An electric equipment storage box equipped with a branch breaker is installed on the primary side of the vehicle charging device, and current is sent to the vehicle charging device via the branch breaker.

The battery is charged at 80% or less of the rated current (see Patent Document 1).

しかしながら、ブレーカの定格電流から大幅に低い電流を車両へ供給するものとなるため、車両の充電時間が長くなってしまうという問題がある。 However, since a current significantly lower than the rated current of the breaker is supplied to the vehicle, there is a problem that the vehicle charging time becomes long.

以下に発明を実施するための形態を示す。本実施形態の車両用充電システム１は、一次側に接続されたブレーカ２１に設定される定格電流値未満の電流を車両８に供給する車両用充電装置３を備えている。また、この車両用充電システム１の車両用充電装置３の一次側に接続されたブレーカ２１は、バイメタルを使用した引き外し機構を備えたブレーカである。そして、車両用充電装置３は、前記ブレーカ２１の定格電流値を車両用充電装置３に入力可能な設定手段３３と、「設定手段３３により入力されたブレーカ２１の定格電流値から、車両用充電装置３自身が使用するとされた使用電流値を差し引いた値」、若しくは、「設定手段３３により入力されたブレーカ２１の定格電流値から、車両用充電装置３自身が使用するとされた使用電流値及び所定の電流値を差し引いた値」、を演算可能な演算手段３２と、を備えている。更には、この演算手段３２で得られた前記値を用いて車両８に給電する給電電流値を定めるものである。このため、ブレーカ２１の定格電流に近い電流値を車両８に供給するためのシステムを提供することが可能となる。なお、車両用充電装置３は、演算手段３２からの指示に従って、給電手段３１から給電電流分、車両８に給電可能となる。 Modes for carrying out the invention will be shown below. The vehicle charging system 1 of the present embodiment includes the vehicle charging device 3 that supplies the vehicle 8 with a current that is less than the rated current value set in the breaker 21 connected to the primary side. Further, the breaker 21 connected to the primary side of the vehicle charging device 3 of the vehicle charging system 1 is a breaker including a tripping mechanism using bimetal. Then, the vehicle charging device 3 charges the vehicle from the setting means 33 capable of inputting the rated current value of the breaker 21 to the vehicle charging device 3 and “the rated current value of the breaker 21 input by the setting means 33. The value obtained by subtracting the value of the current used by the device 3 itself, or the value of the rated current of the breaker 21 input by the setting means 33, and the value of the current used by the vehicle charging device 3 itself and And a calculation means 32 capable of calculating "a value obtained by subtracting a predetermined current value". Furthermore, the value of the power supply current for supplying power to the vehicle 8 is determined using the value obtained by the calculation means 32. Therefore, it is possible to provide a system for supplying the vehicle 8 with a current value close to the rated current of the breaker 21. The vehicle charging device 3 can supply power to the vehicle 8 from the power supply unit 31 according to the power supply current according to the instruction from the calculation unit 32.

ここで、ブレーカについて、説明する。ブレーカ２１は通常、分電盤などの電気機器収納用箱２に収められている。ブレーカ２１には、主として、熱動式ブレーカと、完全電磁式ブレーカ、電子式ブレーカがあることが知られている。 Here, the breaker will be described. The breaker 21 is usually housed in a box 2 for storing electrical equipment such as a distribution board. It is known that the breaker 21 mainly includes a thermal breaker, a complete electromagnetic breaker, and an electronic breaker.

