The normal power range for charging electric vehicles is generally as follows:
1. Common power range: The power of electric vehicle chargers is usually between 120W and 180W. This range applies to most electric vehicles, especially those equipped with 48V batteries.
2. Specific power and battery capacity relationship: For a 48V battery with a capacity of 10 to 14AH, the charging power is approximately 120W. For a 48V battery with a capacity of 17 to 22AH, the charging power is approximately 180W.
3. Power variation during charging process: Phase 1: At the beginning of charging, the charging current is set to a relatively high value, with an electric power of about 110W, to meet the demand for fast charging. Phase 2: When the battery is charged to nearly 90% capacity, the charging current gradually decreases to about 0.5 to 1 ampere, and the electrical power is correspondingly reduced to about 60W to protect the battery and avoid overcharging. Trickle charging stage: When the battery is fully charged, the charger will enter trickle charging mode, where the power consumption is very low, about 10W, to maintain stable battery power.
The normal power range for charging electric vehicles is between 120W and 180W, depending on the voltage and capacity of the battery. During the charging process, the power will vary with different charging stages.
