My understanding is that refresh rate is irrelevant. E-paper is not a digital screen. It is digital paper. You have black/white, bits turned on/off. The reason it is so efficient is that it consumes no power to display, only to turn the page. That is why the power is rated in number of pages, not in hours.
One note. I've been watching this technology. This is not insignificant. The power of e-paper is phenomenal as the capabilities to display pages the size of newspapers and can be changed on based on user preferences. I'm sure color will not be far down the road.
