Description

本考案は、電解液中の電極にサルフェーション現象で形成される非伝導性の硫酸鉛（ＰｂＳＯ4）皮膜を分解し除去するエネルギーを付与するパルス状の電圧を印加する手段を搭載した鉛蓄電池に関する。 The present invention relates to a lead-acid battery equipped with means for applying a pulsed voltage for applying energy for decomposing and removing a nonconductive lead sulfate (PbSO4) film formed by a sulfation phenomenon on an electrode in an electrolytic solution.

鉛蓄電池において、電極に形成されるサルフェーションが電池寿命を短縮させる問題がある。サルフェーションとは、鉛蓄電池の放電によって生成する硫酸鉛（ＰｂＳＯ4）が、放電条件や放置されるときの周囲温度の上下、振動等によって電解液中の電極板上に析出し、次第に成長して不導体皮膜を形成する現象である。これによって内部抵抗が増大し、出力電圧が低下して短期間に使用不能になる。 In lead-acid batteries, sulfation formed on the electrodes has a problem of shortening the battery life. In sulfation, lead sulfate (PbSO4) produced by the discharge of a lead-acid battery precipitates on the electrode plate in the electrolytic solution due to discharge conditions, up and down ambient temperature when left to stand, vibrations, etc., and grows gradually. It is a phenomenon that forms a conductor film. As a result, the internal resistance increases, the output voltage decreases, and it becomes unusable in a short time.

硫酸鉛皮膜の成長阻止の為には、放電条件、温度、振動等を細心の注意を持って管理する必要がある。しかしながら、実際に使用者が絶えずこのような注意をはかることは極めて困難である。よって、パルス状の電圧を外部電極から常時印加するようにし、パルス状電気エネルギーにて硫酸鉛（ＰｂＳＯ4）皮膜を常に分解除去して大きく成長させないことで問題解決する技術が開発されている。
In order to prevent the growth of the lead sulfate film, it is necessary to manage discharge conditions, temperature, vibration, etc. with great care. However, it is extremely difficult for a user to take such care constantly. Therefore, a technique has been developed to solve the problem by constantly applying a pulsed voltage from the external electrode and constantly removing and removing the lead sulfate (PbSO4) film with pulsed electric energy so as not to grow greatly.

たとえば、WO 2004/030138、WO 2004/030137に記載された鉛電池に生ずる硫酸鉛皮膜の方法と装置が、こういった公知技術である。かかる電気エネルギー源は鉛蓄電池自体から得られるので、鉛蓄電池の外部電極にパルス状電気エネルギー発生器を接続すればよい。こうすれば、パルス状の電圧が外部電極から常時印加される。 For example, a known method and apparatus for a lead sulfate film formed on a lead battery described in WO 2004/030138 and WO 2004/030137 are known techniques. Since such an electrical energy source is obtained from the lead storage battery itself, a pulsed electrical energy generator may be connected to the external electrode of the lead storage battery. In this way, a pulsed voltage is always applied from the external electrode.

パルス状電気エネルギー発生器を鉛蓄電池に接続する際に以下の問題がある。たとえば、自動二輪用の小型鉛蓄電池にて、外付けでパルス状電気エネルギー発生器を設置しようとしても、設置スペースが限られ設置困難で、かろうじて設置しても、発生器脱落の恐れがある。自動二輪用に限らず、鉛蓄電池を要する機器は小型化され、内装される部品群が過密化されており、同様の問題がある。本考案は、鉛蓄電池とパルス状電気エネルギー発生器の構成を最適化し、設置スペースの問題を解決することを目的とする。 There are the following problems when connecting a pulsed electric energy generator to a lead acid battery. For example, even if an external pulsed electric energy generator is installed in a small lead-acid battery for motorcycles, the installation space is limited and installation is difficult, and even if it is barely installed, the generator may fall off. Not only for motorcycles, but devices that require lead-acid batteries are miniaturized, and the interior parts are overcrowded, and there are similar problems. An object of the present invention is to optimize the configuration of a lead storage battery and a pulsed electric energy generator to solve the problem of installation space.

パルス状電気エネルギー発生器を鉛蓄電池近傍に設置するには鉛蓄電池自体に嵌合され一体化された構成がよい。そこで本考案では、周縁が平板状絶縁部材で包囲された外部電極を有する鉛蓄電池を対象とし、平板状絶縁部材に凹部を形成し、該凹部に外部電極に対しパルス状の電圧を印加する手段（パルス状電気エネルギー発生器）を嵌合した。 In order to install the pulsed electric energy generator in the vicinity of the lead storage battery, a configuration in which the pulsed electric energy generator is fitted and integrated with the lead storage battery itself is preferable. Therefore, the present invention is directed to a lead-acid battery having an external electrode whose periphery is surrounded by a flat plate-like insulating member. (Pulse electric energy generator) was fitted.

平板状絶縁部材の絶縁耐力にて、凹部の形成、および、パルス状電気エネルギー発生器の配設で絶縁破壊の問題が生じないよう設計することが必要である。パルス状電気エネルギー発生器の回路を半導体機器で小型化すれば、実用的な鉛蓄電池に適用するパルス状電気エネルギー発生器の厚みを２ｃｍ以下に薄くできる。また、パルス状電気エネルギー発生器の筐体を絶縁性の高い材料とすればよい。これらの工夫を考慮して設定し、絶縁破壊の問題が生じない２ｃｍ以下の深さの凹部を平板状絶縁部材に形成し、そこにパルス状電気エネルギー発生器を嵌合すればよい。 It is necessary to design so that the problem of dielectric breakdown does not occur in the formation of the recess and the provision of the pulsed electric energy generator by the dielectric strength of the flat insulating member. If the circuit of the pulsed electric energy generator is miniaturized with a semiconductor device, the thickness of the pulsed electric energy generator applied to a practical lead-acid battery can be reduced to 2 cm or less. The casing of the pulsed electric energy generator may be made of a highly insulating material. It is only necessary to set these ingenuity, and to form a recess having a depth of 2 cm or less in the flat insulating member so as not to cause a problem of dielectric breakdown, and to fit a pulsed electric energy generator there.

鉛蓄電池とパルス状電気エネルギー発生器の構成を最適化し設置スペースの問題が解決でき、電極に形成されるサルフェーション形成がパルス状電気エネルギーで抑制され電池寿命の短縮を防止できる。 The configuration of the lead storage battery and the pulsed electric energy generator can be optimized to solve the problem of installation space, and the formation of sulfation formed on the electrodes can be suppressed by the pulsed electric energy to prevent the battery life from being shortened.
