with a first manifold for an electrode slurry, a second body with a second manifold coupled to the first body to form a first slit through which the electrode slurry in the first manifold is discharged, and a third body coupled to the second body to form a second slit through which the electrode slurry in the second manifold is discharged. The first slit is formed by a first and third shim that are interposed between coupling surfaces of the first and second body, and the second slit is formed by a second and fourth shim that are interposed between coupling surfaces of the second and third body, and at least any one of the third shim and the fourth shim forms an insulating liquid slit.
