Page 12: Operation
Blue Smart IP65 Charger 4. Operation 4.1. Charge algorithm The Blue Smart IP65 Charger range are intelligent multi-stage battery chargers, specifically engineered to optimise each recharge cycle and charge maintenance over extended periods. The multi-stage charge algorithm includes the individual charge stages described below: Test Before the charge cycle commences the battery is tested to determine if it will accept charge, even if the battery is fully discharged (close to 0V open circuit voltage) it may successfully accept charge. - Page 13 Blue Smart IP65 Charger Storage The battery voltage is maintained at the configured storage voltage, which is slightly reduced compared to the float voltage to minimise gassing and extend battery life whilst the battery is unused and on continuous charge. Repeated absorption To refresh the battery and prevent slow self-discharge while in storage stage over an extended period, a 1 hour absorption charge will automatically occur every 7 days (or as configured).
-
Page 14: Charge Modes
Blue Smart IP65 Charger 4.2. Charge modes There are 3 integrated charge modes (Normal, High and Li-Ion), as well as an optional Recondition stage that can be included (except for Li-ion mode). The integrated charge modes combined with adaptive charge logic are well suited for most common battery types; such as flooded lead-acid, AGM, Gel and LiFePO4. -
Page 15: Low Current Mode
Blue Smart IP65 Charger 4.2.3. Low current mode When low current mode is enabled the maximum charge current is limited to a significantly reduced level (varies per model); refer to the 'Technical specifications' section for more information. Low current mode is recommended when charging lower capacity batteries with a high current charger; charging at an excessive charge current can cause premature battery degradation and overheating. -
Page 16: Temperature Compensation
Blue Smart IP65 Charger 4.3. Temperature compensation The Blue Smart IP65 Charger range feature temperature compensation, which will automatically optimise the nominal/ configured charge voltage based on ambient temperature (except for Li-ion mode or if manually disabled). The optimal charge voltage of a lead-acid battery varies inversely with battery temperature; automatic temperature-based charge voltage compensation avoids the need for special charge voltage settings in hot or cold environments. -
Page 17: Commencing A New Charge Cycle
Blue Smart IP65 Charger 4.4. Commencing a new charge cycle A new charge cycle will commence when: The configured Re-bulk condition is satisfied (typically due to a large load): Re-bulk current is disabled (default configuration): The current output must be maintained at the maximum current output for four seconds. -
Page 18: Estimating Charge Time
Blue Smart IP65 Charger 4.5. Estimating charge time The time required to recharge a battery to 100% SOC (state of charge) is dependant on the battery capacity, the depth of discharge, the charge current and the battery type/chemistry, which has a significant effect on the charge characteristics. 4.5.1. -
