Battery Voltage Range
I wouldn't argue with that. Its really not the same issue I was referring to.
If in fact the regular cell operating range is 1.25V to 2.45V (1.96:1), Aquion batteries are
a very poor substitute plug in to many existing systems. As I recall most recently we were
designing office equipment to nominally run 39.5V to 54V, with a capability to 60V.
Those were disconnect points.
HOWEVER, the capability to use this range has existed for a while. DC - DC converters with
an input of 36V to 72V are common. Plug ins running on rectified AC will accept 120AC to
240 VAC or anything between. My 7.5KW grid tie inverters have an operating input range of
230V to 500V (with tolerance of 600V). This sort of equipment could run nicely over such
a battery range. So I see this as a matter of bringing the right equipment together; easy for
a brand new design, not so good for current apps.
What I liked most about Aquion, is the ability to tolerate severe DOD for some time without
damage. Lets recommend them to all those people who would wreck their first battery set.
