August 19, 2026 — The global EV Battery Coolant Control Valves Market is forecast to grow from USD 410.0 million in 2026 to USD 3,020.0 million by 2036 at a 22.1% CAGR, according to Fact.MR. The market crossed USD 335.8 million in 2025, as EV manufacturers expanded thermal-control systems for battery packs and other electrified powertrain components.

The market is growing because electric vehicles need precise coolant routing during charging, driving and cabin heating. OEM thermal teams are qualifying multi-loop systems that connect battery cooling, heat pumps and other thermal circuits. Electric valves allow software-controlled routing and can support battery preconditioning and pack temperature balance. Multi-way designs can also reduce the number of separate coolant-routing devices.

Industry Evidence

The International Energy Agency (IEA), May 2026, reported that global electric car sales exceeded 20.0 million in 2025, representing about one-quarter of total car sales. The IEA also expects electric car sales to reach 23.0 million in 2026. In South Korea, the Ministry of Trade, Industry and Resources (MOTIR) reported 216,000 electric vehicles sold in 2025, up 52.0%. In the United States, the U.S. Energy Information Administration (EIA), July 2026, reported that hybrid, battery-electric and plug-in hybrid models accounted for 24% of new light-duty vehicle sales in Q2 2026, with BEVs alone representing 6%.

Key Numbers

Segment Analysis

Valve Type: Multi-way rotary valves are expected to lead with 43.0% share in 2026. Their ability to combine several coolant paths can reduce separate routing devices. Proportional valves support variable flow, while solenoid valves serve simpler isolation functions.

Actuation: Electric actuation is projected to account for 68.0% share in 2026. Software-controlled coolant routing supports battery temperature control and wider EV thermal strategies. Bosch's portfolio includes coolant proportional valves for complex switching control.

Vehicle Type: BEV platforms are anticipated to capture 61.0% share in 2026. Battery-only drivetrains require dedicated thermal loops and controlled pack temperatures. PHEVs require routing across both battery and engine operating modes.

Sales Channel: OEM fitment is estimated to represent 78.0% share in 2026. Factory-level validation and warranty control make OEM approval important for coolant valves integrated into vehicle platforms.

Country Growth Outlook

South Korea leads the listed markets at 24.2% CAGR, supported by EV sales growth and local thermal-system suppliers. Hungary follows at 24.0%, with EV assembly and battery integration supporting demand. The United States is projected to grow at 22.8%, supported by battery-platform investment and thermal-module localization.

Japan is expected to record 21.6% CAGR, while Germany reaches 21.5% and France 21.4%. Fact.MR notes that different EV assembly structures and supplier validation capabilities create different market-entry conditions across these countries.

Competitive Landscape

The competitive landscape includes Rheinmetall AG, Robert Bosch GmbH, Schaeffler AG including the Vitesco Technologies portfolio, Hanon Systems, MAHLE Group and Valeo.

Rheinmetall and Robert Bosch show direct relevance to coolant-control valve applications. Bosch provides coolant proportional valves for complex switching and pre-integrated thermal modules. MAHLE brings broader BEV thermal-system capabilities, while Valeo offers Smart Coolant Modules. Hanon Systems contributes integrated EV cooling solutions. Schaeffler, including its Vitesco Technologies portfolio, adds further electrified-vehicle thermal-system capabilities.
