본 발명은 전기자동차의 충전배터리에 관한 것으로, 특히 온도가 낮을 경우 또는 장시간 주차시킨 상태에서 충전시 배터리를 예열시켜 충.방전 효율을 높이도록 하는 전기자동차의 배터리 예열장치에 관한 것이다.The present invention relates to a charging battery of an electric vehicle, and more particularly, to a battery preheating apparatus of an electric vehicle to increase the charging and discharging efficiency by preheating the battery when charging in a state of low temperature or parked for a long time.
일반적으로 전기자동차는 다수의 배터리에 전기에너지를 충전하고 그 충전된 에너지를 이용하여 전동기를 구동하고 기타 부하에 전원을 공급하여 주행하게 된다.In general, an electric vehicle charges a plurality of batteries with electrical energy, and uses the charged energy to drive an electric motor and supply power to other loads to drive.
따라서 에너지원으로서의 배터리의 역할은 대단히 중요한 반면, 온도에 따라 민감하게 성능 변화를 보이고 있다.Therefore, while the battery's role as an energy source is very important, the performance changes sensitively with temperature.
배터리 평가 결과에 따르면 배터리의 온도가 일정범위내에서는 높으면 높을 수록 충전 또는 방전량이 증가한다. 따라서 추운곳에 장시간 주차시킨 상태에서 충전할 경우 배터리 충전효율이 저하된다.According to the battery evaluation results, the higher the temperature of the battery within a certain range, the higher the charge or discharge amount. Therefore, when charging in a cold place for a long time, the battery charging efficiency is reduced.
그러나 현재 대부분의 전기자동차는 날씨가 춥거나 덥거나 관계없이 배터리를 차내에 설치된 상태로 충전 또는 방전함으로써 배터리 성능을 충분히 발휘하지 못하고 있는 실정이다.However, at present, most electric vehicles are not sufficiently performing battery performance by charging or discharging the battery while installed in the vehicle regardless of cold or hot weather.
본 발명은 이러한 점을 감안하여 안출된 것으로, 특히 충전시 외기 온도가 낮을 경우 충전하기 전에 배터리를 일정온도대 까지 예열시킨 후 충전함으로써 충.방전 효율을 높이도록 하는 전기자동차의 배터리 예열장치를 제공하는데 그 목적이 있다.The present invention has been made in view of this point, and in particular, when the external air temperature is low during charging, it provides a battery preheating device of an electric vehicle to increase the charging and discharging efficiency by pre-heating and then charging the battery to a certain temperature range before charging. Its purpose is to.
이러한 목적을 달성하기 위한 본 발명의 전기자동차의 배터리 예열장치는 배터리의 주위온도를 감지하는 온도감지센서와, 상기 온도감지센서로부터 인가된 배터리 온도 감지신호를 기준값과 비교하여 소정의 신호를 출력하는 비교기와, 상기 비교기의출력신호에 따라 릴레이를 절환하는 제어부와, 상기 제어부의 제어에 따라 예열수단과 충전기 중 어느한 곳에 전원을 공급하는 릴레이와, 상기 릴레이의 접속에 의해 전원이 인가되어 배터리를 예열시키는 배터리 예열수단으로 구성됨을 특징으로 한다.The battery preheating apparatus of the electric vehicle of the present invention for achieving the above object is to output a predetermined signal by comparing a temperature sensor and a battery temperature sensing signal applied from the temperature sensor and a reference value to detect the ambient temperature of the battery A comparator, a control unit for switching the relay according to the output signal of the comparator, a relay for supplying power to any one of the preheating means and the charger under the control of the control unit, the power is applied by the connection of the relay to the battery It is characterized by consisting of a battery preheating means for preheating.
상기 배터리 예열수단은 외주벽과 내주벽의 겹층구조로 이루어진 배터리 적재함을 형성하고, 상기 외주벽과 내주벽 사이에 절연체에 발열체가 포위되도록 구성되어 있다.The battery preheating means forms a battery stack having a laminated structure of an outer circumferential wall and an inner circumferential wall, and the heating element is surrounded by an insulator between the outer circumferential wall and the inner circumferential wall.
또한 상기 발열체는 일반 열선을 사용하여, 인가되는 교류전원에 의하여 주울열을 발생하게 되나, 경우에 따라서는 흑연 발열체나 또는 흑연 정도의 저항을 가진 다른 물질을 사용할 수도 있다.In addition, the heating element generates Joule heat by an alternating current power source using a common heating wire, but in some cases it may use a graphite heating element or another material having a resistance of the graphite.
이러한 구성에 의하면, 본 발명은 배터리에 충전하고자 충전플러그를 체결할 경우 배터리 온도가 낮으면 자동으로 릴레이가 발열체로 접속되어 배터리를 예열시키고, 이후 소정온도까지 예열되면 배터리로 접속되어 충전을 시작한다.According to this configuration, in the present invention, when the charging plug is fastened to charge the battery, when the battery temperature is low, the relay is automatically connected to the heating element to preheat the battery, and after the preheating to the predetermined temperature, the battery is connected to start charging. .

Are connected as possible. In the figure, reference numeral 10 denotes a charging plug, and 11 denotes a charging cable.
