Abstract

A system comprises a battery, a load and a power converter for converting battery power from the battery into load power for application to the load. A system controller enables selection between a continuous discharge mode and a discontinuous discharge mode of the battery. In this way, the battery can be operated in different ways according to the most appropriate battery discharge characteristics.

Description

technical field [0001] The invention relates to a system comprising a battery. Background technique [0002] Rechargeable batteries are used in many applications. They are used, for example, as temporary energy storage devices in systems with time-varying power output and time-varying energy input. For example, lighting fixtures are increasingly equipped with integrated batteries. These can be charged by solar energy, which is usually available when lighting is not needed and lighting is needed when solar energy is not. Therefore, they are used as energy storage elements to account for the time delay between the availability of charging energy and the demand for output power. [0003] Especially for outdoor lighting, but more generally for outdoor systems, the batteries are often exposed to ambient temperatures. [0004] The performance of rechargeable batteries such as lithium-ion (LiFePo4) batteries depends on stress parameters such as the maximum charge voltage per ce...
