Referring to fig. 1, in the configuration method of the universal charging curve of the present invention, a data interface configures corresponding parameters to a control chip through communication interfaces such as a serial port and a CAN; the general charging curve is divided into the following 10 stages:
s0: a waiting stage;
S1-S6: a charging stage;
s7: sufficiency stage
S8: a replenishing stage;
s9: a failure stage;
wherein: each phase is controlled by 5 settable parameters: a constant voltage set value, a constant current set value, a state conversion voltage value, a state conversion current value and stage time;
the constant voltage set value is used for controlling the highest output voltage of the stage, and the temperature compensation is carried out by the temperature compensation value after the setting of the value is finished;
the constant current set value is the maximum output current that controls the stage, if the value is set to 0 then the parameter is not functional;
when the output voltage of the charger is greater than or equal to the value, the state conversion voltage value is delayed by 5s and then is shifted to the next stage (the soft start process needs to be avoided);
the state conversion current value is that when the current of the charger is less than the value, the next stage is carried out after delaying for a certain time;
stage time: controlling the time of the stage by the value, wherein the time is changed to the next stage after the first stage, if the time is set to be 0, the time of the stage is 0, and the next stage is directly changed to; if set to 0xffff (eg:2bytes maximum) indicates that the phase time is infinite.
