Abstract: An electrochromic apparatus is disclosed. The electrochromic device can include a first bus bar electrically connected to a first transparent conductor, where the first bus bar comprises a first segment between a second segment and a third segment, where the first segment has a first thickness that is less than a second thickness of the second segment and less than a third thickness of the third segment. The electrochromic apparatus can further include a first voltage supply terminal that is offset from a center of the first bus bar.

Abstract: A method for controlling multiple electrochromic devices (ECDs) that have a variable tint profile. The method can include applying an initial test voltage profile to four or more bus bars of a first ECD, producing a first test tint profile in the first ECD in response to the initial test voltage profile, adjusting the initial test voltage profile to produce a first desired tint profile (DTP) in the first ECD, determining first modeling parameters based on the adjustments of the initial test voltage profile, modeling the first ECD based on the first modeling parameters, determining first compensation parameters via the first ECD model determining a first compensated voltage profile (CVP) by modifying the initial test voltage profile based on the first compensation parameters, and producing the first DTP in the first ECD in response to applying the first CVP to the first ECD.
