Description

전기 자동차용 축전지의 환기팬 제어방법Ventilation fan control method for electric vehicle storage battery

본 발명은 전기 자동차의 축전지 환기팬에 관한 것으로서, 보다 상세하게는 전기 자동차에 탑재된 구동용 축전지의 보호하기 위한 축전지함에 고인 수소가스 또는 증발된 황산액을 배출하도록 구비된 환기팬의 구동을 충전완료 여부에 따라 제어함으로써, 충전이 끝났는데도 환기팬이 계속 구동되어 불필요한 전기를 소모하는 것을 방지하는 전기 자동차용 축전지의 환기팬 제어방법에 관한 것이다.The present invention relates to a battery ventilation fan of an electric vehicle, and more particularly, to charge a drive of a ventilation fan provided to discharge hydrogen gas or evaporated sulfuric acid accumulated in a battery compartment for protecting a driving battery mounted in an electric vehicle. The present invention relates to a control method of a ventilation fan of an electric vehicle storage battery which prevents consumption of unnecessary electricity by continuously driving the ventilation fan even after charging is completed.

일반적으로 전기 자동차의 축전지는 자동차를 축전지에 충전된 전기에 의하여 구동하는 전동기를 동력으로 하여 차량을 구동한다.In general, a battery of an electric vehicle drives a vehicle by using an electric motor for driving the vehicle by electricity charged in the battery.

여기서 차량을 구동하는 축전지는 납축전지와 알칼리 축전지가 있으며, 주로 납축전지를 사용하고 있다.Here, the storage battery for driving a vehicle includes a lead storage battery and an alkaline storage battery, and mainly uses a lead storage battery.

이와 같은 납 축전지는 여러개의 셀(Cell)로 이루어진 케이스가 있고, 각 셀마다 양극판과 음극판, 격리판 및 전해액이 들어 있다.Such a lead storage battery has a case composed of several cells, and each cell contains a positive electrode plate, a negative electrode plate, a separator plate, and an electrolyte solution.

또한 양극판은 음극판보다 작용이 활발하여 쉽게 파손되므로 화학적인 평형을 교려하여 음극판을 한 장 더 많이 둔다.In addition, since the anode plate is more active than the cathode plate and easily broken, the anode plate is placed one more sheet in consideration of chemical equilibrium.

여기서 극판은 납과 안티몬 합금제의 격자속에서 납산화물의 분말을 묽은 황산으로 반죽하여, 페이스트(paste)상태로 만든 것을 충전하여 건조시킨후 전기화학처리를 하면, 양극판은 다갈색의 과산화납(PbO2)으로, 음극판은 해면상납(Pb)의 작용물질로 변한다.Here, the electrode plate is kneaded with lead sulfate powder with dilute sulfuric acid in a lattice made of lead and antimony alloy, and then filled with a paste, dried and electrochemically treated. 2 ), the negative electrode plate turns into an agonist of sponges (Pb).

축전지에 사용되는 전해액은 무색, 무취의 순도 높은 묽은 황산이며, 축전지 내부의 화학작용을 돕고 각 극판 사이의 전류 전도의 기능을 한다.The electrolyte used in the battery is colorless, odorless and dilute sulfuric acid, which helps the chemical reaction inside the battery and conducts current conduction between each pole plate.

이와 같이 이루어진 전기 자동차용 납축전지는 충전시에만 가스발생 및 황산액의 증발이 일어나며 주행시 즉, 축전지 방전중에는 가스발생이 거의 없다. 따라서 밀폐된 축전지함에 수소가스가 고일 경우 예기치 않은 폭발사고를 일으킬 위험이 있으며, 또한 충전시 황산액의 증발로 인한 냄새가 실내로 유입되어 운전자 또는 탑승자로 하여금 불쾌감을 줄 수 있다. 이에 대비하여 축전지함에 환기팬을 설치하여 충전시 충전구함이 열리면 자동으로 환기팬이 구동되고, 충전구함이 닫히면 환기팬의 동작이 멈추게 된다.In the lead-acid battery for an electric vehicle made as described above, gas generation and sulfuric acid solution evaporate only during charging, and there is almost no gas generation during driving, that is, during battery discharge. Therefore, there is a risk of unexpected explosion accident when hydrogen gas is accumulated in the sealed battery box, and the smell caused by the evaporation of sulfuric acid solution may be introduced into the room, causing discomfort to the driver or passenger. In contrast, by installing a ventilation fan in the battery compartment, the charging fan is automatically opened when the charging compartment is opened during charging, and the operation of the ventilation fan is stopped when the charging compartment is closed.

