Abstract

A charging and discharging control circuit for a super-capacitor and an energy storage unit, in particular refers to a charging and discharging control circuit both having a cascade charging control mode, discharging control mode, and recharging control mode switching function, and a parallel type charging and discharging control mode switching function. The charging and discharging control circuit mainly includes at least one power source, at least one super-capacitor, a charging and discharging control circuit, and at least one energy storage unit; wherein the charging and discharging control circuit comprises a control unit, at least one path switching unit, a supercapacitor state sensing circuit and a storage unit condition sensing circuit; and the path switching unit comprises at least one common connection terminal, at least one charging path connecting terminal and at least one discharging path connecting terminal. The control circuit has switchable functions of protecting the charging and power suppling in parallel .

Description

technical field [0001] The invention relates to a charging and discharging control circuit for a supercapacitor and an energy storage unit, in particular to a switching function of a cascade charging control mode, a discharge control mode and a recharging control mode, and a parallel charging control circuit. The control circuit of the discharge control mode switching function. Background technique [0002] The so-called super capacitor is characterized in that in addition to its large capacity, it can temporarily store a considerable amount of electrical energy. It is not only reversible, but also can store and release energy in a short time. It is a high power density, energy density In recent years, a new type of hybrid supercapacitor battery has both the functions and characteristics of batteries; compared with supercapacitors, general energy storage units cannot withstand high-current charging in a short period of time. The release of high-current electric energy, and ...
