2. ‘Must know’ features and facts
2.1 Blue Smart version only
Set-up, monitor and update the charger (add new features when
they become available) using Apple and Android smartphones,
tablets or other devices.
2.2 Ultra high efficiency ‘green’ battery charger
With up to 95% efficiency, these chargers generate up to four
times less heat when compared to the industry standard.
And once the battery is fully charged, power consumption
reduces to 0,5 Watt, some five to ten times better than the
industry standard.
2.3 Durable, safe and silent
- Low thermal stress on the electronic components.
- Protection against overheating: the output current will
reduce as temperature increases up to 60°C, but the
charger will not fail.
- When the NIGHT or LOW mode are activated, the
maximum output current is reduced to 50% of nominal, and
the fan will be off.
2.4 Temperature compensated charging
The optimal charge voltage of a lead-acid battery varies inversely
with temperature. The Blue Power IP22 Charger measures
ambient temperature during the test phase and compensates for
temperature during the charge process. The temperature is
measured again when the charger is in low current mode during
float or storage. Special settings for a cold or hot environment are
therefore not needed.
2.5 Adaptive Battery Management
Lead-acid batteries should be charged in three stages, which are
[1] bulk or constant-current charge,
[2] absorption or topping
charge and [3] float charge.
Several hours of absorption charge are needed to fully charge the
battery and prevent early failure to sulfation¹.
The relatively high voltage during absorption does however
accelerate aging due to grid corrosion on the positive plates.
