AI Customer ServiceA situation could arise where a battery string is subjected to a charging condition or reverse current. This condition is avoided by the use of diodes. The function of the diode in a parallel
AI Customer ServiceBattery pack circuits can experience current overload, short circuit conditions or voltage transients (ESD,etc.) and require multilayer varistors and diode arrays to meet regulatory standards or to
AI Customer ServiceI have this circuit and I do not understand the purpose of the diode connected to the ground. This is a Bluetooth device (works at 3.3v) that has a 4x 18650 battery pack and a

AI Customer ServiceCircuitry in a battery pack, such as a gas gauge, needs to measure the battery-cell stack voltage at all times. This drives the decision to place the Li-ion protector FETs between the ground
AI Customer ServiceSo the battery pack has two charging inputs, one a proprietary plug with a diode in-line which is obviously for reverse polarity protection if that input is used to charge. In these, the diode
AI Customer ServiceIf the diode shorts you will drain your battery when the engine is off. If the diode goes open you will only lose some output and it won''t be necessary to do anything. If only one

AI Customer ServiceThe simplest means of preventing a battery from being charged from an external power source is to incorporate a blocking diode in the battery pack, as shown in Figure 1. The diode chosen
AI Customer ServiceI 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.
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?
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.
This diode is part of the ESD protection structure in the device. Atypical device will be protected to 1.5 to 2 kV by this internal structure. Typical end-equipment specifications will have an ESD requirement of 15 kV, requiring additional ESD protection components.
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.
Virtually all ICs will have an internal substrate diode from communication lines to the VSS ground connection. This diode is part of the ESD protection structure in the device. Atypical device will be protected to 1.5 to 2 kV by this internal structure.
