6 FAQs about [Battery and charging circuit]
How complex is a battery charging system?
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.
How do you charge a battery?
Charging batteries is simple (in theory) – put a voltage across the terminals and the battery charges. If safe charging, fast charging and/or maximum battery life are important, that’s when things get complicated.
Can you build your own battery charger circuitry?
Well, here’s the good news-you can build your very own battery charger circuitry that’s intelligent, efficient, and automatic. Using an LM317 voltage regulator and a relay, this circuit not only charges your batteries but also stops charging once they’re full. Think of it as a responsible babysitter for your batteries!
How many batteries can be charged in a single Charger?
For more critical applications, one or more can be combined in a single charger. Peak voltage detection is used in the constant current regulator (CCR) battery charging circuit shown below. Using a peak voltage detection point of 1.5 V/cell will result in charging to about 97% of full capacity for NiMH and NiCd batteries.
How does a battery charge cycle work?
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.
How does a battery charger work?
The charger senses this and sources maximum current to try to force the battery voltage up. During the current limit phase, the charger must limit the current to the maximum allowed by the manufacturer (shown as 1c here) to prevent damaging the batteries.
