6 FAQs about [Battery pack parallel connection with diode function]

What happens if two batteries are connected in parallel?

Nothing is "fine" with connecting two batteries in parallel if they aren't the same (bought the same day also). With diodes you get additional loss, because there is a voltage drop across diode 0.7V. Or 0.4 to 0.5 if you use Schottky diodes.

How does a diode 'or' switch work?

From your edit, you now have the Diode "OR" logic diode switch for the Load so that the higher battery source voltage drives the load using Common Cathode (-). The Charger charges the battery voltage with more current on the one with the lower voltage until equal using Diode "AND" logic using "Common Anode"

How does a battery diode work?

The diodes stop the batteries from shorting to each other, but they also deliver 36 V to your '12 V' output. If your low voltage drain is very, very small, say less than 1% of the drain on the whole pack, then you could maybe supply it from one battery, and rely on the charger to rebalance the cells when you recharge.

Do you use diodes for 12V batteries?

I use 3 12V batteries wired in series for 36V, and use diodes to wire them in parallel for the 12V. The diodes stopping the batteries from shorting. I know diodes have a considerable voltage drop, and for the EV application I would use ideal diodes. By using the diodes, all batteries should drain equally, avoiding the battery pack unbalancing.

Why do EV batteries need diodes?

The diodes stopping the batteries from shorting. I know diodes have a considerable voltage drop, and for the EV application I would use ideal diodes. By using the diodes, all batteries should drain equally, avoiding the battery pack unbalancing. In the EV, the 12V batteries would be separate modules with their own monitoring. Is this a crazy idea?

Is it possible to put a capacitor in parallel without a diode?

Yes , but this is old school, with better quality matching people will put in parallel without diodes to avoid the losses and then monitor current using ground strap mV drop to check for bad battery not sharing current,. If it were not for diode D2 capacitor C1 would be discharged by R1 (and D1) in the absence of battery Voltage.
