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.

How is a diode connected to a battery?

A diode can be connected to a battery in two ways, either forward or reversed- biased. First is reverse-bias, the anode of the diode to negative terminal of the battery and the cathode to the positive terminal of the battery.

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?

Do you use diodes for a BLDC motor?

For example, lets say I need 36V for a BLDC motor, and 12V for a Arduino. 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.

How to Power Raspberry Pi Pico with Batteries: Li-ion

In order to safely connect a battery or secondary power source to Pico, we can add a diode between the second power source and the VSYS pin. This will prevent one power source from back-feeding the other. Whichever power source has the higher voltage will send power to the Raspberry Pi Pico board. Power OR-ing of VBUS and VSYS pins in Raspberry Pi …

How to build a battery pack from pouch cells | ELECTRICBIKE

I''ve seen some battery pack builders use a paper-hole punch to make a hole in tabbed pouch cells, but these cells were ordered with thicker collector-tabs for the high current that Chris needed. The "punch" is made from a rod that has had a hole drilled into it sideways. This results in a shape that works well for punching holes through his alignment jig, shown on …
