Description
本発明は、電池セルの温度異常を検出する温度異常検出装置、及び、電池パックに関する。 The present invention relates to a temperature abnormality detection device that detects a temperature abnormality of a battery cell, and a battery pack .
本発明はこのような従来技術の問題点に鑑みてなされたものであり、その目的は、電池セルにおける温度異常の誤検出を抑制することができる温度異常検出装置、及び、電池パックを提供することにある。 The present invention has been made in view of such problems of the prior art, and an object thereof is to provide a temperature abnormality detection device and a battery pack that can suppress erroneous detection of temperature abnormality in a battery cell. There is.
上記温度異常検出装置について、前記被結合部材は、積荷を搬送する産業車両に搭載されるカウンタウェイトであることが好ましい。
カウンタウェイトは、積荷とつりあいをとるための部材であり、重量が重い。このため、体積が大きく、熱容量が大きい。外気温が急激に変動したときに、カウンタウェイトの温度の変動は緩やかであり、電池セルの温度と被結合部材の温度の温度差が過剰に大きくなることをより抑制することができる。
上記温度異常検出装置について、前記ケースの一部はカウンタウェイトであることが好ましい。
上記課題を解決する電池パックは、電池セルと、前記電池セルに熱的に結合される被結合部材と、前記被結合部材の温度を検出する被結合部材用温度センサと、前記電池セルの温度を検出する電池セル用温度センサと、前記電池セルの温度と、前記被結合部材の温度の温度差が閾値以上のときに前記電池セルの温度が異常と判断する制御装置と、を備え、前記被結合部材は、前記電池セルと外気との間に配置されていることを要旨とする。
上記電池パックについて、前記被結合部材は、ウェイト部と、前記ウェイト部から立設したウェイト本体とを備えるカウンタウェイトであり、前記電池セルは、前記ウェイト本体に固定されていてもよい。
上記電池パックについて、前記カウンタウェイトの熱容量は、外気温の変動に対して前記カウンタウェイトの温度が緩やかに変動するような熱容量であることが好ましい。
In the temperature abnormality detection device, it is preferable that the coupled member is a counterweight mounted on an industrial vehicle that transports a load.
The counterweight is a member for balancing with the load and is heavy. For this reason, the volume is large and the heat capacity is large. When the outside air temperature fluctuates rapidly, the temperature variation of the counterweight is gentle, and it is possible to further suppress the temperature difference between the battery cell temperature and the coupled member temperature from becoming excessively large.
In the temperature abnormality detection device, a part of the case is preferably a counterweight.
A battery pack that solves the above problems includes a battery cell, a coupled member that is thermally coupled to the battery cell, a temperature sensor for a coupled member that detects the temperature of the coupled member, and the temperature of the battery cell. A battery cell temperature sensor, and a control device that determines that the temperature of the battery cell is abnormal when a temperature difference between the temperature of the battery cell and the temperature of the coupled member is equal to or greater than a threshold value, The gist is that the member to be coupled is disposed between the battery cell and the outside air.
In the battery pack, the member to be coupled may be a counterweight including a weight portion and a weight main body standing upright from the weight portion, and the battery cell may be fixed to the weight main body.
With respect to the battery pack, it is preferable that the heat capacity of the counterweight is such that the temperature of the counterweight changes gradually with respect to changes in outside air temperature.
