Description

本明細書が開示する技術は、電動車に関し、特に、充電設備によって充電される電動車に関する。 The technology disclosed herein relates to an electric vehicle, and more particularly to an electric vehicle charged by a charging facility.

特許文献１に、充電設備によって充電される電動車が開示されている。この電動車は、充電設備の充電コネクタが着脱可能に接続される充電インレットを備える。 Patent Document 1 discloses an electric vehicle charged by a charging facility. This electric vehicle is equipped with a charging inlet to which the charging connector of the charging equipment is detachably connected.

特開２０１９−１８７０３５号公報Japanese Unexamined Patent Publication No. 2019-187035

一般的に、上記のような電動車では、充電インレットに温度センサが設けられ、温度センサによる測定温度に応じて充電電流が制御されている。これにより、充電インレットと充電コネクタとの接点の過熱を回避しつつ、充電時間の短縮が図られている。しかしながら、充電インレットと充電コネクタとの実際の接点に温度センサを配置することは、充電インレットと充電コネクタとの篏合の妨げとなるため困難である。従って、温度センサによる測定温度は、充電インレットと充電コネクタとの接点における実際の温度に必ずしも一致せず、両者の間には誤差が存在する。特に、充電設備の一部には、充電コネクタの冷却システムを有するものがあり、冷却システムの有無によって、充電インレットと充電コネクタとの間に現れる温度勾配（温度分布）も相違する。従って、温度センサによる測定温度と、接点における実際の温度との間にも、冷却システムの有無によって異なる誤差が生じてしまう。 Generally, in an electric vehicle as described above, a temperature sensor is provided in the charging inlet, and the charging current is controlled according to the temperature measured by the temperature sensor. As a result, the charging time is shortened while avoiding overheating of the contact point between the charging inlet and the charging connector. However, it is difficult to arrange the temperature sensor at the actual contact point between the charging inlet and the charging connector because it hinders the alignment between the charging inlet and the charging connector. Therefore, the temperature measured by the temperature sensor does not always match the actual temperature at the contact point between the charging inlet and the charging connector, and there is an error between the two. In particular, some charging equipment has a cooling system for the charging connector, and the temperature gradient (temperature distribution) that appears between the charging inlet and the charging connector differs depending on the presence or absence of the cooling system. Therefore, a different error occurs between the temperature measured by the temperature sensor and the actual temperature at the contact point depending on the presence or absence of the cooling system.

上記の実情を鑑み、本明細書では、充電インレットと充電コネクタとの接点の温度を、より正確に把握し得る技術を提供する。 In view of the above circumstances, the present specification provides a technique capable of more accurately grasping the temperature of the contact point between the charging inlet and the charging connector.

本明細書が開示する電動車は、充電設備の充電コネクタが着脱可能に接続される充電インレットと、充電インレットの温度を測定する第１温度センサと、充電コネクタの温度に関連する温度関連データを取得する通信装置と、第１温度センサによる測定温度と温度関連データとに基づいて充電コネクタと充電インレットとの間の接点における温度を推定する処理回路とを備える。温度関連データには、充電設備の充電コネクタに対する冷却システムの有無と、充電設備の充電コネクタに設けられた第２温度センサによる測定温度との少なくとも一方が含まれる。 The electric vehicle disclosed in the present specification has a charging inlet to which the charging connector of the charging facility is detachably connected, a first temperature sensor for measuring the temperature of the charging inlet, and temperature-related data related to the temperature of the charging connector. It includes a communication device to be acquired and a processing circuit that estimates the temperature at the contact point between the charging connector and the charging inlet based on the temperature measured by the first temperature sensor and the temperature-related data. The temperature-related data includes at least one of the presence / absence of a cooling system for the charging connector of the charging equipment and the temperature measured by the second temperature sensor provided in the charging connector of the charging equipment.

