Hybrid & EV 12V Battery Faults — Dudley Port
Dudley Port hybrid and EV 12V auxiliary battery support. We never touch high-voltage systems — the 12V side is where the fault almost always is.
It surprises people that an electric or hybrid car with a nearly full traction battery can be completely immobile. The high-voltage system cannot close its contactors without the little 12V battery, so a £120 part strands a car with a full charge.
Late shift, night out, early flight — batteries pick the worst moments to die. If you're stranded anywhere from DY4 to the A461 we're on it round the clock.
Off-peak, we don't queue behind a hundred other members. One call, one van, one job — you're not number 87 in a queue.
Why a charged EV can be immobile
Hybrids and EVs are increasingly common on canal-side terraces around Dudley Port, and 12V auxiliary failures now make up a growing share of our callouts.
Locally that means the streets between Dudley Port and Tipton, with access via A461 and A4037 and a practical radius reaching Tipton (~1 mi) and Dudley Port (~1 mi).
Working safely on the 12V side
- Only the 12V system is touched — the high-voltage traction system is never disturbed.
- Once powered, the vehicle's ready state is confirmed and DC-DC converter output is checked to be maintaining the 12V system.
- Genuine 24/7 — nights, weekends, Christmas Day, New Year — same price as daytime
- On a emergency jumpstart the equipment is matched to the vehicle — cranking current, terminal layout and battery location all change the approach.

Hybrid and EV questions
Q.My EV has 80% charge — why is it dead?
Because the 12V battery powers the computers that close the high-voltage contactors. Without it, the traction battery cannot be connected to anything.
Q.Is it safe to jump a hybrid?
Yes, at the designated 12V jump points, which are what we use. The high-voltage system is not involved and should never be touched roadside.
Q.Does driving the car charge the 12V battery?
A DC-DC converter maintains it while the car is in ready mode. Short use and long standing still let it sink, exactly as with a conventional car.
Q.Do you cover Dudley Port and the DY4 area for this?
Yes. Dudley Port is inside our routine coverage from Oldbury via A461, roughly 1 miles from Tipton. We cover it alongside Tipton and the surrounding streets.
Q.Is there a night surcharge?
No. Same price at 3am as at 3pm. We think surcharging people who are already stranded is bad business.
Q.What if my car is in a locked car park overnight?
Tell us on the call — usually a security guard or manager can let us in. We've done this in NCPs, hospital car parks and industrial estates dozens of times.

The short version
An electric car stopped by a lead-acid battery is a strange idea until it happens to you. In Dudley Port it is now one of the most common calls we take, and one of the quickest to fix. That is the whole job: diagnose it properly, fix it once, and explain what caused it.
