The practice of measuring electric vehicle (EV) charging efficiency by the time it takes to reach\u00a080% state of charge (SOC)<\/strong>\u00a0instead of\u00a0100%<\/strong>\u00a0is based on several technical and practical reasons:<\/p>\n

Battery Chemistry & Charging Curve<\/h3>\n

EV batteries follow a non-linear charging curve, where:<\/p>\n

    \n
  • 0% to 80%: Charging is fast because the battery can accept high power (constant current phase).<\/li>\n
  • 80% to 100%: The charging rate slows dramatically (constant voltage phase) to protect the battery from stress and overheating.<\/li>\n<\/ul>\n

    This means that:<\/p>\n

      \n
    • The first 80% is much quicker.<\/li>\n
    • The last 20% takes disproportionately longer (sometimes as long as the first 80%).<\/li>\n<\/ul>\n

      Let’s analyze it from the following aspects:<\/h3>\n

      1. Power = Voltage * Current<\/p>\n

      2. Constant Voltage charging & Constant Current charging<\/p>\n

      3. Optimal charging curve. The on-board BMS system will communicate with the\u00a0Laddare f\u00f6r elfordon<\/strong>\u00a0based on information such as battery status\/ temperature\/ current capacity, and maintain the most suitable power for charging in the most suitable way.<\/p>\n

      4. How to charge an EV in the healthiest way?<\/p>\n

      Do not fully load, slow charging is the main method, and fast charging is supplemented. Please keep the battery at 20%~30% when parked for a long time, it is best to charge slowly every 3 months, and then discharge to 20%~30%.<\/p>","protected":false},"excerpt":{"rendered":"
