Common problems and malfunctions of CHOETECH charging stations
Despite their thoughtful design, CHOETECH stations are subject to wear and tear and the influence of operating factors.
1. The station does not turn on.
The most common situation is that the device is completely “dead”.
Reasons:
-
power board failure;
-
overheating and burnout of transistors;
-
controller software failure;
-
open circuit in battery circuits.
2. Does not charge from the mains or car
The problem concerns the input circuits.
Reasons:
-
Charging controller malfunction;
-
problems with DC or Type-C connectors;
-
damage to the MPPT controller when charging from a solar panel;
-
oxidation of contacts.
3. Incorrect operation of 220 V outputs
The inverter often suffers from overload.
Reasons:
-
MOSFET transistor breakdown;
-
damage to inverter drivers;
-
protection triggered due to faulty BMS;
-
temperature sensor malfunction.
4. The battery drains quickly or doesn't hold its charge
The battery pack is the most worn part of the station.
Reasons:
-
lithium cell degradation;
-
disturbed battery balance;
-
BMS damage;
-
cyclic wear.
5. Overheating of the case
The station gets very hot even under light load.
Reasons:
-
non-working cooling fans;
-
dried thermal paste or destroyed thermal pads;
-
temperature sensor failure.
6. Errors on the screen and strange behavior of the station
Jumping indication, incorrect numbers, false warnings.
Reasons:
-
firmware failure;
-
damage to current/voltage sensors;
-
problems with the main controller board.
7. Mechanical damage
After the fall the following is possible:
-
disconnection of contacts;
-
cracks in boards;
-
broken connectors;
-
damage to the case and display.
All these faults can be repaired with professional equipment and experience.
