Description

本発明は、主発電機により発電された電力を船内負荷に給電する電源装置を備えた船舶に関し、そのうち特に自動車運搬船に適用されるものである。   The present invention relates to a ship equipped with a power supply device that supplies power generated by a main generator to an inboard load, and is particularly applicable to an automobile carrier.

従来、一般の船舶において電源装置は、ディーゼル機関を用いた複数台の主発電機と、同じくディーゼル機関を用いた１台の非常用発電機とを有して成り、通常時は、複数台の主発電機により船舶で使用される船内負荷に対する給電を行い、主発電機が故障する等の異常発生時には、非常用発電機に切り替えて船内負荷に対する給電を行うように構成されていた。   Conventionally, in a general ship, a power supply device has a plurality of main generators using a diesel engine and one emergency generator using the same diesel engine. Power is supplied to the ship load used on the ship by the main generator, and when an abnormality such as a failure of the main generator occurs, power is supplied to the ship load by switching to the emergency generator.

ところで、最近は船舶の大型化により、船舶の全負荷容量の増加に伴って主発電機も大型化しており、特に自動車を専門に運ぶ自動車運搬船（略してPCC（Pure Car Carrier）、PCTC(Pure
Car & Truck Carrier)）においては大型化の傾向が顕著である。このような船舶とその主発電機の大型化は、そのまま排ガスの増大につながるものであり、特に湾港内での排ガスの増大は重大な環境問題となっていた。 By the way, recently, due to the increase in size of ships, the main generator has also increased in size as the total load capacity of ships has increased.
In Car & Truck Carrier)), the trend toward larger size is remarkable. Such an increase in the size of the ship and its main generator directly leads to an increase in exhaust gas. In particular, an increase in exhaust gas in the bay port has become a serious environmental problem.

ここ最近の地球環境問題に対する関心の高まりに伴い、前述した船舶においても太陽光や風力等再生可能でクリーンなエネルギーの利用が注目されている。これらのエネルギーはクリーンではあるが、周囲の気象条件により発電量が変動するため、その活用にあたっては工夫が必要である。具体的な工夫としては、例えば特許文献１に開示されたものが一つの解決策を示している。   With the recent increase in interest in global environmental problems, the use of clean and renewable energy such as sunlight and wind power has been attracting attention in the aforementioned ships. Although these energies are clean, the amount of power generation varies depending on the surrounding weather conditions. As a specific device, for example, the one disclosed in Patent Document 1 shows one solution.

すなわち、主発電機により発電された電力が給電される船舶の主給電系統の下位に接続される複数の分電盤と、太陽電池の発電した電力を出力する太陽光発電装置を備え、複数の分電盤のうち特定の電力負荷が接続される特定の分電盤は、主発電機からの電力と太陽光発電装置からの電力が並列に接続されて供給されるように構成されている。ここで太陽電池の発電した電力は、その都度供給されて、通常電源の発電量を節約、補完するものであり、敢えて蓄電池を備えていない点に特徴がある。   That is, a plurality of distribution boards connected to the lower part of the main power supply system of a ship to which power generated by the main generator is supplied, and a solar power generation device that outputs the power generated by the solar cell, The specific distribution board to which a specific power load is connected among the distribution boards is configured such that the power from the main generator and the power from the solar power generation apparatus are connected in parallel and supplied. Here, the electric power generated by the solar cell is supplied each time to save and supplement the amount of power generated by the normal power source, and is characterized in that it does not have a storage battery.

特開２００２−３１５１９５号公報JP 2002-315195 A

しかしながら、前述した特許文献１に開示された従来の技術において、太陽電池による発電量は、気象条件の悪化等により十分な発電量が得られない場合も多く、気象条件に大きく左右されやすいものであり、必要時期に一定量の電力補完の確実性はないという問題があった。   However, in the conventional technique disclosed in Patent Document 1 described above, the amount of power generated by the solar cell is often not sufficient due to deterioration of weather conditions or the like, and is easily influenced by weather conditions. There was a problem that there was no certainty of a certain amount of power supplement at the required time.

