r4から構成されている。 It is constructed from r4. またコントローラ19は温度センサ18からの温度信号からバッテリ温度を検出するバッテリ温度検出部19aと、検出されたバッテリ温度を適正温度帯との関連で評価する高温検出部19b及び低温検出部19cから構成されている。 The controller 19 consists of a battery temperature detecting section 19a and the high-temperature detecting portion 19b evaluates the detected battery temperature in relation to the proper temperature zone and the low-temperature detecting unit 19c that detects a battery temperature from a temperature signal from the temperature sensor 18 It is. 【0015】次に、上記構成の電気自動車用バッテリの温度調節装置の動作について説明する。 [0015] Next, the operation of the temperature control device for an electric vehicle battery of the above-described configuration. 図2の回路図に示すように、温度センサ18によってバッテリ液温度を監視し、その検出信号をコントローラ19に入力する。 As shown in the circuit diagram of FIG. 2, the battery fluid temperature is monitored by the temperature sensor 18, and inputs the detection signal to the controller 19.
コントローラ19では、バッテリ温度検出部19aにおいて温度信号からバッテリ温度Tbを検出し、その検出温度Tbを高温検出部19b及び低温検出部19cに与え、ここであらかじめ設定されている適正温度帯[T The controller 19 detects a battery temperature Tb from the temperature signal in the battery temperature detection unit 19a, given the detected temperature Tb to a high temperature detecting portion 19b and the low-temperature detecting portion 19c, where appropriate are preset temperature zone [T

下限温度Tcより低くないか、適正温度帯内にあるかを判断する。 It does not lower than the lower limit temperature Tc, determines it is within the proper temperature zone. 【0016】いまバッテリ温度Tbが高くて適正温度帯の上限温度Thを超えている場合、バッテリを冷却する必要があるので、高温検出部19bにおいて(Tb−T [0016] If the current battery temperature Tb exceeds the upper limit temperature Th of the proper temperature zone is high, it is necessary to cool the battery, the high temperature detector 19b (Tb-T

cで示す方向にゲート信号2,3のデューティ比で定められる大きさの電流が流れる。 The magnitude of the current determined by the duty ratio of the gate signal 2 flows in the direction indicated c. In これと同時に、高温検出部19bはファンオン信号5を出力し、これによってスイッチングトランジスタ20もオンして冷却ファン14 At the same time, the high-temperature detecting unit 19b outputs a fan-on signal 5, the cooling fan 14 thereby switching transistor 20 is also turned on
が起動される。 There is started. 【0017】こうしてペルチェ素子伝熱板12に冷却用電流Icが流れ、冷却ファン20が起動されると、図3 [0017] Thus the cooling current Ic flows through the Peltier element heat transfer plate 12, the cooling fan 20 is started, FIG. 3
に示すように、ペルチェ素子伝熱板12はバッテリ2に密着している内側が吸熱、放熱フィン15が取り付けられている外側が発熱し、バッテリ2の熱を吸熱して放熱フィン15まで伝達し、ここで冷却ファン14によってダクト部13を通流するようになった空気に放熱し、各バッテリ2を冷却することになる。 As shown in, the Peltier element heat transfer plate 12 outside is heated inner endothermic, the heat radiation fin 15 is attached, which is in close contact with the battery 2 and transmit the heat battery 2 to the radiating fin 15 by absorbing heat , wherein the cooling fan 14 dissipates heat to the air that has become the duct portion 13 as flowing through, so that each battery 2 is cooled. 【0018】逆に図2に示した回路図において、バッテリ温度Tbが適正温度帯[Th,Tc]に対してその下限温度Tcよりも低い場合、コントローラ19の低温検出部19cが下限温度Tcとバッテリ温度Tbとの差の大きさに応じたデューティ比のゲート信号1,4をトランジスタTr1,Tr4に出力し、電流方向切替回路部1 [0018] In the circuit diagram shown in reverse in FIG 2, the battery temperature Tb is proper temperature zone [Th, Tc] is lower than the lower limit temperature Tc with respect to low-temperature detecting portion 19c of the controller 19 and the lower limit temperature Tc the gate signal 1,4 having a duty ratio corresponding to the magnitude of the difference between battery temperature Tb and output to the transistor Tr1, Tr4, the current direction switching circuit portion 1
7のトランジスタTr1,Tr4のスイッチングを行う。 7 perform the switching of the transistors Tr1, Tr4 of. これによって、トランジスタTr1,Tr4がオンとする時にペルチェ素子伝熱板12に矢印Ihで示す方向にゲート信号1,4のデューティ比で定められる大きさの電流が流れる。 Thus, the transistors Tr1, Tr4 are the magnitude of the current flow that is determined by the duty ratio of the gate signals 1,4 in the direction indicated by the Peltier element heat transfer plate 12 in the arrow Ih when turned on. 【0019】こうしてペルチェ素子伝熱板12に加熱用電流Ihが流れると、図4に示すように、ペルチェ素子伝熱板12はバッテリ2に密着している内側が発熱し、 [0019] Thus the heating current Ih flows in the Peltier element heat transfer plate 12, as shown in FIG. 4, a Peltier element heat transfer plate 12 generates heat inside, which is in close contact with the battery 2,
放熱フィン15が取り付けられている外側が吸熱し、これによって各バッテリ2を加熱することになる。 Absorbs the outer heat dissipating fin 15 is mounted, thereby resulting in heating the respective battery 2. 【0020】そしてコントローラ19のバッテリ温度検出部19aが検出するバッテリ温度Tbが適正温度帯[Th,Tc]の範囲内であれば、高温検出部19bも低温検出部19cもゲート信号を出力せず、バッテリ2 [0020] The battery temperature Tb is proper temperature range in which the battery temperature detecting unit 19a of the controller 19 detects [Th, Tc] Within the scope of the high-temperature detecting portion 19b also does not output the even gate signal low temperature detector 19c , the battery 2
