The development comes as workshops adopt more specialized equipment for EV cooling system maintenance and repair. In May 2025, MAHLE launched E-CARE Fluid in Europe for automated emptying and filling of EV cooling systems, with integrated vacuum and pressure leak testing. Future Market Insights (FMI) finds that the EV battery thermal management upgrade services market is expected to grow from USD 1.0 billion in 2026 to USD 3.2 billion by 2036, representing a 12.3% CAGR during the forecast period. The market was valued at USD 0.9 billion in 2025.
EV battery cooling service is moving beyond basic coolant handling as electric vehicles enter higher-mileage service cycles and thermal management systems become more closely tied to battery safety and charging performance. In February 2025, the USA Department of Transportation stated that FMVSS No. 305a applies to light and heavy vehicles and includes performance requirements for propulsion batteries, increasing the importance of documented and controlled service procedures after thermal circuit work.

Why are specialized EV battery cooling services gaining commercial importance?

For workshops, EV battery thermal management is becoming a defined repair activity rather than a simple coolant replacement job. Battery packs depend on controlled temperature ranges during charging and driving, making coolant flow, pump operation, leak detection, and thermal circuit performance important parts of vehicle service.

The February 2025 regulatory development around FMVSS No. 305a adds another layer to the service requirement. As battery safety performance becomes more closely linked to vehicle compliance, repair providers need procedures that protect technicians while documenting work performed around high-voltage propulsion systems.

Equipment manufacturers are responding to this need with dedicated service solutions. MAHLE's May 2025 E-CARE Fluid system combines automated coolant emptying and filling with vacuum and pressure leak testing. Such equipment can reduce manual handling while giving workshops a more repeatable process for servicing battery cooling circuits.

Parts availability is also becoming important as the installed EV fleet ages. In May 2025, HELLA stated that its aftermarket thermal management range started with 1,200 spare parts and was planned to expand to 6,000 parts by 2027. A broader component portfolio can give distributors and workshops more options when older EVs require cooling-system repairs.

Which services and vehicle types are shaping demand?

Coolant loop upgrades are projected to lead service type demand, accounting for 38.4% share in 2026. Battery cooling circuits require controlled coolant movement to manage heat generated during charging and vehicle operation. Pump performance, coolant condition, valves, and circuit integrity therefore become important checkpoints during thermal service.

Electric buses are expected to account for 34.6% of vehicle type demand in 2026. Fleet operators have a strong incentive to maintain battery thermal performance because cooling problems can affect charging behavior, vehicle availability, and daily route operations. Planned thermal inspections can help identify weak pumps, coolant issues, or leakage before they result in more disruptive failures.

Battery chiller upgrades represent another service opportunity as vehicles experience higher thermal loads. Heat pump retrofits can also support EVs operating in colder climates, where battery warming affects charging performance and available driving range.

Preventive maintenance is becoming increasingly relevant because fleet operators can schedule thermal checks around regular service intervals. This creates opportunities for workshops to combine diagnostics, coolant handling, leak testing, component replacement, and thermal-system performance verification within one service visit.
