The direction of current through the battery determines whether it is charging or discharging. The battery is trying to push current in a particular direction. If the current flows in that direction, the battery is discharging. If the current flows in the other direction, the battery is charging. It is a little bit like a spring or a clockwork toy.

During the night (during the period of low solar irradiation), energy is supplied to the motor from the battery. First, I decided to look for diagrams that would implement this electrical system. I found just such a circuit, but in it the battery is, as it were, separated from the battery and does not feed on it.
The CDI ignition circuit produces a spark from an ignition coil by discharging a capacitor across the primary of the coil. A 2uF capacitor is charged to about 340 volts and the discharge is controlled by an SCR. A Schmitt trigger oscillator (74C14) and MOSFET (IRF510) are used to drive the low voltage side of a small (120/12 volt) power transformer and a voltage doubler

The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and charger circuits for use with Nickel-Cadmium (Ni-Cd), Nickel Metal-Hydride (Ni-MH), and Lithium-Ion (Li-Ion) batteries.
High-Current Battery Discharger If you have a motley collection of 12V batteries in varying states of health, this simple circuit will allow you to easily check their capacity. It's basically a high-current discharge load which is controlled by the NiCd Discharger.
The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.
Both Ni-Cd and Ni-MH are charged from a constant current source charger, whose cur-rent specification depends on the A-hr rating of the cell. For example, a typical battery for a full-size camcorder would be a 12V/2.2A-hr Ni-Cd battery pack. A recharge time of 1 hour requires a charge current of about 1.2c, which is 2.6A for this battery.
In the realm of battery charging, charging methods are usually separated into two gen-eral categories: Fast charge is typically a system that can recharge a battery in about one or two hours, while slow charge usually refers to an overnight recharge (or longer).