は加熱、冷却いずれも行われないことになる。 Heating, will not do any cooling. 【0021】このようにしてこの実施例の電気自動車用バッテリの温度調節装置によれば、ペルチェ素子を利用してそこに通流させる電流方向をバッテリ温度が高温時には冷却する方向に、逆に低温時には加熱する方向に切替える制御を行うようにしているので、放熱効果が高いペルチェ素子を用いてバッテリを冷却することができると共に、必要な場合には加熱することもでき、従来から用いられてきた加熱用のヒータに使用する電流量と同じ程度の電流量でバッテリの温度調節をすることができるようになる。 According this way the temperature control apparatus for an electric vehicle battery of this embodiment, the current direction of flow through therein by utilizing the Peltier element in the direction in which the battery temperature is cooled at high temperatures, low temperatures in the opposite since sometimes to perform the control to switch the direction of heating, it is possible to cool the battery with the heat dissipation effect is high Peltier element, if necessary can be heated, has been used conventionally it is possible to the temperature control of the battery at the current amount of the same extent as the amount of current used for the heater for heating. 【0022】なお、上記実施例では適正温度帯[Th, [0022] In addition, the proper temperature zone in the above embodiment [Th,
Tc]の上限温度Thとバッテリ温度Tbとの差の大きさ、また下限温度Tcとバッテリ温度Tbとの差の大きさによって電流方向切替用のスイッチングトランジスタのゲート信号のデューティ比を制御し、流れる冷却用電流Icや加熱用電流Ihの大きさを可変制御するようにしたが、これには特に限定されず、高温時、低温時それぞれにおいて一定の電流を通流させる簡単な構成とすることもできる。 Magnitude of the difference between the upper limit temperature Th and the battery temperature Tb Tc], also controls the duty ratio of a gate signal of the switching transistor for current direction switching by the magnitude of the difference between the lower limit temperature Tc and battery temperature Tb, flows the size of the cooling current Ic and the heating current Ih to have been adapted to variably control, this is not particularly limited, high temperature, also a simple structure and to flow through the constant current at the low temperature, respectively it can. 【0023】また、複数のバッテリそれぞれに対応してコントローラ19を設け、個別に温度調節する構成とすることもできる。 Further, the controller 19 provided corresponding to the plurality of batteries may also be configured to the temperature adjusted individually. 【0024】 【発明の効果】以上のように請求項1の発明によれば、 According to the invention of claim 1 as described above, according to the present invention,
常にバッテリ温度を測定して適正温度帯と比較し、バッテリ温度が適正温度帯を超える高温状態にあると判定する時には、ペルチェ素子の放熱フィンと接触する外側を発熱させ、バッテリに密着する内側が吸熱する方向に電流を流すように電流の通電方向を切替制御し、同時に冷却ファンを起動し、これによってバッテリの発熱をペルチェ素子で吸熱して放熱フィンから放熱させ、バッテリ温度を下げるようにし、逆にバッテリ温度が適正温度帯に達しない低温状態にあると判定する時には、ペルチェ素子のバッテリに密着する内側が発熱する方向に電流を流すように電流の通電方向を切替制御し、これによってバッテリをペルチェ素子の発熱によって加熱してバッテリ温度を上昇させるようにしているので、放熱効率の良いペルチェ素子を Always measures battery temperature as compared with proper temperature range, when determined to be in a high temperature when the battery temperature exceeds a proper temperature zone, exothermed outer contacting the heat dissipating fins of the Peltier element, the inner in close contact with the battery and switching control of the current direction of the current so as to flow a current in the direction of heat absorption, start the cooling fan at the same time, whereby the refrigerant absorbs heat to heat generation of the battery by the Peltier element is radiated from the heat radiation fins, so as to lower the battery temperature, when the battery temperature conversely is determined that the low temperature does not reach the proper temperature zone, the flowing direction of the current so as to flow a current in a direction inwardly in close contact with the battery of the Peltier element generates heat by switching control, whereby the battery since so as to increase the heated battery temperature due to heat generation of the Peltier device, the heat radiation efficient Peltier element 用してバッテリの温度調節を行うことができ、従来のように大容量の冷却ファンを用いなくても、ヒーターで加熱する場合に必要とされる電力と同じ程度の電力でバッテリに対する加熱、冷却による温度調節ができる。 And use can adjust the temperature of the battery, without using a cooling fan of a large capacity as in the prior art, the heating to the battery at a power of the same degree as the power required when heating with a heater, cooling the temperature can be adjusted by. 【0025】請求項2の発明によれば、バッテリ適正温度帯とバッテリ実温度との差の大きさを求め、この差の大きさに応じて加熱電流又は冷却電流制御を行うようにしているので、バッテリ温度の調節が精度良く行える。 According to the invention of claim 2, we obtain the magnitude of the difference between the battery proper temperature range and the battery actual temperature, since to perform the heating current or cooling current control in accordance with the magnitude of this difference , it performed better regulation of the battery temperature accuracy.
