  • Solar Charge Controller

    Solar charge controller is a device that in charge of controlling the energy going into the battery bank directly from the sun. This device guarantees that the  energy in the batteries are not loss during the day and that the energy doesn’t run in reverse. Some solar charge controller are accessible of extra capacities, such as lighting and load detector, however dealing with the energy is its major focus.

    A solar charge controller is accessible in two advancements, PWM and MPPT. How they act in a framework is totally different from one another. A MPPT charge controller is more costly than a PWM charge controller, and it is regularly justified, despite all the trouble to pay the additional cash.

    Charging of battery bank – changes the measure of intensity set to the batteries dependent on its charge level, for more beneficial batteries.

    It turns around power security – prevents the sun oriented boards from depleting the batteries around evening time when there is no force originating from the sunlight based boards.

    Low voltage– this kills the joined loads when the battery is low and enables it when the battery is energized back.

    Lighting control – turns appended light on and off dependent on sunset and day break. Numerous controllers are configurable, permitting settings for a couple of hours or throughout the night, or some place in the middle.

    However, the display may show a voltage of battery bank, condition of charge, amps rolling in from sunlight based board.

  • Zinc-Carbon Battery

    A zinc-carbon battery is a dry cell primary battery that delivers about 1.5V of DC from the electrochemical reaction between Zn (Zinc) and MnO2. A carbon rod collects the current from the MnO2 (manganese(iv)oxide) electrode, as its name implies.

    A dry cell is usually made from zinc, which serves as the anode with a negative electrical polarity, while the inert carbon rod serves as the positive electrical pole cathode. These batteries made portable devices such as the flashlight possible because of its ability to function in a diverse set of these devices besides the fact that they were the first set of commercial dry batteries. Its formation can be seen below:

    Zn + 2 Cl → ZnCl2 + 2 e

    2 MnO2 + 2 NH4Cl + H2O + 2 e → Mn2O3 + 2 NH4OH + 2 Cl

    Zn + 2 MnO2 + 2 NH4Cl + H2O → ZnCl2 + Mn2O3 + 2 NH4O

    Zn + 2 Cl → ZnCl2 + 2 e

    2 MnO2 + ZnCl2 + H2O + 2 e → Mn2O3 + Zn(OH)2 + 2 Cl

    Zn + 2 MnO2 + H2O → Mn2O3 + Zn(OH)2

    The zinc-carbon battery is to be stored at room temperature as recommended by manufacturers. Storing them at a temperature higher than the recommended temperature would thwart, terminate and, shorten the shelf life of the battery. It is safe to store it below room temperature, that is, freezing, but before use, it must be unfrozen to enable it to function effectively and prolong its shelf life.

    The zinc-carbon cells have a short shelf life laying the fact that the zinc is constantly attacked by ammonium chloride. And as it is being used it becomes thinner and thinner until its no longer functional for use.

  • Zinc Air Battery

    Zinc air batteries is a metal-air battery powered by oxidizing zinc and oxygen from the air. These batteries have high energy densities and are relatively cheap to produce/manufacture. It can be used in hearing aids, film cameras, and electric car induction. A zinc air battery has a high amount of energy and weight more than other types of batteries since atmospheric air is one of its reactants.

    Zinc air battery has a long shelf life if sealed to keep air out; even the smallest form of this battery, button battery can be stored for up to 3 years at room temperature if its seal is not removed. The shelf life of a zinc air battery is a function of its interaction with its environment.

    The electrolyte loses water faster in conditions of high temperature and low humidity because the potassium hydroxide electrolyte is capable of absorbing moisture from the air and dissolving it. In very humid conditions excess water accumulates in the cell, flooding the cathode and destroying its active properties.

    Potassium hydroxide also reacts with atmospheric carbon(iv)oxide; the formation of the carbonate reduces electrolyte conductivity. These batteries have high self-discharge once opened to air; the cell’s capacity is intended to be used within a few weeks. The formula for the formation of this battery is:

    Anode: Zn + 4OH → Zn(OH)42− + 2e (E0 = -1.25 V)

    Fluid: Zn(OH)42− → ZnO + H2O + 2OH

    Cathode: 1/2 O2 + H2O + 2e → 2OH (E0 = 0.34 V pH=11)

    Overall: 2Zn + O2 → 2ZnO (E0 = 1.59 V)

    The zinc air battery is of two types, either primary (non-rechargeable) or secondary (rechargeable)

  • Wireless Battery Charger

    Wireless battery charger makes use of an inductive or magnetic field between two objects which are typically coils to transfer enough energy from one to another for use. The energy is transferred from the energy source to the receiver where it is typically used to charge the battery in the device like smartphones, tablets, laptops.

    Wireless battery charger technology has been around for more than 100 years, but its impact on devices such as Apple’s new iPhone line has restored it to a brand new and improved technology. It works through a medium of relying on an electromagnetic field between two copper coil, which greatly limits the distance between the receiver’s device and a charging port. That’s the type of charging Apple has built into the iPhone 8 and the iPhone X.

    Here are positioned the three types of wireless battery charger which are the non-radiative charger, trickle charger, electromagnetic resonant charger.

    The wireless battery charger works with some basic charge standards like the QI. Wireless charging standard uses a power transmitter pad that is with a similar character to the charger that would be used in a normal wired system, and a compatible wireless power receiver that is located in the device to be charged.

    There are basically two types of wireless battery charger categories namely the low power category and the medium battery category, and as it comes with categories it also has basically two Elements which are base stations and mobile devices. To achieve this power must be very high.

  • USB Battery Pack

    The USB battery pack, also known as the Power Bank can be defined as a portable battery pack that uses circuitry to control any power in and power out. They have the ability to charge up using a USB charger when power is available and then used to charge battery-powered items like mobile phones and other devices that would normally use a USB charger.

    They are used for providing portable power to charge battery-powered items like mobile phones and other similar items that have a USB interface.

    [home]

    There are two different types of USB Battery Pack, they are the universal power bank and the solar power bank. The universal power bank is the normal USB Battery Pack portable chargers available in the stores and online. They are charged from the normal USB sources like USB chargers.

    The solar power bank, as the name implies is capable of using sunlight to charge up since they have photovoltaic panels. The photovoltaic panels are only able to trickle-charge the internal battery when placed in sunlight because the solar cells are relatively small, but nevertheless, this is a very useful function.

    A good USB battery pack is capable of holding a charge for up to 6 months with only a small loss of charge, but lower quality ones may only be able to retain a useful charge for about a month. The USB battery packs are for room temperature, but storing them outside the required room temperatures may considerably reduce their performance.

  • USB Battery Charger

    USB devices that need more power than this are called high power devices (instead of low power).  The maximum load that is requested for USB2.0 is 500mA and USB3.0 is 900mA.

    The USB Battery Charger Specification gives optional new power modes. A host or hub port that supports charging can only supply up to 1.5 A when communicating at low speed or full speed, or a maximum of 900 mA when communicating at high speed, and as much current as the connector will safely handle when no communication is taking place.

    Most people use USB charger for multiple devices not knowing if it is good or bad this will show the required answer. While you are thinking that all mini USB cables are of equal size, just because a charger fits your device doesn’t really means you should use it.

    As there are different types of smartphones and tablets, these also have different voltage required for successful charging; when there are too many volts from the charger the gadget fries which may cause a fault to the phones charging port which will be too few and the device will take forever to charge. With this point, it is noted that it is not right to share USB chargers.

    Most of us out of lack of information charge our phone with USB connected to laptops well it is not safe because it exposes battery chemicals to unsafe, secure and fast charges, lowing the batteries voltage and damaging the phone’s cell.