上記の構成によると、充電インレットと充電コネクタとの間の接点における温度を、充電インレットの第１温度センサによる測定温度に加えて、充電コネクタの温度に関連する温度関連データを利用することで、より正確に推定することができる。特に、温度関連データには、充電設備の充電コネクタに対する冷却システムの有無と、充電設備の充電コネクタに設けられた第２温度センサによる測定温度との少なくとも一方が含まれる。例えば、充電コネクタに対する冷却システムの有無が判明すれば、第１温度センサによる測定温度を用いて接点における温度を推定する関係式を、冷却システムの有無に応じて変更することができる。あるいは、充電コネクタに設けられた第２温度センサによる測定温度が判明すれば、二つの温度センサの間に位置する接点の温度をより正確に推定することができる。その結果、様々な充電設備においても、充電電流をより適切に制御することができ、例えば充電時間の短縮が可能となる。 According to the above configuration, the temperature at the contact point between the charging inlet and the charging connector can be measured by the first temperature sensor of the charging inlet and the temperature related data related to the temperature of the charging connector can be used. It can be estimated more accurately. In particular, the temperature-related data includes at least one of the presence / absence of a cooling system for the charging connector of the charging equipment and the temperature measured by the second temperature sensor provided in the charging connector of the charging equipment. For example, if the presence or absence of a cooling system for the charging connector is known, the relational expression for estimating the temperature at the contact using the temperature measured by the first temperature sensor can be changed according to the presence or absence of the cooling system. Alternatively, if the temperature measured by the second temperature sensor provided on the charging connector is known, the temperature of the contact located between the two temperature sensors can be estimated more accurately. As a result, the charging current can be controlled more appropriately even in various charging facilities, and for example, the charging time can be shortened.

電動車１０とそれを充電する充電設備４０との構成を模式的に示す。The configuration of the electric vehicle 10 and the charging equipment 40 for charging the electric vehicle 10 is schematically shown. 充電インレット２０と、それに接続される充電コネクタ３０とを模式的に示す。The charging inlet 20 and the charging connector 30 connected to the charging inlet 20 are schematically shown. 充電インレット２０と、それに接続される充電コネクタ３０とを模式的に示す図であって、充電コネクタ３０に第２温度センサ３２が設けられたものの一例を示す。It is a figure which shows typically the charging inlet 20 and the charging connector 30 connected to it, and shows an example of the charging connector 30 provided with the 2nd temperature sensor 32.

図面を参照して、実施例の電動車１０について説明する。電動車１０は、図１、図２に示すように充電インレット２０を備える。充電インレット２０は、電動車１０の一部に設けられるが、その位置は特に限定されない。ここでいう電動車１０は、特に限定されないが、例えば電気自動車やプラグインハイブリッド自動車であり、充電設備４０といった外部電源から充電ケーブル４２を通じて受電し、車載の蓄電装置２８で蓄電する充電機構が搭載されている。 The electric vehicle 10 of the embodiment will be described with reference to the drawings. The electric vehicle 10 includes a charging inlet 20 as shown in FIGS. 1 and 2. The charging inlet 20 is provided in a part of the electric vehicle 10, but its position is not particularly limited. The electric vehicle 10 referred to here is not particularly limited, but is, for example, an electric vehicle or a plug-in hybrid vehicle, and is equipped with a charging mechanism that receives power from an external power source such as a charging facility 40 through a charging cable 42 and stores electricity in an in-vehicle power storage device 28. Has been done.

充電インレット２０は、受電側のコネクタであり、充電設備４０の充電コネクタ３０が着脱可能に接続される。従って、充電インレット２０は、外部電源から供給される電力を、充電コネクタ３０を介して受電し、電動車１０に搭載された蓄電装置２８で蓄電する。 The charging inlet 20 is a connector on the power receiving side, and the charging connector 30 of the charging equipment 40 is detachably connected to the charging inlet 20. Therefore, the charging inlet 20 receives the electric power supplied from the external power source via the charging connector 30, and stores the electric power in the electric storage device 28 mounted on the electric vehicle 10.

