P22Victron Energy Blue Smart IP22 Smart Car Battery Charger 12V 30A, Trickle Charger Float Charger and Desulfator

Bluetooth Smart 
The wireless solution to monitor voltage and current, to change settings and to update the charger when new 
features become available. 
 
High efficiency 
With up to 94 % 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.
Adaptive 6-stage charge algorithm: test - bulk – absorption - recondition – float – storage 
The Blue Smart Charger features a microprocessor controlled ‘adaptive’ battery management. The adaptive 
feature will automatically optimize the charging process relative to the way the battery is being used.
Fully programmable charge algorithm 
Absorption, Float and Storage voltages as well as the Recondition setting and the temperature compensation 
value can be programmed with the Bluetooth app.
After enabling the Expert mode, the app allows changing practically all parameters and time limits used by the 
charge algorithm.
Storage Mode: less maintenance and aging when the battery is not in use 
The storage mode kicks in whenever the battery has not been subjected to discharge for 24 hours. In the storage 
mode float voltage is reduced to 2,2 V/cell (13,2 V for a 12 V battery) to minimize gassing and corrosion of the 
positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize’ the battery. This feature 
prevents stratification of the electrolyte and sulfation, which are major causes of early battery failure.
Also charges Li-ion batteries 
Li-ion batteries are charged with a simple bulk – absorption – float algorithm.
Fully discharged battery recovery function 
Will initiate charging even if the battery has been discharged to zero volts.
Will reconnect to a fully discharged Li-ion battery with internal disconnect function.
NIGHT and LOW setting 
When in NIGHT or LOW mode, the output current is reduced to max. 50 % of the nominal output and the charger 
will be totally noiseless. The NIGHT mode automatically ends after 8 hours. The LOW mode can be ended 
manually. 
Protected against overheating 
Output current will reduce as temperature increases up to 50 °C, but the Blue Smart Charger will not fail.
Eleven LEDs for status indication 
Charge algorithm: TEST / BULK / ABSORPTION / RECONDITION / FLOAT / STORAGE / READY.
MODE button to set: NORMAL (14,4 V) / HIGH (14,7 V) / RECONDITION / LI-ION.
Forty cycle history log 
The history screen contains historical usage data over the charger’s lifetime and detailed statistics for the last 40 
charge cycles.
VE.Smart Networking 
The VE.Smart Network is a wireless device to device (D2D) communication network between Victron products, 
using Bluetooth Smart.
Optional battery voltage and temperature compensation, and current sensing 
The VE.Smart Network opens the possibility to optimize the charge process: a Smart Battery Sense, Smart 
Battery Monitor or a SmartShunt can be used to communicate battery voltage and temperature to one or more 
battery chargers. A Smart Battery Monitor or SmartShunt will also communicate battery current.
Synchronized parallel charging 
Synchronize up to ten battery chargersin a VE.Smart network to make them charge a battery as if they were one 
large charger. The chargers will synchronize the charge algorithm between them. They will simultaneously switch 
from one charge state to another, for example from bulk to absorption.
Synchronized parallel charging has several interesting advantages:
- Redundancy: if one charger stops for whatever reason, the other chargers will continue to operate.
- Flexibility: simply add a charger to the network if more current is needed.
- Cost: several low power chargers will in general cost less than one high power charger.
- Installation: several low power chargers may be easier to fit in a confined space.
