lisävirtalähde

Lisävirtalähde, meaning "additional power supply" in Finnish, refers to a secondary or backup power source used in conjunction with a primary one. This concept is broadly applicable across various fields, from electronics to vehicles and power grids. In electronics, a lisävirtalähde can be a battery pack for a laptop or a portable charger for a smartphone, providing power when the main AC adapter is unavailable or insufficient. It can also refer to a redundant power supply unit in critical systems like servers, ensuring continuous operation in case of a primary unit failure.

In the automotive industry, a lisävirtalähde might describe a secondary battery for accessories or an auxiliary power unit for specialized vehicles. For larger systems, such as a house or a power plant, a lisävirtalähde could be a generator, a solar panel array, or a UPS (uninterruptible power supply), designed to provide electricity during outages or fluctuations in the main supply. The purpose of a lisävirtalähde is typically to enhance reliability, extend operational time, or offer flexibility in power management. The specific type and capacity of a lisävirtalähde are determined by the requirements of the primary system and the expected power demands.