かかる問題を解決すべく、太陽光により発電された電力を蓄電池に蓄え、必要な時にこれを取り出すように構成すれば、ある一定量の電力需要に対して確実に対応できるが、長期耐用の船舶用鉛蓄電池の場合には、大容量および大重量となるため、前述した特許文献１の段落０００８にも記載のとおり、無用のデッドカーゴ重量の増加につながるとして船舶への適用は敬遠されていた。   In order to solve this problem, it is possible to reliably respond to a certain amount of power demand by storing the power generated by sunlight in a storage battery and taking it out when necessary. In the case of a lead acid battery for use, since it has a large capacity and a large weight, as described in paragraph 0008 of Patent Document 1 described above, application to a ship has been avoided as it leads to an increase in the weight of dead dead cargo. .

本発明は、以上のような従来の技術が有する問題点並びに最近の大型自動車運搬船が安定性を確保するため船底部付近に固定バラストまたは海水バラストを搭載していることに着目してなされたものであり、蓄電池の利用により必要時期に一定量の電力補完を確実に行うことができると共に、その分だけ主発電機の運転停止による排出ガスの削減により環境負荷の低減を可能とし、さらに蓄電池の重量というマイナス面を逆に有効に活用することができる船舶を提供することを目的としている。   The present invention has been made by paying attention to the problems of the conventional technology as described above and the fact that a recent large-sized automobile carrier ship has a fixed ballast or seawater ballast mounted near the bottom of the ship to ensure stability. The use of a storage battery can ensure a certain amount of power supplementation at the required time, and can reduce the environmental load by reducing the exhaust gas by stopping the operation of the main generator. The object is to provide a ship that can effectively utilize the negative aspect of weight.

前記本発明は次のように作用する。
前記［１］に記載の船舶（１）によれば、電源装置（１０）によって、主発電機（１１）により発電された電力が船内負荷（１２）に給電され、主発電機（１１）により発電された電力のうち船内負荷（１２）を越えた分は蓄電池（１４）に充電される。そして、主発電機（１１）の運転停止時には、制御手段（１５）により、前記蓄電池（１４）の出力が主発電機（１１）に代わって船内負荷（１２）に給電される。 The present invention operates as follows.
According to the ship (1) described in [1], the power generated by the main generator (11) is supplied to the inboard load (12) by the power supply device (10), and the main generator (11) A part of the generated electric power exceeding the inboard load (12) is charged in the storage battery (14). When the operation of the main generator (11) is stopped, the output of the storage battery (14) is supplied to the inboard load (12) instead of the main generator (11) by the control means (15).

これにより、比較的小さな船内負荷（１２）に対しては、主発電機（１１）の運転を停止した状態でも、該主発電機（１１）に代わって蓄電池（１４）から給電することができる。すなわち、蓄電池（１４）の利用により、必要時期に一定量の電力補完を確実に行うことができる、   Thereby, even if the operation of the main generator (11) is stopped, a relatively small ship load (12) can be supplied with power from the storage battery (14) instead of the main generator (11). . That is, by using the storage battery (14), a certain amount of power supplementation can be reliably performed at a necessary time.

また、蓄電池（１４）の利用分だけ、主発電機（１１）の運転停止による排出ガスの削減となり、環境負荷を低減することが可能となる。しかも、蓄電池（１４）は船底に固定バラストとして配置されるので、船舶（１）のバランスを蓄電池（１４）の重量によって安定した状態に保つことができる。   Moreover, the amount of exhaust gas is reduced by the operation stop of the main generator (11) by the amount of use of the storage battery (14), and the environmental load can be reduced. And since a storage battery (14) is arrange | positioned as a fixed ballast at the ship's bottom, the balance of a ship (1) can be kept in the stable state with the weight of the storage battery (14).

前記［２］に記載の船舶（１）によれば、電源装置（１０）によって、航行時には主発電機（１１）により発電された電力のうち船内負荷（１２）を越えた分が蓄電池（１４）に充電される。一方、非航行時には、主発電機（１１）の運転を停止し、制御手段（１５）により蓄電池（１４）の出力が主発電機（１１）に代わって船内負荷（１２）に給電される。   According to the ship (1) described in the above [2], a part of the power generated by the main generator (11) during navigation by the power supply device (10) exceeds the inboard load (12) is stored in the storage battery (14). ) Is charged. On the other hand, at the time of non-navigation, the operation of the main generator (11) is stopped, and the output of the storage battery (14) is supplied to the inboard load (12) instead of the main generator (11) by the control means (15).

