1. thermal-holding type autoamtic cutting off recharger, it is characterized in that:

  • comprise that the moving isolating switch (TS1) of closed type heat, heat keep resistance (R1) and fairing (RC100), the moving isolating switch (TS1) of closed type heat with can discharge and recharge battery and connect and be thermal coupling, the normally closed contact group of the moving isolating switch (TS1) of this closed type heat is in parallel with heat maintenance resistance (R1) to be thermal coupling, heat keeps resistance (R1) to connect with charge power supply, charge power supply by fairing (RC100) with can discharge and recharge battery and connect;

    It is saturated to discharge and recharge battery charge, when battery temperature rises to setting value, the moving isolating switch (TS1) of closed type heat is subjected to thermal cut-out, heat maintenance resistance (R1) in parallel with moving isolating switch (TS1) the normally closed contact group of closed type heat and that be thermal coupling generates heat by electric current, control the moving isolating switch (TS1) of the closed type heat escape state that is heated, and keep resistance (R1) restriction to discharging and recharging the maintenance charging current of battery by heat, when heat keeps resistance to get the first thermal power value, the moving isolating switch (TS1) of closed type heat to described thermal coupling does to postpone heating of reset time, prolong its contact and return the closed time, and the saturated heating of charging once again after the normally closed contact involution makes the moving isolating switch of closed type heat be subjected to thermal cut-out once again, and then forms the complementarity charging of a resting period;

    When heat keeps resistance to get the second thermal power value, the moving isolating switch of closed type heat of institute'"'"'s thermal coupling is heated, keep resistance limits to discharging and recharging the retentivity charging current of battery by heat, wherein the first thermal power value is less than the second thermal power value.
