  • Industry 4.0 and the fourth industrial revolution (4IR)

    As a reminder the classic view of these four industrial revolutions, as Industry 4.0 became increasingly popular, was:The first industrial revolution, which REALLY was a revolution, and, among others thanks to invention of steam machines, the usage of water and steam power and all sorts of other machines, would lead to the industrial transformation of society with trains, mechanization of manufacturing and loads of smog.The second industrial revolution is typically seen as the period where electricity and new manufacturing ‘inventions’ which it enabled, such as the assembly line, led to the area of mass production and to some extent to automation.The third industrial revolution had everything to do with the rise of computers, computer networks (WAN, LAN, MAN,…), the rise of robotics in manufacturing, connectivity and obviously the birth of the Internet, that big game changer in the ways information is handled and shared, and the evolutions to e-anything versions of previously brick and mortar environments only, with far more automation.In the fourth industrial revolution we move from ‘just’ the Internet and the client-server model to ubiquitous mobility, the bridging of digital and physical environments (in manufacturing referred to as Cyber Physical Systems), the convergence of IT and OT, and all the previously mentioned technologies (Internet of Things, Big Data, cloud, etc.) with additional accelerators such as advanced robotics and AI/cognitive which enable Industry 4.0 with automation and optimization in entirely new ways that lead to ample opportunities to innovate and truly fully automate and bring the industry to the next level.Hebei Xindongli New Energy Science and Technology Co.,Ltd specialize in producing many kinds of lithium batteries mainly used for these applications, boats and busespowered by batteries, camper vans,RV,AGV,home photovoltaic power plants, public lighting systems, solar system tec.

  • Lithium Ion Battery Maintenance Guidelines

    Do not leave batteries unused for extended periods of time, either in the product or in storage. When a battery has been unused for 6 months, check the charge status and charge or dispose of the battery as appropriate.The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Use a two to three year life expectancy for batteries that do not run through complete charge cycles.Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. Routinely check the battery’s charge status. The product user manual typically includes information on how to check battery status, as well as battery charging instructions.

  • What is the difference between a gel battery and a lead-acid battery?

    When Gel batteries were introduced into the industry, they were roughly 4 times the cost of a lead acid battery. As higher volumes were produced for the Gel batteries, they rapidly reduced in price and increased in quality.Today, a gel battery will cost roughly 30% more than that of a wet lead acid battery with none of the headaches, maintenance, or charging issues. As a result, gel batteries are now more commonly used in floor scrubbers and floor sweepers.  A common question asked is what are the main differences between these batteries so to help you out, below highlights the key advantages and disadvantages of Gel and Lead batteries. Gel BatteriesAdvantages · Sealed· Spill-proof· Maintenance free· Classified as non-hazardous goods for air, rail & road transportation· Extremely low self-discharge rate· No gassing· Withstand a wide range of temperatures  · Withstand shock & vibration better than any other battery· No terminal corrosion· MSDS sheets not required· Can be installed near sensitive electronic equipment · Excellent deep cycle performance Disadvantages · More expensive than lead acid· Sensitive to overcharging (although this is not an issue with a correctly specified SMART charger) Lead acid batteryAdvantages· Relatively inexpensive· Widely available· Good size to capacity ratio · Good deep cycle performanceDisadvantages· Require strict maintenance· Require ventilated rooms for recharging· Suffer from terminal corrosion· can leak is casing is cracked causing hazardous spill· Require rubber gloves & goggles when maintaining· Vent substantial quantities on hydrogen & oxygen gasses as well as other toxins · Will quickly sulphate if left discharged for any period of time· Are easily damaged if over-charged·  Have high self-discharge rate· Are classified as hazardous goods for transportation

  • Cell Options for UAV Batteries

    Li-ion cells come in three basic form factors: cylindrical, prismatic (rectangular brick shape), and flat Lithium polymer cells. The most commonly used Li-ion cell is the cylindrical 18650 cell, which utilizes a steel or aluminum can. Prismatic or brick-shaped cells are available in a myriad of rectangular sizes, and are packaged in a metal can. Lithium Polymer (Li-Po) cells, sometimes called laminate cells, can be encased in flexible aluminum foil laminate pouches that are just 0.1 mm thick, versus the 0.25 to 0.4 mm thick metal cans traditionally used with cylindrical or prismatic cells. Because of the lighter packaging of the Li-Po cell, it is the cell of choice for most UAV manufacturers. The biggest advantage of Li-Po cells is the variety of available sizes. Because Li-Po cells are often custom-sized and the manufacturing process is easily configurable, these cells are available in a myriad of sizes and a variety of shapes. Figure 3 illustrates the construction of a Li-Po cell. They are assembled by stacking electrode and electrolyte materials in layers, rather than winding them around a mandrill and then inserting them into a hard metal can, as with other cylindrical or prismatic cells. Li-Po cell capacities range from 50 mAhr or smaller for applications like smartwatches to 50 Ahr or more for a cell tailored to light electric vehicle use.

  • Simple Guidelines when Buying a lithium battery Charger

    · Charging a battery is most effective when its state-of-charge (SoC) is low. Charge acceptance decreases when the battery reaches a SoC of 70% and higher. A fully charged battery can no longer convert electric energy into chemical energy and charge must be lowered to trickle or terminated.· Filling a battery beyond full state-of-charge turns excess energy into heat and gas. With Li-ion, this can result in a deposit of unwanted materials. Prolonged over-charge causes permanent damage.· Use the correct charger for the intended battery chemistry. Most chargers serve one chemistry only. Make sure that the battery voltage agrees with the charger. Do not charge if different.· The Ah rating of a battery can be marginally different than specified. Charging a larger battery will take a bit longer than a smaller pack and vice versa. Do not charge if the Ah rating deviates too much (more than 25 percent).· A high-wattage charger shortens the charge time but there are limitations as to how fast a battery can be charged. Ultra fast charging causes stress.· A lead acid charger should switch to float charge when fully saturated; a nickel-based charger must switch to trickle charge when full. Li-ion battery cannot absorb overcharge and receives no trickle charge.  Trickle charge and float charges compensate for the losses incurred by self-discharge. · Chargers should have a temperature override to end charge on a faulty battery.· Observe charge temperature. Lead acid batteries should stay lukewarm to the touch; nickel-based batteries will get warm towards the end of charge but must cool down on “ready.” Li-ion battery should not rise more than 10ºC (18ºF) above ambient when reaching full charge.· Check battery temperature when using a low-cost charger. Remove battery when warm.· Charge at room temperature. Charge acceptance drops when cold. Li-ion cannot be charged below freezing.
