Abstract
【解決手段】蓄電池システムは、ある相転移温度で固相と固相との間を潜熱の吸収、放出を伴って可逆的に相転移する蓄熱材によって構成された固体蓄熱部20を備える。固体蓄熱部20は、蓄電池10の温度が相転移温度に達した際に、固相−固相間状態相転移を起こすことにより、蓄電池10の温度を相転移温度に維持する役割を果たす。これにより、固体蓄熱部20が相転移を発生させても固体の状態が維持されるので、固体蓄熱部20の形状を維持するための容器が不要になる。したがって、固体蓄熱部20が蓄電池10から潜熱を吸収する際の容器等の外壁の熱抵抗を低減することができる。
【選択図】図1
Description
以下、本発明の第1実施形態について図を参照して説明する。本実施形態に係る蓄電池システムは、例えばハイブリッド車等の電気自動車に搭載される駆動源である。また、蓄電池システムは、モータジェネレータ等の負荷を駆動するための電源や電子機器の電源等にも用いられる。
(数1)
∫Qinputdt=Cm(ΔT)+ΔH
また、1kg当たりの潜熱量をΔhとすると、潜熱量ΔHは以下の数2で表される。
(数2)
ΔH=mVO2(Δh)
数1は、ある時間までの積算の流入熱量Qinputは温度上昇ΔTと固体蓄熱部20の固相−固相間状態相転移における潜熱ΔHで消費されることを示している。言い換えると、蓄電池システムの温度上昇ΔTが潜熱ΔHによって消費されることで蓄電池システムの温度が一定に保たれる。
本実施形態では、第1実施形態と異なる部分について説明する。図8に示されるように、固体蓄熱部20は、蓄電池10を囲んでいる。具体的には、固体蓄熱部20は、筒状に構成されていると共に、蓄電池10のケースの4側面全体を囲んでいる。つまり、蓄電池10のケースの両端面は固体蓄熱部20から露出している。
本実施形態では、第1、第2実施形態と異なる部分について説明する。図9に示されるように、蓄電池システムは、蓄電池10、固体蓄熱部20、及び流路部30を備えて構成されている。
上記各実施形態で示された蓄電池システムの構成は一例であり、上記で示した構成に限定されることなく、本発明を実現できる他の構成とすることもできる。例えば、蓄電池10は車両に搭載される場合に限られず、蓄電池10は定置用のものでも良い。もちろん、蓄電池10の外形は上述のように直方体に限られず、他の外形が採用されることもある。
