Using Diodes in a Lithium Ion Battery Bank

We have not worked with Diodes before and wanted opinions on a design idea that we have. We are installing (8) lithium ion batteries (12V 100AH each) in parallel in an RV. In order to reduce the risk of circumfluence, we want to use diodes to be sure that the power from the battery bank goes in only 1 direction (charging or discharging). We are thinking of using

Protect lithium battery in parallel

$begingroup$ Because the intrinsic diode is in parallel with the FET. If you have two batteries connected the two FETs are turned on and there is a balancing current path available. The FETs short out the intrinsic diodes. So you have to put diodes in series with the battery to control battery to battery current. $endgroup$ –

6 FAQs about [Diode series lithium battery pack]

Do you use diodes for 12V batteries?

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?

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.

What is a safety circuit in a Li-ion battery pack?

Fig. 1 is a block diagram of circuitry in a typical Li-ion battery pack. It shows an example of a safety protection circuit for the Li-ion cells and a gas gauge (capacity measuring device). The safety circuitry includes a Li-ion protector that controls back-to-back FET switches. These switches can be

What is the primary protection on a battery pack?

It contains both primary and secondary protections to ensure safe use of the battery pack. The primary protection protects the battery pack against all unusual situations, including: cell overvoltage, cell undervoltage, overtemperature, overcurrent in charge and discharge, and short-circuit discharge.

How do you use a diode in a communication line?

To implement the first method, a diode is placed in the communication line with a parallel capacitor and high-value pull-down resist-ance on the battery side of the diode. The diode is typically a Schottky diode to reduce the impact on the communication noise margin.
