Memory Function; Battery Detection - Bosch C30 Operating Instructions Manual

Bosch C30 charger I Operating instructions
Note:
For regeneration mode, make sure that all connections between the battery and the ve-
hicle electrical system are disconnected.
4.1 Pulse charging
This is an automatic charging function that cannot be selected manually.
If the battery voltage in modes 1 & 3 is between 7.5 V (± 0.5 V) and 10.5 V (± 0.5 V) at
the start of the charging process, the charger will automatically switch to pulse
charging to avoid damaging the battery and to ensure intelligent charging.
4.2 Trickle charging phase
The charger has an automatic trickle charging phase with max. 200 mA at full charge.
4.3 Maintenance phase
When the battery is fully charged, "100%" LED lights up. The charger will start the
maintenance phase to keep the battery capacity in full condition.
4.4

Memory function

If the charger is disconnected from the mains during the charging process, the device
saves the previously selected mode. When reconnected to the mains and with the same
battery type (6 V or 12 V), the device will automatically start in the last mode.
Caution: If the connected battery type is different from the last one used (e.g. if you
were in cold/AGM mode last time and you need to connect a normal lead-acid battery
this time), please reselect the mode manually to avoid overcharging or damage.
There is no memory function for mode 4 (regeneration mode).
4.5

Battery detection

Once the charger is connected to a 7.3 V - 10.5 V battery, the 6 V & 12 V LEDs will
flash. The charger will attempt to automatically detect the battery voltage (6 V or 12 V)
using an elaborate measurement process.
After 1-3 minutes, the charger will detect whether the battery is 6 V or 12 V and switch
to the appropriate mode.
4.6 Override mode
If the charger detects a connected battery as a 6 V battery and switches to 6 V mode,
but the user is very sure that the battery type is 12 V, the user can press and hold the
mode button for 5 seconds to switch the charger to any 12 V charging mode.
I
CAUTION
The 12 V mode can charge the battery from a voltage as low as 3.75 V. As a result, a 6
V battery could be overcharged and cause further hazards (increased gassing, explo-
sion, fire...) to humans and animals.
