Description

本発明は、スタータモータやその他の電装部品等、駆動のための電源電圧が異なる二つの系統の部品に対して適切な電圧を供給するための自動車用二電源装置に関する。   The present invention relates to a dual power supply device for an automobile for supplying an appropriate voltage to components of two systems having different power supply voltages for driving, such as a starter motor and other electrical components.

自動車用の電源電圧としては、乗用車用の１４Ｖ系と大型自動車用の２８Ｖ系の二つが主流となっている。通常は、自動車毎に電源電圧の統一化を図り、複雑な回路構成を回避しているが、製造コストの低減等のために様々な車種間での部品の共通化を目的として、一つの自動車で電源電圧が異なる二つの系統の部品を使用したいという要望がある。   There are two mainstream power supply voltages for automobiles: a 14V system for passenger cars and a 28V system for large automobiles. Normally, the power supply voltage is standardized for each vehicle to avoid complicated circuit configurations, but one vehicle is used for the purpose of sharing parts among various vehicle types in order to reduce manufacturing costs. There is a desire to use parts of two systems with different power supply voltages.

例えば、大型自動車において、電装部品には今まで通り電源電圧が２８Ｖ系のものを使用し、スタータモータには電源電圧が１４Ｖ系のものを使用する場合が想定される。この場合、２８Ｖ系の電源電圧から１４Ｖ系の電源電圧を作るために、ＤＣ−ＤＣコンバータを使用して２８Ｖ系の電源電圧を１４Ｖ系の電源電圧まで降圧すると共にバッテリ等の充放電器に充電し、この充放電器を１４Ｖ系の電源として使用することが考えられる。   For example, in a large automobile, a case where a power supply voltage of 28V system is used as an electrical component as before, and a starter motor having a power supply voltage of 14V system is assumed. In this case, in order to create a 14V system power supply voltage from the 28V system power supply voltage, a DC-DC converter is used to step down the 28V system power supply voltage to a 14V system power supply voltage and charge a charger / discharger such as a battery. However, it is conceivable to use this charger / discharger as a 14V power source.

しかしながら、電源電圧の降圧に使用されるＤＣ−ＤＣコンバータは、非常に高価であり、また複雑な電気電子装置であることから故障の確率も高く、製造コストやメンテナンスコストの増加等が問題となっている。   However, the DC-DC converter used for stepping down the power supply voltage is very expensive, and since it is a complicated electric and electronic device, there is a high probability of failure, and an increase in manufacturing cost and maintenance cost becomes a problem. ing.

そこで、本発明の目的は、ＤＣ−ＤＣコンバータを使用することなく、安価で故障し難い自動車用二電源装置を提供することにある。   Therefore, an object of the present invention is to provide an automotive dual power supply device that is inexpensive and hardly breaks down without using a DC-DC converter.

本発明に係る自動車用二電源装置を示す回路図である。It is a circuit diagram which shows the two power supply device for motor vehicles based on this invention. 図１の自動車用二電源装置の充電時の等価回路図である。It is an equivalent circuit diagram at the time of charge of the dual power supply device for automobiles of FIG. 図１の自動車用二電源装置の放電時の等価回路図である。FIG. 2 is an equivalent circuit diagram at the time of discharging of the automotive two power supply device of FIG. 1.

以下、本発明の好適な実施の形態を添付図面にしたがって説明する。   Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

図１に示すように、本実施の形態に係る自動車用二電源装置１００は、第１の電圧Ｖ1を供給する電源１０１と、第１の電圧Ｖ1を第２の電圧Ｖ2に降圧して供給する降圧回路１０２と、電源１０１と降圧回路１０２との間に接続された開閉器１０３と、を備える。 As shown in FIG. 1, the automotive dual power supply apparatus 100 according to the present embodiment includes a power supply 101 that supplies a first voltage V 1 and a step-down of the first voltage V 1 to a second voltage V 2. And a switch 103 connected between the power supply 101 and the step-down circuit 102.

