Description

Control method of a battery output control device equipped with a flood detection means {METHOD FOR CONTROLLING BATTERY OUTPUT WITH IMMERSION DETECTION MEANS}

The present invention relates to a control method of a battery output control device having a immersion detection means, and more particularly, to a battery-using device and immersion in which a failure of the battery-using device is neglected by shutting off the battery power when the battery is submerged. It relates to a control method of a battery output control device having a sensing means.

Electronic devices used outdoors are operated by power supply. However, among electronic devices, there are devices that must continue to operate even if the supply of electricity is interrupted due to a power outage or the like. These devices are equipped with an emergency backup battery for uninterrupted 24/7 operation.

However, when flooding occurs due to heavy rain, etc., the above design causes problems.

In the case of commercially supplied electricity, it is automatically cut off by a blocking device such as an earth leakage breaker in preparation for flooding. In the case of an emergency backup battery, it is intended to operate when commercial electricity is cut off, and there is no preparation for flooding.

In most cases, if moisture penetrates or floods the inside of an electronic device during operation, the internal circuit may be damaged, leading to a case where repair is impossible.

This is because, when a dielectric material called moisture penetrates in a state in which power is continuously supplied, a short circuit occurs in the internal circuit and the flowing voltage is changed, and in severe cases, the circuit elements are damaged.

Therefore, when a dielectric material is instantaneously introduced, such as immersion, a high level voltage is applied to a device operating at a low level voltage, and thus the device may be damaged. In addition, when an electrode providing a high voltage is connected to the ground electrode through low resistance water, a high current is instantaneously generated, which may give an impact to the line and driver of a finely and precisely designed circuit.

However, in the case of equipment that operates outdoors unattended, primitive methods such as manually shutting off the power in case of flooding cannot be used, so there is no preparation for flooding.

Therefore, the advantage of uninterrupted operation through the emergency backup battery is preserved, but in case of flooding, it detects the situation and automatically cuts off the battery power output to stop the operation of subsequent equipment to prevent damage to internal circuits and parts from flooding. You need skills.