これにより、主発電機（１１）の稼働が当然必要な航行時においては、その余剰電力を蓄電池（１４）に効率良く充電することができる。一方、港湾内での着桟・荷役時等のように非航行時において、船内負荷（１２）が比較的小さな場合には、その必要な電力を蓄電池（１４）で賄うことが可能となるため、特に人的影響の大きな港湾内での環境に対して十分に配慮することができる。   Thereby, at the time of the navigation which the operation of the main generator (11) is naturally necessary, the surplus power can be efficiently charged to the storage battery (14). On the other hand, when the ship's load (12) is relatively small during non-navigation, such as when berthing or unloading in a harbor, the necessary power can be supplied by the storage battery (14). In particular, it is possible to pay sufficient attention to the environment in a harbor where human impact is significant.

前記［３］に記載の船舶（１）によれば、電源装置（１０）は、太陽光エネルギーにより発電する太陽電池（１７）をさらに有し、この太陽電池（１７）により発電された電力は、全て前記蓄電池（１４）に充電される。このように、クリーンなエネルギーを利用した余剰発電分を使って、前記蓄電池（１４）への充電を補完することができ、十分な蓄電池（１４）の出力を確保することで、非航行時においてより大きな船内負荷（１２）への対応も可能とし、さらには非常用発電機を省略することも可能となる。   According to the ship (1) described in [3], the power supply device (10) further includes a solar cell (17) that generates power using solar energy, and the power generated by the solar cell (17) is , All are charged in the storage battery (14). In this way, surplus power generation using clean energy can be used to supplement the charge to the storage battery (14), and by securing sufficient output of the storage battery (14) It is possible to cope with a larger inboard load (12), and it is also possible to omit an emergency generator.

前記［４］に記載の船舶（１）によれば、自動車運搬船に適用する。このような大型の船舶（１）においては、なおさら蓄電池（１４）が大型化しても、その重量増加というマイナス面を逆に有効に船底の固定バラストとして活用することができる。   According to the ship (1) described in [4], it is applied to an automobile carrier ship. In such a large vessel (1), even if the storage battery (14) is further increased in size, the negative aspect of its weight increase can be effectively used as a fixed ballast for the bottom of the vessel.

本発明に係る船舶によれば、電源装置は、主発電機により発電された電力のうち船内負荷を越えた分により充電される蓄電池と、主発電機の運転停止時に蓄電池の出力を主発電機に代わって給電する制御手段と、を有し、前記蓄電池を船底に固定バラストとして配置したから、蓄電池の利用により必要時期に一定量の電力補完を確実に行うことができると共に、その分だけ主発電機の運転停止による排出ガスの削減により環境負荷の低減を可能とし、さらに蓄電池の重量というマイナス面を逆に有効に活用することができる。   According to the ship according to the present invention, the power supply device includes a storage battery that is charged by the amount of power generated by the main generator that exceeds the load on the ship, and the output of the storage battery when the operation of the main generator is stopped. And the storage battery is arranged as a fixed ballast on the bottom of the ship, so that a certain amount of power can be reliably supplemented at a necessary time by using the storage battery, It is possible to reduce the environmental load by reducing the exhaust gas by stopping the operation of the generator, and to effectively use the negative aspect of the weight of the storage battery.

以下、図面に基づき本発明を代表する実施の形態を説明する。
図１は、本実施の形態に係る船舶１に装備される電源装置１０の概略構成を示すブロック図である。図２は、船舶１を模式的に示した側面図であり、図３は、同じく船舶１を模式的に示した背面図である。以下に、船舶１を自動車運搬船に適用した場合を例に説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments representing the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a power supply device 10 equipped in a ship 1 according to the present embodiment. FIG. 2 is a side view schematically showing the ship 1, and FIG. 3 is a rear view schematically showing the ship 1. Below, the case where the ship 1 is applied to a motor vehicle carrier is demonstrated to an example.

船舶１である自動車運搬船は、輸出入する自動車を専門に運搬する構造を有した船であり、その船型は一般の船舶とは大きく異なり、図２、図３に示すように、船倉部分は大量の自動車を搭載できるように縦長のずんぐりとした船型となっている。造船業界では、略してPCC（Pure Car Carrier）またはPCTC(Pure Car & Truck Carrier)と言う。   The car carrier, which is the ship 1, is a ship that has a structure that specially carries automobiles to be imported and exported, and its ship type is significantly different from that of ordinary ships. As shown in FIGS. It is a long and stubborn hull so that it can be equipped with any car. In the shipbuilding industry, it is called PCC (Pure Car Carrier) or PCTC (Pure Car & Truck Carrier) for short.

