7.4. Glossary

ADC

Analogue to Digital Converter, internal controller hardware to convert

measurements into digital signals for processing

AGM

Battery that the electrolyte is held in the separators between the plate, fitted with

a pressure relief value so it only vents under unusual circumstances

AGM-Ch

Charge profile suitable for a particular type of AGM battery

AGM-M

Charge profile suitable for charging AGM batteries being used in Motive Power

Applications

AGM-R

Charge profile suitable for charging AGM batteries being used in Reserve Power

Applications

Aux TX

Auxiliary transformer used to provide power to the MPC controller when no battery

is connected to the charger

Backplane

Printed circuit board with connectors and components to connect the power

modules to the charger housing

bootload

Setting a microprocessor in a condition where you can load or update its firmware

bulk charge

The first stage of a charge cycle where the charger is outputting maximum current

to recharge the battery as quickly as possible. Stage completes when the voltage
reaches a nominal 75-80% state of charge

Battery capacity at the 5 hrs rate to 1.7Vpc for a motive power battery

Charger Interface

PC software application required to communicate with the MPC controller

charger module

The core module that converts AC power into DC power suitable for charging a

battery

configuration

Setting the necessary adjustments of the MPC Controller to suit the battery and

charging application

Data.csv

CSV file containing the information for configuring the charger to suit a battery,

must be in the same directory as the MMPC Interface application

din rail

Clip on mounting method for fixing electrical components to metalwork

diode

Electronic component that only passes current in no direction

DOD

Depth of discharge, measure of the battery discharge condition, 100% is totally

discharged

dv/dt

Rate of change of voltage, slope of the change in voltage against time

efficiency

Ratio of output power to input power of an electrical device, the higher the

efficiency the less energy is lost as heat

equalize

Maintenance function using a low constant current charge to ensure all cells in the

battery have similar voltages

equalize lockout

Timer to prevent an equalize charge starting after a normal charge until the

battery has had time to cool down

finishing charge

The stage(s) that follow the bulk charge to return the battery from 80 to 100%

state of charge which must be done more slowly than the bulk charge stage

Firmware

Computer code that is embedded in a microprocessor

flash

Process where the firmware is written into the microprocessor’s FLASH memory

Flooded

Batteries that have liquid electrolyte that can freely vent, also referred to as wet

cell batteries

FS3

FS3 Frame Size 3 modular charger that can accommodate up to 3 power modules

fuse

Easily replaced device that internally melts during an electrical fault to prevent

damage to other components

FW Abbreviation for Firmware

GEL

Battery that the electrolyte is trapped in a silica gel, fitted with a pressure relief

value so it only vents under unusual circumstances

harmonics

Higher frequency components being multiple of the 50hz AC power that may

damage or degrade the performance of electrical equipment
