JSW Greentech is developing a new dual-surface liquid cooling system for battery packs used in heavy electric commercial vehicles. The technology is designed to manage battery temperatures more evenly and reduce thermal differences between the top and bottom of individual cells.
The company is using active liquid cooling plates on both sides of the battery cells instead of relying only on a single cooling plate at the bottom. This approach is being developed for electric commercial vehicles operating under demanding Indian conditions.

Most commercial EV battery packs in India use a single cooling plate positioned below the battery modules. According to JSW Greentech, this arrangement can create a temperature difference between the upper and lower portions of the cells.
Heavy commercial vehicles often operate with high payloads, long duty cycles and frequent acceleration or uphill driving. These conditions can increase heat generation inside the battery pack.
JSW's dual-surface architecture places liquid cooling plates both above and below the LFP cells. This allows heat to be managed from both sides and is designed to reduce thermal gradients within the battery.

Technology Designed for Heavy EV Operations
JSW Greentech is developing its electric vehicle platform specifically for Indian road and operating conditions. The company's Ampstar commercial EV range includes both trucks and electric buses.
The dual cooling system is part of the company's broader approach to battery and vehicle engineering. By controlling battery temperatures more evenly, the system is intended to support consistent battery performance during demanding operations.
Battery temperature management is particularly important in heavy electric vehicles because battery performance and durability can be affected by operating temperatures.
JSW Also Working on Chassis Durability
Along with battery thermal management, JSW is working on improving chassis durability for commercial vehicles.
The company is using a Pre-Treatment Electro-Deposition, or PTED, coating process on its vehicle frames. According to JSW, the process creates a uniform protective layer over the frame, including welded areas that can be more exposed to moisture and corrosion.
This technology is intended to improve protection against rust and support longer-term durability in demanding operating conditions.
Dual Cooling to Feature in JSW's EV Platform
JSW Greentech has launched the Ampstar brand for its electric commercial vehicle business. The company's official information confirms that its vehicles use a double-cooling battery system developed for Indian climate and road conditions.
Ampstar's planned electric bus portfolio will cover 7-metre to 18-metre buses for staff, city, intercity and school applications. The company is also starting with a 55-tonne electric tractor-trailer and plans to expand its truck range.
The dual-surface battery cooling technology will therefore form part of JSW's wider strategy to develop electric commercial vehicles with in-house engineering and battery technology.
