A rechargeable battery designed to power machines and vehicles.
Traction batteries are designed to cope well with many charging cycles, even up to the final discharge voltage, because they are usually charged once and then used until they are empty or nearly empty, and only then recharged. They deliver even amounts of current over a long period of time.
The same properties are needed for stationary applications. They are therefore also well suited as intermediate storage for photovoltaic or wind power systems or for safety-relevant applications that are to be independent of the power grid (uninterruptible power supply/USV).
