Lithium-ion Batteries the next generation of Solar Batteries
Lithium ion batteries are very different to conventional deep cycle batteries and have created a revolution in both on and off the grid-connected residential energy storage options. Check out our home battery storage options and find out how you can get off the grid electricity and view our range of next-generation home battery systems.
Specific Gravity SG - The ratio of the weight of a solution compared with the weight of an equal volume of water at a specified temperature. It is used to determine the charge condition in lead acid batteries.
Starting batteries, which are also known as cranking batteries, are designed to discharge a large amount of energy for a short period. This makes them ideal for starting engines, such as an automotive engine or an inboard or outboard marine engine.
Ohmic loss - The voltage drop across the cell during passage of current due to the internal resistance of the cell. Also known as IR loss or IR drop.
This loss of charge capacity represents the loss of active chemicals per cycle, or the creation of unwanted chemical products and the consequent increase in the thickness of the SEI layer per cycle and can be considered as the degradation factor of the cell
Active material - The chemically reactive materials in an energy cell which react with each other converting from one chemical composition to another while generating electrical energy or accepting electric current from an external circuit.
For lead acid batteries the rated capacity (. the number of AH stamped on the side of the battery) is typically given for a 75 hour discharge rate. If you are discharging at a slow rate you will get the rated number of amp-hours out of them. However, at high discharge rates the capacity falls steeply. A rule of thumb is that for a 6 hour discharge rate (. drawing 65 amps from a 65 amp hour battery, or 6C) you will only get half of the rated capacity (or 5 amp-hours from a 65 amp-hour battery). Charts that detail this effect for different discharge rate can be used for greater accuracy. For example the data sheets listed in http:///
Linear charger - Charger which uses a series regulator. The simplest and cheapest type but less efficient than a Switch mode charger.
Formation is essentially the first charge carried out at the cell manufacturer's plant under very carefully controlled conditions of current, temperature and duration to create the desired microstructure of the components and the contact between them.
C C Programming Language - The preferred programming language for embedded software used in many battery management applications. Robust, fast and powerful, it allows low level access to information and commands while still retaining the portability and syntax of a high level language.
