Why is the new battery not fully charging?
1 Answers
It may be due to the charger's current being too small, resulting in a longer charging time. Below are the detailed explanations: Introduction: The indicator for a fully charged electric vehicle battery is generally when the light turns green. If the light remains red during charging, it may be mistakenly thought that the battery is not fully charged. Overcharging should be avoided, and the charging time should not exceed 10 hours in principle. The most accurate measure of whether the battery is fully charged is the charging capacity, which is generally 1.03 to 1.05 times the discharge capacity. If the light does not turn green for a long time, it means the battery is being charged with a small current continuously, maintaining a high voltage state and causing overcharging. Charging light not turning green: If the charging environment temperature is too high (exceeding 45 degrees Celsius), the battery's charging voltage may not reach the limit value, and the charging current remains at a high level without dropping to the inflection point current value, resulting in the charger's light not turning green. If the charger's parameters do not match the battery, it can lead to long-term overcharging or undercharging, eventually causing the battery to lose water and the charger's light not to turn green. If there is too much acid inside the battery, it can disrupt the internal oxygen cycle, leading to "thermal runaway" and preventing the charger's light from turning green.
