 2.charger for lipo battery







AVL ( Automatic Vehicle Location Device ) is a powerful concept for managing fleets of vehicles, as service vehicles, emergency vehicles, and especially precious construction equipment, also public transport vehicles. It is also used to track mobile assets, such as non wheeled construction equipment, non motorized trailers, and mobile power generators.

Asset Tracking refers to tracking the valued assets. RFID-based and GPS asset tracking technology have been using to manage the movements of commercial fleets, cargo shipped by air, land or sea.  At present, the tracking system is typically powered by a self-contained battery.

There are two battery powered solutions: one is rechargeable Li-ion / Li-polymer batteries, the other is non rechargeable lithium thionyl chloride batteries.

Which kind of batteries for you products, it is greatly decide by environments of your products are used and your products assets which kind of fields. Usually, high capacity rechargeable lithium battery can work 4-6 months after charging. But the cycle life is over 500 times.

1.May I charge Primary Lithium batteries?
When a Primary Lithium battery is charged, gas is generated inside the battery and can result in swelling, heat generation, leakage bursting and fire.


2.Can I force-discharge lithium batteries?
When batteries are force-discharged with an external power source, the voltage drops to under 0 volts (which is called voltage reversal ) and internal gas is generated. This can lead to swelling, heat generation, leakage, rupture or fire.


3.Can I use Lithium batteries mixing with other battery types?
If different types of batteries are used together, or new batteries are used with old ones, the difference in characteristics of voltage, capacity, etc., may cause over-discharge of the battery which is exhausted first, leading to swelling, bursting or fire.


4.Where should lithium batteries be stored?
Lithium batteries should be stored in a cool, dry place that is not exposed to direct sunlight and has minimal temperature variation. Storage in areas subject to high temperature or humidity may cause deterioration in battery quality and durability. To avoid short circuiting batteries during storage, be sure that the positive and negative terminals do not come into contact with each other.


5.What is a short circuit?
If the positive and negative terminals of a battery come into contact with each other or with a conductive metallic object, this can cause a short circuit, which generates heat. If cells or batteries are stacked on top of each other or mixed, the resulting short circuit can lead to heat generation, leakage, rupture, and possibly fire.

7.Difference of rechargeable lithium battery


Lithium-ion ( Li-ion or LiIon ) Battery

Lithium-ion ( Li-ion ) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge, and reversely when charging. Different types of lithium-ion batteries use different chemistry and have different performance, cost, and safety characteristics.

Lithium-ion batteries are common in consumer electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defence, automotive, and aerospace applications due to their high energy density. 

Lithium-ion Polymer ( Li-Po or LiPo ) Battery

Lithium-ion polymer batteries are technological evolution from lithium-ion batteries. The primary difference is that the lithium-salt electrolyte is not held in an organic solvent but in a solid polymer composite such as polyethylene oxide or polyacrylonitrile.
The advantages of lithium-ion polymer over the lithium-ion design include adaptability to a wide variety of packaging shapes and ruggedness. 

Lithium Iron Phosphate Li-FePO4 Battery

The latest innovation in Li-FePO4 offer the energy density, weight and size benefits of Li-ion but are proven to be far safer in critical situations; coupled with a working life of 1,000 charging cycles, double that of other battery types.
