DENSO developed by "Prius rechargeable hybrid cars" used battery monitoring unit
In order to reduce costs, Denso has not with mini-computers to control each battery unit of charge status, instead of using a simple circuit plus a comparer for the control.

Newly developed battery monitoring unit to take advantage of comparators detect each battery unit of voltage and their average value. In addition, according to various battery cell voltage, the comparator will output different voltage. That is, when a battery cell voltage is lower than the average of all battery cell, it will be repeated in some power, and vice versa.
DENSO alleges that the Prius rechargeable hybrid vehicle equipped with a 3 cell battery monitor, a bottom floor monitors 96 total battery unit, monitors 288 units of lithium ion rechargeable battery.
