![]() ![]() The C-rate is never negative, so whether it describes a charging or discharging process depends on the context.įor example, for a battery with a capacity of 500 mAh, a discharge rate of 5000 mA (i.e., 5 A) corresponds to a C-rate of 10C, meaning that such a current can discharge 10 such batteries in one hour. While rarely stated explicitly, the unit of the C-rate is h −1, equivalent to stating the battery's capacity to store an electrical charge in unit hour times current in the same unit as the charge or discharge current. The C-rate is defined as the charge or discharge current divided by the battery's capacity to store an electrical charge. 2.11 Universal battery charger–analyzerĬharge and discharge rates are often given as C or C-rate, which is a measure of the rate at which a battery is charged or discharged relative to its capacity.For public access, installation of such chargers and the distribution support for them is an issue in the proposed adoption of electric cars. Electric vehicles ideally need high-rate chargers. Such batteries require active monitoring of the battery to protect it from overcharging. High-rate chargers may restore most capacity much faster, but high rate chargers can be more than some battery types can tolerate. Slow battery chargers may take several hours to complete a charge. Lithium-ion batteries cannot handle indefinite trickle charging. Some battery types cannot tolerate trickle charging attempts to do so may result in damage. Ī trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.Ĭhargers may elevate the output voltage proportionally with current to compensate for impedance in the wires. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. Other battery types use a timer to cut off when charging should be complete. Simple chargers of this type must be manually disconnected at the end of the charge cycle. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. The charging protocol (how much voltage or current for how long, and what to do when charging is complete) depends on the size and type of the battery being charged. Phoenix Inverter VE.For other senses of this term, see AC adapter.Ī battery charger, or recharger, is a device that stores energy in a battery by running an electric current through it.Phoenix Inverter Compact 1200VA – 2000VA.Suitable for use on all vehicles and boats.Sharpens battery response to accept faster charge.Battery to blow sulphation off the plates.This is not a battery charger and it cannot actually charge your batteries it is a de-sulphation device. ![]() #Battery pulse proThis device is not required if you have a Pro Digital battery charger or any other advanced Sterling charging product connected to your batteries as they have a de-sulphation cycle built into their software program. The Pro Pulse should be fitted to any battery bank to ensure that sulphation is not only prevented but also reversed and so prolong the life and performance of the battery bank. The solution is to remove this sulphation and expose the plate to the battery process again. Sulphation acts like a waterproof coating over the plates preventing the plate area effected being active and contributing to reduction in the battery cell performance. If you have been replacing batteries because they are not holding their charge then in most cases the battery is, in fact, in good condition except the plates are sulphated. ![]() #Battery pulse freeThis unit reverse feeds a small electrical pulse back into the battery which prevents and also reverses sulphation on the battery plates.īy keeping the plates clean and free from sulphation the battery stays fresh and responsive to charging and discharging. ![]() The Pro Pulse is designed to connect to a 12V battery bank. ![]()
