Batteries
3. Each battery is individually monitored via a dedicated
processor-controlled “RTV” module. This also enables
defective batteries on a system to be identied. (Each
single battery can be changed instad of the mor expen-
sive exchange of whole battery line)
Traditional battery management systems have following
restriction: In the case of multiple batteries connected
in parallel, only one average voltage value is calculated
per block, which can cause individual defective batteries
amongst intact ones to be overlooked, thus diminishing
the capacity of the entire system.
On some battery management systems, voltage mea-
surements can be set to run over a dened long period
with a specied load, but these are of no help in this case.
4. The batteries of a system are charged to the same
level, which increases both the overall capacity and the
life expectancy of the system.
This elimiates another weak spot of conventional systems:
One defective battery can have such a negative impact
on the charging behaviour of intact batteries of the system
that these too are damaged. The defective battery thus
“infects” the others.
Fig. 3: All batteries attain the same charging level at the end of
the charging process, avoiding overcharging or deep discharging
of individual batteries and optimising overall capacity.
