Description

{High-voltage battery with Bluetooth Checking System}

The present invention relates to a high-voltage battery condition checking system and method using Bluetooth, and more particularly, to a high-voltage battery condition checking system and a checking method using Bluetooth that can monitor the battery condition from time to time using Bluetooth.

Of the various electrical components of an electric vehicle, the usable distance is determined according to the state of the individual cells of the battery, overcharge, over-discharge, internal and external temperature conditions, resulting in a drive stop due to a battery fault when an abnormality occurs. In order to repair the battery, there is a problem in that it is troublesome to remove and repair the battery located inside the vehicle.

Therefore, it is urgent to develop a device capable of checking the remaining life of the battery, the charging state voltage, the temperature, and the like from time to time in order to prevent overcharging of the battery.

The object of the present invention is to provide a high-voltage battery status checking system and a checking method using Bluetooth that can monitor the charged state, remaining service life, maximum voltage, minimum voltage, minimum temperature, maximum temperature, .

Another object of the present invention is to provide a high-voltage battery condition checking system and a checking method using Bluetooth that can prevent an electric vehicle from being monitored because it is monitored in real time.

A high-voltage battery status checking system and method for checking a high-voltage battery using Bluetooth according to the present invention is characterized in that a mobile terminal to which Bluetooth communication is applied searches for a vehicle, the vehicle transmits its information to the mobile terminal, A step in which the information is matched, a step in which the mobile terminal and the vehicle are interconnected, and a step in which the mobile terminal monitors the vehicle.

Step of the mobile terminal monitors the vehicle may be configured to determine the state of charge (State of Charge calculation), the remaining lifetime (State of Health estimation), maximum voltage, minimum voltage, minimum temperature, maximum temperature, single cells whether such and , Bluetooth is applied to the Internet or mobile phone so that the user can monitor it anywhere.

Also, in an electric vehicle operated using a battery, the battery may communicate with the user's mobile communication terminal through Bluetooth communication so that the status of the battery can be confirmed by the mobile communication terminal at a remote location. Charge calculation), the remaining lifetime (State of Health estimation), the maximum voltage, it is possible to prevent maintenance electric cars by checking in real time whether or not the minimum voltage, minimum temperature, maximum temperature, the abdomen can increase the life of electric vehicles.

According to the present invention, monitoring of a charged state of a battery, a remaining life, a maximum voltage, a minimum voltage, a minimum temperature, a maximum temperature, a short circuit and the like of a battery in a mobile terminal is monitored in real time, There is.

Yet another object of the present invention is to monitor and prevent an electric vehicle because it is monitored in real time, thereby increasing the service life of the electric vehicle.

4 is a block diagram of a high voltage battery condition check system using Bluetooth.

FIG. 1 is a state diagram showing data transmission between a mobile terminal and a battery of an electric vehicle, and FIG. 2 is a configuration diagram of a battery state checking system. Referring to FIG.

After the mobile terminal 1 searches for the user's vehicle section 2, the mobile terminal waits for a response of whether the user's vehicle is correct for the search of the vehicle section. After waiting for the connection, the vehicle unit transmits information of the vehicle to the mobile communication terminal when the vehicle of the user is right with the mobile terminal (S10). If the information of the vehicle is the user, the user's mobile terminal makes a connection request to the vehicle unit, and the vehicle unit makes a response to the connection request (S20).

After confirming that the user's vehicle is compatible with the user's vehicle, the Bluetooth connection is established and the vehicle unit and the mobile communication terminal are connected to each other to transmit data (S30).

The basic state of health estimation, state of charge calculation, Pack V, current, maximum voltage, minimum voltage, maximum temperature, minimum temperature, Fault), and the like, it can be shared with the vehicle unit. This can be configured so that the user can know the state of the battery through the mobile communication terminal.

FIG. 3 is a flowchart of a high-voltage battery condition check system using Bluetooth, and FIG. 4 is a block diagram of a high-voltage battery condition check system using Bluetooth. Referring to FIG.

After the Bluetooth of the mobile terminal searches for the user's vehicle section 210, the mobile terminal waits for a response indicating whether the user's vehicle is correct for the search of the vehicle section, waits for connection, If they match (220), the information of the vehicle is transmitted to the mobile communication terminal (230). When the information of the vehicle is the user, the user's mobile terminal makes a connection request to the vehicle unit, and the vehicle unit makes a response to the connection request.

After confirming that the user's vehicle is correct, when the vehicle is matched with the user's vehicle, the connection is made so that the vehicle unit and the mobile communication terminal can perform the data transmission by making the connection 240

The state of charge estimation, the state of charge calculation, Pack V, Current, maximum voltage, minimum voltage, maximum temperature, minimum value of battery, Temperature, fault history, and the like, and can be shared with the vehicle unit.

In operation S210, the mobile terminal searches for a vehicle part of the user (S210), transmits the information of the searched vehicle to the mobile terminal (S220), and confirms whether the information of the mobile terminal and the information of the vehicle coincide S230), a step of connecting the mobile terminal and the vehicle (S240), and a step S250 of transmitting data while the mobile terminal monitors the vehicle. The charging status of the battery may be transmitted through the mobile communication terminal By checking, the lifetime and the usable distance are determined according to the individual cell condition, capacity, overcharge, over discharge, internal temperature, external temperature, and condition of the battery. Therefore, it is necessary to monitor the battery condition and preventive maintenance There are advantages to be able to.
