Description

本発明は、電池における熱管理技術に関し、特に、相変化材料による熱管理および空気による熱管理を組み合わせた階段式の電池熱管理技術に関する。   The present invention relates to a thermal management technique for a battery, and more particularly to a stepped battery thermal management technique that combines thermal management with a phase change material and thermal management with air.

電池は高いエネルギー密度および出力密度を有するエネルギー蓄積素子であり、電気自動車の動力源として幅広く応用されている。しかしながら、充放電過程において、電池内部における電気化学反応は大量の熱を生じうる。局部に蓄積された熱により電池の温度が高すぎて、熱暴走状態になりうるため、電池が自然発火し、ひいては爆発してしまい、人の安全を脅かす。また、電池の電極附近の電気化学反応がより激しいため、電池の温度を不均一にし、電池のサイクル寿命を大幅に短縮させる。電池の作動信頼性を保証するとともに電池のサイクル寿命を延長し、電気自動車の全体的性能を向上させ、持続的な発展を実現するためには、合理的な電池熱管理システムを設計し、電池の正常動作温度を維持するとともに温度の均一性を向上させなければならない。   A battery is an energy storage element having high energy density and power density, and is widely applied as a power source for electric vehicles. However, during the charge / discharge process, the electrochemical reaction inside the battery can generate a large amount of heat. The temperature of the battery is too high due to the heat accumulated in the local area, which can lead to a thermal runaway state, and the battery spontaneously ignites and eventually explodes, threatening human safety. In addition, the electrochemical reaction near the battery electrode is more intense, making the battery temperature non-uniform and greatly reducing the cycle life of the battery. In order to ensure battery operating reliability and extend battery cycle life, improve the overall performance of electric vehicles and achieve sustainable development, we designed rational battery thermal management systems, The normal operating temperature must be maintained and the temperature uniformity should be improved.

近年、空気冷却、液体冷却、ヒートパイプおよび相変化材料などの温度制御技術は、すでに電池熱管理への応用に成功し、電池の動作温度を大幅に低下させている。しかしながら、熱管理システムの伝熱性能の向上により電池発熱の相違性が拡大され、電池の局部の温度差をさらに大きくし、電池サイクルの使用需要に満たすことが難しく、電気自動車のランニングコストを増加させている。電気自動車の走行距離の増加に伴い、電池温度の均一性は電池熱管理システムに対してさらに厳しい要求を出している。   In recent years, temperature control technologies such as air cooling, liquid cooling, heat pipes and phase change materials have already been successfully applied to battery thermal management, and the operating temperature of the battery has been greatly reduced. However, by improving the heat transfer performance of the thermal management system, the difference in battery heat generation is expanded, the temperature difference in the local part of the battery is further increased, it is difficult to meet the battery cycle usage demand, and the running cost of the electric vehicle is increased. I am letting. With the increasing travel distance of electric vehicles, the uniformity of battery temperature places more stringent demands on battery thermal management systems.

The outer ribs of the phase change material box away from the electrodes are denser than the outer ribs of the phase change material box close to the electrodes, and the gaps between the battery 104, the phase change material box, the base 101 and the cover 301. Constitutes an air duct.

上記相変化材料箱の数は２つまたは２つ以上であり、本実施例では３つの相変化材料箱を例としている。異なる相変化材料箱の内部には熱伝導性能の異なる相変化材料が満たされており、相変化材料の熱伝導率係数、相変化潜熱は階段式に分布され、鉛直下方向に沿って徐々に小さくなり、電池の電極から離れているところに充填された相変化材料の熱伝導率係数、相変化潜熱は電極に近接する位置より高く、単一電池の温度均一性を効果的に制御する。相変化材料は複合有機相変化材料、複合無機相変化材料およびカプセルタイプの相変化材料であってもよい。相変化材料箱は相変化材料の漏洩を防止することができる。   The number of the phase change material boxes is two or more, and in this embodiment, three phase change material boxes are taken as an example. Different phase change material boxes are filled with phase change materials with different heat conduction performance, and the thermal conductivity coefficient and phase change latent heat of the phase change material are distributed stepwise and gradually along the vertical downward direction. The thermal conductivity coefficient, phase change latent heat, of the phase change material filled away from the battery electrode is smaller than the position close to the electrode, effectively controlling the temperature uniformity of a single battery. The phase change material may be a composite organic phase change material, a composite inorganic phase change material, and a capsule type phase change material. The phase change material box can prevent leakage of the phase change material.