図１に示すように、本実施の形態に係る船舶１の電源装置１０は、主発電機１１により発電された電力のうち船内負荷１２を越えた分を充電機器１３を介して充電する蓄電池１４と、主発電機１１の運転停止時に蓄電池１４の出力を主発電機１１に代わって給電する充電制御器（制御手段）１５等を有して成る。なお、電源装置１０は、船内の適所に設置されている。   As shown in FIG. 1, the power supply device 10 of the ship 1 according to the present embodiment charges a storage battery 14 that charges a portion of the power generated by the main generator 11 that exceeds the inboard load 12 via a charging device 13. And a charging controller (control means) 15 for supplying the output of the storage battery 14 instead of the main generator 11 when the operation of the main generator 11 is stopped. The power supply device 10 is installed at an appropriate place on the ship.

主発電機１１は、具体的にはディーゼル発電機であり、ディーゼルエンジンで発電機を回して発電させ、その電力を制御して、船内負荷１２に給電するものである。船内負荷１２は、図示省略した配電盤により、使途別に分けられて、それぞれ必要な電力が給電される。   Specifically, the main generator 11 is a diesel generator, which generates power by rotating the generator with a diesel engine, controls the electric power, and supplies power to the inboard load 12. The inboard load 12 is divided according to usage by a switchboard (not shown) and is supplied with necessary power.

充電機器１３は、主発電機１１により発電された電力のうち船内負荷１２を越えた分を蓄電池１４に充電させるものである。蓄電池１４は、一般に広く利用されている鉛蓄電池でも良いが、長期耐用の船舶用鉛蓄電池の場合は、大容量および大重量となる。もちろん鉛蓄電池に限られるものではなく、蓄電池は近年自動車産業と結びつき、リチウムイオン電池等の二次電池の急速な技術革新により、蓄電システムの高機能化、軽量化、低価格化が進んでいる。かかる技術環境を踏まえ、全く新しい蓄電池を活用しても良い。   The charging device 13 charges the storage battery 14 with the amount of power generated by the main generator 11 that exceeds the inboard load 12. The storage battery 14 may be a lead storage battery that is widely used in general. However, in the case of a marine lead storage battery having a long-term durability, the storage battery 14 has a large capacity and a large weight. Of course, the battery is not limited to lead-acid batteries. In recent years, storage batteries have been linked to the automobile industry, and rapid technological innovations in secondary batteries such as lithium-ion batteries have led to higher functionality, lighter weight, and lower prices for power storage systems. . In light of this technical environment, a completely new storage battery may be used.

ここで蓄電池１４は、図２および図３に示すように、船底付近に固定バラストとして配置されている。本実施の形態に係る蓄電池１４は、船底におけるほぼ中央の中心線付近に配置されているが、例えば図４に示すように、船底のほぼ中央の左右両側に一対に分けて配置するようにしても良い。なお、船底には図示省略したが、固定バラストを成す蓄電池１４とは別に、必要に応じてバラスト水（海水）を注入するタンクが配置されている。   Here, as shown in FIGS. 2 and 3, the storage battery 14 is disposed as a fixed ballast near the ship bottom. The storage battery 14 according to the present embodiment is disposed in the vicinity of the center line at the center of the ship bottom. For example, as shown in FIG. Also good. Although not shown in the figure, a tank for injecting ballast water (seawater) as necessary is disposed separately from the storage battery 14 forming the fixed ballast.

充電制御器１５は、蓄電池１４の充電状況を監視し過剰な放電を防止するための制御手段であり、蓄電池１４の出力は充電制御器１５によりコントロールされながら、主発電機１１に代わって船内負荷１２に給電される。また、インバータ１６は、蓄電池１４より充電制御器１５を介して出力される直流電力を交流電力に変換するものである。なお、電源装置１０には、蓄電池１４を備えたことにより、非常用発電機は装備されていないが、万一の故障等に備えて非常用発電機も別途装備しても良い。   The charging controller 15 is a control means for monitoring the charging state of the storage battery 14 and preventing excessive discharge. The output of the storage battery 14 is controlled by the charging controller 15 while the load on the ship in place of the main generator 11. 12 is fed. The inverter 16 converts DC power output from the storage battery 14 via the charging controller 15 into AC power. In addition, although the power generator 10 is equipped with the storage battery 14, it is not equipped with an emergency generator, but may be equipped with an emergency generator separately in case of a failure.

