Hello,
we are currently pondering whether to use a Li-Ion battery with BMS for our
mobile respiratory ventilator.
Our load for the battery would vary between 0,5A and 4A with a frequency of
max 1Hz and an ON/OFF ratio of 1:1 through 1:5.
Looking at the bq20z45 we assume the coulomb counter to have a measurement
update rate of 4Hz. Is this assumption correct?
The bq20z45 has got something called " Pulsed Load Compensation". But the
technical manual does not explain the algorithm which presumably makes
use of a variable called "Delta Voltage".
What accuracy can one expect for the calculation of the remaining capacity
with above mentioned pulsed loads and the "Pulsed Load Compensation"?
Is the algorithm in question designed in a manner to make sure the
remaining capacity will never display more energy than actually is in
the battery?
Kind regards, looking forward to your answers!
