6.2 Robomow Power Pack Charging Policy
6.2.1 Overview
A battery is an integral part of the electrical system for most motorcycles, snowmobiles,
ATV's and watercraft.
Even so, batteries often receive less care than they deserve. And
improper care can lead to
shortened battery life
.
Lead acid batteries are used as a power source for the Robomower that demands a constant
and uninterruptible source of energy. The Robomower needs energy to operate the drive motors,
the mowing system, the Main board, and other battery-drive accessories such as the LCD display
and audio.
Glossary
-
Ampere -
The unit for measuring the flow of electric current.
-
Ampere-hour (Ah)
– The current in (A amperes) multiplied by time in (h hours). Used to
indicate the capacity of a battery.
-
Capacity (C)
– Ampere-hours that can be discharged from a battery.
-
Cell
– the minimum unit, which a battery is composed of, consisting of positive and
negative plates, separators, electrolyte, etc.
-
Charging
– the process of storing electrical energy in a battery in a chemical form.
-
Cycle Service
– The use of a battery with alternate repetition of charging and discharging.
The battery cycles are measured to the point where the battery looses 20% of its initial
capacity.
-
Cycle Service Life
– The total number of cycles expected at a given depth of discharge.
-
Discharge
– The process of drawing stored energy out of a battery in the form of electrical
power.
-
Depth of discharge (D.O.D)
– The ratio of discharge capacity vs. the rated capacity of a
battery.
-
Life Expectancy
– Expected service life of a battery expressed in total cycles.
-
Self-Discharge
– Loss of capacity without external current drain.
-
Shelf Life
– The maximum period of time a battery can be stored, under specified
conditions, without needing supplementary charging.
