The Fundamentals of Capacitors in AC Circuits
As with inductors, capacitors charge and discharge, and the energy stored in the capacitor in the one-quarter cycle is returned in the next quarter cycle, so the average power in a purely capacitive circuit is zero. In Figure 1, the shaded power waveform results from multiplying the instantaneous voltage and current values.
voltage
$begingroup$ You have to consider how much current your power supply can handle, and certainly the ripple current and voltage rating of the capacitor. If your supply along with it''s output impedance, layout impedance and the ESR of the capacitor gives you a charging current that''s acceptable then you don''t need a resistor in series.

It can also utilize the charging during the low power hours to reduce the cost, while deep charging improves the battery charging and discharging efficiency and prolongs the life of the battery equipment.
How do you know if an amp needs new capacitors?
Generally its only electrolytic capacitors that need replacing, the most critical being the ones serving as filters in the power supply. Occasionally resistors that are stressed (like ones near the power tubes) can fail, and in some designs its a good idea to replace some of these with higher tolerance ones before they fail. Some would say that ...
Pile on to a charger my EV needs power
in 2015 to 5 million in 2020. Along with this comes the rapid development of charging stations and charging piles. A charging pile is similar to a charging station where AC power is converted to DC power to charge the battery of the vehicle. However, a charging pile can just be an AC to AC conversion with more focus on diagnostics and monitoring.

Inverter Capacitor Pre-charging | DIY Solar Power Forum
here is the catch... we really do not need to fully charge the cap!! (even the bulb goes out before the cap is fully charged)... basically the capacitor will charge to 63%V after just 1 "time cycle"...which is R*C, in this case 40seconds the current inrush will be cut to 37% of max in just 1 time cycle!
Why do charges enter the capacitor in the first place?
$begingroup$ Actually, I think the OP knows that, he''s asking why the charges want to approach the capacitor in the first place. Normal charge flow happens because of a train-like effect, with a source and sink of electrons. The OP doesn''t see how this works with capacitors, AFAICT. $endgroup$