제2도는 본 발명의 배터리 적재함 구조를 보인 요부 확대단면도로써, 배터리 적재함(110)은 외주벽(101)과 내주벽(102)의 겹층구조로 이루어져 있으며, 상기 외주벽(101)과 내주벽(102) 사이에 절연체(103)에 포위된 발열체(104)가 적재함의 둘레방향에 걸쳐 설치된 구성으로 되며, 상기 발열체(104)에 교류전원이 인가되어 발열함으로써 배터리적재함(110)을 예열시키게 된다.Figure 2 is an enlarged cross-sectional view showing the main portion of the battery compartment of the present invention, the battery compartment 110 consists of a layer structure of the outer peripheral wall 101 and the inner peripheral wall 102, the outer peripheral wall 101 and the inner peripheral wall ( The heating element 104 surrounded by the insulator 103 between the 102 is configured to be installed over the circumferential direction of the stacking box, and AC power is applied to the heating element 104 to generate heat to preheat the battery compartment 110.
제3도는 본 발명의 배터리 예열장치를 보인 블럭회로도로써, 배터리의 주위온도를 감지하는 온도감지센서(150)와, 상기 온도감지센서(150)로 부터 인가된 배터리온도 감지신호를 기준값과 비교하여 소정의 신호를 출력하는 비교기(160)와, 상기 비교기(160)의 출력신호에 따라 릴레이를 절환하는 제어부(170)와, 상기 제어부(170)의 제어에 따라 예열수단과 충전기 중 어느한 곳에 전원을 공급하는 릴레이(140)로 구성되어 배터리 온도가 낮을 경우 배터리를 예열하고, 반대로 배터리 온도가 일정온도에 도달하면 스위치를 절환하여 충전을 하게 된다.3 is a block circuit diagram showing a battery preheating apparatus of the present invention, by comparing the temperature sensor 150 for detecting the ambient temperature of the battery and the battery temperature detection signal applied from the temperature sensor 150 with a reference value. A comparator 160 for outputting a predetermined signal, a control unit 170 for switching a relay according to the output signal of the comparator 160, and a power supply to any one of preheating means and a charger under control of the control unit 170 The relay 140 is configured to supply a preheating of the battery when the battery temperature is low, and conversely, when the battery temperature reaches a predetermined temperature, the switch is charged.
이와 같이 구성된 본 발명의 작용 및 효과를 설명하면, 배터리를 충전하고자 상용전원(AC)과 연결된 충전플러그(10)를 꽂으면 온도감지센서(150)에서는 배터리 온도를 감지하여 비교기(160)에 인가하게 된다.Referring to the operation and effect of the present invention configured as described above, if the charging plug 10 is connected to the commercial power (AC) to charge the battery, the temperature sensor 150 detects the battery temperature is applied to the comparator 160 Done.
비교기(160)는 배터리 온도와 설정온도인 기준값을 비교하여 배터리 온도가 기준값 보다 낮을 경우 하이신호를 출력하고 배터리 온도가 기준값 보다 높을 경우 로우신호를 출력하여 제어부(170)에 인가하게 되며, 제어부(170)에서는 비교기(160)의 출력신호에 따라 릴레이(140)를 절환시키게 된다.The comparator 160 compares the battery temperature with a reference value, which is a set temperature, outputs a high signal when the battery temperature is lower than the reference value, and outputs a low signal when the battery temperature is higher than the reference value, and applies the low signal to the controller 170. In 170, the relay 140 is switched according to the output signal of the comparator 160.
다시말해 배터리 온도가 기준값 보다 낮을 경우에는 릴레이(140)의 접점은 노말오픈단자(NO)에 접속되어 발열체(104)에 교류전원이 인가되고, 따라서 발열체(104)가 발열되면서 배터리 적재함(110)을 예열시켜 배터리 온도를 상승시키게 된다.In other words, when the battery temperature is lower than the reference value, the contact point of the relay 140 is connected to the normal open terminal NO so that the AC power is applied to the heating element 104, and thus the heating element 104 generates heat and loads the battery 110. Preheating will raise the battery temperature.
이러한 상태에서 배터리 온도가 점점 상승하여 지정온도에 도달하면, 즉, 배터리 온도가 비교기(160)의 기준값 보다 높아지게 되면, 제어부(170)에서는 릴레이(140)의 접점을 노말오픈단자(NO)에서 노말크로스단자(NC)로 절환시켜 충전기(130)에 교류전원을 인가하게 되며, 상기 충전기(130)는 교류전원을 직류전원으로 전환시켜 배터리(120)에 충전을 시작하게 된다.In this state, when the battery temperature gradually rises to reach the designated temperature, that is, when the battery temperature becomes higher than the reference value of the comparator 160, the controller 170 controls the contact point of the relay 140 to be normal at the normal open terminal NO. Switching to the cross terminal (NC) to apply the AC power to the charger 130, the charger 130 is to switch the AC power to DC power to start charging the battery 120.
이상에서 설명한 바와 같이, 본 발명은 배터리 온도가 낮을 경우 충전전원에 의해 미리 예열시킨 후 일정온도가 될 경우 배터리에 충전함으로써, 전기자동차의 배터리 충.방전 성능을 향상시켜 전기자동차에 한정된 에너지를 보다 효율적으로 활용할 수 있게 된다.As described above, the present invention improves the battery charging and discharging performance of the electric vehicle by preheating the battery by a charging power source when the battery temperature is low, and then charging the battery when the battery temperature reaches a predetermined temperature, thereby improving the energy limited to the electric vehicle. It can be utilized efficiently.
