Description

本発明は、車両に搭載される電池パックから放射される電磁波を遮蔽する車両の電磁波遮蔽構造に関する。 The present invention relates to a vehicle electromagnetic wave shielding structure that shields electromagnetic waves radiated from a battery pack mounted on the vehicle.

従来、電気自動車などの電池ケースに電磁波を遮蔽する機能を付加することが知られている。特許文献１には、樹脂製の電池ケースの蓋に電磁波遮蔽シートを配設することが示されている。電磁波遮蔽シートとしては、プラスチックのシートに導電性の金属を配合することで導電性を付与したものが挙げられている。 Conventionally, it is known to add a function of shielding electromagnetic waves to a battery case of an electric vehicle or the like. Patent Document 1 discloses that an electromagnetic wave shielding sheet is arranged on the lid of a resin battery case. As the electromagnetic wave shielding sheet, a sheet in which conductivity is imparted by blending a conductive metal with a plastic sheet is mentioned.

ここで、電気自動車などの電池は、大電力であり多くの電池セルを必要とする。このため、複数の電池セルからなる電池スタックを設け、これを複数接続してケースに収容した電池パックが利用される。 Here, a battery of an electric vehicle or the like has a large electric power and requires many battery cells. Therefore, a battery pack composed of a plurality of battery cells is provided, and a plurality of battery stacks are connected and housed in a case.

また、車両の点検修理時などに、高電圧の電池出力を他から切り離す必要があり、電池パックには、サービスプラグが搭載される場合が多い。このサービスプラグは、これを電池パックから引き抜くことで、電池パックの出力を切断するものである。このサービスプラグは、必要時に安全かつ容易に操作できるように設置する必要があり、例えば車両のフロアから突出させて配置し、これをカバーで覆う場合がある。これによって、通常時はカバーで保護し、必要な場合にカバーを外し、操作できる。 In addition, it is necessary to disconnect the high-voltage battery output from others when inspecting and repairing the vehicle, and the battery pack is often equipped with a service plug. This service plug cuts off the output of the battery pack by pulling it out of the battery pack. The service plug needs to be installed so that it can be safely and easily operated when needed, for example, it may be placed so as to project from the floor of the vehicle and covered with a cover. This allows you to protect it with a cover during normal times and remove and operate it if necessary.

When mounted on a vehicle, for example, the tapered portion is located in front and the front of the drawing is located above the vehicle. The front side of the case 12 is tapered in the left-right direction, and the bottom surface also faces diagonally upward toward the front, so that the space 12a on the front side of the case 12 is relatively narrow. In this space 12a, a battery control unit 14, which is a circuit block that controls charging / discharging of the battery, is arranged. Further, the space 12b on the rear side of the case 12 is rectangular parallelepiped and relatively wide, and a plurality of battery stacks 20 are accommodated therein. The upper surface of the case 12 is a flat surface, and the lid is arranged here.

電池パック１０の充放電のためのケーブル１６は、電池制御部１４を介し、電池スタック２０に接続される。この例において、複数の電池スタック２０は、４列でこれらが直列接続されている。図においては、電流が、上から１番目の電池スタック２０において左から右に流れ、３番目の電池スタック２０において右から左に流れ、２番目の電池スタック２０において左から右に流れ、４番目の電池スタック２０において右から左に流れる。従って、１番目の電池スタック２０の左側が負極端、４番目の電池スタック２０の左側が正極端となっている。 The cable 16 for charging / discharging the battery pack 10 is connected to the battery stack 20 via the battery control unit 14. In this example, the plurality of battery stacks 20 are connected in series in four rows. In the figure, the current flows from left to right in the first battery stack 20 from the top, from right to left in the third battery stack 20, and from left to right in the second battery stack 20, fourth. Flows from right to left in the battery stack 20 of. Therefore, the left side of the first battery stack 20 is the negative end, and the left side of the fourth battery stack 20 is the positive end.

そして、１番目の電池スタック２０から３番目の電池スタック２０への電流の経路にサービスプラグ４０が配置されており、このサービスプラグ４０は、１番目の電池スタック２０と２番目の電池スタックの間の上方に位置しており、図において右から左に向けて電流を流す。 A service plug 40 is arranged in the current path from the first battery stack 20 to the third battery stack 20, and the service plug 40 is located between the first battery stack 20 and the second battery stack. It is located above, and the current flows from right to left in the figure.

「サービスプラグ」
図２は、サービスプラグ４０を説明する模式図であり、（ａ）は切断状態、（ｂ）は接続状態を示す。サービスプラグ４０は、レセプタクル４６と対で使用する。すなわち、サービスプラグ４０をレセプタクル４６に挿入することで電池パック１０が接続状態となり、サービスプラグ４０をレセプタクル４６から引き抜くことで電池パック１０が切断状態となる。 "Service plug"
2A and 2B are schematic views illustrating a service plug 40, where FIG. 2A shows a disconnected state and FIG. 2B shows a connected state. The service plug 40 is used in pairs with the receptacle 46. That is, the battery pack 10 is in the connected state by inserting the service plug 40 into the receptacle 46, and the battery pack 10 is in the disconnected state by pulling out the service plug 40 from the receptacle 46.