그러나, 종래의 전기 자동차용 축전지 환기팬은 충전구 덮개 스위치에 의하여 동작되는 관계로 충전이 끝났는데도 충전구 덮개가 열려 있는 경우에는 환기팬이 계속 구동되어 불필요한 전기를 소모할 뿐만아니라 환기팬의 수명도 단축시키는 문제점이 있었다.However, since the conventional battery ventilation fan for an electric vehicle is operated by the charging port cover switch, when the charging port cover is open even after the charging is completed, the ventilation fan continues to be driven to consume unnecessary electricity as well as the life of the ventilation fan. There was also a problem of shortening.

따라서, 본 발명은 상기한 종래 기술의 문제점을 개선하고자 하여 전기 자동차에 탑재된 구동용 축전지의 보호하기 위한 축전지함에 고인 수소가스 또는 증발된 황산액을 배출하도록 구비된 환기팬의 구동을 충전완료 여부에 따라 제어함으로써, 충전이 끝났는데도 환기팬이 계속 구동되어 불필요한 전기를 소모하는 것을 방지하는 전기 자동차용 축전지의 환기팬 제어방법을 제공함에 그 목적이 있다.Therefore, the present invention is to complete the driving of the ventilation fan provided to discharge the hydrogen gas or evaporated sulfuric acid in the battery box to protect the driving battery mounted on the electric vehicle to improve the problems of the prior art described above. By controlling according to the above, an object of the present invention is to provide a method for controlling a ventilation fan of a storage battery for an electric vehicle that prevents consumption of unnecessary electricity by continuously driving a ventilation fan even after charging is completed.

상기한 본 발명의 목적을 달성하기 위한 전기 자동차용 축전지의 환기팬 제어방법은 전기 자동차용 축전지에 충전이 시작될 때 축전지의 전류를 검지하는 단계와; 상기 검지한 충전 전류가 설정된 전류 이상일 경우 환기팬을 구동하는 단계와; 상기 검지한 충전 전류가 설정된 전류 이하일 경우 환기팬의 구동을 정지시키는 단계로 이루어짐을 특징으로 한다.Ventilation fan control method for an electric vehicle battery for achieving the above object of the present invention comprises the steps of: detecting the current of the battery when charging the electric vehicle battery; Driving a ventilation fan when the detected charging current is equal to or greater than a set current; When the detected charging current is less than the set current, characterized in that the step of stopping the drive of the ventilation fan.

도 2는 본 발명에 따른 전기 자동차용 축전지 환기팬 제어과정의 흐름도로서, 이에 도시된 바와 같이 충전 신호발생에 따라 축전지의 충전시작을 검지하는 단계와; 상기 축전지의 충전이 시작됨에 따라 축전지의 충전전류를 검지하는 단계와; 상기 축전지로부터 충전 전류가 검출되거나, 설정된 기준값 이상 전류가 검지될 경우 환기팬을 구동시키는 단계와; 상기 축전지로부터 충전 전류가 검출되지않거나, 설정된 기준값 이하의 전류가 검지될 경우 환기팬의 구동을 정지시키는 단계로 이루어진다.2 is a flowchart of a control process of a battery ventilation fan for an electric vehicle according to the present invention, the method comprising: detecting a start of charging of a battery according to a charging signal as shown in the drawing; Detecting charging current of the battery as charging of the battery starts; Driving a ventilation fan when a charging current is detected from the battery or a current exceeding a set reference value is detected; When the charging current is not detected from the battery or a current below the set reference value is detected, the driving of the ventilation fan is stopped.

