If your BG Sync Energy (or BG SyncEV) charger is past its 3-year manufacturer warranty, a sudden failure usually leads to an advice note suggesting a brand-new charger installation or an expensive full circuit board replacement costing hundreds of pounds.
We offer a faster, cost-effective, eco-friendly alternative. By sending just the main internal circuit board assembly to our bench, we can repair the specific power supply or component defect, saving you money and getting your EV wall charger operational again.
Specialising in component-level repair and service of out-of-warranty EV charging hardware, WSMFix is ready to help restore your BG Sync Energy / SyncEV charger. I fix these circuit boards via mail-in or local drop-off near Marine Lake in Weston-super-Mare, providing a rapid turnaround to get you back on the road. This service is significantly cheaper than replacing the unit or buying full manufacturer sub-assemblies.
Is your home wallbox experiencing any of the following symptoms?
The most frequent failure mode on the BG Sync Energy range is a complete loss of power where the front Halo LED remains completely dark. This is almost always caused by a thermal or electrical failure within the internal Switched-Mode Power Supply (SMPS) section on the primary board. Because this low-voltage supply runs 24/7 to power the microcontrollers and status LEDs, power spikes or heat degradation cause it to shut down permanently. My repair service rebuilds the internal power supply module, replaces failed regulation components, and verifies all board power rails.
The repair concludes with a complete diagnostic run on a dedicated bench test rig, confirming communication signals, safety checks, and live charging states A, B, and C.
EV Charger board repair - No Fix, No Fee. Book in via my contact system, send me the PCB, and only pay when the board is fully repaired.
In addition to power supply rebuilds, I address other common component-level failures on the BG Sync Energy series:
If the charger powers up but fails to pass power to the car or shows a persistent Red fault light, the internal high-power switching relays or voltage sense circuits may be damaged. I inspect, test, and replace damaged power switching components and repair affected circuit tracks.
Terminal block heat damage or strain from heavy supply cables can lift or scorch circuit board tracks. Damaged screw terminals are professionally replaced, and high-current traces are rebuilt to ensure safe, solid electrical contacts.
If your car detects the connection but fails to initiate the charge sequence, the Control Pilot signal circuit may be degraded. I trace and repair the pilot communication network using simulated vehicle test loads before returning the board.
I have streamlined the mail-in repair process to keep your downtime as short as possible:

I have nearly 40 years of experience in electronics and electrical engineering. When not working on domestic items, I work in the entertainment industry maintaining and repairing specialist lighting and sound equipment for concerts and other shows. I specialise in fixing things at component level, meaning diagnosis and replacement of individual faulty parts on a printed circuit board (PCB). Often working without schematics, I trace faults using a range of diagnostic techniques and use soldering and rework methods to replace all kinds of electronic components.
My main goal is to promote a repair and re-use culture and give people the opportunity to have their electronic and electrical items repaired rather than having to throw good things away. Because of this, I also volunteer as a repairer at a local Repair Cafe in Weston-Super-Mare.
I don't provide a call-out service or work on large domestic items, but you can drop your circuit board or device to me in central Weston-Super-Mare, BS23. I am currently not taking Home Entertainment at the moment due my workload on other repair types. UK Mail-in service available on certain repairs - contact me!.
