Hybrid & Electric Vehicle Auto Repair & Service

When it comes to getting your Hybrid or Electric vehicle serviced you can skip all the rest because we are the best! At Auto Care Plus we are not only passionate about HEV, PHEV, BEV cars and batteries, we are passionate about providing our customers the best service possible. Our mission is is to provide hybrid & electric vehicle owners the best quality products and services available on the market today all at an exceptional value. We offer a white glove service with delivery and installation of our custom battery packs to your home or work ANYWHERE in New England.

While many parts of hybrid cars are similar to conventionally-powered vehicles, powertrain-related repairs are completely different and require specialized training and tooling. There are many more sensitive electronic elements in the hybrid powertrain than in a conventional one. You may need to perform hybrid repairs such as:

  • Electric Motor Testing/Replacement
  • Drive Inverter assembly testing/ replacement
  • High Voltage Battery Pack reconditioning and or replacement
  • Isolation Fault Testing
  • A/C Services (very different from non hybrid vehicles requiring specialized training and equipment)
  • Regenerative Braking System
  • Charging Systems
  • Balancing and Reconditioning of your Hybrid Vehicle’s High Voltage Battery requires very specialized equipment and highly specialized training. This is performed at our Derry facility under our Electrified Auto Care brand. We can perform this battery service at any of our locations in New England and we take care of getting your battery to and from our Derry facility.

Hybrid & Electric Battery Reconditioning & Replacement

There are many options available for a wide range of hybrid & electric vehicles. Whether you drive a Toyota Prius, Camry or Highlander, a Ford Escape, CMax or Fusion, a Lexus Hybrid, a Chevy Tahoe or Volt Hybrid, a Kia/Hyundai Hybrid/Electric, a Honda Civic, Insight or Accord all the way to full electrics like the Nissan Leaf, Chevy Bolt and even Tesla. We begin by performing a state of health check to give you a full understanding of your battery packs current condition. We provide everything from reconditioning your current pack to full battery rebuilds and replacements using only the best High Quality Cell modules – we have the best options to suit your needs and budget. Ask us about the best option for your car. We have fully re-manufactured Hybrid Batteries in stock and ready to go!

Deep Cycle Battery Reconditioning

Deep charge & discharge cycles with cell balancing. This is a necessary maintenance procedure we do to your battery pack that is starting to show signs of cell aging and poor vehicle performance and gas mileage. Hybrid Batteries need tune-ups, too! This is highly recommended every 60k miles. Ask your local dealer about this and they will give you the deer in the headlights stare. The reason for this is because the vehicle manufacturers wanted to offer this service to extend the life of the battery but the dealers have a provision in their franchise agreements that they charge 40% gross margin on parts and so the dealer chose to replace battery packs with new ones to the tune of thousands of dollars in profit vs extending the life and performance of your vehicle at a much less profit margin.

Specially Trained and Equipped

Our technicians are specially trained and we’ve invested heavily into diagnostic equipment and software in order to service electric and hybrid vehicles properly. The owner is an Electrical Engineer trained in electric motors and drives with a passion for perfection! Don’t fall for all the gimmicks from all those who claim to be rebuilding battery packs, motors or inverters.  Check out their about us pages. Is there a face behind the brand? If you don’t see real people….maybe that begs asking some questions. Battery reconditioning is a painstaking process which requires tens of thousands of dollars in specialized equipment and highly specialized knowledge and procedures. As always, you get what you pay for when you do business with us!

Frequently Asked Questions

Do hybrids and EVs need regular maintenance?

Yes — just different maintenance. EVs and hybrids still need tires, brakes, cabin air filters, coolant for the battery and inverter, suspension work, and alignments. Hybrids also still have a gasoline engine with all its normal service needs. What changes is the schedule, not the necessity.

How long does a hybrid battery last?

Most hybrid batteries last well over 100,000 miles, and many go far longer. Degradation is gradual — you typically notice reduced range and more frequent engine operation long before an outright failure. Heat and deep discharge cycles are the main factors that shorten life.

Can a hybrid battery be repaired instead of replaced?

Often, yes. Many hybrid battery failures come down to a few weak modules rather than the entire pack. We test individual module voltages and can frequently replace the failing modules and rebalance the pack for a fraction of the cost of a full replacement — though a full replacement is sometimes the better long-term value. We will lay out both options honestly.

Are hybrid and EV brakes different?

They use the same physical brakes, but regenerative braking does much of the slowing, so pads often last far longer. The catch is that lightly used brakes seize and corrode — especially with New England road salt. We service the calipers and hardware to keep them from rusting in place.

Does cold New England weather hurt EV range?

Yes. Cold reduces battery chemistry efficiency and, more significantly, cabin heating draws substantial power in an EV. Expect meaningful range reduction in deep cold. Preconditioning the vehicle while it is still plugged in is the single most effective way to preserve range.

Is it safe for a shop to work on a high-voltage system?

Only with the correct training, insulated tools, personal protective equipment, and de-energizing procedures. High-voltage systems are genuinely dangerous. Our technicians have the specialized training and equipment required to work on them safely.

Do EVs need oil changes?

Battery electric vehicles have no engine oil to change. They do, however, need gear reduction fluid, battery and inverter coolant, brake fluid, and cabin filter service. Hybrids and plug-in hybrids still have an engine and still need oil changes.

Signs you need this service:

  • Reduced electric-only range or driving range
  • Hybrid or EV system warning light on the dash
  • Vehicle running on gasoline far more than usual
  • Reduced power or a limp-mode message
  • Hybrid battery cooling fan running loudly or constantly
  • Slower charging or charging that fails to complete
  • Regenerative braking feels weak or inconsistent
  • Battery state-of-charge gauge swinging rapidly
  • Check engine light on a hybrid or plug-in vehicle

Our process:

  • Interview about symptoms, charging habits, and range changes
  • Scan all modules, including hybrid, battery, inverter, and charging systems
  • Read individual battery module voltages and evaluate cell balance
  • Test high-voltage system isolation and insulation resistance
  • Inspect the battery cooling system, fans, and filters
  • Evaluate the inverter, converter, and coolant condition
  • Review findings and provide a written estimate
  • Perform the approved repair using proper high-voltage safety procedures and PPE
  • Service, recondition, or replace battery modules or the full pack as appropriate
  • Verify system operation, clear codes, and road test