電動車１０は、さらに第１温度センサ２２を備える。第１温度センサ２２は、充電インレット２０の近傍に位置しており、又は、充電インレット２０に内蔵されており、充電インレット２０の温度を検出する。ここで、第１温度センサ２２の具体的な構成については、特に限定されない。第１温度センサ２２は、充電インレット２０の温度を、直接的又は間接的に測定し得るものであればよい。 The electric vehicle 10 further includes a first temperature sensor 22. The first temperature sensor 22 is located in the vicinity of the charging inlet 20 or is built in the charging inlet 20 to detect the temperature of the charging inlet 20. Here, the specific configuration of the first temperature sensor 22 is not particularly limited. The first temperature sensor 22 may be capable of directly or indirectly measuring the temperature of the charging inlet 20.

電動車１０は、さらに通信装置２４を備える。通信装置２４は、有線又は無線によって、充電設備４０や外部と各種のデータを通信する。通信装置２４は、例えば、充電コネクタ３０の温度に関連する、温度関連データを取得する。温度関連データには、充電設備４０の充電コネクタ３０に対する冷却システム３４の有無が含まれる。通信装置２４における温度関連データの具体的な取得方法については、特に限定されない。通信装置２４は、温度関連データを直接的又は間接的に取得し得るものであればよい。例えば、温度関連データに関する情報が格納されたメモリが電動車１０にさらに備えられており、通信装置２４は当該メモリを参照することによって、間接的に温度関連データを取得してもよい。具体的には、電動車１０のメモリには、複数の充電設備４０について、識別情報と冷却システム３４の有無を記述するデータベースが記憶されていてもよい。この場合、電動車１０の通信装置２４は、温度関連データとして、充電設備４０からその識別情報のみを取得すれば足りる。あるいは、電動車１０の外部に設けられたサーバーと通信装置２４とが通信することによって間接的に温度関連データを取得してもよい。通信装置２４による温度関連データの取得が実行されるのは、電動車１０と充電設備４０とが接続される前であってもよく、接続された後であってもよい。 The electric vehicle 10 further includes a communication device 24. The communication device 24 communicates various data with the charging equipment 40 and the outside by wire or wirelessly. The communication device 24 acquires, for example, temperature-related data related to the temperature of the charging connector 30. The temperature-related data includes the presence / absence of the cooling system 34 for the charging connector 30 of the charging equipment 40. The specific acquisition method of the temperature-related data in the communication device 24 is not particularly limited. The communication device 24 may be any device that can directly or indirectly acquire temperature-related data. For example, the electric vehicle 10 is further provided with a memory in which information related to the temperature-related data is stored, and the communication device 24 may indirectly acquire the temperature-related data by referring to the memory. Specifically, the memory of the electric vehicle 10 may store identification information and a database describing the presence / absence of the cooling system 34 for the plurality of charging facilities 40. In this case, it is sufficient for the communication device 24 of the electric vehicle 10 to acquire only the identification information from the charging equipment 40 as the temperature-related data. Alternatively, the temperature-related data may be indirectly acquired by communicating with the communication device 24 and the server provided outside the electric vehicle 10. The acquisition of the temperature-related data by the communication device 24 may be executed before or after the electric vehicle 10 and the charging facility 40 are connected.

電動車１０は、さらに処理回路２６を備える。処理回路２６は、第１温度センサ２２に接続され、第１温度センサ２２による測定温度、即ち、充電インレット２０の温度を取得する。処理回路２６は、さらに、通信装置２４に接続され、充電コネクタ３０が取得した温度関連データを通信装置２４から取得する。即ち、処理回路２６には、第１温度センサ２２が測定した充電インレット２０の測定温度と、通信装置２４が取得した充電コネクタ３０の温度関連データとが入力される。従って、処理回路２６は、第１温度センサ２２が測定した充電インレット２０の測定温度と、通信装置２４が取得した充電コネクタ３０の温度関連データと、に基づいて充電コネクタ３０と充電インレット２０との間の接点における温度を推定する。充電コネクタ３０と充電インレット２０との間の接点における推定温度が、所定値を超えた場合、処理回路２６は過熱を回避するために、例えば充電電力を制限するよう制御することができる。前記所定値は、充電インレット２０のケーブルの耐熱温度や、充電時間等を考慮して設計されてよい。 The electric vehicle 10 further includes a processing circuit 26. The processing circuit 26 is connected to the first temperature sensor 22 and acquires the temperature measured by the first temperature sensor 22, that is, the temperature of the charging inlet 20. The processing circuit 26 is further connected to the communication device 24, and acquires the temperature-related data acquired by the charging connector 30 from the communication device 24. That is, the measured temperature of the charging inlet 20 measured by the first temperature sensor 22 and the temperature-related data of the charging connector 30 acquired by the communication device 24 are input to the processing circuit 26. Therefore, the processing circuit 26 sets the charging connector 30 and the charging inlet 20 based on the measured temperature of the charging inlet 20 measured by the first temperature sensor 22 and the temperature-related data of the charging connector 30 acquired by the communication device 24. Estimate the temperature at the contacts between them. When the estimated temperature at the contact between the charging connector 30 and the charging inlet 20 exceeds a predetermined value, the processing circuit 26 can be controlled to limit the charging power, for example, in order to avoid overheating. The predetermined value may be designed in consideration of the heat resistant temperature of the cable of the charging inlet 20, the charging time, and the like.

