Figure 6 Charging Algorithm
Battery Temperature Sensor
The BTS, P/No. PM30 (Battery Temperature Sensor) supplied with PM300-BT, measures the temperature of the battery and automatically adjusts, in real
time, to charge the battery properly at compensation rate of – 4mv±10%/°C/cell. In case BTS is not present, the PM300-BT will use 25°C as default.
Voltage Compensation Charging
With a voltage sensor the PM300-BT can automatically adjust its output to compensate the voltage drop caused by a cable.
This assures the right voltage is being delivered for optimal charging.
Adjustable Charging Capacity
Users can adjust the charging current by specifying the battery capacity. The charging current is set at threshold rate of 10% the of the
battery capacity (I = 0.1C) by default.
Lithium Battery Charging
The PM300-BT can be congured to charge Lithium battery. With the Lithium battery, the max charging current will automatically be set at
30% of battery capacity (Imax=0.3C).
2.3 Vehicle Battery Charger
Along with a powerful charger for service battery, PM300-BT offers a oat charge of up to 3A to keep the starter battery charged, whether
connected to the AC main or PV. When the starter battery is less than 12.4V, the PM300-BT starts charging after 30 minutes delay and stops
charging when voltage reaches 12.8V.
2.4 Power Supply Mode
If no battery is attached to PM300-BT unit, it will work as a power supply automatically with a 12.8VDC output.
2.5 MPPT Solar Charger Controller
PM300-BT has a built-in MPPT charger for the service battery with:
Max input voltage 50VDC
Max charging current 20A
Max supply current 30A
2.6 Voltage Charging Relay (VCR or commonly known as a VSR)
PM300-BT master power unit has a built-in voltage charging relay (VCR), which offers a convenient source to charge the service battery by
alternator whilst engine is running.
LEAD ACID BATTERY – When the starter battery reaches 13.4VDC with threshold time delay, the VCR will charge the service battery from
the alternator. The VCR will continue the charging until the starter battery voltage drops under 12.8VDC.
LiFePO
4 LITHIUM BATTERY – When the starter battery reaches 14.0VDC with threshold time delay, the VCR will charge the service battery
from the alternator. The VCR will continue charging until the starter battery voltage drops below 13.5VDC with less than 2A charge to the
service battery with threshold time delay.
NOTE: The PM300-BT, when charging from the starter battery, does not provide the 5 stage charge.
It simply takes whatever power and charging is available from the alternator.
NOTE: PM300-BT If your vehicle is tted with a smart charging system (Variable Voltage or Temperature Compensating), the VCR charge
system may not function correctly and a DC-DC Charging system is recommended.
Please consult your local dealer or installer for further information.