ここで、第１の電圧Ｖ1は２８Ｖ系の電源電圧であり、第２の電圧Ｖ2は１４Ｖ系の電源電圧である。第２の電圧Ｖ2はスタータモータ１０４の電源電圧として使用され、第１の電圧Ｖ1はその他の電装部品（図示せず）の電源電圧として使用される。 Here, the first voltage V 1 is a 28V power supply voltage, and the second voltage V 2 is a 14V power supply voltage. Second voltage V 2 is used as a power supply voltage of the starter motor 104, the first voltages V 1 is used as a power supply voltage of the other electrical components (not shown).

電源１０１は、発電電圧が２８Ｖの発電機１０５に接続された鉛バッテリからなり、鉛バッテリには発電機１０５で発電された電気が充電される。ここでは、１４Ｖの電源電圧を供給する二つの鉛バッテリ１０６、１０７を直列接続することにより、２８Ｖの電源電圧を供給する１つの電源１０１を構成している。   The power source 101 is composed of a lead battery connected to a generator 105 having a power generation voltage of 28 V, and electricity generated by the generator 105 is charged in the lead battery. Here, one power supply 101 that supplies a power supply voltage of 28 V is configured by connecting two lead batteries 106 and 107 that supply a power supply voltage of 14 V in series.

降圧回路１０２は、複数の充放電器と、複数の充放電器の充電時に複数の充放電器が直列接続されると共に複数の充放電器の放電時に複数の充放電器が並列接続されるように配置された複数の整流素子と、を備える。   The step-down circuit 102 is configured such that a plurality of chargers / dischargers and a plurality of chargers / dischargers are connected in series when the plurality of chargers / dischargers are charged, and a plurality of chargers / dischargers are connected in parallel when the plurality of chargers / dischargers are discharged. And a plurality of rectifying elements arranged in the.

複数の充放電器は、第１の充放電器１０８と第２の充放電器１０９とからなり、複数の整流素子は、第１の整流素子１１０と第２の整流素子１１１と第３の整流素子１１２とからなる。   The plurality of chargers / dischargers are composed of a first charger / discharger 108 and a second charger / discharger 109, and the plurality of rectifier elements are a first rectifier element 110, a second rectifier element 111, and a third rectifier. An element 112 is included.

第１の充放電器１０８は、第１の端子１１３が開閉器１０３と第３の整流素子１１２のカソード１１４とに接続されると共に第２の端子１１５が第１の整流素子１１０のアノード１１６と第２の整流素子１１１のカソード１１７とに接続されている。   In the first charger / discharger 108, the first terminal 113 is connected to the switch 103 and the cathode 114 of the third rectifying element 112, and the second terminal 115 is connected to the anode 116 of the first rectifying element 110. The second rectifier element 111 is connected to the cathode 117.

第２の充放電器１０９は、第１の端子１１８が第１の整流素子１１０のカソード１１９と第３の整流素子１１２のアノード１２０とに接続されると共に第２の端子１２１が第２の整流素子１１１のアノード１２２に接続されている。より正確には、第２の充放電器１０９の第２の端子１２１と第２の整流素子１１１のアノード１２２は共に接地されて同電位となっている。   In the second charger / discharger 109, the first terminal 118 is connected to the cathode 119 of the first rectifier element 110 and the anode 120 of the third rectifier element 112, and the second terminal 121 is the second rectifier. It is connected to the anode 122 of the element 111. More precisely, the second terminal 121 of the second charger / discharger 109 and the anode 122 of the second rectifying element 111 are both grounded and at the same potential.

第１の充放電器１０８と第２の充放電器１０９は、電源１０１と同様に鉛バッテリからなっても良いが、キャパシタからなることがより好ましい。キャパシタは、安価で故障し難いため、自動車用二電源装置１００の部品として好適だからである。   Although the 1st charger / discharger 108 and the 2nd charger / discharger 109 may consist of a lead battery like the power supply 101, it is more preferable to consist of a capacitor. This is because the capacitor is suitable as a component of the dual power supply apparatus 100 for an automobile because it is inexpensive and hardly breaks down.

