Hybrid

Signature are certified hybrid and electric vehicle repairers. We hold the latest in IMI-approval and certification enabling our technicians to safely repair and work on high voltage systems found on modern hybrid and electric vehicles.
With 15 years of experience in hybrid vehicles we are able to provide all the services a hybrid vehicle owner needs. We offer everything from basic maintenance, servicing and repair, such as battery repair, replacement or rebuild, to comprehensive defect identification and repairs such as gearbox, engine and inverter repairs. We endeavour to keep your hybrid vehicle on the road at a fraction of the time and cost of a main dealer.
Servicing an electric or hybrid car is more about ensuring your car is drivable as in preserving the lifetime (and range) of your car over the coming years. Our diagnostic tools and specially trained technicians are quick to diagnose issues hidden within the complexities of the modern systems introduced by electric and hybrid car technology. This ensures you’re not paying over the odds for workshop hours AND you know you’re getting the most out of your investment in the environment.
This isn’t the sort of work your traditional garage is trained to work on and it’s important for independent garages (such as us) to provide an alternative to the more expensive main dealer services.
There are three basic types of hybrid.
Parallel hybrid

These has an electric motor which can power the car alongside the engine. This allows a smaller engine to be used because the motor can help out when a lot of power is needed. The motor can also act as a generator when the car is slowed down and recover energy to partially recharge the battery
Series hybrids – A small engine runs a generator to charge the battery and a separate motor uses power from the generator and, when necessary, the battery to power the car. Because the engine cannot directly power the car, this arrangement suffers from greater electrical losses and needs a bigger electric motor.
Series hybrids may also make use of stop-start and regenerative braking but they tend not to return as high of EPA-rated mpg.

Plug-In Hybrid (PHEV)

This is one step further along towards a pure electric vehicle. Most of these include all the technologies of a full hybrid, but have an extra trick – they have larger batteries. These can be plugged into the grid and their increased supply of on-board electricity allows them to run in all-electric mode up to 14 miles depending on the make and model.
