EV battery advances create thermal management need

Battery capacity has increased by more than 50kWh across all plug-in hybrid/battery electric vehicles (PHEVs/BEVs), and 150+kW batteries now come with fast-charging capabilities.

These advances in battery technologies are creating a parallel need for a battery thermal management system (BTMS) to ensure higher range, longer life, and superior battery performance.

Passive and active thermal management are key technologies among EVs that use high-capacity batteries, management consulting and research firm Frost & Sullivan reports.

While passive thermal management, such as air-cooled systems, will be the key technology for HEVs, liquid cooling and active thermal management will be popular among PHEVs and BEVs, the California-based company says.

“The use of liquid glycol through cooling tubes and plates between modules will not only help original equipment manufacturers (OEMs) maintain battery efficiency but also allow their vehicles to achieve compliance with stringent battery standards,” Frost & Sullivan mobility industry analyst Arvind Noel Xavier Leo says.

“In the future, OEMs will adopt active thermal management systems that centralise all thermal needs for battery, motor, power electronics, and cabin temperature.”

Frost & Sullivan’s recent analysis, Global Analysis of Electric Battery Market and Battery Thermal Management System for Electric and Hybrid Vehicles, Forecast to 2025, provides in-depth analyses of BTMS and highlights the current and future products of manufacturers.

The study covers the markets of Europe (Denmark, France, Germany, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, and the United Kingdom), China, South Korea, Japan, and North America (the United States).
