Using Arcadyan KVD21 Internet gateway on 12 volt DC battery power

With a separate 12 volt DC battery the available voltage would typically be roughly 12-12.6 volts (and up to 13.5 for LeFePO4 types). Therefore in order to operate the Arcadyan KVD21 (which requires 15 volts DC @ 3 amps) with a 12 volt battery, or in a vehicle, a “step-up” design is needed. These are less common.

6 Frequently Asked Questions about “12v lead-acid battery modified mobile power supply”

Can a modified ATX PSU charge a 12V lead-acid battery?

In order to charge a 12V lead-acid battery the modified ATX PSU needs to provide an output voltage of at least 13.8 V. In this work we investigated two ways to achieve this. Prior to modifying the PSU the achievable variation in the +12V rail voltage was determined by replacing resistor R6 (Fig. 5) with a variable resistor Rvar = 3 k.

How to charge a 12V lead-acid battery?

Therefore, to charge a 12V lead-acid battery using the modification suggested above, a resistor is connected in series with the lead-acid battery to limit the charge current to 2A. The charging waveform of a 12V lead-acid battery is shown in Fig 8. The battery was initially discharged to a voltage of 11.4 V.

Can a 12V battery charger repurpose a standard ATX power supply?

ICT equipment is usually replaced at regular intervals, usually before the equipment has failed, opening up the opportunity of providing a second-life through repurposing. In this paper we investigate the technical feasibility of repurposing the standard ATX power supply found in many desktop computers into a 12V battery charger.

Can waste computer power supplies be repurposed into 12V battery chargers?

This paper will demonstrate the technical feasibility of repurposing waste computer power supplies into 12V lead-acid battery chargers suitable for deployment in developing nations where access to battery charging facilities is sometimes limited but 12V batteries are more readily available.

Can ATX power supply be used as a battery charger?

In this paper we investigate the technical feasibility of repurposing the standard ATX power supply found in many desktop computers into a 12V battery charger. We provide an overview of the ATX power supply before describing how the power supply may be modified into a battery charger alongside experimental results.

Can an ATX PSU be used as a 12V battery charger?

This paper has proven the technical feasibility of repurposing an ATX PSU into a 12V lead-acid battery charger. The methodology has been practically demonstrated on a 300W ATX PSU kindly removed from the WEEE stream and donated to us by Aspire-Sheffield.
