NOQON charging boosters: NB & NBS series

They give freedom and save time: the NOQON charging boosters in the NB and NBS series. The letters NB in the series designations stand for "Battery Booster", the special devices for battery charging. This is where the NOQON charging boosters differ from conventional chargers: They allow a 12-volt battery to be charged by another 12-volt battery (battery-to-battery method, B2B for short). The charging process is controlled: the charging booster continuously checks the battery via the measuring lines to ensure that neither the supply battery is overcharged nor the starter battery discharged while driving.

NOQON NBS models - charge boosters with integrated solar charge controller

The S in the one NB series stands for the integrated solar charge controller, which, as an MPPT version, exceeds the efficiency of a conventional PWM charge controller. When the journey is interrupted or the vehicle arrives at its destination, solar charging starts automatically via the solar modules on the vehicle roof.

The NOQON NBS 30 achieves a solar charging output of up to 250 W/20 A, the NOQON NBS 60 even up to 430 W/30 A.

Charging process in three steps:

• Step 1: Maximum current up to the target value for constant voltage charging
• Step 2: Current decreases, constant voltage charging mode starts, charging time around 2 hours
• Step 3: Stop constant voltage charging at 12.6 volts battery voltage and start trickle charging

Installing the NOQON charge booster

The battery technology is selected via a DIP switch: Lithium or lead-acid/AGM/gel. The connection for the NOQON Charge Monitor CM 1 and the external NOQON Bluetooth dongle BTD1 is located on the battery booster. A monitor or smartphone informs the user about the current battery charge status, among other things.

Further connections, for example for a voltage measurement cable, temperature sensor or additional supply batteries, are also available.

Alternator as generator

The vehicle alternator works like an electric generator, which is driven by the combustion engine to charge the starter battery and consumer devices. When the starter battery is finally charged depends on its initial state of charge and the duration of the journey. If the battery is full, it can no longer hold any reserves. This is where the NOQON charge booster comes in handy. It takes over the energy that is

energy and stores it in an additional battery.

Loss-free charging

For optimum battery charging, the NOQON charge booster automatically adjusts the voltage measurement cables to the required values using an exact charging characteristic. In doing so, it compensates for line losses and voltage fluctuations from the generator that occur while driving - both for the battery and for the 12-volt consumer devices.
