Ion:There are two kinds of ions. The one is the cation which is formed when an atom leaves electrons from its last shell. The second is the anion which is formed when an atom accepts electrons. The formation of ions takes place so that the atom becomes stable....
The smartphone decides how much power it requires to charge the battery at any instant, then sends this information as a digital signal to the wall charger. On receiving this signal, the wall charger regulates the voltage and current. When the battery is at zero level, the smartphone operates...
It does this by using a "regenerative braking" system. That is, instead of just using the brakes to stop the car, the electric motor that drives the hybrid can also slow the car. In this mode, the electric motor acts as a generator and charges the batteries while the car is slowing ...
What is a battery’s state of charge (SoC)? What is a battery's cyclic life? Lithium-ion vs. lead-acid batteries Battery temperature: Why does it matter? Which battery is the right option for you? Compare storage options on EnergySage We’ve all experienced that dread: Watching...
As you close in on O% you’re running on empty — then you’re out of gas. Depth of Discharge (DoD) measures a battery’s state of charge in reverse. The formula is DoD = 1 – SoC. In other words, if you only have 10% of the battery’s total storage capacity left, the DoD...
The battery is the heart of an electric vehicle (EV), as it stores electrical energy in chemical form. It typically consists of lithium-ion cells connected in series and parallel configurations. Modern EV batteries are designed for high energy density, long life, and fast charging. Each battery...
What is the Range of EVs? The range of an electric vehicle is nothing but the distance a vehicle can travel on one full charge. It is a crucial factor for buyers to consider while buying a new EV. This is an important factor to consider as EV is a new technology and the infrastructur...
What is the Nintendo Switch battery life like? Nintendo claims that the standard LCD version of the Switch gets anywhere between 2.5 to 6.5 hours of playtime on a single battery charge. The OLED model can allegedly last 4.5 to 9 hours. The Switch Lite falls in between, with 3 to 7 hour...
