Lithium battery charging time: The charging battery has a battery charging time problem. With the rechargeable battery such as nickel-hydrogen battery, nickel-cadmium battery and lithium battery in place of a battery and its popularity in the new application, the scientific battery charging time It's necessary to understand. From the market, most of the current constant current charger, that is, the charging current is always the input current marked on the charger.
Since the battery itself produces a back potential, according to different battery capacity and charging The proportional relationship of current, the scientific battery charging time is as follows: battery capacity Watch the battery capacity of the battery to see the input current 1 on the charger, when the charging current is less than 5% of the battery capacity, the battery charging time (hour) = battery Capacity (MAH) ¡Á 1.6 ¡Â Charging current (MA); 2, charging current is greater than 5%, less than 10% equal to battery capacity, battery charging time (hour) = battery capacity (MAH) ¡Á 1.5 ¡Â charging current (MA ); 3, charging current is greater than 10%, less than 15% equal to battery capacity, battery charging time (hour) = battery capacity (MAH) ¡Á 1.
3 ¡Â charging current (MA); 4, charging current is greater than 15%, When it is 20% equal to the battery capacity, the battery charging time (hour) = battery capacity (MAH) ¡Á 1.2 ¡Â charging current (mA); 5, when the charging current is greater than 20% of the battery capacity, the battery charging time (hour) = battery Capacity (MAH) ¡Á 1.1 ¡Â Charging current (MA).
There is also a fast charger, because fast charging uses a large current discharge, it produces high heat, but also in order to prevent excessive hazards during fast charging, the general fast charger sets a control circuit or IC chip to control the battery charging time. When the battery is close to full, the control circuit will automatically transfer to the trickle charging mode, so don't worry too much, it is not necessary to calculate the battery char.