熱動式ブレーカは、バイメタルを使用した引き外し機構を備えるものであるため、周囲温度の影響を受け、定格電流値が変動してしまう。このため、周囲温度を考慮して定格電流値より余裕を持った電流を流す必要がある。その一方で、完全電磁式ブレーカと電子式ブレーカは、引き外し機構にバイメタルを用いていないものであるため、周囲温度が変化しても定格電流値が変化しにくいため、周囲温度を考慮する必要がなく、定格電流値に近い電流値を流すことができる。つまり、引き外し機構にバイメタルを用いていないブレーカの典型例は、完全電磁式ブレーカ及び電子式ブレーカであり、熱動式ブレーカは引き外し機構にバイメタルを用いたブレーカである。また、熱動式ブレーカの他にも、バイメタルを使用した引き外し機構を備えたものは存在するが、当然ながら、そのようなものは引き外し機構にバイメタルを用いていないブレーカでは無い。 Since the thermal breaker is equipped with a tripping mechanism using bimetal, the rated current value fluctuates under the influence of ambient temperature. Therefore, in consideration of the ambient temperature, it is necessary to flow a current with a margin larger than the rated current value. On the other hand, since the complete electromagnetic breaker and electronic breaker do not use bimetal for the trip mechanism, the rated current value does not change easily even if the ambient temperature changes, so it is necessary to consider the ambient temperature. It is possible to flow a current value close to the rated current value. That is, typical examples of breakers that do not use bimetal for the trip mechanism are fully electromagnetic breakers and electronic breakers, and the thermal breaker is a breaker that uses bimetal for the trip mechanism. Further, in addition to the thermal breaker, there are those equipped with a tripping mechanism using bimetal, but of course, such a breaker does not use bimetal for the tripping mechanism.

本発明では、完全電磁式ブレーカと電子式ブレーカのような周囲温度の影響を受けにくいブレーカを車両用充電装置３の一次側に接続することで、周囲温度の影響を抑制し、制御しなくてはならない電流値を安定させ、ブレーカ２１の定格電流値に近い電流値を車両用充電装置３に流すことができるようにしている。 In the present invention, by connecting a breaker such as a complete electromagnetic breaker and an electronic breaker that is not easily affected by the ambient temperature to the primary side of the vehicle charging device 3, the influence of the ambient temperature is suppressed and control is not required. The current value that does not occur is stabilized, and a current value close to the rated current value of the breaker 21 can be supplied to the vehicle charging device 3.

ここで車両用充電システム１について説明する。図１及び図２に示されていることから理解されるように、電気自動車やプラグインハイブリッドカーなどの電動車両８を充電するための車両用充電装置３は、一次側がブレーカ２１に接続され、ブレーカ２１を介して供給された電流を二次側に接続された車両８へ給電する。ブレーカ２１の定格電流を超える電流値を流してしまうと、ブレーカ２１が遮断してしまうため、車両用充電装置３は、ブレーカ２１の定格電流未満の電流を車両８へ供給するが、本発明では、車両用充電装置３自身が使用するとされた使用電流値についても考慮して車両８へ供給する電流値を決定する。 Here, the vehicle charging system 1 will be described. As is understood from what is shown in FIGS. 1 and 2, a vehicle charging device 3 for charging an electric vehicle 8 such as an electric vehicle or a plug-in hybrid car has a primary side connected to a breaker 21. The electric current supplied through the breaker 21 is supplied to the vehicle 8 connected to the secondary side. If a current value exceeding the rated current of the breaker 21 flows, the breaker 21 shuts off. Therefore, the vehicle charging device 3 supplies the vehicle 8 with a current less than the rated current of the breaker 21. The current value supplied to the vehicle 8 is determined in consideration of the current value used by the vehicle charging device 3 itself.

なお、車両用充電装置３自身が使用するとされた使用電流値とは、車両用充電装置３に搭載される内部機器３９が使用するとされた電流値のことである。例えば、車両用充電装置３に搭載された液晶ディスプレイや、車両用充電装置３が外部機器と通信するための通信装置といった電気電子機器３８が使用すると考えられる電流値の他に給電手段３１、演算手段３２、設定手段３３、測定手段３４などが使用すると考えらえる電流値を加えた電流値である。 The current value used by the vehicle charging device 3 itself is the current value used by the internal device 39 mounted in the vehicle charging device 3. For example, in addition to the current value that is considered to be used by the electric/electronic device 38 such as a liquid crystal display mounted on the vehicle charging device 3 or a communication device for the vehicle charging device 3 to communicate with an external device, the power supply unit 31, the calculation. It is a current value to which the current values considered to be used by the means 32, the setting means 33, the measuring means 34, etc. are added.