以下、充電コネクタ３０と充電インレット２０との接点を、単に接点と略称することがあり、接点における温度を、単に接点温度と略称することがある。 Hereinafter, the contact point between the charging connector 30 and the charging inlet 20 may be simply abbreviated as the contact point, and the temperature at the contact point may be simply abbreviated as the contact temperature.

上記の構成によると、充電設備４０が、接点の過熱を抑制するための充電コネクタ３０の冷却システム３４を有する場合においても、電動車１０は、より正確に接点温度を推定することができる。電動車１０は、充電インレット２０の第１温度センサ２２による測定に加えて、充電コネクタ３０の温度に関する温度関連データを利用することで、より正確に接点温度を推定することができる。温度関連データには、前述したように、充電設備４０の充電コネクタ３０に対する冷却システム３４の有無が含まれる。 According to the above configuration, even when the charging equipment 40 has a cooling system 34 for the charging connector 30 for suppressing overheating of the contacts, the electric vehicle 10 can estimate the contact temperature more accurately. The electric vehicle 10 can estimate the contact temperature more accurately by using the temperature-related data related to the temperature of the charging connector 30 in addition to the measurement by the first temperature sensor 22 of the charging inlet 20. As described above, the temperature-related data includes the presence / absence of the cooling system 34 for the charging connector 30 of the charging equipment 40.

例えば、充電設備４０が充電コネクタ３０の冷却システム３４を備える場合について以下に説明する。充電インレット２０と充電コネクタ３０との間に現れる温度勾配（温度分布）は、充電コネクタ３０の冷却システム３４の有無によって相違する。詳細には、冷却システム３４を有する充電コネクタ３０は、冷却システム３４を有さない充電コネクタ３０と比較すると、冷却システム３４による冷却によって、低温を維持する。即ち、冷却システム３４の有無によって充電コネクタ３０の温度が変化する。従って、前述したように、充電コネクタ３０の冷却システム３４の有無によって、充電インレット２０と充電コネクタ３０との間に現れる温度勾配（温度分布）も相違する。処理回路２６は、通信装置２４が取得した温度関連データによって、冷却システム３４の有無が判明した場合、接点温度を推定する関係式を、冷却システム３４の有無に応じて変更する。その結果、接点温度をより正確に把握することができる。 For example, a case where the charging equipment 40 includes the cooling system 34 of the charging connector 30 will be described below. The temperature gradient (temperature distribution) that appears between the charging inlet 20 and the charging connector 30 differs depending on the presence or absence of the cooling system 34 of the charging connector 30. Specifically, the charging connector 30 with the cooling system 34 maintains a lower temperature due to cooling by the cooling system 34 as compared to the charging connector 30 without the cooling system 34. That is, the temperature of the charging connector 30 changes depending on the presence or absence of the cooling system 34. Therefore, as described above, the temperature gradient (temperature distribution) that appears between the charging inlet 20 and the charging connector 30 differs depending on the presence or absence of the cooling system 34 of the charging connector 30. When the presence / absence of the cooling system 34 is determined from the temperature-related data acquired by the communication device 24, the processing circuit 26 changes the relational expression for estimating the contact temperature according to the presence / absence of the cooling system 34. As a result, the contact temperature can be grasped more accurately.

