It is a relatively new technology that has gained popularity due to its ability to store renewable energy sources such as solar and wind power. The concept of a heat battery is simple: it stores heat during times when excess energy is produced and releases it when there is a shortage of energy.
Heat batteries are units designed to store significant amounts of heat for later use, for example storing heat generated at night for use during the following day to provide space and water heating. The main factors affecting their performance are the amount of heat they can store and how well they can retain this heat.
Charging the heat battery refers to the process of adding thermal energy to the storage medium. The amount of energy supplied to the heat battery is determined by a charging function, which calculates the electric charge input to the system. The process of electric charging is an exercise of balancing.
One of the advantages of a heat battery is its ability to store energy for long periods of time without significant energy loss. This makes it an ideal solution for storing energy from renewable sources that are intermittent, such as solar and wind power. It also reduces the need for backup power sources that rely on fossil fuels.
For the embedded heating elements, Wang et al. embedded nickel foil inside the battery and utilized the heat generated by the nickel foil to heat the battery. Although this method can heat the battery from −20 °C to 0 °C in 20 s, it requires a redesign of the battery structure and the effect on battery safety is not clear.
