Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power.

Ordinary chargers are old‐fashioned chargers, charging, whether the battery is full or not, it will keep charging. Now the electric car charger, whether segmented or non‐segmented, without exception, all are intelligent chargers. Intelligent charger in the charging process without human control, the initial charging is a high‐current rapid charging, with the battery voltage increases, the charging current will automatically reduce, when the battery is close to full charge, the charger will automatically enter the trickle charging state, the battery is completely full, the charger will automatically stop charging. If your charger is intelligent, you don't need to adjust it again and again, you can set the current gear at a random gear and stop caring about it, and it will stop when it is fully charged.

Our self‐developed intelligent charger has different charging modes such as intelligent two‐stage charging, five‐stage charging, etc., which can repair many kinds of batteries in different ways.
