Votronic StandBy-Charger 12 V

The VOTRONIC Automatic Chargers, which are equipped with the latest charging technology and designed for all commercially available lead batteries, ensure correct battery charging (see chapter Charging technology). The peripheral devices from VOTRONIC, which work in the background and provide automated charge control and battery monitoring, ensure that the batteries are treated correctly in daily operation.
In motorhomes, camper vans and even emergency vehicles, etc., the batteries must also supply energy when the vehicle is stationary. For this reason, several batteries are usually installed in these vehicles, which are used separately for driving and stationary operation.
A distinction is made between starter and supply battery(ies). As the name suggests, one battery is responsible for reliably starting the vehicle, while the other(s) supplies power to the electrical devices in the vehicle. To ensure that each battery circuit works reliably and that the vehicle's electrical concept functions properly, various devices are used to control charging while the vehicle is in motion.

StandBy-Charger

The VOTRONIC StandBy-Charger is used to automatically recharge and maintain the charge of the starter battery or the auxiliary battery if the mains charger, the solar charge controller or the generator only has one charge output. The device can be easily retrofitted by simply connecting it between the on-board and starter battery or on-board and auxiliary battery without having to change the existing wiring.

If, for example, the mains charger is in operation and charging the on-board battery, the second battery (starter battery or auxiliary battery) is also charged with a small portion of the charging current, depending on the state of charge. This charge retention works automatically and is recognisable by an increased voltage level of the second battery. The second battery cannot be overcharged as the charging voltage is reduced by at least 0.6V and the charging current is limited to 3A (24V version: 2A).

Notes:

• Make sure that both batteries have the same nominal battery voltage of 12 V / 12 V or 24 V / 24 V, as mixed operation of 12 V and 24 V is not possible.
• The StandBy-Charger is only suitable for use with lead batteries (acid / gel / AGM technology), not for the combination of LiFePO4 and lead (starter) batteries.