車両用充電装置３に搭載される内部機器３９が使用するとされる電流値は、内部機器３９毎に定められているため、車両用充電装置３に搭載される内部機器３９が使用するとされる電流値の最大値を合計したものを使用電流値とし、設定手段３３により車両用充電装置３に入力することで、固定値として設定するものとしてもよい。このように、設定手段３３が、車両用充電装置３自身が使用するとされた使用電流値を車両用充電装置３に入力可能であるものとすることで、所望の値に使用電流値を定めることができ、使用環境にあわせやすくなる。なお、図３には、この場合の各電流値の経時変化の例が示されているが、内部機器３９が実際に使用した電流値に関わらず、各電流値に変動が無いことを表している。 Since the current value used by the internal device 39 mounted on the vehicle charging device 3 is determined for each internal device 39, the current value used by the internal device 39 mounted on the vehicle charging device 3 is determined. The sum of the maximum values may be used as the current value to be input to the vehicle charging device 3 by the setting means 33 to set it as a fixed value. In this way, the setting means 33 determines the use current value to a desired value by allowing the use current value that the vehicle charger 3 itself uses to be input to the vehicle charger 3. This makes it easier to match the usage environment. It should be noted that FIG. 3 shows an example of the change over time of each current value in this case, but shows that there is no change in each current value regardless of the current value actually used by the internal device 39. There is.

設定手段３３による使用電流値の設定は、車両用充電装置３の製造の段階で行ってもよいし、車両用充電装置３が設置された後に行われるものであってもよい。また、実施形態では、使用電流値は一度設定した後でも変更可能である。なお、車両用充電装置３に搭載される内部機器３９が使用する電流値の最大値を合計したものを使用電流値とした場合、実際に車両用充電装置３が使用する電流値は、使用電流値以下となることが多いため、ブレーカ２１の定格電流値を超える電流が流れることを防ぐことができ、ブレーカ２１の不要な遮断を防ぐことができる。 The setting of the used current value by the setting means 33 may be performed at the stage of manufacturing the vehicle charging device 3, or may be performed after the vehicle charging device 3 is installed. Further, in the embodiment, the used current value can be changed even after being set once. When the sum of the maximum values of the current values used by the internal device 39 mounted on the vehicle charging device 3 is set as the used current value, the current value actually used by the vehicle charging device 3 is the used current. Since it is often less than the value, it is possible to prevent a current exceeding the rated current value of the breaker 21 from flowing, and it is possible to prevent unnecessary breakage of the breaker 21.

ところで、内部機器３９が実際に使用する電流値は、使用状況に応じて変動する。そのため、車両用充電装置３に搭載される内部機器３９が使用する電流値を測定手段３４で測定した結果を使用電流値として用いてもよい。この場合、測定手段３４によって使用電流値が測定される度に演算手段３２によって、給電電流値が演算され、演算された給電電流値を車両８に給電できる電流値とする。つまり、変動する給電電流値の測定結果を反映させて車両８への給電を制御する。そうすることで、測定手段３４による測定結果から得られる使用電流値に追従して給電電流値が決定されるため、より多くの電流を車両８へ給電することができ、充電時間を短縮することができる。なお、図４には、この場合の各電流値の経時変化の例が示されている。 By the way, the current value actually used by the internal device 39 varies depending on the usage situation. Therefore, the result of measuring the current value used by the internal device 39 mounted on the vehicle charging device 3 by the measuring means 34 may be used as the used current value. In this case, the feeding current value is calculated by the calculating unit 32 every time the use current value is measured by the measuring unit 34, and the calculated feeding current value is set as the current value capable of feeding the vehicle 8. That is, the power supply to the vehicle 8 is controlled by reflecting the measurement result of the fluctuating power supply current value. By doing so, the power supply current value is determined following the used current value obtained from the measurement result by the measuring means 34, so that more current can be supplied to the vehicle 8 and the charging time can be shortened. You can It should be noted that FIG. 4 shows an example of a change with time of each current value in this case.

