24/7 emergency callout · Hybrid 12V auxiliary battery
Hybrid & EV 12V Battery Faults — Bedworth
Hybrid or EV dead in Bedworth with a full traction battery? The 12V auxiliary is the usual culprit. Safe on-site testing and emergency jumpstart.
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.
Stuck at the roadside in Bedworth at 2am with a dead battery? We run a genuine 24/7 mobile jumpstart service — same price, day or night, no unsociable-hours surcharge.
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.
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.
Why a charged EV can be immobile
Hybrids and EVs are increasingly common on ex-mining terraces around Bedworth, and 12V auxiliary failures now make up a growing share of our callouts.
Locally that means Bedworth itself plus the neighbourhoods that feed into it, with access via M6 J3 and A444 and a practical radius reaching Nuneaton (~4 mi) and Exhall (~1 mi).

Hybrid and EV questions
Q.Do you cover Bedworth and the CV12 area for this?
Yes. Bedworth is inside our routine coverage from Oldbury via M6 J3, roughly 5 miles from Coventry. We also cover the surrounding neighbourhoods on the same run.
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.
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.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.
Hybrid or EV won't go to ready
We use manufacturer jump points and fit correctly vented AGM auxiliaries. Usually resolved in one visit. Ask for a emergency jumpstart and quote your postcode — CV12 is a routine run for us.

The short version
The 12V auxiliary is the weak link in hybrids and EVs. Test it, replace it with the right AGM unit, and the car comes back to life without recovery. If you would rather plan it than react to it, a emergency jumpstart can be booked for a time that suits.