第１の整流素子１１０と第２の整流素子１１１と第３の整流素子１１２は、ショットキーバリアダイオードからなることが好ましい。ショットキーバリアダイオードは、電圧降下を低く抑えることができ、またスイッチング速度が速いことから、低損失で応答性の高い回路を実現することができるからである。   The first rectifying element 110, the second rectifying element 111, and the third rectifying element 112 are preferably made of Schottky barrier diodes. This is because the Schottky barrier diode can suppress a voltage drop to a low level and has a high switching speed, thereby realizing a circuit with low loss and high response.

開閉器１０３は、第１の充放電器１０８と第２の充放電器１０９の放電電圧が下限閾値以下であるとき、又はエンジンの始動に失敗したときに閉じられる。前者では、エンジンの始動に必要な電力を第１の充放電器１０８や第２の充放電器１０９に常に確保しておくことができる。また、後者では、エンジンの始動に失敗したとしても、事後的にエンジンの始動に必要な電力を第１の充放電器１０８や第２の充放電器１０９に確保することが可能となる。更に、両者を併用することも可能である。   The switch 103 is closed when the discharge voltage of the first charger / discharger 108 and the second charger / discharger 109 is equal to or lower than the lower threshold or when the engine fails to start. In the former, electric power necessary for starting the engine can always be secured in the first charger / discharger 109 or the second charger / discharger 109. In the latter case, even if the engine fails to start, it is possible to secure the power necessary for starting the engine in the first charger / discharger 109 and the second charger / discharger 109 later. Furthermore, it is also possible to use both together.

また、開閉器１０３は、第１の充放電器１０８と第２の充放電器１０９の放電電圧が上限閾値以上となったときに開かれる。これにより、第１の充放電器１０８と第２の充放電器１０９の過充電を防止することが可能となる。   The switch 103 is opened when the discharge voltages of the first charger / discharger 108 and the second charger / discharger 109 are equal to or higher than the upper threshold. As a result, overcharge of the first charger / discharger 108 and the second charger / discharger 109 can be prevented.

更に、開閉器１０３は、半導体スイッチからなることが好ましい。半導体スイッチは、可動部が無く故障し難いため、自動車用二電源装置１００の部品として好適だからである。   Furthermore, the switch 103 is preferably made of a semiconductor switch. This is because the semiconductor switch is suitable as a component of the dual power supply device 100 for an automobile because it has no movable part and is difficult to break down.

なお、自動車用二電源装置１００は、電源１０１と降圧回路１０２との間に接続された電圧安定化用整流素子１２３を更に備えることが好ましい。第１の充放電器１０８と第２の充放電器１０９は放電により電力を消費するため、降圧回路１０２に流れる電流は不安定である。この不安定な電流は、電源１０１や発電機１０５に悪影響を及ぼす虞がある。これに対して、電源１０１と降圧回路１０２との間に接続された電圧安定化用整流素子１２３を備えることにより、不安定な電流が電源１０１や発電機１０５に流れるのを防止することができ、電源１０１や発電機１０５への影響を排除することが可能となる。   The dual power supply apparatus 100 for an automobile preferably further includes a voltage stabilizing rectifier element 123 connected between the power supply 101 and the step-down circuit 102. Since the first charger / discharger 108 and the second charger / discharger 109 consume power by discharging, the current flowing through the step-down circuit 102 is unstable. This unstable current may adversely affect the power supply 101 and the generator 105. On the other hand, by providing the voltage stabilizing rectifier element 123 connected between the power source 101 and the step-down circuit 102, it is possible to prevent an unstable current from flowing to the power source 101 or the generator 105. Thus, it is possible to eliminate the influence on the power source 101 and the generator 105.

次に、自動車用二電源装置１００の作用を説明する。   Next, the operation of the dual power supply device 100 for an automobile will be described.

