Description

本発明は、互いに直列接続された複数個のキャパシタセルやバッテリーセルなどの蓄電セルを備えた蓄電装置において、寒冷地などにおいて蓄電セルの温度が低下している場合に、蓄電セルを温度調整するための蓄電セル温度調整回路及び当該蓄電セル温度調整回路を備えた蓄電装置に関する。   According to the present invention, in a power storage device including a plurality of power storage cells such as capacitor cells and battery cells connected in series with each other, the temperature of the power storage cell is adjusted when the temperature of the power storage cell is lowered in a cold region or the like. The present invention relates to a power storage cell temperature adjustment circuit for power storage and a power storage device including the power storage cell temperature adjustment circuit.

複数個の電気二重層キャパシタやリチウムイオンキャパシタなどが直列接続されたキャパシタセルや、複数個のリチウムイオンバッテリーなどが直列接続されたバッテリーセルなどの蓄電セルは、キャパシタやバッテリーの温度が低いと静電容量が低下し、放電量が低下してしまうことが知られている。   A storage cell such as a capacitor cell in which a plurality of electric double layer capacitors or lithium ion capacitors are connected in series or a battery cell in which a plurality of lithium ion batteries are connected in series is static when the temperature of the capacitor or battery is low. It is known that the electric capacity decreases and the discharge amount decreases.

図３は、定格容量９００Ｆのリチウムイオンキャパシタにおける、温度と静電容量の関係を示すグラフである。図３に示すように、リチウムイオンキャパシタは２０℃以下になると静電容量が低下し始め、−４０℃では静電容量が定格容量の半分以下にまで低下してしまい、寒冷地などにおいては、蓄電セルの性能を十分に発揮させることが困難となる。   FIG. 3 is a graph showing the relationship between temperature and capacitance in a lithium ion capacitor having a rated capacity of 900F. As shown in FIG. 3, the lithium ion capacitor starts to decrease in capacitance when it is 20 ° C. or lower, and the capacitance decreases to less than half of the rated capacity at −40 ° C. It becomes difficult to fully demonstrate the performance of the storage cell.

また、蓄電セルを充電する場合にも、蓄電セルの温度が低下し静電容量が低下した状態であると、同じ電圧で充電しても、常温付近での静電容量が大きい場合と比べて充電できる電荷量が低下してしまい、十分に蓄電セルを充電することができない。   Also, when charging a storage cell, if the temperature of the storage cell is lowered and the capacitance is reduced, even if it is charged at the same voltage, compared with the case where the capacitance near room temperature is large The amount of charge that can be charged is reduced, and the storage cell cannot be fully charged.

このため、蓄電セルを有する蓄電装置に対して熱結合状態に配置された冷却通路（特許文献１）や、蓄電装置の内部を流通する冷却水が循環する循環回路（特許文献２）を備えることによって、蓄電装置の温度が低い場合に冷却通路や循環回路内を流れる冷却水などの冷媒を加熱することで蓄電装置を温度調整することが行われている。   For this reason, it is provided with a cooling passage (Patent Document 1) arranged in a thermal coupling state with respect to the power storage device having the power storage cell, and a circulation circuit (Patent Document 2) through which cooling water flowing inside the power storage device circulates. Thus, when the temperature of the power storage device is low, the temperature of the power storage device is adjusted by heating a coolant such as cooling water flowing in the cooling passage or the circulation circuit.

しかしながら、このように冷却通路や循環回路などを用いて蓄電装置を温度調整するためには、冷媒を加熱するための凝縮器やコンプレッサなどが必要となるため高コストであるうえ、蓄電装置を温度調整するためのシステムとしてサイズが大きくなり、重くなってしまっていた。   However, in order to adjust the temperature of the power storage device using a cooling passage or a circulation circuit as described above, a condenser, a compressor, or the like for heating the refrigerant is required. As a system to adjust, the size has become larger and heavier.

さらに、複数の蓄電セルを積層させた蓄電装置の場合、外側に配置された蓄電セルを温めることは可能だが、内側に配置された蓄電セルまで熱が届かないため、外側の蓄電セルと内側の蓄電セルとによって温度差が生じ、静電容量にばらつきが生じてしまっていた。   Furthermore, in the case of a power storage device in which a plurality of power storage cells are stacked, it is possible to warm the power storage cells arranged on the outside, but heat does not reach the power storage cells arranged on the inner side. A temperature difference was generated depending on the storage cell, resulting in variations in capacitance.

