摘要: A method for controlling an electrochromic device comprises obtaining (210) of a target colouring level and measure initial level. open circuit voltage between electrodes the is obtained (220). applied calibration ramped (230). charging current measured (232) during ramping voltage. The interrupted (236), intermittently temporarily (238). stopped (240) when condition met. constant main charging/discharging (250). selected in dependence stopped. Application removed (270) reached. An capable performing such procedure disclosed.
