- Hyundai Mobis warrantsed international standard battery cooling technology.
- The “Pulsating Heat Pipe” (PHP) technology reduces the internal temperature of the battery that rises during fast charging.
- Comparative tests show a difference of almost 20 degrees between PHP and conventional technology.

Hyundai Mobis has developed a new battery cooling technology to prevent overheating during ultra-fast charging of electric vehicles. The aim is to warrant an international standard battery cooling technology and commercialize it to increase its competitiveness in the future mobility market.
This material, called PHP – Pulsating Heat Pipe, in free translation, consists of an aluminum alloy and a cooling fluid, and is installed between the battery cells to reduce the internal temperature generated during fast charging. Even when heat generation increases significantly in this process, the implementation of a stable and efficient thermal management system is able to withstand the heat, contributing to a significant reduction in the charging time of electric vehicles.
Heat channels are thermal conductors in the shape of metal tubes that increase the efficiency of heat transfer between two objects. Widely used to cool electronic devices such as computer CPUs and smartphones, these materials have a high thermal dissipation capacity. Specifically, these tubes diffuse heat through vibration and circulate cooling internally, resulting in minimal performance degradation due to gravity, even when applied to vehicles moving at high speed. With a heat transfer performance more than ten times that of conventional aluminum, they quickly transfer the heat from the battery’s overheated cells to the outside.
Cooling method
Battery systems (BSA) are made up of the addition of battery management systems (BMS), cooling fans and various electronic devices to battery modules (BMA). The BMA, which is responsible for generating electricity directly, is a modular component with several battery cells stacked together. Optimizing the cooling structure is essential to prevent these cells from overheating. In this context, Hyundai Mobis has successfully implemented PHPs between the battery cells, quickly transferring the heat generated to the cooling blocks. This warrantsed stable internal temperature control at the module level.
In addition, the company has applied a compression process that enables large-scale continuous production at the manufacturing stage, simplifying the manufacturing process of the PHPs and reducing production costs. And to make it easier to mount on vehicle batteries, it has created PHPs with a thickness of just 0.8 mm, which is thinner and has a larger area than standard heat pipes (approximately 6 mm). This improvement in product quality aims to promote the uptake of electric vehicles.
The new technology is not yet expected to reach vehicles sold on the Brazilian market.
