A “charging unit” is a device used to put energy into an energy storage device such as, but not restricted to a secondary electrochemical cell by forcing an electric current through it. The charge current depends upon the technology and capacity of the device being charged.
In certain embodiments is provided a charging unit that works by supplying a constant DC or pulsed DC power source to an energy storage device that is being charged. In some embodiments the charging unit does not alter its output based on time or the extent of charge present in the energy storage device. In certain embodiments is provided an AC-powered charging unit. In an embodiment, the AC-powered charging unit has a ripple current that is under 5 amps.
In certain embodiments is provided a charging unit that is a trickle charging unit. Trickle charging means charging a rechargeable energy storage device at a similar rate as its self-discharging rate, thus maintaining the device at a substantially charged state. Some rechargeable electrochemical cells such as, but not restricted to nickel-cadmium cells or nickel metal hydride cells, have a moderate rate of self-discharge, meaning they gradually lose their charge even if they are not used in a device. In certain embodiments, the trickle charging unit also comprises a regulator to ensure that the charge rate is not greater than the level of self-discharge in order to prevent overcharging and possible damage or leakage.
In certain embodiments is provided a charging unit that is a float charging unit which is a trickle charging unit with circuitry to prevent overcharging. In certain embodiments, the float charging unit senses when the energy storage device voltage is at the appropriate float level and temporarily ceases charging; it maintains the charge current at zero or a very minimal level until it senses that the output voltage from the energy storage device has fallen, and then resumes charging.
In certain embodiments, the charging unit described herein further comprises a timer, which terminates the charging after a pre-determined time. In certain embodiments is provided a “smart charging unit” for use with a “smart energy storage device.” In certain embodiments, a smart energy storage device is one comprising an electronic device or “chip” that can communicate with a smart charging unit about the energy storage device characteristics and condition. A smart energy storage device generally requires a smart charging unit it can communicate with. A smart charging unit is defined as a charging unit that can respond to the condition of an energy storage device, and modify its charging actions accordingly. Some smart charging are designed to transform smart energy storage devices from a substantially uncharged state to a substantially charged state. Some smart charging units are designed to transform from a substantially uncharged state to a substantially charged state, any energy storage device that lacks internal electronic circuitry. The output current of a smart charging unit depends upon the state of the energy storage device. Charging is terminated when a combination of the voltage, temperature and/or time indicates that the energy storage device is fully transformed to a charged state.
In certain embodiments, the charging unit is a ‘just-in-time’ charging unit. In a further embodiment, a just-in-time charging unit is designed to transform energy storage devices when needed so as to minimize excess charging of the energy storage device. In certain embodiments, a just-in-time charging unit does not transform energy storage devices before it is needed to do so, as determined by a processing device. In some embodiments, the need to transform energy storage devices is determined by the processing device based on the inventory or needs of a recipient user.
In certain embodiments, for Ni—Cd and NiMH electrochemical cells, the voltage across the cell increases slowly during the charging process, until the cell is fully transformed. After that, the voltage decreases, this in some embodiments indicates to a charging unit that the electrochemical cell is fully transformed to a substantially charged state. Such charging units are ΔV, “delta-V,” or sometimes “delta peak”, charging units.
In certain embodiments, the charging unit is a fast charging unit. In some embodiments, the fast charging unit makes use of control circuitry in the energy storage devices being charged to rapidly charge said storage devices without damage. In certain embodiments, the charging units have a cooling fan to help keep the temperature of the cells under control.
In certain embodiments, the charging unit uses pulse technology in which a series of voltage or current pulses is fed to the energy storage device. The DC pulses have a strictly controlled rise time, pulse width, pulse repetition rate (frequency) and amplitude. In certain embodiments, the charging units use pulses to check the current state of the storage device when first connected, and then use constant current charging during fast charging, then use pulse charging as a kind of trickle charging to maintain the charge. Some charging units use “negative pulse charging”, also called “reflex charging” or “burp charging”. Such charging units use both positive and brief negative current pulses. Some charging units are constant current charging units. In certain embodiments of constant-current charging units, the charging unit supplies a relatively uniform current, regardless of the temperature and the extent to which energy storage devices are transformed to a substantially charged state.
In certain embodiments, the charging unit is an inductive charging unit that uses electromagnetic field to transfer energy to at least one energy storage device. The charging unit sends energy through inductive coupling to a receptacle which stores the energy in the energy storage devices. In certain embodiments, the receptacle is a removable receptacle that is detachable from a mailer useful to transport said energy storage devices. In certain embodiments is a charging unit as described herein, wherein the capacity of said unit can be expanded by modularly attaching additional receptacles that can contain a plurality of energy storage devices that are transformed to a substantially charged state when connected to the charging unit by means of the receptacle. In certain embodiments, the modules are detachable receptacles that can be placed in a mailer for transporting energy storage devices.
In certain embodiments, the charging unit is a solar charging unit that converts light energy into electricity. In certain embodiments, solar charging units are used for trickle charging. In certain embodiments, solar charging units are used to completely transform the energy storage device from a substantially uncharged state to a substantially charged state. In certain embodiments, the charging unit comprises turbines that convert kinetic energy into mechanical energy which is used to produce electricity. In certain embodiments, the turbines use kinetic energy from the wind. In some embodiments, the turbines use kinetic energy from sea-waves. In an embodiment, the electricity provided by the charging unit to the energy storage device is obtained from a hydroelectric or wind source.

In an embodiment is a charging unit that can simultaneously charge at least 20 energy storage devices. In certain embodiments are charging units that can simultaneously charge at least 50 energy storage devices.

In certain embodiments, at least one charging unit is contained within a distribution unit described herein.
