Problems solved by technology

Therefore, although the battery in the floating charge state ensures that the backup power supply has a full charge at any time, it has a large energy loss; at the same time, due to the long-term heating of the battery under floating charge, the service life of the battery will be shortened.

Embodiment Construction

[0022] An additional circuit is connected between the storage battery and the DC bus, and the additional circuit is composed of a switch and a diode connected in parallel, and the on-off of the switch is controlled by the controller. When the switch is turned on, the DC power supply charges the battery, and when the switch is turned off, the battery is in a non-floating charging state. When the storage battery is in the standby state, the diode is reversely cut off, and when the storage battery supplies power to the load, the diode is turned on.

Abstract

The invention discloses a storage battery non-floating-charging hot standby technology, belongs to the technical field of electrical engineering and automation, and relates to a storage battery or storage battery pack running mode technology. According to the storage battery non-floating-charging hot standby technology, when a storage battery or a storage battery pack is used as a standby power source to run, the storage battery or the storage battery pack is not in the floating charging state. When a power source breaks down, and the storage battery or the storage battery pack needs to be switched to supply power, the storage battery or the storage battery pack can be immediately put into running, and the rapid seamless switching technology is achieved. Under the condition that the running performance of the storage battery or the storage battery pack is not affected, the running loss of the storage battery can be reduced, the service life of the storage battery is prolonged, and the economic performance of running of the storage battery is improved.

Description

technical field [0001] The present invention relates to a technology for the operation mode of a battery (including a battery pack, hereinafter referred to as a battery). Battery non-floating hot backup technology is a technology that the battery is not in the floating charge state when it is running as a backup power supply; when the power supply fails and needs to be switched to the battery power supply, it can be put into operation immediately to achieve rapid and seamless switching; Under the condition of affecting the operation performance of the storage battery, the operation loss of the storage battery can be reduced, and the economic performance of the operation of the storage battery can be improved; the invention belongs to the technical field of electrical engineering and automation thereof. Background technique [0002] Batteries are widely used as backup power sources in industrial fields such as power stations, substations, and communication stations. In the e...
