Description

バッテリ装置、バッテリ及び移動体Battery device, battery and moving body
　本発明は、バッテリ装置及びバッテリと、これらのバッテリ装置やバッテリを搭載した電動車両を含む移動体に関する。 The present invention relates to a battery device, a battery, and a movable body including the battery device and an electric vehicle equipped with the battery.
　電動車両やパーソナルコンピュータ、その他デジタル機器などには二次電池であるバッテリを搭載し、このバッテリからモータや制御部等に対して電力を供給しているものがある。これら電動車両やデジタル機器といったアプリケーションに搭載されたバッテリは一般家庭やオフィス等の商用電源で充電が可能である。 Some electric vehicles, personal computers, and other digital devices are equipped with a battery, which is a secondary battery, and supplies power to the motor, control unit, and the like from this battery. A battery mounted in an application such as an electric vehicle or a digital device can be charged by a commercial power source such as a general home or office.
　バッテリの充電器としては、例えば標準充電器と急速充電器とを備える場合がある。標準充電器は比較的小さい電流で充電を行うので、満充電までの時間が比較的長い。一方、急速充電器は比較的大きい電流で充電するので、標準充電器より短い時間でバッテリを満充電の状態にすることが可能である。このような標準充電器と急速充電器とを使用可能なバッテリの一例を特許文献１に見ることができる。特許文献１に記載された電池パック（バッテリ）は通常（標準）充電用端子部と急速充電用端子部との２箇所の端子部を備え、標準充電と急速充電とが可能になっている。 As a battery charger, for example, a standard charger and a quick charger may be provided. Since the standard charger charges with a relatively small current, the time to full charge is relatively long. On the other hand, since the quick charger is charged with a relatively large current, the battery can be fully charged in a shorter time than the standard charger. An example of a battery that can use such a standard charger and a quick charger can be found in Patent Document 1. The battery pack (battery) described in Patent Document 1 includes two terminal portions, ie, a normal (standard) charging terminal portion and a quick charging terminal portion, and can perform standard charging and quick charging.
特開２００９－１８１８８８号公報JP 2009-181888 A
　ここで、バッテリとそのバッテリに対して充放電を行う接続器（例えば充電器）とを備えるバッテリ装置にはバッテリの充放電を制御するための制御部を有するものがある。バッテリと接続器との各々の制御部の間では、バッテリの電力やその充放電に関する様々な情報、例えばバッテリの電圧や残容量といった情報について通信を行うことで、適正な充放電が遂行できるようにしている。 Here, some battery devices including a battery and a connector (for example, a charger) that charges and discharges the battery include a controller that controls charging and discharging of the battery. Between the control units of the battery and the connector, it is possible to perform appropriate charging / discharging by communicating various information related to the power of the battery and its charging / discharging, for example, information such as battery voltage and remaining capacity. I have to.
　このような複数の制御部間の通信には、例えばＣＡＮ（Ｃｏｎｔｒｏｌｌｅｒ　Ａｒｅａ　Ｎｅｔｗｏｒｋ）が使用されることがある。ＣＡＮ通信では通常、インピーダンス整合のために通信バスに終端抵抗が２個接続されることになっている。 For example, CAN (Controller Area Network) may be used for such communication between a plurality of control units. In CAN communication, two termination resistors are normally connected to the communication bus for impedance matching.
　ＣＡＮ通信のような通信バスに終端抵抗が２個必要な通信方法を、例えば特許文献１に記載された電池パック（バッテリ）に適用した場合、バッテリの２箇所の端子部各々に標準充電器と急速充電器との２個の充電器を同時に接続すると終端抵抗が３個になってしまう。これにより、通信バスの終端抵抗値が規定値を外れ、好適な通信品質を維持できなくなる可能性がある。 When a communication method such as CAN communication that requires two termination resistors is applied to, for example, a battery pack (battery) described in Patent Document 1, a standard charger is connected to each of two terminal portions of the battery. If two chargers are connected to the quick charger at the same time, the termination resistance becomes three. As a result, the termination resistance value of the communication bus may deviate from the specified value, and it may not be possible to maintain suitable communication quality.
　そこで、二以上の通信バスを構成することが考えられる。しかしながら、単一の通信バスの場合と比較してコストアップとなり、通信の仲介などの制御処理にかかる負荷が増大する。さらに、２個の充電器が接続されたときの充電方法やエラー処理などの制御処理にかかる負荷も増大する。 Therefore, it is conceivable to configure two or more communication buses. However, the cost increases as compared with the case of a single communication bus, and the load on control processing such as communication mediation increases. Furthermore, the load applied to control processing such as a charging method and error processing when two chargers are connected also increases.
　本発明は上記の点に鑑みなされたものであり、通信バスに規定を超える終端抵抗が接続されるのを防止して、バッテリとそのバッテリに対して充放電を行う接続器とを適正に接続することが可能なバッテリ装置及びバッテリを提供することを目的とする。また、それらのバッテリ装置やバッテリを搭載した信頼性の高い電動車両を含む移動体を提供することを目的とする。 The present invention has been made in view of the above points, and prevents a terminal resistor exceeding a specified value from being connected to a communication bus and properly connects a battery and a connector for charging / discharging the battery. It is an object of the present invention to provide a battery device and a battery that can be used. It is another object of the present invention to provide a moving body including a battery device and a highly reliable electric vehicle equipped with the battery.