また、リチウムイオンキャパシタやリチウムイオンバッテリーなどでは、ラミネートセルと呼ばれる形態の蓄電セルが用いられることがあるが、ラミネート外装の熱伝導性が低く、冷却通路や循環回路などによってラミネートセルの外部から温度調整しようとしても温まりにくかった。   In addition, in a lithium ion capacitor or a lithium ion battery, a storage cell called a laminate cell is sometimes used. However, the thermal conductivity of the laminate exterior is low, and the temperature from the outside of the laminate cell is reduced by a cooling passage or a circulation circuit. It was hard to get warm even when trying to adjust.

本発明はこのような現状を鑑み、冷媒を加熱するための凝縮器やコンプレッサなどが不要となり、低コストであるうえ、蓄電装置を温度調整するためのシステムとしてサイズが大きくなることがなく、軽量化を図ることができる蓄電セル温度調整回路及び当該蓄電セル温度調整回路を備えた蓄電装置を提供することを目的とする。   In view of such a current situation, the present invention eliminates the need for a condenser, a compressor, and the like for heating the refrigerant, is low in cost, and does not increase in size as a system for adjusting the temperature of the power storage device. It is an object of the present invention to provide a storage cell temperature adjustment circuit capable of achieving the above and a storage device including the storage cell temperature adjustment circuit.

It is an object to provide a power storage device including an adjustment circuit.

FIG. 1 is a circuit configuration diagram of a power storage device including a power storage cell temperature adjustment circuit according to the present invention.

本実施例の蓄電装置１０の蓄電セル温度調整回路１４は、キャパシタセルＣ1〜Ｃnに対してそれぞれ並列に接続された温度調整装置Ｒr1〜Ｒrn及びＦＥＴ（Field Effect Transistor；電界効果トランジスタ）からなる温度調整用スイッチＳr1〜Ｓrnと、キャパシタセルＣ1〜Ｃnのセル電圧をそれぞれ検出するためのセル電圧検出回路及び後述する均等化制御を行うキャパシタセルＣ1〜Ｃnに対して並列に接続された均等化制御用スイッチＳe1〜Ｓenを制御するための均等化セル選択回路を含む均等化ＩＣ１６と、均等化ＩＣ１６及び温度調整用スイッチＳr1〜Ｓrnを制御するための演算処理装置１８と、キャパシタセルＣ1〜Ｃnから演算処理装置１８を動作させるための電力を供給するための電源回路２０とから構成されている。 The storage cell temperature adjustment circuit 14 of the storage device 10 of this embodiment includes temperature adjustment devices R r1 to R rn and FETs (Field Effect Transistors) connected in parallel to the capacitor cells C 1 to C n , respectively. and a temperature adjusting switch S r1 to S rn consisting), the capacitor cells C 1 -C n to perform cell voltage detection circuit and equalization control described later for detecting respective cell voltages of the capacitor cells C 1 -C n The equalization IC 16 including an equalization cell selection circuit for controlling the equalization control switches S e1 to S en connected in parallel to each other, and the equalization IC 16 and the temperature adjustment switches S r1 to S rn are controlled. And a power supply circuit 20 for supplying electric power for operating the arithmetic processing device 18 from the capacitor cells C 1 to C n .

温度調整装置Ｒr1〜Ｒrnとしては、キャパシタセルＣ1〜Ｃnの電流を消費するものであれば特に限定されず、例えば、抵抗器や高調波発生器などを用いることができる。本実施例では、温度調整装置として、温度調整用抵抗Ｒr1〜Ｒrnを用いて説明する。 The temperature adjusting devices R r1 to R rn are not particularly limited as long as they consume currents of the capacitor cells C 1 to C n , and for example, resistors and harmonic generators can be used. In the present embodiment, description will be made using temperature adjusting resistors R r1 to R rn as the temperature adjusting device.

また、本実施例の蓄電装置１０には、キャパシタセルＣ1〜Ｃnにおいて、セル間の電圧のバラツキを補正するための均等化制御回路１２を設けている。均等化制御回路１２は、キャパシタセルＣ1〜Ｃnに対してそれぞれ並列に接続された均等化制御用抵抗Ｒe1〜Ｒen及びＦＥＴからなる均等化制御用スイッチＳe1〜Ｓenと、前述した均等化ＩＣ１４と演算処理装置１８と電源回路２０とから構成されている。 Further, the power storage device 10 of the present embodiment is provided with an equalization control circuit 12 for correcting the voltage variation between the cells in the capacitor cells C 1 to C n . The equalization control circuit 12 includes equalization control resistors R e1 to R en and FETs that are connected in parallel to the capacitor cells C 1 to C n , respectively, and equalization control switches S e1 to S en . The equalization IC 14, the arithmetic processing unit 18, and the power supply circuit 20 are configured.

