How do you charge a super capacitor?
Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
What is a supercapacitor Charger?
A supercapacitor is the right choice for applications where rapid charging and discharging is needed such as an automatic aisle carrier in a modern warehouse. The MAX17701 is an ideal controller for fast supercapacitor charger designs.
What is a supercapacitor in electric vehicle?
So, here we are using a supercapacitor that charges and discharges in less time. The design of electric vehicle will remain the same, but we are adding a super capacitor bank inside the EV for charging the battery. The super capacitor is supplied from through the off-board charger with the plug-in configuration.
Which supercapacitor charger is best?
The MAX17701 is the perfect choice for a fast supercapacitor charger in this application. Amongst many other features, the MAX17701 also provides a safety timer (TMR) feature to set the maximum-allowed constant current (CC) mode charging time.
Why does a super capacitor charge at a constant voltage?
Eventually, the super capacitor voltage, and therefore the charging circuit’s operating efficiency, increases so the capacitor charges at the desired constant (fast or max) charge current, ICHG, until it reaches and remains at constant voltage (CV) regulation voltage, VREG.
Why does a SuperCap Charger need a reverse current blocking capability?
Similarly, the SuperCap charger circuit must have reverse current blocking capability to avoid draining the super capacitor. When the main power restores, it is important to limit the charging (inrush) current for the discharged super capacitor to avoid disturbance on the system voltage.
