Batteries are mobile power sources

What is a battery used for?

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.

How do batteries store energy?

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.

Can batteries power electric cars?

Batteries not only power electric cars, but can supply energy to buildings and stabilize power grids, through bidirectional charging. Electric cars boast increasingly powerful batteries that are charged from the energy grid or rooftop solar systems.

Do batteries make our energy supply greener?

Batteries are a non-renewable form of energy but when rechargeable batteries store energy from renewable energy sources they can help reduce our use of fossil fuels and cut down carbon dioxide and greenhouse gas production. Find out why batteries may have a key role to play in making our energy supply greener. What is a battery?

What can a charged battery power?

A charged battery could not only power the electric motor, electronics, lights and heating but external devices such as a fridge when camping, a drill on a building site or even another EV. These additional functions are called V2D (vehicle-to-device), and V2L (vehicle-to-load).

What are batteries & how do they work?

Batteries are stores of chemical energy that can be converted to electrical energy and used as a power source.