均等化制御回路１２は、蓄電セルにセル間電圧のバラツキが生じると、特定の蓄電セルに電圧が集中することにより蓄電セルの寿命が短くなってしまうという問題を解消するために設けられる回路であり、本実施例では、キャパシタセルＣ1〜Ｃnに対してそれぞれ並列に接続された均等化制御用抵抗Ｒe1〜ＲenとＦＥＴからなる均等化制御用スイッチＳe1〜Ｓenとから構成されているが、これに限定されず、既存の均等化制御回路を用いることができる。 The equalization control circuit 12 is a circuit provided to solve the problem that the life of a power storage cell is shortened due to the concentration of the voltage in a specific power storage cell when a variation in the voltage between the cells occurs in the power storage cell. In this embodiment, the equalization control resistors R e1 to R en connected in parallel to the capacitor cells C 1 to C n and the equalization control switches S e1 to S en comprising FETs are provided. However, the present invention is not limited to this, and an existing equalization control circuit can be used.

本実施例の均等化制御回路１２では、蓄電装置１０の休止中に、均等化ＩＣ１６のセル電圧検出回路によってキャパシタセルＣ1〜Ｃnのセル電圧を測定し、セル電圧が高いキャパシタセルに対して並列に接続された均等化制御用スイッチＳe1〜Ｓenを、演算処理装置１８からの命令に従って均等化ＩＣ１６の均等化セル選択回路によって入状態とする。これによって、セル電圧が高いキャパシタセルの電荷を均等化制御用抵抗Ｒe1〜Ｒenによって消費して電圧を下げることができる。 In the equalization control circuit 12 of the present embodiment, the cell voltage of the capacitor cells C 1 to C n is measured by the cell voltage detection circuit of the equalization IC 16 while the power storage device 10 is stopped, and the capacitor cell having a high cell voltage is measured. Then, the equalization control switches S e1 to S en connected in parallel are turned on by the equalization cell selection circuit of the equalization IC 16 in accordance with a command from the arithmetic processing unit 18. As a result, the charge of the capacitor cell having a high cell voltage can be consumed by the equalization control resistors R e1 to R en to lower the voltage.

また、本実施例では、温度調整用スイッチＳr1〜Ｓrn及び均等化制御用スイッチＳe1〜ＳenとしてＦＥＴを用いているが、これに限定されず、ダイオードスイッチやＭＥＭＳ（Micro Electro Mechanical Systems）スイッチなどの高周波スイッチなど、演算処理装置１８や均等化セル選択回路（本実施例の場合は、均等化ＩＣ１６）の出力に基づいて入切を制御できるスイッチを用いることができる。 In this embodiment, FETs are used as the temperature adjustment switches S r1 to S rn and the equalization control switches S e1 to S en . However, the present invention is not limited to this, but a diode switch or MEMS (Micro Electro Mechanical Systems) is used. ) A switch capable of controlling on / off based on the output of the arithmetic processing unit 18 or the equalization cell selection circuit (in the present embodiment, the equalization IC 16), such as a high-frequency switch such as a switch, can be used.

また、本実施例では、セル電圧検出回路及び均等化セル選択回路などを含む均等化ＩＣ１６（例えば、リニアテクノロジー社製ＬＴＣ６８０２）を用いているが、セル電圧検出回路及び均等化セル選択回路をそれぞれ独立して構成してもよい。   In this embodiment, an equalization IC 16 (for example, LTC6802 manufactured by Linear Technology Co., Ltd.) including a cell voltage detection circuit and an equalization cell selection circuit is used. However, the cell voltage detection circuit and the equalization cell selection circuit are respectively used. You may comprise independently.

また、演算処理装置１８は、ＣＰＵ（Central Processing Unit；中央演算処理装置）やＲＡＭ（Random Access Memory；ランダムアクセスメモリ）、演算処理プログラムが記憶されたＲＯＭ（Read Only Memory；リードオンリーメモリ）などによって構成されている。   The arithmetic processing unit 18 is constituted by a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory) in which an arithmetic processing program is stored, and the like. It is configured.

また、電源回路２０は、キャパシタセルＣ1〜Ｃnから演算処理装置１８を動作させるための電力を供給するための回路であり、例えば、ＤＣ−ＤＣコンバータなどを含んで構成されている。 The power supply circuit 20 is a circuit for supplying power for operating the arithmetic processing unit 18 from the capacitor cells C 1 to C n , and includes, for example, a DC-DC converter.

