In lithium-ion battery packs, "undercharge" generally refers to insufficient battery capacity, meaning the remaining charge of the battery pack is lower than the minimum required for normal operation.
This will ensure that the actual usable energy output matches your calculated energy requirement. As a rule of thumb, you may need to oversize the battery capacity by around 10-20% to account for these losses. For example, let's say you have a requirement of 15 kilo-watt hours, the additional capacity will be determined as follows:
Even in the late 1800s and early 1900s, most automobiles did not use batteries because they did not need them. Early gasoline engines used either a hot-tube ignition or the magneto to fire the spark plugs. One of the first electrical devices that required a battery was the horn, which was originally called the Klaxon from the Greek word klaxo.
Energy is released as DC and it moves in two directions. When energy is removed, the battery is discharging. When energy is replaced by the alternator or a battery charger, the battery is being charged. Taking too much energy out and too frequently is considered “deep cycling,” and this is where you can damage and reduce your batteries' lives.
To put things into perspective, think of your batteries as a bank account. If you don't replace what you withdraw, you will soon be out of money. The same thing happens to your batteries. If you keep taking out current without recharging properly, you will end up with damaged or dead batteries.
Teach them to keep in mind that a 12-volt battery is fully charged at 12.66 volts (six cells at 2.1 volts per cell), and if the voltage dips below this, discharge is occurring and that is what we don't want. Keeping this explanation simple, it is important for drivers or operators to get a good understanding of the system.
