FAQ | KCL Vehicle Battery Consumption Standard

Q1. My vehicle battery seems to be draining overnight. Could the KIA Connect Lite(DCS Premium) Module be the cause?

 A1.
In normal conditions, "No".
The DCS Premium Module consumes only about 3.7 to 4.0 mA while in sleep mode for 8-10 hours, which is well below the threshold that would cause battery drain.

However, during its scheduled wake-up routine (every 1 hour), the module briefly draws about 200 mA for less than 3 seconds. This is an intentional design to maintain LTE connection and report vehicle status (dcs/api/60).
This short spike does not cause battery drain under normal battery conditions.

Q2. Why does my multimeter show a steady current of around 200 mA?

A2.
This may be due to the Hold Trigger function on your multimeter.
If the multimeter's trigger [Hold] is active, it may freeze the peak value (e.g., ~200 mA), giving the impression of continuous high current.

🔧 Solution:
Please disable trigger [Hold] and switch to current [Auto] mode for accurate real-time measurements.

(Note: There was a similar case during a field test in Australia where a peak hold led to a misunderstanding of abnormal current.)

❓ Q3. What does the module do during its periodic wake-up?

A3.
Every 1 hour, the DCS module:

1. Wakes up from sleep

2. Sends a “Vehicle OFF” status to the server via dcs/api/60

3. Re-enters sleep within 3 seconds

This results in a brief current spike (~200 mA), but the total energy used is very small.

❓ Q4. Can I see how this behavior looks over time?

A4.
Yes! Please refer to the diagrams below:

✅ Summary

Tip:
If your vehicle experiences repeated battery drain, also check for:

• Battery age or degradation

• Other aftermarket devices

• Infrequent driving (which may not allow battery recharge)
