First Lithium Ion battery for Motive Power

The Hawker XFC-Li is the first motive power battery from EnerSys to utilise advanced lithium-ion technology. It is a 24V battery with 38Ah capacity that incorporates cells with a lithium iron phosphate (LiFePO4) cathode and graphite anode with an inherently safe lithium-ion electrolyte. This delivers significant benefits compared with conventional units including greater power density, longer pack life and excellent performance at low temperatures. The battery can be fully recharged in less than one hour from 80 per cent depth of discharge and short, opportunity charges are readily accepted due to its very low internal resistance.

Each Hawker XFC-Li is equipped with a battery management system (BMS) for continuous monitoring of the individual cells to ensure correct use and safe operation with protection against over temperature, overcharge, over voltage, under voltage and short circuits. The BMS also incorporates cell balancing technology which promotes maximum performance throughout the battery’s service life. An on-board LED provides state of charge data while links with external monitoring and management systems can be enabled by an integrated CAN bus.

The second new battery is a 24V model with 82Ah capacity which is based on the same proven thin plate pure lead (TPPL) technology used in the existing Hawker XFC range. Its blocs incorporate pure lead plates which are much thinner than conventional lead calcium grids. These have lower impedance which enables higher current flows in recharge and discharge modes. The electrolyte is absorbed in a superior quality microporous glass mat separator with high absorption and stability for enhanced cyclic capability. These attributes ensure a full recharge is completed in under three hours from 60 per cent depth of discharge.



The battery pack incorporates a low voltage alarm – LVA. This small electronic device is positioned between the positive and negative cables and warns the operator whenever the battery reaches a specific depth of discharge that a recharge is required. The battery pack also includes a Wi-IQ? monitoring device which stores comprehensive operational records. This information can be transferred to external battery management applications using wireless communications or a USB port for further analysis.

Both models are supplied with a high frequency ups backup power integrated into the top compartment of the battery tray. High frequency charging in inherently more efficient than traditional methods while the charger ensures the correct parameters for rapid recharge and opportunity charging whatever the battery’s state of discharge. By comparison, conventional batteries only provide optimum performance when discharged to a specific level before being fully recharged for 8-12 hours. This often means extra batteries are required to support continuous equipment availability or can lead to interruptions in charging which is potentially damaging to conventional battery technologies.

High-frequency charging also ensures the batteries consume less energy, with resultant lower electricity costs, and have a smaller carbon footprint than conventional units. The batteries are totally maintenance free and require no topping-up with water for low overall cost of ownership while minimum gassing means they can be used in confined spaces and public areas.

Brief Introduction of Continuous Ups Power Backup

What is Ups Power Backup

The whole world unites at a single place Internet. Ranging from small business to the giant multinational companies everyone has their existence in the internet market. It is obvious that to work on the internet you need computer system, laptops etc. Most of the companies use computer systems to perform the work. Computer system being an electronic device relies on electricity. Without electricity one cant work with the computers. This has increased the demand of electricity but the same amount is not supplying to the firms. Uninterrupted Power Supply that ups backup power has resolved this problem by providing regular power supply. This can run the system for fifteen to twenty minutes so that you can save your running data and information and can properly shut down the PC.



Introduction of Ups Power Backup

An online uninterrupted power supply can help even small businesses save a lot of money and time by ensuring that their critical applications stay protected given unprecedented energy and electricity fluctuations. An online UPS system ensures that data stored on the servers is not affected by the constant electricity cuts, spikes etc. It also takes care to protect the device from high and low voltage electricity. The capacity of the UPS systems depends upon the requirements of the device it is connected with. Apart from this there are a number of parameters that needs to consider when purchasing an Online UPS. Below mentioned is a list of few:

Brand

You should purchase only from the reputed manufacturer to be sure about the quality of device. You will also get a warranty of repair or service. There are several renowned manufacturers providing a comprehensive range of UPS as well as HT AVR, Variac, Transformers, and Stabilizers to beat all issues related to the electricity. Servo stabilizer manufacturers are one of them. All the products manufactured by this company are tested under strict quality tests and are ISO certified.

Power Requirement

It is also mandatory to decide that for how much time you want to provide the backup to your devices. It will help you the one which suits best to your requirements.

Cost

When purchasing a UPS dont forget to check about the cost of the product and comparing it with other brands. You need to visit from one shop to other for doing this rather internet has all the information related to it. There are many web portals and websites offering online purchasing of UPS. You can search and check it yourself. When purchasing online UPS or HT AVR remember to check the shipping cost and time it will take to reach up to you.

How to Select UPS Backup Power?

UPS selection and maintenance of UPS backup power

The computer has been widely used in all walks of life. As directly related to the safe operation of computer hardware and software is one of the important factors -- power quality reliability should be considered to the first problem of medium and small enterprises. Along with the computer the birth of ups backup power has now been accepted by the majority of computer users.UPS is mainly used to a single computer, computer network systems or other power electronic device with uninterrupted power supply. At present, UPS is widely used in computer, communications, banking, securities, telecommunications, medical, industrial control and other industries. Many electrical engineering personnel in the configuration of power, tend to focus on uninterruptible power supply (UPS) host performance, ignored the UPS selection of batteries for. Inappropriate matching battery selection tends to cause UPS backup time is insufficient, and the battery cannot discharge accidents, serious impact on the quality of UPS.

The working principle of UPS and types

UPS power is generally made of common power and standby power through the switch combination, between them by a logic circuit to control, to ensure the normal in the power grid blackouts or state, the system can work reliably. When the commercial power is normal, UPS is equivalent to nickel cadmium cell regulated power supply, it will power supply voltage after the computer, at the same time, it also to the UPS battery charging. When electricity is suddenly cut off, UPS immediately to inverter working state, small volume of UPS in general and can continuously supply power 5 ～ 20 min, so can guarantee that the computer system normal exit, make the software and hardware are not subject to loss.


The species of UPS

The UPS classification methods varied, according to the power size can be divided into large and medium-sized mistress power capacity; the output waveform can be divided into square wave, trapezoidal wave or sine wave; according to the input and output can be divided into single phase into single-phase, three-phase to single-phase or three-phase to three-phase; according to the work principle can also be divided into dynamic UPS and static UPS two categories. Dynamic uninterruptible power supply is dependent on inertial flywheel stored energy to maintain the load power supply continuity, the uninterruptible power supply with heavy, large noise, low efficiency, long switching time and other shortcomings, has been replaced by a static uninterruptable power supply. Static UPS to batteries as the energy storage tool, city normal AC power is rectified into a DC electrical and electrical energy stored in the batteries, when the utility power is cut off by the inverter will be stored in the storage battery DC power into AC power to maintain power to the load. According to the different working modes, static UPS can be divided into the backup UPS, on-line UPS, on line interactive UPS and Delta transformation UPS four kind of types.
