This is a fatal problem. For this reason, a complete backflow prevention circuit with low current leakage is necessary. The simplest and most effective measure is configuring a complete backflow prevention circuit using the ideal diode IC.
A backward-installed battery reverse-biases the transistor, and no current can flow. This arrangement is better than the series diode, because the saturated pnp transistor offers a lower voltage drop than most diodes and thereby improves operating efficiency by lowering the power dissipation.
Since batteries are connected in series, when current comes out of one terminal and travels down wire, wouldn't it reach touch the terminal of another battery, not the same battery from which the current initially came out of? How are the battery in series organized?
A variety of circuits can provide this assurance. The simplest form of battery-reversal protection is a diode in series with the positive supply line (Figure 1a). The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery.
However when batteries are connected in series, how do currents flow from one side of terminal to another? Since batteries are connected in series, when current comes out of one terminal and travels down wire, wouldn't it reach touch the terminal of another battery, not the same battery from which the current initially came out of?
The current leakage of the ideal diode is about 0.1 μA even at high temperatures, however, for SBD, leakage current of 100 μA or more is flowing. This paper explained that using the ideal diode IC could easily configure the complete backflow prevention circuit.
