Claim 1:
2. The electrochromic device of claim 1, further comprising first and second busbars respectively coupled to the first and second electrically conductive layers wherein (i) the first and second busbars are configured to receive a drive current IDRv to enable a current driven mode for switching the electrochromic device to a target optical state with respect to a minimum optical state and a maximum optical state thereof; (ii) the electrochromic device comprises a total charge capacity having a total charge QTOT; (iii) the target optical state is attainable by charging the electrochromic device to a target charge QTGT via the drive current hay, the target charge QTGT comprises a percentage of the total charge QTOT corresponding to a percentage of the target optical state relative to the maximum optical state; and (iv) the target optical state is predictably attainable for substantially all of a total optically switchable area of the electrochromic device, and within a target time TTGT, by adjustment of the drive current IDRV such that the product of the target time TTGT and the drive current IDRV substantially equals the target charge QTGT.
