4.3.2 まずはノートPCを立ち上げた状態で実験

• UD24でチェック

  • BC 1.2でのみ接続している模様

    

• FCOPで< 9.9W for 1分に設定
• PC:起動状態＋約48 %充電で充電開始

  • 最初は大体30 W出ている

  • 充電モニタースクリプト(bcs.sh)で記録

    #!/bin/sh
    
    _start=$(env LANG=C date -j -f "%a %b %d %T %Z %Y" "$(env LANG=C date)" "+%s")
    echo "start:$(env LANG=C date)"
    _n=0
    while true; do
        sleep 1
        _state=$(hwstat | sed -nEe '/^\[battery0\]/,$p' | sed -nEe 's/^[[:space:]]*State:[[:space:]]*//p')
        _capacity=$(hwstat | sed -nEe '/^\[battery0\]/,$p' | sed -nEe 's/^[[:space:]]*Remaining capacity:[[:space:]]*([[:digit:]]+).*$/\1/p')
        _power=$(hwstat | sed -nEe '/^\[battery0\]/,$p' | sed -nEe 's/^[[:space:]]*Present rate:[[:space:]]*([[:digit:]]+).*$/\1/p')
        _voltage=$(hwstat | sed -nEe '/^\[battery0\]/,$p' | sed -nEe 's/^[[:space:]]*Voltage:[[:space:]]*([[:digit:]]+).*$/\1/p')
        : $((_n += 1))
        echo "$_n:$_capacity:$_power:$_voltage"
        if [ $_capacity -gt 77 ]; then
    	echo "$_n:$_capacity:$_power:$_voltage" 2>> data/hwstat.log 1>&2
    	hwstat 2>> data/hwstat.log 1>&2
    	test "$_state" = "discharging" && break
        fi
    done
    _end=$(env LANG=C date -j -f "%a %b %d %T %Z %Y" "$(env LANG=C date)" "+%s")
    : $((_int= _end - _start))
    echo "end($_int):$(env LANG=C date)"

    • hwstat(sysutils/hwstat)を用いて充電状況を吐き出すスクリプト
    • キャパシティ，受給電力，受給電圧を1秒毎に表示
    • キャパシティが77 %以上で接続が切れたら終了
• 95 %で充電終了・切断完了
  • 所要時間: 1 h 36 m 24 s

  • 充電終了前には12 W(15V,0.8A)程度しか出ていない

  • 切断直後の状態(PC側)

    

    • キャパシティ:95 %,電圧:11.55V,電力:4.065W
