Charging Process of the Board Battery I, Out, Output Side of the Charging Converter:
A new, complete main charging cycle will be executed:
•
After a standstill of the generator or removal of the control signal D+ or Kl.15.
•
If the voltage of the starter battery has dropped below the adjusted switching off threshold for more than 30
seconds.
•
If the battery voltage drops below the reset voltage of approx. 13.2 V (depending on type) for 30 seconds due to high
load beyond the maximum charging current.
•
If the charging converter had been switched-off by means of the remote control and on subsequent restart.
1.
Charging aid for totally discharged (lead) batteries. From 0 V, they will be subject to gentle preliminary charging for
recovery with a small current rate up to approx. 9 V.
2.
Main charging
with maximum charging current (
phase I
) in the mean voltage range up to close to the phase U1
for
short charging times
, LED
"Main Charging"
is lighting, and approx. 85 % - 95 % of the capacity will be charged. The
duration of phase I depends on the battery conditions, the load by the consumers and the charging state. The
charging converter records the charging process. For reasons of safety, the phase I will be terminated by the safety
timer after 15 hours, at the latest (cell defects of the battery etc.).
3.
In case of high battery voltage rates, the charging current will be slightly reduced for battery protection (orientation
phase). After that, automatic switching to the following phase U1.
4.
During the
phase U1
(
full charging
, cell equalization charging, LED "
Main Charging
" is lighting), the battery voltage
will be kept constant on a high level. The green LED
"Battery Full"
is flashing
(at first, short flashing, with rising
charge increasingly longer flashing), and gentle charging of the additional high battery capacity. The charging
converter controls the charging time as well as the charging current. From these values and from the course of
charging being recorded during the phase I, the charging converter determines the
100 % full charge point
of the
battery for automatic switching to U2. In case of only slightly discharged batteries, the duration of phase U1 will be
kept short for relief of the battery. In case of major discharge, the phase U1 must be extended until the battery had
been fully charged. During this process, any influence by consumer loads is avoided reliably. The LED
"Main
Charging"
turns off at the end of the phase U1.
5.
Phase U2 (Full trickle charge, LED "Battery Full" is lighting permanently):
The charging converter has now switched
to the lower voltage for trickle charge maintaining and buffering 100 % charge of the battery.
During the normal operation (driving), the charging converter remains in the 24 hour phase U2. With some charging
characteristic lines, the following switching to the phase U3 were effected again with reduced charging voltage
(storage/trickle charge).
Note:
During the
phases
U1, U2
(U3) (Battery Full) almost the total
charger current is available for
additional
supply of consumers
without any discharge of the battery.
Any consumed energy will be recharged immediately.