このようなことを可能とするため、車両用充電システム１は、車両用充電装置３自身が使用した電流値を測定する測定手段３４を備えるものとし、前記測定手段３４で測定された電流値を車両用充電装置３が使用するとされた使用電流値とし、演算手段３２は、使用電流値とされる電流値を測定手段３４が測定する度に給電電流値を定める値を演算するように構成することが好ましい。 In order to enable such a thing, the vehicle charging system 1 is provided with a measuring unit 34 for measuring the current value used by the vehicle charging apparatus 3 itself, and the current value measured by the measuring unit 34 is The calculation means 32 is configured to calculate a value that determines the power supply current value each time the measurement means 34 measures the current value that is the use current value, which is the use current value that is used by the vehicle charging device 3. It is preferable.

なお、図３及び図４に示す例では、「設定手段３３により入力されたブレーカ２１の定格電流値から、車両用充電装置３自身が使用するとされた使用電流値を差し引いた値」を給電電流値としているが、ブレーカ２１の不要な遮断を回避するためにさらに裕度を設け、「設定手段３３により入力されたブレーカ２１の定格電流値から、車両用充電装置３自身が使用するとされた使用電流値及び所定の電流値を差し引いた値」を給電電流値としても良い。 In the examples shown in FIGS. 3 and 4, the “feeding current is a value obtained by subtracting the used current value used by the vehicle charging device 3 itself from the rated current value of the breaker 21 input by the setting means 33”. Although the value is used as a value, a further allowance is provided in order to avoid unnecessary interruption of the breaker 21, and "the charging current for the vehicle 3 itself is determined to be used from the rated current value of the breaker 21 input by the setting means 33. The value obtained by subtracting the current value and the predetermined current value" may be used as the power supply current value.

ところで、車両用充電装置から車両８へ供給する電流値を高くする方法としては、ブレーカの定格電流値を高くするという方法がある。例えば、ブレーカの定格電流値の８０％を給電電流値とする場合、「ブレーカの定格電流値：３０Ａ⇒給電電流値：２４Ａ」だったものを、「ブレーカの定格電流値：４０Ａ⇒給電電流値：３２Ａ」とすることで、給電電流値を高くすることができる。 By the way, as a method of increasing the current value supplied from the vehicle charging device to the vehicle 8, there is a method of increasing the rated current value of the breaker. For example, when 80% of the rated current value of the breaker is set as the power supply current value, the value of "breaker rated current value: 30A ⇒ power supply current value: 24A" is changed to "breaker rated current value: 40A ⇒ power supply current value : 32 A”, the power supply current value can be increased.

しかしながら、ブレーカの定格電流値毎にブレーカの二次側に接続する電線サイズ（つまり、ブレーカから車両用充電装置までの電線サイズ）は定められており、ブレーカの定格電流値を高くすることで、電線サイズも大きくする必要がある。したがって、既設の車両用充電システムに設けられたブレーカを、該ブレーカよりも定格電流値が高いブレーカに変更する場合には、ブレーカと車両用充電装置の間の電線の配線をやり直す必要が出てしまう。一方、既設の車両用充電システムについて、本発明のように構成し直す場合、ブレーカの定格電流値を高くする必要が無いため、既設の車両用充電装置とブレーカ間に使用されている電線のサイズを変更することなく、車両用充電装置から車両８への給電電流値を高くすることができるという利点がある。 However, the wire size (that is, the wire size from the breaker to the vehicle charging device) to be connected to the secondary side of the breaker is set for each rated current value of the breaker, and by increasing the rated current value of the breaker, It is also necessary to increase the wire size. Therefore, when changing the breaker provided in the existing vehicle charging system to a breaker with a higher rated current value than the breaker, it is necessary to rewire the electric wire between the breaker and the vehicle charging device. I will end up. On the other hand, if the existing vehicle charging system is reconfigured as in the present invention, it is not necessary to increase the rated current value of the breaker, so the size of the electric wire used between the existing vehicle charging device and the breaker. There is an advantage that the value of the power supply current from the vehicle charging device to the vehicle 8 can be increased without changing the above.

以上、実施形態を例に挙げて本発明について説明してきたが、本発明は上記実施形態に限定されることはなく、各種の態様とすることが可能である。 Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above-described embodiment, and various modes are possible.