相変化材料箱内にはいずれも内側リブ５０１が設置されており、相変化材料箱の伝熱性能を向上させる。鉛直下方向に沿って密度は徐々に小さくなっており、電池の電極から離れている内側リブ５０１の密度は電極に近接している内側リブの密度より高く、単一電池の温度差を減少させる。相変化材料箱および内側リブはアルミナセラミックスなどの高熱伝導絶縁材料を採用することができ、内側リブは棒状であってもよい。   Inside the phase change material box, inner ribs 501 are installed to improve the heat transfer performance of the phase change material box. The density gradually decreases along the vertically downward direction, and the density of the inner rib 501 away from the battery electrode is higher than the density of the inner rib close to the electrode, thereby reducing the temperature difference of the single battery. . The phase change material box and the inner rib can employ a high thermal conductive insulating material such as alumina ceramics, and the inner rib may be rod-shaped.

ベース１０１に開設された凹溝１０３は、電池１０４および下部相変化材料箱１０７を固定するのに用いられ、ねじ孔１０２が設置されており、カバー３０１におけるねじ孔３０４に対応し締め付けられている。カバー３０１、ベース１０１内部の隙間部分は空気ダクトを構成することができ、カバー３０１には入気口３０２および出気口３０３が設置されている。カバーおよびベース材料は、軽量且つ高熱伝導性の銅、低炭素鋼およびアルミニウム合金などの材料を選択してもよい。   The concave groove 103 formed in the base 101 is used to fix the battery 104 and the lower phase change material box 107, is provided with a screw hole 102, and is tightened corresponding to the screw hole 304 in the cover 301. . The gap portion inside the cover 301 and the base 101 can constitute an air duct, and an air inlet 302 and an air outlet 303 are installed in the cover 301. The cover and base material may be selected from materials such as lightweight, high thermal conductivity copper, low carbon steel and aluminum alloys.

相変化材料箱の両側に配置された外側リブ１０８は、空気と相変化材料箱との間の接触面積を増加させる。外側リブ１０８の密度は鉛直下方向に沿って徐々に小さくなっており、電池の電極から離れている相変化材料箱の外側リブ１０８は、電極に近接している相変化材料箱の外側リブ１０８より密度が高く、電池の電極附近領域の放熱を強化し、単一電池の温度均一性を向上させる。   Outer ribs 108 located on either side of the phase change material box increase the contact area between the air and the phase change material box. The density of the outer ribs 108 gradually decreases along the vertically downward direction, and the outer rib 108 of the phase change material box away from the electrode of the battery is the outer rib 108 of the phase change material box adjacent to the electrode. It has higher density, enhances heat dissipation near the battery electrode, and improves temperature uniformity of a single battery.

空気の流れ方向に沿って、同一水平位置の相変化材料箱両側の外側リブ１０８の密度および長さは階段式に分布されており、同一水平位置の相変化材料箱の外側リブは空気の流れ方向に沿って長さおよび密度が階段式に分布されており、出気口３０３附近位置の外側リブの密度および長さは入気口３０２附近の外側リブの密度および長さより大きく、空気ダクトの下流に位置する電池の放熱を強化し、上流側の電池と下流側の電池との間の温度差を減少し、電池パック全体の温度均一性を向上させる。外側リブの材料は高い熱伝導能力を有するステンレス、銅アルミニウム合金および低炭素鋼を使用してもよい。   Along the air flow direction, the density and length of the outer ribs 108 on both sides of the phase change material box at the same horizontal position are distributed stepwise, and the outer ribs of the phase change material box at the same horizontal position are air flow. The length and density are distributed stepwise along the direction, and the density and length of the outer rib near the air outlet 303 are larger than the density and length of the outer rib near the air inlet 302, and the air duct The heat dissipation of the battery located downstream is enhanced, the temperature difference between the upstream battery and the downstream battery is reduced, and the temperature uniformity of the entire battery pack is improved. As the material of the outer rib, stainless steel, copper aluminum alloy and low carbon steel having high heat conduction ability may be used.

絶縁熱伝導剤４０２は、主に電池と相変化材料箱との間の接触熱抵抗を減少し、伝熱性能を向上させ、高い熱伝導率係数を有する熱伝導シリコーングリースおよび絶縁熱伝導両面テープを採用する。   Insulating thermal conductive agent 402 mainly reduces the contact thermal resistance between the battery and the phase change material box, improves the heat transfer performance, and has a high thermal conductivity coefficient and the insulating thermal conductive double-sided tape. Is adopted.