自動車用二電源装置１００では、開閉器１０３を開閉することにより、第１の充放電器１０８と第２の充放電器１０９の充放電状態を切り替えることができる。   In the dual power supply device 100 for an automobile, the charge / discharge state of the first charger / discharger 108 and the second charger / discharger 109 can be switched by opening / closing the switch 103.

具体的には、図２に示すように、第１の充放電器１０８と第２の充放電器１０９とを充電するためには、開閉器１０３を閉じて電源１０１と降圧回路１０２とを接続する。これにより、電源１０１と第１の充放電器１０８と第２の充放電器１０９とが直列接続されることになる。そうすると、電源１０１から第１の充放電器１０８と第２の充放電器１０９とに第１の電圧Ｖ1が供給され、第１の充放電器１０８と第２の充放電器１０９とが充電状態となる。 Specifically, as shown in FIG. 2, in order to charge the first charger / discharger 108 and the second charger / discharger 109, the switch 103 is closed and the power supply 101 and the step-down circuit 102 are connected. To do. As a result, the power source 101, the first charger / discharger 108, and the second charger / discharger 109 are connected in series. Then, the first voltage V 1 is supplied from the power source 101 to the first charger / discharger 108 and the second charger / discharger 109, and the first charger / discharger 108 and the second charger / discharger 109 are charged. It becomes a state.

また、図３に示すように、第１の充放電器１０８と第２の充放電器１０９とから第２の電圧Ｖ2を放電するためには、開閉器１０３を開いて電源１０１と降圧回路１０２とを短絡すると共に負荷であるスタータモータ１０４を降圧回路１０２に接続する。これにより、第１の充放電器１０８と第２の充放電器１０９とが並列接続されることになる。そうすると、第１の充放電器１０８と第２の充放電器１０９のそれぞれからスタータモータ１０４に第２の電圧Ｖ2が供給され、第１の充放電器１０８と第２の充放電器１０９とが放電状態となる。この場合、第１の充放電器１０８と第２の充放電器１０９は、第２の電圧Ｖ2を供給する二つの独立した並列電源として機能することになる。 Further, as shown in FIG. 3, in order to discharge the second voltage V 2 from the first charger / discharger 109 and the second charger / discharger 109, the switch 103 is opened and the power supply 101 and the step-down circuit are opened. The starter motor 104 which is a load is connected to the step-down circuit 102 while being short-circuited to 102. As a result, the first charger / discharger 108 and the second charger / discharger 109 are connected in parallel. Then, the second voltage V 2 is supplied from each of the first charger / discharger 108 and the second charger / discharger 109 to the starter motor 104, and the first charger / discharger 108, the second charger / discharger 109, Becomes a discharged state. In this case, the first charger / discharger 108 and the second charger / discharger 109 function as two independent parallel power supplies for supplying the second voltage V 2 .

これまで説明してきたように、本実施の形態に係る自動車用二電源装置１００では、安価で故障し難い第１の充放電器１０８、第２の充放電器１０９、第１の整流素子１１０、第２の整流素子１１１、及び第３の整流素子１１２を使用して降圧回路１０２を構成していることから、ＤＣ−ＤＣコンバータを使用して降圧回路１０２を構成する場合と比較して、製造コストを低減することができ、また耐故障性を向上させることが可能である。   As described so far, in the dual power supply device 100 for an automobile according to the present embodiment, the first charger / discharger 108, the second charger / discharger 109, the first rectifying element 110, which are inexpensive and difficult to break down, Since the step-down circuit 102 is configured by using the second rectifier element 111 and the third rectifier element 112, it is manufactured as compared with the case where the step-down circuit 102 is configured by using a DC-DC converter. Cost can be reduced and fault tolerance can be improved.

以上の通り、本発明によれば、ＤＣ−ＤＣコンバータを使用することなく、安価で故障し難い自動車用二電源装置１００を提供することができる。   As described above, according to the present invention, it is possible to provide an automotive dual power supply device 100 that is inexpensive and hardly breaks down without using a DC-DC converter.
