Slot Operation View - Skyrc MC3000 Instruction Manual

SLOT OPERATION VIEW (SOV)
How to get there — In TOV, when there is at least one active slot, clicking its SNB will transfer to
SOV.
How to exit — In SOV, pressing the ENTER button will return back to TOV. Or, after some period
of user inactivity, returns to TOV automatically.

Naturally the slot operation view (SOV) is available for active slots only, i.e. slots with an ongoing
program (SNB: solid red) or slots with a finished program (SNB: solid green). For such slots, SOV
can be accessed through TOV. Apart from the most basic info already given in TOV, it also shows
quantities such as power, energy, time, temperature, internal resistance, and target voltage.
Whenever SOV is transferred back to TOV, the program numbers of the slots are being displayed
for a short period in the info message view (IMV).
The controls in SOV are as follows:
Pressing the UP or DOWN buttons will scroll through the info lines.
In SOV, SNB's of inactive slots are not responsive.
For active slots, clicking the SNB will switch to its SOV, whereas depressing the SNB will fully
stop the slot. The latter will make the SNB turn from solid red or solid green to blinking red-
green.
Similarly to DDV, for busy slots, pressing the STOP button (=Finish) will stop the ongoing
routine and finish the entire program at this point, prematurely. The SNB turns from solid red
to solid green. This function provides some manual interactivity and control, if ever needed.
Pressing the ENTER button (=Return) will return back to TOV.
The top line shows the slot number to the left and the battery type to the right. The items are in
order:
Mode
Shows which kind of operation mode is running, or has finished, in the slot. For example, the
NiMH battery type has 5 possible operation modes: Charge, Refresh, Cycle, Break_in, Discharge.
For fast identification each operation mode is accompanied by a corresponding symbol.
Capacity
Shows the absolute value of the accumulated electric charge as it is being transferred between
device and battery: discharging capacity during discharge routines, charging capacity during
charge routines. At the end of cycling programs such as Break_in, Refresh, or Cycle, the results
of their discharging routines are shown too. The original physical unit is Coulomb, or more
typically, milliAmpere*hour (1mAh).

SLOT OPERATION VIEW (SOV)
Volt
Shows both the actual battery voltage and the end voltage, i.e. the voltage where the charging or
discharging routine is heading towards to terminate the routine. In SPV, for discharging routines
the end voltage is called the cut-off voltage (CUT VOLT), for charging routines it is called the
target voltage (TARGET VOLT), and for the storage operation mode it is called the storage
voltage (TARGET VOLT, too). The physical unit is Volt (1V). While both values are displayed with
2 decimals, internally the device measures with +1mV resolution and accuracy.
D.Current (or C.Current)
Shows the actual current flowing through the battery as it is being measured by a precision sub-
Ohm current sense shunt in real time. Negative values represent discharge currents, positive
values charge currents, according to EE101. The physical unit is Ampere (1A). While the value is
displayed with 2 decimals, internally the device measures with +1mA resolution and accuracy.
Power
Shows the momentary time rate at which electric energy is being transferred between device and
battery. Mathematically, electric power of the battery is simply the product of momentary battery
voltage under load and momentary battery current. Following the passive sign convention,
negative values represent a battery being discharged, positive values a battery being charged.
The physical unit is Watt (1W). Roughly speaking, the max charge power is about 13W/slot, the
max sustainable continuous discharge power is about -13W/device.
Energy
Shows the amount of electric energy which has been transferred between device and battery
since the start of the ongoing charging or discharging routine. A positive value means energy
transfer from device to battery (charging), a negative value means energy transfer from battery to
device (discharging). Not all energy transferred from device to battery is stored in the battery;
some part of it gets lost in the immediate environment in form of dissipated heat, mostly due to the
internal resistance of the battery. The physical unit is Joule, or more typically, Watt*hour (1Wh).
Time
Routine time. Shows the elapsed time since the start of the present routine. A program can
consist of several routines. When a new routine within a program starts, this timer is reset to zero.
Total
Total time. Shows the elapsed time since the start of the program. In SPV, for long-term cycling
make sure to set the parameter of the CUT TIME program option to OFF because CUT TIME is
limited to 1 day, whereas the timer of Total can count up to days and days.
BattTemp
Shows the battery temperature, or to be more precise, the slot temperature. Same value as seen
in GSV, it mostly serves as safety feature for battery overheat protection. To change the
temperature unit, go to GSV and change Temp Unit. Note that physically, temperature is a scalar
field quantity, i.e. any point on the battery surface will have a different temperature and depending
on the charging situation and your environment, the extreme temperature points on your battery
may be notably cooler or warmer than the single value given here.