一方、蓄電装置１０の蓄電部２２は、蓄電セルとしてリチウムイオンキャパシタからなるｎ個のキャパシタセルＣ1〜Ｃnが直列接続されて構成される。蓄電部２２の両端は電源回路２０に接続されており、キャパシタセルＣ1〜Ｃnの電力を用いて演算処理装置１８を動作させるように構成されている。すなわち、本実施例の蓄電セル温度調整回路１４を備えた蓄電装置１０は、蓄電装置１０自身の電力を用いて蓄電セルの温度調整を行うことができる。 On the other hand, the power storage unit 22 of the power storage device 10 is configured by connecting n capacitor cells C 1 to C n made of lithium ion capacitors in series as power storage cells. Both ends of the power storage unit 22 are connected to the power supply circuit 20 and are configured to operate the arithmetic processing unit 18 using the power of the capacitor cells C 1 to C n . That is, the power storage device 10 provided with the power storage cell temperature adjustment circuit 14 of the present embodiment can adjust the temperature of the storage cell using the power of the power storage device 10 itself.

このように構成された本実施例の蓄電セル温度調整回路１４では、昇温用スイッチＳr1〜Ｓrnが入状態となると、キャパシタセルＣ1〜Ｃnから温度調整用抵抗Ｒr1〜Ｒrnに対してそれぞれ電流が流れる。 In the storage cell temperature adjustment circuit 14 of the present embodiment configured as described above, when the temperature rising switches S r1 to S rn are turned on, the temperature adjustment resistors R r1 to R rn from the capacitor cells C 1 to C n. Current respectively flows.

この電流の消費によって、キャパシタセルＣ1〜Ｃn自身が発熱し、キャパシタセルＣ1〜Ｃnが昇温されることになる。このように、キャパシタセルＣ1〜Ｃn自身の発熱によって昇温するためには、大きな電流が流れるようにする必要があるため、温度調整用抵抗Ｒr1〜Ｒrnとしては、均等化制御用抵抗Ｒe1〜Ｒenと比べて小さな抵抗値とする必要がある。温度調整用抵抗Ｒr1〜Ｒrnの抵抗値としては、蓄電セルの種類や定格容量などによって適宜設定することができる。 Due to the consumption of this current, the capacitor cells C 1 to C n themselves generate heat, and the temperature of the capacitor cells C 1 to C n is increased. Thus, in order to raise the temperature by the heat generation of the capacitor cells C 1 to C n itself, it is necessary to allow a large current to flow. Therefore, the temperature adjustment resistors R r1 to R rn are used for equalization control. It is necessary to make the resistance value smaller than the resistances R e1 to R en . The resistance values of the temperature adjustment resistors R r1 to R rn can be set as appropriate depending on the type of storage cell, the rated capacity, and the like.

このような蓄電セル温度調整回路１４では、例えば、外気温が低い場合に蓄電装置１０に備えられた温度調整スイッチ（図示せず）を入れることによって、温度調整用抵抗Ｒr1〜Ｒrnを入状態となるように演算処理装置１８によって制御することができる。 In such a storage cell temperature adjustment circuit 14, for example, when a temperature adjustment switch (not shown) provided in the storage device 10 is turned on when the outside air temperature is low, the temperature adjustment resistors R r1 to R rn are turned on. It can control by the arithmetic processing unit 18 so that it may be in a state.

なお、キャパシタセルＣ1〜Ｃnが温度調整のために電力を消費しすぎることで、蓄電装置１０が使用できなくなることを防止するために、温度調整用スイッチＳr1〜Ｓrnが入状態の間、均等化ＩＣ１６のセル電圧検出回路によってキャパシタセルＣ1〜Ｃnの電圧値を測定し、所定の電圧値以下となった場合に、演算処理装置１８によって温度調整用スイッチＳr1〜Ｓrnを切状態とするように制御することもできる。 It should be noted that the temperature adjustment switches S r1 to S rn are turned on in order to prevent the capacitor cells C 1 to C n from consuming too much electric power for temperature adjustment, thereby making the power storage device 10 unusable. Meanwhile, when the voltage values of the capacitor cells C 1 to C n are measured by the cell voltage detection circuit of the equalization IC 16 and become equal to or lower than a predetermined voltage value, the temperature adjusting switches S r1 to S rn are calculated by the arithmetic processing unit 18. It is also possible to control so that is turned off.

この場合、キャパシタセルＣ1〜Ｃnの電圧値を個別に測定することによって、所定の電圧値以下となったキャパシタセルに対して並列に接続された温度調整用スイッチＳr1〜Ｓrnだけを切状態とすればよいので、蓄電装置１０全体を効率良く温度調整できるとともに、必要以上に蓄電装置１０の電力を消費しないようにすることができる。 In this case, by measuring the voltage values of the capacitor cells C 1 to C n individually, only the temperature adjustment switches S r1 to S rn connected in parallel to the capacitor cells having a predetermined voltage value or less are provided. Since the power storage device 10 may be turned off, the temperature of the entire power storage device 10 can be adjusted efficiently, and the power of the power storage device 10 can be prevented from being consumed more than necessary.
