Description

Intuitive Energy Storage System (ESS) status display

The present invention relates to a state display device of the energy storage system (ESS), and more particularly, to detect the state information of the battery from the battery management system (BMS) for managing the battery state of the energy storage system (ESS), It is a device for dynamically displaying the state of the energy storage system (ESS) by gradually turning on the brightness, lighting direction and color conversion of the light emitting device according to the status information.

An Energy Storage System (ESS) is a device that improves power efficiency by storing produced electricity in storage devices such as batteries and supplying it when needed.This device includes batteries and batteries that collect electricity. There are related devices that manage it efficiently. Among them, a battery management system monitors the voltage, current, and temperature of the battery to maintain and manage the battery in an optimal state, and prevents overcharging and overdischarging when the battery is being charged and discharged, and the battery cell. By making the voltage of the liver uniform, it plays a role of improving energy efficiency and battery life. With the development of energy storage system (ESS) and battery management system (BMS) technology, the market of energy storage system (ESS) is gradually being applied to various fields.

The home energy storage system (ESS) can store the late-night power, reduce the electricity bill by using the power stored during the daytime, and can store and use the solar power generated during the daytime in the home installed solar.

The Energy Storage System (ESS) for UPS ensures that emergency lighting, which is necessary for safety, is on even in the event of a major power outage, and power can be supplied to major facilities. Therefore, it serves to supply emergency power required to solve the power supply failure.

Energy storage systems (ESS) are also used in power plants. In the case of energy storage systems used in power plants, the excess power is stored in the energy storage system (ESS) during times of low power demand, and then used during peak hours during the day, which reduces the overload of the power plants.

In the conventional method of displaying the state of the energy storage system (ESS) device, by controlling the light emitting device by an electrical signal from the battery management system (BMS) that manages the battery of the energy storage system (ESS), The state of the energy storage system (ESS) was checked by turning on the number of light emitting devices corresponding to the remaining amount (prior art 1) or by turning on the red or green light emitting devices (prior art 2) according to the battery state. Alternatively, the seven segment method (prior art 3) is displayed so that the user can check the state of the energy storage system (ESS) device.

However, conventional methods for displaying the state of the energy storage system (ESS) are provided with one or two light emitting devices to distinguish the state by the lighting color of the light emitting device or to use a plurality of light emitting devices. Since it is used to display the remaining amount of the battery, the user has difficulty in identifying the various states of the energy storage system (ESS).

Therefore, there is a need for a method of displaying various states of the energy storage system (ESS), and improving the user visibility and making it easy to judge.

Reference numeral 22 denotes a state where all three light emitting devices arranged vertically are turned on.

The state of charge is turned on in the direction of (20)-> (21)-> (22) by increasing the number of lighting of the light emitting device. Therefore, the charging state can be displayed by repeating the lighting as described in (20)-> (21)-> (22) to form an increasing number of lighting patterns.

On the other hand, the discharge state is turned on by decreasing the number of lighting of the light emitting device in the direction of (22)-> (21)-> (20). Accordingly, the discharge state can be displayed by repeating the lighting such as (22)-> (21)-> (20) to form the reduced number of lighting patterns.
