文摘
- •
Two circuit models useful in elucidating constant current (CC) versus constant voltage (CV) CDI energy consumption dynamics.
- •
CC mode consumes significantly less energy than CV mode for equal amounts of input charge and identical charging duration.
- •
CC mode has approximately same salt removal as CV and avoids initial high-power resistive dissipation of CV mode.