また、電源装置１０は、太陽光エネルギーにより発電する太陽電池１７をさらに有している。太陽電池１７は、前記充電制御器１５を介して蓄電池１４に接続されており、充電制御器１５の制御によって、太陽電池１７により発電された電力は蓄電池１４に充電されるように設定されている。図示省略したが太陽電池１７の主要部である平面パネルは、図２に示す船舶１の上甲板上に設置される。   In addition, the power supply device 10 further includes a solar cell 17 that generates power using solar energy. The solar battery 17 is connected to the storage battery 14 via the charge controller 15, and the power generated by the solar battery 17 is set to be charged in the storage battery 14 by the control of the charge controller 15. . Although not shown, the flat panel, which is the main part of the solar cell 17, is installed on the upper deck of the ship 1 shown in FIG.

次に、船舶１の作用について説明する。
本実施の形態に係る船舶１によれば、電源装置１０によって、主発電機１１により発電された電力が船内負荷１２に給電され、主発電機１１により発電された電力のうち船内負荷１２を越えた分は蓄電池１４に充電される。そして、主発電機１１の運転停止時には、充電制御器１５による制御の下、前記蓄電池１４の出力が主発電機１１に代わって船内負荷１２に給電される。 Next, the operation of the ship 1 will be described.
According to the ship 1 according to the present embodiment, the power generated by the main generator 11 is supplied to the inboard load 12 by the power supply device 10 and exceeds the inboard load 12 of the electric power generated by the main generator 11. The storage battery 14 is charged for the remaining portion. When the operation of the main generator 11 is stopped, the output of the storage battery 14 is supplied to the inboard load 12 in place of the main generator 11 under the control of the charging controller 15.

これにより、比較的小さな船内負荷１２に対しては、主発電機１１の運転を停止した状態でも、該主発電機１１に代わって蓄電池１４から給電することができる。すなわち、蓄電池１４の利用により、必要時期に一定量の電力補完を確実に行うことができる。また、その分だけ主発電機１１の運転停止による排出ガスの削減となり、環境負荷を低減することが可能となる。   As a result, even a relatively small inboard load 12 can be supplied with power from the storage battery 14 instead of the main generator 11 even when the operation of the main generator 11 is stopped. That is, by using the storage battery 14, a certain amount of power supplement can be reliably performed at a necessary time. Further, the exhaust gas is reduced by the operation stop of the main generator 11, and the environmental load can be reduced.

しかも、図２および図３に示すように、蓄電池１４は船底に固定バラストとして配置される。これにより、蓄電池１４は、船舶１の安定性向上に積極的に利用されることになる。   Moreover, as shown in FIGS. 2 and 3, the storage battery 14 is arranged as a fixed ballast on the bottom of the ship. As a result, the storage battery 14 is actively used to improve the stability of the ship 1.

このような船舶１によれば、湾港内における着桟・荷役時等の非航行時に、主発電機１１を使用せずに運転を停止し、蓄電池１４に溜めた電力により船内負荷１２の必要電力を賄う。ここでの必要電力は、船内の照明や換気等に関わる負荷であるが、蓄電池１４の出力が主発電機１１に代わって船内負荷１２に給電されるため、いわゆる陸電供給を行わなくてもゼロエミッションが実現され、環境に優しいシステムが提供できる。   According to such a ship 1, the operation is stopped without using the main generator 11 during non-navigation such as when berthing or cargo handling is performed in the bay port, and the required power of the inboard load 12 by the power stored in the storage battery 14. To cover. The necessary power here is a load related to inboard lighting, ventilation, etc., but since the output of the storage battery 14 is supplied to the inboard load 12 instead of the main generator 11, so-called land power supply is not performed. Zero emission is realized and an environmentally friendly system can be provided.

一方、非航行時の必要電力量に見合う容量を有する蓄電池１４には、航海中等の航行時に主発電機１１により発電された電力のうち船内負荷１２を越えた分が充電される。要するに、主発電機１１の発電量のうち、船内負荷１２への給電分の他、少なくとも一部を蓄電池１４の充電に供給すれば足りる。   On the other hand, the storage battery 14 having a capacity commensurate with the required power amount during non-navigation is charged with the power exceeding the inboard load 12 among the electric power generated by the main generator 11 during navigation such as during voyage. In short, it is only necessary to supply at least a part of the power generation amount of the main generator 11 to the storage battery 14 in addition to the power supplied to the inboard load 12.

