1. a charging system is charged the surface temperature of lithium ion battery with being no more than the ceiling temperature value to described lithium ion battery, it is characterized in that,Comprise:

  • Charger, it possesses the constant current constant voltage characteristic, variable setting electric current in charging process;

    Temperature element (TE, measure the surface temperature of described lithium ion battery;

    AndControl part, described charger carry out constant current control during, reception is from the output of described temperature element (TE, regularly calculate the predicting temperature values that is equivalent to the described surface temperature when supposing with current charging current value described lithium ion cell charging to the charge volume of the regulation that is less than full charge capacity, the result that the target temperature district set in the temperature range lower than described ceiling temperature value according to regular comparison and described predicting temperature values obtain, change the setting electric current of described charger.
