Traction Battery

Traction Battery? ​In the second in his interactive series Dr Mike explains what features are required to make 2V lead acid traction battery cells for fork lift trucks. He also gives valuable advice on how to choose the best fork lift truck battery for your particular requirements. Forklift truck What is a traction battery? According to European standard IEC 60254 – 1 lead acid traction batteries are used as power sources for electric propulsion in applications which include road vehicles, locomotives, industrial trucks [...]

Sizing of batteries

Introduction ​ The use of solar off-grid energy supply is becoming increasingly popular for domestic, industrial and municipal applications. Due to the variable nature of renewable energy sources, many of the installations include an energy storage system to enable supply for peak demands and when energy generation is limited. There are alternative storage technologies but the method of calculating the size of the lead acid battery required is common to all chemistries. To ensure a system that satisfies the [...]

PVC Battery Separators

PVC Battery Separators -An overview of characteristics, manufacture & test methods. PVC battery separators are microporous diaphragms placed between the negative and positive plates of lead acid batteries to prevent any contact between them to avoid internal short circuit but at the same time allow free circulation of the electrolyte. This kind of Separators has a maximum pore size of less than 50 micron meter and lower electrical resistance of less than 0.16 ohm / cm sq. PVC separators are uniform [...]

What is a VRLA battery?

A Valve Regulated Lead Acid (VRLA) battery is simply a lead acid battery in which the electrolyte has been immobilised in order to recombine hydrogen and oxygen. It has a sealed construction with pressure release valves to prevent gases from escaping, It is this which gives it its name. Because the electrolyte is no longer in a fluid state, due to either being mixed with silica powder to form a gel or absorbed into a finely textured glass mat, [...]

What is a VRLA Battery?

What is a VRLA Battery? One of the major drawbacks with charging a flooded lead acid battery is the breakdown and loss of water through hydrogen and oxygen release. This has more than one negative implication for the safe use and operation of all types of lead acid batteries. The release of potentially explosive mixtures of hydrogen and oxygen in confined spaces and the constant topping up of batteries or cells with distilled water are costly problems for the battery [...]