이와 같이 이루어진 본 발명의 작용을 첨부된 도 1, 도 2를 참조하여 상세히 설명하면 다음과 같다.Referring to the operation of the present invention made as described above with reference to Figures 1 and 2 as follows.

먼저, 차량 제어기(101)에서는 충전신호 발생부(102)에서 충전신호가 발생될 경우 즉, 축전지에 충전이 시작될 경우 축전지 일측에 구비된 축전지 전류센서(103)를 구동시켜, 축전지에서 발생되는 전류를 검출하게 된다.First, when the charging signal is generated by the charging signal generator 102, that is, when charging is started in the battery, the vehicle controller 101 drives the battery current sensor 103 provided at one side of the battery to generate a current generated in the battery. Will be detected.

전기 자동차용 축전지에 충전이 시작되면 충전신호 발생부(102)로부터 발생되는 충전신호가 차량 제어기(101)에 출력되고, 차량 제어기(101)에서는 충전신호 발생부(102)로부터 발생된 충전신호가 입력됨에 따라 축전지 전류센서(103)를 구동시킨다.When charging is started in the battery for an electric vehicle, the charging signal generated from the charging signal generator 102 is output to the vehicle controller 101, and the charging signal generated from the charging signal generator 102 is output from the vehicle controller 101. As input, the battery current sensor 103 is driven.

축전지 전류센서(103)를 통해 전류가 검지됨에 따라 현재 축전지를 충전중임을 인지한다.As the current is detected through the battery current sensor 103, it is recognized that the battery is currently being charged.

여기서 축전지 전류센서(103)에서 검지된 전류값이 설정된 전류값 이상일 경우 축전지가 현재 충전중임을 판단하게 된다.Here, when the current value detected by the battery current sensor 103 is greater than or equal to the set current value, it is determined that the battery is currently being charged.

이와 같이 차량 제어기(101)에서 현재 축전지가 충전중이라고 판단될 경우 배터리함(105)의 일측에 구비된 환기팬(104)을 구동시킨다.As such, when the vehicle controller 101 determines that the storage battery is currently being charged, the ventilation fan 104 provided at one side of the battery compartment 105 is driven.

환기팬(104)이 차량 제어기(101)의 제어에 의하여 구동됨에 따라 충전중에 발생되는 수소가스, 황산액등을 외부로 배출하게 된다.As the ventilation fan 104 is driven by the control of the vehicle controller 101, hydrogen gas, sulfuric acid, and the like, generated during charging, are discharged to the outside.

축전지의 충전이 완료된 경우에는 차량 제어기(101)의 제어에 의하여 환기팬(104)의 구동을 정지시킨다.When charging of the battery is completed, the driving of the ventilation fan 104 is stopped by the control of the vehicle controller 101.

즉, 차량 제어기(101)는 축전지 전류센서(103)에서 검지된 전류값이 검출되지 않거나, 설정된 기준치 이하로 떨어질 경우 충전이 완료되었음을 판단하고, 환기팬(104)의 구동을 정지시킨다.That is, the vehicle controller 101 determines that the charging is completed when the current value detected by the battery current sensor 103 is not detected or falls below the set reference value, and stops the driving of the ventilation fan 104.

이상에서 설명한 바와 같이 본 발명은 전기 자동차에 탑재된 구동용 축전지의 보호하기 위한 축전지함에 고인 수소가스 또는 증발된 황산액을 배출하도록 구비된 환기팬의 구동을 충전완료 여부에 따라 제어함으로써, 충전이 끝났는데도 환기팬이 계속 구동되어 불필요한 전기를 소모하는 것을 방지할 수 있을 뿐만 아니라, 환기팬의 수명을 연장시킬 수 있는 효과가 있다.As described above, the present invention controls the driving of the ventilation fan provided to discharge hydrogen gas or evaporated sulfuric acid accumulated in the battery box for protecting the driving battery mounted on the electric vehicle, depending on whether the charging is completed. Even when the ventilation fan is driven continuously, it is possible to prevent unnecessary consumption of electricity and to extend the life of the ventilation fan.

한편, 본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
