SMARTGAUGE ELECTRONICS One of the side effects of diodes is that there is a voltage drop associated with them. This drop is not constant and varies from around 0.6 volts to 1.1 volts depending upon how much current is flowing through them. At very high charge currents the voltage drop can actually be as much as 1.6 volts. The higher the current, the higherthe

A diode drops a voltage of around 0.6 volts at low currents, increasing up to around 1.2 volts at high currents. So if we use a diode at low current, it will drop just about the right voltage.

SMARTGAUGE ELECTRONICS runs the usual equation (T=C/I n) on the discharge rates whereas the second one calculates the run times directly on the specified battery capacity using our modified Peukert's equation (T=C(C/R) n-1 /I n).The only difference in results is the adjusted Peukert Amps. You will notice that the final run times and available capacity are identical in both spreadsheets thus showing that both SMARTGAUGE ELECTRONICS Here is the internal schematic of a standard galvanic isolator. It goes in-line with the earth lead between the shorepower plug on the quayside and the AC electrical system on the boat. Each diode in the isolator will drop around 0.6 volts before it starts to conduct. So 2 in series will require 1.2 volts before any conduction takes place. SMARTGAUGE ELECTRONICS The importance of reducing small loads. The small loads in many installations tend to be ignored on the basis that they don't really make much difference when compared to the effect of the larger loads.

If the timer attempts to fire up the boiler with the isolator switched off, the boiler will attempt to draw it's initial start up current (some 20 to 30 amps with a diesel boiler) down the small ground connection between the timer and the boiler.

The run time is increased according to Peukert's Exponent according to the equation Tc = Cc n where Tc is the change in run time expressed as a ratio, Cc is the change in battery capacity expressed as a ratio and n = Peukert's exponent. So with Peukert's exponent at 1.3, a change in battery capacity from 400Ahrsto

In actual fact what we find is that more current is drawn from the bottom battery, with the current draw getting progressively less as we get towards the topof the diagram.

SMARTGAUGE ELECTRONICS Peukert in brief. A quick explanation of the two main versions of the formula. For those who understand the effect but need a quick reminder of how to apply the formula. SMARTGAUGE ELECTRONICS Let's take a look at the galvanaic isolator again when installed in a typical installation from some years ago and see what happens. This diagram shows shorepower operating some form of load. SMARTGAUGE ELECTRONICS What will and does cause a problem is the earth connection running from the shorepower socket to the hull of the boat. This gives a direct path for the electric currents thus generated to flow and this is the cause of the problem. SMARTGAUGE ELECTRONICS Page Prev 1 2 3 4 Next.

Two possibilities arise in a marine environment for this problem to ocurr. First is what is known as "stray current" erosion. This is caused by currents (usually DC earth return currents) being forced to use the hull (orany
SMARTGAUGE ELECTRONICS Page Prev 1 2 3 4 Next. Summary of charging, split charging and battery monitoring. The "one way valve" route simply is never going to be ideal. As shown above. But SMARTGAUGE ELECTRONICS T = the time. C = capacity of the battery. n = Peukert's exponent for that particular battery type. R = the battery hour rating, i.e. 100 hour rating, 20 hour rating, 10 hour rating etc. What we have done here is modify the equation to operate effectively given the battery capacity and hour rating. This formula works. SMARTGAUGE ELECTRONICS An in depth analysis of the maths behind Peukert's Equation (Peukert's Law) You will remember from here that Peukert's Equation is usually quoted as being T=C/I n.You will also remember we stated that whilst this equation is correct, it cannot be SMARTGAUGE ELECTRONICS The 50% rule for deep cycle batteries The 50% rule - A Layman's explanation This is a rule that states quite simply, the most economical use of deep cycle batteries comes about when they are, on average, discharged to 50% capacity then recharged. It seems like one of those rules that someone "just thought up". In actual fact it has a sound scientific basis and really does work. SMARTGAUGE ELECTRONICS A simple explanation of surface charge (and surface discharge). This is a term that crops up all over the place. But I don't think I've ever seen a simple explanation of what it is, how it affects recharge times or how it affects discharge times.* - Home -

SIMPLY THE BEST
Simple to fit, simple to use, yet the most accurate.SMARTBANK
SPLIT CHARGER
"Lossless" relay based auto split charging system. MASTERPLEX PRIMARY ELECTRICAL CONTROL SYSTEM WITHOUT A DOUBT THE MOST ADVANCED SYSTEM IN THE WORLD MasterPlex is so revolutionary that it has its own dedicated websiteat MasterPlex .
In a nutshell it combines, in one small enclosure, for up to 4 battery banks, split charging, remote battery isolation, flat battery protection, programmable high/low voltage alarms, programmable switch inputs, LED outputs, volt free relays, dedicated LEDs for built in functions and becomes the central "server" for a complete multiplex control system allowing entire wiring looms to be replaced with a simple plug in "network" cable. Everything is completely user adjustable from PC (Windows) software. Once configured the PC is no longer required. Windows based diagnostics software built in. Take me to the new MasterPlex website....... SMARTGAUGE AND SMARTBANK ADVANCED CHOSEN FOR UK MOD SMARTGAUGE SYSTEM BEING FITTED TO THE MASTIFF II AND RIDGEBACK Click picture for more The new UK production of Mastiff II and Ridgeback PPVs are currently being fitted with SmartGauge battery monitors and the SmartBank Advanced split charge system. The exisiting vehicles are also being retro-fitted with the same equipment. This follows extensive trials with various split charge systems. The MOD are fitting this equipment quite simply because it is the best. Over 700 systems are being installed. MASTERPLEX CHOSEN BY UK MOD FOR MAJOR CONTRACT SUPACAT "JACKAL" RANGE TAKES MASTERPLEX AS "STANDARD FIT"Click
picture for more info Working in conjunction with Merlin Equipment Ltd, SmartGauge is proud to announce that the Merlin PowerBank variant of the MasterPlex has been installed as the backbone of the electrical power system in the Supacat Jackal range of vehicles. Following many months of trials and development work in conjunction with Merlin Equipment, Supacat and Fujitsu the PowerBank has beein installed in a major refit of a number of existing Jackal basedvehicles.
This, again, confirms our position as THE leaders in the powermanagement field.

SMARTGAUGE ELECTRONICS is the design and manufacturing company behind the SmartBank split charge system, the SmartGauge battery monitor and the SmartGuard and PowerGuard battery and engine start protection systems The Proprietor and chief designer, Chris Gibson, has over 25 years experience in the field, spent 10 years as UK service engineer for Heart Interface, was heavily involved in the development of the hugely successful Heart Interface Freedom range of inverters and also operated as UK service engineer for Statpower Technologies for 5 years. He made numerous training visits to the Heart Interface factory in Seattle WA and was heavily involved with major inverter, battery charger, and battery monitoring equipment manufacturers throughout the world for over 15 years. Usually on a freelance consultancy basis, occasionally acting as UK service technician, representative or technical documentation holder for matters relating to European Certification of equipment (CE marking). For more than 10 years he acted as test house for one of the UK's largest independant importers and suppliers of marine and automotive electrical power systems equipment, testing and evaluating equipment ranging from inverters and battery chargers through to battery monitoring equipment and switchgear. In 2003 he formed Smartgauge Electronics in order to design and develop equipment specifically for the marine and automotive DC power markets. This equipment has made enormous inroads into the commercial and military markets and the SmartGauge and SmartBank are now standard fit equipment on a wide range of front line military vehicles andambulances.