一方で、図３に示すように、充電設備４０は第２温度センサ３２を備える場合がある。第２温度センサ３２は、例えば、充電コネクタ３０の近傍に位置しており、又は、充電コネクタ３０に内蔵されており、充電コネクタ３０の温度を検出する。ここで、第２温度センサ３２の具体的な構成については、特に限定されない。第２温度センサ３２は、充電コネクタ３０の温度を、直接的又は間接的に測定し得るものであればよい。 On the other hand, as shown in FIG. 3, the charging equipment 40 may include a second temperature sensor 32. The second temperature sensor 32 is located, for example, in the vicinity of the charging connector 30, or is built in the charging connector 30, and detects the temperature of the charging connector 30. Here, the specific configuration of the second temperature sensor 32 is not particularly limited. The second temperature sensor 32 may be any as long as it can directly or indirectly measure the temperature of the charging connector 30.

充電設備４０が第２温度センサ３２を備える場合について以下に説明する。充電設備４０が第２温度センサ３２を備える場合、通信装置２４は、温度関連データとして、充電コネクタ３０に設けられた第２温度センサ３２による測定温度を取得するとよい。このとき、温度関連データには、充電コネクタ３０の冷却システム３４の有無についての情報が含まれてもよいし、含まれなくてもよい。温度関連データによって第２温度センサ３２による測定温度が判明したとき、処理回路２６は、充電インレット２０に設けられた第１温度センサ２２による測定温度と、第２温度センサ３２による測定温度によって、接点温度をより正確に推定することができる。詳細には、二つの温度センサ２２、３２による各測定温度の間に現れる温度勾配や、各測定温度を用いた接点温度を推定する関係式を用いて、処理回路２６は、接点温度をより正確に推定することができる。 The case where the charging equipment 40 includes the second temperature sensor 32 will be described below. When the charging equipment 40 includes the second temperature sensor 32, the communication device 24 may acquire the temperature measured by the second temperature sensor 32 provided in the charging connector 30 as the temperature-related data. At this time, the temperature-related data may or may not include information about the presence or absence of the cooling system 34 of the charging connector 30. When the temperature measured by the second temperature sensor 32 is found from the temperature-related data, the processing circuit 26 is contacted by the temperature measured by the first temperature sensor 22 provided in the charging inlet 20 and the temperature measured by the second temperature sensor 32. The temperature can be estimated more accurately. Specifically, the processing circuit 26 makes the contact temperature more accurate by using the temperature gradient appearing between the measured temperatures by the two temperature sensors 22 and 32 and the relational expression for estimating the contact temperature using each measured temperature. Can be estimated to.

冷却システム３４の有無を考慮した関係式による接点温度の推定と、第２温度センサ３２による測定温度を考慮した接点温度の推定は、どちらか一方だけが実行されてよく、並行してどちらも実行されてもよい。従って、通信装置２４が取得する温度関連データには、充電コネクタ３０の冷却システム３４の有無と、充電コネクタ３０に設けられた第２温度センサ３２による測定温度との少なくとも一方が含まれればよい。以上の構成により、電動車１０は様々な充電設備４０においても、充電電流をより適切に制御することができる。その結果、例えば充電設備４０からの充電の時間短縮が可能となる。 Only one of the contact temperature estimation by the relational expression considering the presence or absence of the cooling system 34 and the contact temperature estimation considering the measurement temperature by the second temperature sensor 32 may be executed, and both are executed in parallel. May be done. Therefore, the temperature-related data acquired by the communication device 24 may include at least one of the presence / absence of the cooling system 34 of the charging connector 30 and the temperature measured by the second temperature sensor 32 provided in the charging connector 30. With the above configuration, the electric vehicle 10 can more appropriately control the charging current even in various charging facilities 40. As a result, for example, the charging time from the charging equipment 40 can be shortened.
