Automotive
The automotive industry is one of the most technology- and capital- intensive industries in the world, with an extensive supply chain. From traditional sedans, SUVs and multi-purpose vehicles to the highly a nticipated smart electric vehicle industry, the EV sector has become one of the most talked about sectors in the world. Its rapid growth and market share have impacted traditional automobile manufacturers, forcing them to invest heavily in related technologies to vie for a position in the EV market. From AI to communications and entertainment to battery cell packaging, EV manufacturing is bringing new and groundbreaking technologies to consumers.
In addition to the growing fuel and environmental concerns, the need to completely redesign EV systems is an even more difficult challenge for automakers. In particular, EV battery packs, advanced driver-assistance systems, and charging stations all need to have comprehensive thermal solutions, and there is a global R&D competition among auto manufacturers to become the next Tesla, or leader of the EV sector.
T-Global is prepared to help you to open up more possibilities with electric and smart vehicles, including self-driving systems, safety assistance systems, transparent display components, Vehicle IoT and more. We believe that together we can shape the future of the "third living space" for EVs.
Applications of Electric Vehicle Auto Parts:
Electric Vehicle Charging Station
Electric vehicle charging stations generate significant heat during operation, making effective cooling crucial for safety and stability. Common cooling methods include natural convection, forced convection, and liquid cooling. Natural convection relies on natural air flow and is suitable for low-power stations. Forced convection uses fans for higher-power stations, while liquid cooling is used for ultra-high-power systems. High thermal conductivity materials like aluminum alloys or copper are used for heat sinks. Proper internal structure and accurate temperature monitoring ensure stable operation and prevent overheating.
EV Battery Module
Battery charging and use will generate heat, and temperature is the key influence on battery life, charging and efficiency. This is why most batteries are designed to transfer waste heat from the battery to the battery module's outer casing for heat exchange. Because there are gaps between the internal batteries, either one-part thermal putty or two-part potting compounds are used, while a thermally conductive gasket with low thermal conductivity and soft materials (approx. 2.0 to 3.0 W/mk) is applied to the top or bottom of the battery to carry heat to its outer casing.
Advanced Driver-Assistance System
As advanced driver-assistance systems (ADAS) and unmanned driving trends grow, more systems are integrated into ADAS, increasing heat generation that must be managed for proper functioning. The electronic control unit (ECU) is crucial for heat dissipation, as it collects, processes, and outputs control signals. The current design uses thermally conductive gaskets of around 4.0 to 6.0 W/mK with extruded aluminum heat sinks. Since multiple smaller wafers may require thermal solutions, smaller thermally conductive gaskets of varying thicknesses are used to conduct heat to a large area heat sink for dissipation.
Voltage Converter
When gasoline-powered vehicles or electric vehicles are started and begin generating electricity, they require a voltage converter to convert the electricity into the most suitable voltage, either by AC to DC or DC to DC. The waste heat generated at the moment of voltage conversion is considerable, and temperature is a key factor in conversion efficiency, so the heat must be effectively managed. Most of these products are designed to be airtight and usually use thicker heat-conductive gaskets to transfer heat directly to the metal outer casing. Because of this, the material of the heat-conductive gaskets should be soft and preferably elastic, so as to avoid gaps opening at the contact interface due to vibration of the vehicle during movement. The thermal conductivity of the products currently used by the industry falls in the range of 2.0 to 4.0 W/mk.

Car Multimedia Navigation System
Due to embedded media and navigation systems becoming more mainstream in the automotive industry, thermal management challenges have become more pronounced. This is a result of the higher performance and increased functionality of modern systems producing more heat within a similar internal area size as prior systems. Because of the increasing demand for higher definition images and image processing chips, high thermal conductivity thermal gaskets are needed to transfer waste heat to a heat sink. Additionally, heat pipes can be used to carry waste heat to less concentrated areas to solve the problem of excessive heat concentration.

Dashcam
Because of space constraints and increasing video quality demands for external dashcams, manufacturers seek to reduce the temperature of internal chips to raise the reliability of the product. Due to the presence of a camera lens, it is recommended to use low volatility or non-silicon type thermal pads when transferring heat out of the lens to reduce the risk of contamination from volatiles. Because of the limited space available, it is also recommended to use insulated and lightweight ceramic heat sinks together with thermal tape to dissipate heat and reduce electromagnetic interference and transmission. If the design of the product permits, a hole can be cut in the case of the product for natural convection and a small fan can be added to relieve heat when the image processing chip is overheating.
