Method and system for controlling charging parameters of a battery using a plurality of temperature ranges and counters and parameter sets

A battery charging system comprising:

• a battery;
• a battery charger configured to charge the battery;
• a temperature sensor configured to sense a temperature of the battery;
• a microcontroller, wherein the microcontroller is configured to:
• communicate with the battery charger and the temperature sensor;
• determine whether the battery is being charged;
• receive a sensed battery temperature;
• compare the sensed battery temperature to a first temperature range;
• provide a first and second count;
• increment the first count when the sensed battery temperature falls within the first temperature range and increment a second count when the sensed battery temperature falls outside the first predetermined temperature range;
• compare the first and second charging frequency to the charging reference frequency;
• resetting the first count when the second count is greater than the reference count and resetting the second count when the first count is greater than the reference count;
• and
• select the first charging parameter set when the first charging number is greater than the charging reference number and select the second charging parameter set when the second charging frequency is greater than the charging refereance frequency.
