Slow charge full, fast charge about 90%.
Most of the time required for fast charging is based on charging to 80%, because the charging current will be limited after fast charging to 80% of the power to protect the longer service life of the NezhV power battery.
High temperature and increased voltage will accelerate the aging speed of the battery, fast charging is mainly achieved by increasing the voltage or current, which will inevitably increase the loss of the battery. However, within two years, if the battery capacity does not decrease significantly, the loss caused by fast charging can be basically accepted.