サービスプラグ４０は、樹脂製の基体４２と、Ｕ字状の線路４４からなり、線路４４の両端４４ａ，４４ｂが基体４２から突出している。レセプタクル４６は、電池パック１０内の配線（１番目と３番目の電池スタック２０の接続配線）の途中に配置され、サービスプラグ４０の両端４４ａ，４４ｂを受け入れる受け口４６ａ，４６ｂを有している。そして、両端４４ａ，４４ｂを受け口４６ａ，４６ｂに挿入することでサービスプラグ４０により電池パック１０が接続状態となり、両端４４ａ，４４ｂを受け口４６ａ，４６ｂから引き抜くことで、サービスプラグ４０により電池パックが切断状態になる。 The service plug 40 is composed of a resin base 42 and a U-shaped line 44, and both ends 44a and 44b of the line 44 project from the base 42. The receptacle 46 is arranged in the middle of the wiring (connection wiring of the first and third battery stacks 20) in the battery pack 10 and has receiving ports 46a and 46b for receiving both ends 44a and 44b of the service plug 40. Then, the battery pack 10 is connected by the service plug 40 by inserting the both ends 44a and 44b into the receiving ports 46a and 46b, and the battery pack is cut by the service plug 40 by pulling out the both ends 44a and 44b from the receiving ports 46a and 46b. Become a state.

図３は、サービスプラグ４０の配置状態を示す図である。ケース１２の蓋１８のサービスプラグ４０の位置には、開口が設けられている。蓋１８の上には車室の床を構成するフロアパネル５２が位置しており、このフロアパネル５２の蓋の開口に対応した位置にも開口が設けられており、両開口が一体となって開口５０を形成している。そして、サービスプラグ４０が開口５０から車室側に突出している。また、このサービスプラグ４０の上方を覆うように内装材５６が配置されている。 FIG. 3 is a diagram showing an arrangement state of the service plug 40. An opening is provided at the position of the service plug 40 of the lid 18 of the case 12. A floor panel 52 constituting the floor of the vehicle interior is located on the lid 18, and an opening is also provided at a position corresponding to the opening of the lid of the floor panel 52, and both openings are integrated. It forms an opening 50. The service plug 40 projects from the opening 50 toward the vehicle interior. Further, the interior material 56 is arranged so as to cover the upper part of the service plug 40.

サービスプラグ４０のＵ字状の線路４８の電流の方向が図１に示す電流の方向と同じ方向である。なお、サービスプラグ４０は基体４２をつかんで操作する。レセプタクル４６は、ケース１２などに適宜手段で固定される。また、サービスプラグ４０と、レセプタクル４６の係合には、別途ロック手段なども設けられるとよい。 The direction of the current of the U-shaped line 48 of the service plug 40 is the same as the direction of the current shown in FIG. The service plug 40 is operated by grasping the substrate 42. The receptacle 46 is appropriately fixed to the case 12 or the like. Further, a locking means or the like may be separately provided for engaging the service plug 40 and the receptacle 46.

「放射磁界の低減」
図４は、電池スタック２０と、サービスプラグ４０の電流の方向について示す図であり、（ａ）は平面模式図、（ｂ）は（ａ）のＸ－Ｘ断面模式図である。このように、２つの電池スタック２０には、同一の方向の電流が流れ、この電流に重畳される高周波により放射磁界を生じる。ここで、２つの電池スタック２０の中間の上方には、サービスプラグ４０が位置しており、ここにおいて２つの電池スタック２０とは逆方向の電流が流れる。このため、これに重畳されている高周波も位相が逆転しており、従ってサービスプラグ４０から放射される磁界が２つの電池スタック２０から放射される磁界によって打ち消されることになる。特に、２つの電池スタック２０の中間の上方にサービスプラグ４０が位置するため、２つの電池スタック２０からの放射磁界がサービスプラグ４０の側方および上方に回り込みやすく、サービスプラグ４０から側方および上方に向けての放射磁界を効果的に打ち消すことができる。 "Reduction of radiated magnetic field"
4A and 4B are views showing the directions of currents of the battery stack 20 and the service plug 40, where FIG. 4A is a schematic plan view and FIG. 4B is a schematic cross-sectional view taken along the line XX of FIG. 4A. In this way, currents in the same direction flow through the two battery stacks 20, and a radiated magnetic field is generated by the high frequency superimposed on the currents. Here, the service plug 40 is located above the middle of the two battery stacks 20, where a current flows in the direction opposite to that of the two battery stacks 20. Therefore, the phase of the high frequency superimposed on this is also reversed, so that the magnetic field radiated from the service plug 40 is canceled by the magnetic field radiated from the two battery stacks 20. In particular, since the service plug 40 is located above the middle of the two battery stacks 20, the radiated magnetic field from the two battery stacks 20 easily wraps around the service plug 40 sideways and above, and laterally and above the service plug 40. It is possible to effectively cancel the radiated magnetic field toward.

このようにして、本実施形態によれば、サービスプラグ４０からの放射磁界、すなわち放射電磁波を２つの電池スタック２０からの放射磁界によって低減することが可能となる。 In this way, according to the present embodiment, the radiated magnetic field from the service plug 40, that is, the radiated electromagnetic wave can be reduced by the radiated magnetic field from the two battery stacks 20.

「他の構成例」
図５は、他の構成例を示す図であり、（ａ）は平面模式図、（ｂ）は（ａ）のＹ－Ｙ断面模式図である。この例では、１つの電池スタック２０の上方に電池スタック２０とは電流の方向が反対のサービスプラグ４０を配置する。これによって、サービスプラグ４０からの放射磁界を低減することができる。 "Other configuration examples"
5A and 5B are views showing another configuration example, where FIG. 5A is a schematic plan view and FIG. 5B is a schematic cross-sectional view taken along the line YY of FIG. 5A. In this example, the service plug 40 whose current direction is opposite to that of the battery stack 20 is arranged above one battery stack 20. Thereby, the radiated magnetic field from the service plug 40 can be reduced.
