Docking And Charging; Battery - Husqvarna Automower Solar Hybrid Technical Manual

Depending on the placement of the charging station,
the Automower may be forced to leave the F-field to
reach the charging station. The mower then follows
the boundary wire out of the F-field. First it runs
10 metres (30 ft) from the F-field in one direction
before it turns and follows the boundary wire
20 metres (60 ft) from the F-field in the other
direction. Should the Automower then not reach the
F-field, it turns for a third time and follows the
boundary wire in the first direction until it reaches the
charging station.

1.13 Docking and charging

This section only applies to 220 AC, 230 ACX and
Solar Hybrid.
When the battery level becomes too low, the
Automower switches off the blade motor and starts to
search for the charging station. When the mower
receives the N-signal and enters the charging station,
this is called docking.
When the charging strips on the Automower make
contact with the contact strips on the charging station,
the mower stops and charging begins. The message
Charging is shown on the display.
A fault message is displayed when docking fails or
when charging does not work correctly, see table 11.

1.14 Battery

The available capacity drops with a rising ambient air
temperature. The mower adapts itself to this and
returns to the charging station earlier (Does not apply
to 210 C).
Battery charging is normally monitored by the control
box via a temperature sensor in the battery. The
temperature of the battery rises during the entire
charging process.The temperature of the battery rises
during the entire charging process. On 220 AC, 230
ACX and Solar Hybrid, when the battery is fully
charged, the temperature rises faster and charging is
stopped. Charging is also stopped should the battery
temperature rise above 53 ºC (127 ºF). On 210 C
charging is stopped at 48 ºC (118 ºF) or when the
mower has been charged for 15 hours. The mower is
considered to be fully charged when charging is
stopped.
Normal charging current for 210 C is 2 x 0.3 A, for 220
AC 1.75 A and for 230 ACX 2 x 2.0 A. Supply current to
the mower is 0.6 A for 210 C and 4 A for 230 ACX.
If the control box is blocked, for example, by
unintentionally interrupting programming, battery charging
is not monitored. It is then important that you charge the
Automower with caution, that is to say, for no more than
10 minutes. A blocked control box is characterised by no
text being shown on the display/no LEDs are lit and the
keypad does not work despite the battery being charged.
