A battery indicator (also known as a battery gauge) is a device which gives information about a battery. This will usually be a visual indication of the battery's state of charge . It is particularly important in the case of a battery electric vehicle .
The rated power of the original PS4 Pro is 310 W. [20] The decision not to upgrade was predicated primarily on cost. [20] A limited translucent-case version of the PS4 Pro was released in August 2018, which includes minor hardware updates. This new system, model number CUH-7100, besides offering a larger hard drive, used a quieter fan.
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.
Battery-powered equipment connected to mains electricity can be kept fully charged although switched on; for example, a mobile telephone can be ready to receive calls without depleting its battery charge. It enables devices to either turn on or off into a standby state automatically without human intervention (for example, a timer or Wake-on-LAN).
Low fuel/charge or re-fuel/re-charge – Appears when vehicle's fuel tank is nearing empty. Usually shaped like a gas dispenser, or a light next to "E" on the fuel gauge, and (most later cars) a buzzer. In an EV when the battery runs low, usually shaped with the EV charger symbol or the EV battery symbol and in most cases a buzzer or chime.
Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis.
Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