さらに、電源装置１０は、太陽光エネルギーにより発電する太陽電池１７を有しており、航海中に太陽電池１７により発電された電力は、全て蓄電池１４に充電される。このように、クリーンなエネルギーを利用した余剰発電分を使って、前記蓄電池１４への充電を補完することができ、十分な蓄電池１４の出力を確保することで、非航行時においてより大きな船内負荷への対応も可能となり、さらには非常用発電機を省略することも可能となる。   Furthermore, the power supply device 10 has a solar cell 17 that generates power by using solar energy, and all the electric power generated by the solar cell 17 during the voyage is charged to the storage battery 14. In this way, surplus power generation using clean energy can be used to supplement the charging of the storage battery 14, and by securing a sufficient output of the storage battery 14, a larger inboard load during non-voyage It is also possible to eliminate the emergency generator.

特に、船舶１を適用した自動車運搬船は、大型で広い上甲板を有しているため、太陽電池１７の主要部である平面パネルの設置面積を十分に確保することが可能となり、なおさら太陽電池１７による十分な発電量を獲得することができる。ここで蓄電池１４が大型化しても、その重量増加というマイナス面を逆に有効に船底の固定バラストとして活用することができる。   In particular, since the automobile carrier ship to which the ship 1 is applied has a large and wide upper deck, it is possible to sufficiently secure the installation area of the flat panel which is the main part of the solar cell 17, and even more, the solar cell 17. A sufficient amount of power can be obtained. Here, even if the storage battery 14 is increased in size, the negative aspect of its weight increase can be effectively utilized as a fixed ballast for the ship bottom.

次に、最近の大型自動車運搬船を例に採り、定量的な説明を加える。
船舶１の上甲板上における太陽電池１７の平面パネルの設置面積を約３３３０m2と想定すると、太陽光による年間発電期待量は約３９万kWh／年（低緯度航行の場合は約４７万 kWh／年）となり、航海日数１０日では約１．１〜１．３万kWh、２０日では２．１〜２．６万kWhとなる。 Next, taking a recent large automobile carrier as an example, a quantitative explanation is added.
Assuming about 3330M 2 footprint of the flat panel solar cell 17 on the upper deck of the ship 1, annual energy expected amount of sunlight in the case of about 390,000 kWh / year (low latitudes sailing about 470,000 kWh / Year), it will be about 1.1 to 13,000 kWh on 10 days of voyage and 2.1 to 26,000 kWh on 20th.

非航行時である着桟・係留・荷役時の必要電力量を、所定の電力表に基づき約３３１２０kWhと想定すると、航海日数１０日で必要電力量の約１／３を、航海日数２０日で必要電力量の約２／３を太陽電池１７による太陽光発電でカバーすることが可能である。なお、太陽電池１７の発電電力が不足したとしても、主発電機１１からの給電によって蓄電池１４には蓄電される。   Assuming that the required power consumption during non-voyage, docking, mooring, and cargo handling is approximately 33120kWh based on the prescribed power table, approximately 1/3 of the required power consumption is 10 days in voyage and 20 days in voyage. About 2/3 of the required electric energy can be covered by solar power generation by the solar battery 17. Even if the generated power of the solar battery 17 is insufficient, the storage battery 14 is charged by the power supply from the main generator 11.

蓄電池１４の容量は、現状の鉛蓄電池の性能をベースとすれば９２０００kWhとなるが、リチウムイオン電池の最近の目標性能をベースにすれば４１０００kWhとなり、さらに改善が期待される。太陽光発電にプラスして、航海時における主発電機１１で補完して蓄電池１４に蓄電することにより、前記航海時における必要電力量を確保することができる。   The capacity of the storage battery 14 is 92000 kWh based on the performance of the current lead storage battery, but is 41000 kWh based on the recent target performance of the lithium ion battery, and further improvement is expected. In addition to the photovoltaic power generation, the required amount of power during the voyage can be ensured by supplementing with the main generator 11 during the voyage and storing in the storage battery 14.

以上、本発明の実施の形態を図面によって説明してきたが、具体的な構成はこれらの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。例えば、前記電源装置１０では太陽電池１７を備えているが、太陽電池１７を省いて構成しても良い。   As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the present invention can be modified or added without departing from the scope of the present invention. Included in the invention. For example, although the power supply device 10 includes the solar battery 17, the solar battery 17 may be omitted.

本発明に係る船舶は、特に大型の自動車運搬船に適用することができる。   The ship according to the present invention can be applied particularly to a large automobile carrier ship.
