Batteries are used to store chemical energy. Placing a battery in a circuit allows this chemical energy to generate electricity which can power device like mobile phones, TV remotes and even cars. Generally, batteries only store small amounts of energy. More and more mobile devices like tablets, phones and laptops use rechargeable batteries.
Batteries can be used to power portable devices. They let devices use electricity without the need to be plugged into main electricity sources, such as wall sockets. Mobile phones, tablets, the TV remote and torches all use batteries. Some batteries are rechargeable so they can be used again and again.
A mobile device draws energy from the main power supply or one or more battery packs. The rechargeable battery needs to be small and light, but at the same time provide a lot of energy. Since these two requirements are contradictory, high energy density is at the top of the battery wish list. ………………………………………………………………………………………………….
One way of guesstimating the power usage from phone charging would be: 1 - Estimate how much charge your phone holds. Let's say 2000mAh 3.7V battery, so ~ 8Wh 2 - Lets say you fully charge your phone every day. 3 - Lets assume the charger circuitry in your phone has 80% efficiency and the USB PSU 60%.
Batteries store energy which means we can reduce waste of energy. This can help us to reduce the amount of non-renewable energy we use and therefore helps the environment. Many batteries are easy to remove and replace or recharge. Many batteries are small and portable, so they can provide electricity for mobile devices and vehicles.
Simply put, a power supply system for mobile devices consists of four logic blocks: source, distribution, consumption and charging. Each block has its own intelligence and contains hardware and software. For the success of a device, it is important that the battery lasts a long time, provides sufficient power and is light and small.