　上記の課題を解決するため、本発明のバッテリ装置は、充電と放電とが可能であって、充電または放電に用いる端子部が２箇所に設けられたバッテリと、前記バッテリの２箇所の前記端子部のいずれか一方に対して電気的に接続して充電または放電を行う接続器と、前記端子部を介して前記バッテリと前記接続器との間で通信を行うために前記バッテリ及び前記接続器の各々に設けた通信線で構成された単一の通信バスと、前記バッテリ及び前記接続器の各々の前記通信バスに対して設けられた終端抵抗と、を備え、前記バッテリまたは前記接続器が、前記バッテリの一方の前記端子部と前記接続器とが電気的に接続されたときに前記バッテリの他方の前記端子部に対する電気的接続を阻止する接続阻止部を備えることとした。 In order to solve the above-described problems, the battery device of the present invention is capable of charging and discharging, a battery provided with two terminal portions used for charging or discharging, and the two terminals of the battery. A connector that is electrically connected to any one of the units to perform charging or discharging, and the battery and the connector to perform communication between the battery and the connector via the terminal unit Each of the battery and the connector, and a termination resistor provided for the communication bus of each of the battery and the connector, the battery or the connector comprising: In addition, when the one terminal portion of the battery and the connector are electrically connected, a connection blocking portion that blocks electrical connection to the other terminal portion of the battery is provided.
　この構成によれば、バッテリ装置は、バッテリの一方の端子部と接続器とが電気的に接続されたとき、接続阻止部がバッテリの他方の端子部に対する電気的接続を阻止する。したがって、バッテリ装置は単一の通信バスにおいて規定を超える終端抵抗が接続されるのを防止できる。 According to this configuration, in the battery device, when one terminal portion of the battery and the connector are electrically connected, the connection blocking portion blocks electrical connection to the other terminal portion of the battery. Therefore, the battery device can prevent a termination resistor exceeding a specified value from being connected in a single communication bus.
　なお、ここで述べた「単一の通信バス」とは共通の通信が可能となる通信バスのことであり、分岐する通信路が多少存在しても構わない。また、ここで述べた接続阻止部が「電気的接続を阻止する」こととは例えば壁部やシャッター、蓋部、突起などの構造物によって接続器と端子部とを通信可能に接続するのを妨げることを意味する。 Note that the “single communication bus” described here is a communication bus that enables common communication, and there may be some branched communication paths. In addition, the connection blocking unit described here “blocks electrical connection” means that the connector and the terminal unit are communicably connected to each other by a structure such as a wall, shutter, lid, or protrusion. Means blocking.
　また、上記構成のバッテリ装置において、前記接続阻止部は、前記バッテリの一方の前記端子部と前記接続器とが電気的に接続されたときに前記バッテリの他方の前記端子部を塞ぐ壁部で構成されていることとした。 In the battery device having the above-described configuration, the connection blocking portion is a wall portion that closes the other terminal portion of the battery when the one terminal portion of the battery and the connector are electrically connected. It was supposed to be configured.
　この構成によれば、バッテリ装置は、壁部によって前記他方の端子部を塞ぐ。したがって、バッテリ装置は接続阻止部をバッテリまたは接続器に容易に形成することができる。 According to this configuration, the battery device closes the other terminal portion by the wall portion. Therefore, the battery device can easily form the connection blocking portion in the battery or the connector.
　また、上記構成のバッテリ装置において、前記接続阻止部は、前記バッテリの一方の前記端子部と前記接続器とが電気的に接続されたときに前記バッテリの他方の前記端子部を塞ぐように移動するシャッターで構成されていることとした。 Further, in the battery device having the above configuration, the connection blocking unit moves so as to close the other terminal portion of the battery when the one terminal portion of the battery and the connector are electrically connected. It is made up of shutters that perform.
　この構成によれば、バッテリ装置は、シャッターを移動させることによって前記他方の端子部を塞ぐ。したがって、バッテリ装置は２箇所の端子部が比較的離れていても容易に、一方の端子部と接続器とが電気的に接続されたときに他方の端子部に対する電気的接続を阻止することができる。 According to this configuration, the battery device closes the other terminal portion by moving the shutter.

Note that some components are not shown in the perspective views of FIGS.
　バッテリ１０を、第１充電器２０を用いて充電するとき、図３及び図４に示すように第１充電器２０の充電コネクタ２９をバッテリ１０の第１端子部１６に接続する。第１端子部１６と充電コネクタ２９との間では電力端子１６ａ、１６ｂと電力端子２９ａ、２９ｂとが電気的に接続され、通信端子１６ｃ、１６ｄと通信端子２９ｃ、２９ｄとが電気的に接続される。 When charging the battery 10 using the first charger 20, the charging connector 29 of the first charger 20 is connected to the first terminal portion 16 of the battery 10 as shown in FIGS. 3 and 4.
