Control method for prolonging service life of super-capacitor module
A supercapacitor module, life-extending technology, applied in the arrangement of multiple synchronous batteries, current collectors, electric vehicles, etc., can solve the problem of reducing the number of times the voltage difference is fully charged, affecting the service life of the supercapacitor module, and a single control method, etc. problem, to avoid the pressure difference from becoming larger, to balance the voltage, and to improve the life of the module.

Embodiment 1
[0029] Step 1: Basic processing of equipment and related self-inspection: Before the equipment components are formally installed and controlled, measure, observe and determine the actual physical quantities such as the voltage and current of each actual capacitor, and keep records of the relevant physical quantities in time;
[0030] Step 2: Passive voltage equalization adjustment: Screen the capacitors, and select capacitors with equal voltages during constant current charging to form the relevant modules. The leakage current is fully monitored, and the measured value at each time point is fully recorded;
[0031] Step 3: Active voltage equalization adjustment: connect a voltage equalization circuit in parallel across each capacitor that constitutes the capacitor module, use a voltage comparator, the setting value of the voltage comparator is 2.5V, when the voltage of the capacitor is lower than the set value value, the discharge circuit does not work, and when the voltage of...
