As the global economy grows, so does energy consumption, leading to increased greenhouse gas emissions and environmental damage. Electric vehicles (EVs), especially those powered by lithium-ion batteries, aim to reduce these emissions. To function optimally, batteries must be maintained within a suitable temperature range. Heat pipe-based thermal management systems have gained attention for their efficient passive heat dissipation. These systems help keep battery packs at ideal operating temperatures, ensuring uniformity and minimizing the risk of thermal runaway. This article explores the applications and advantages of EVLINK high-voltage coolant heaters in electric commercial vehicles.
Cabin and battery heating are essential for safe and comfortable driving. Besides maintaining cabin comfort and vehicle temperature, HVAC systems must meet regulatory requirements, such as UN R155 for cybersecurity. EVLINK is the first domestic manufacturer of high-power, high-voltage heaters to receive R155 certification. Its products excel in defrosting and dehumidification and promote core high-power, high-voltage heater technology globally.
Key performance requirements for EVLINK heaters include:
Before developing new high-voltage heaters, EVLINK analyzed existing technologies like wire-wound resistors and positive temperature coefficient (PTC) heating. The new heater has been optimized in four key areas:
PTC elements exhibit nonlinear characteristics, with resistance decreasing at lower temperatures and sharply increasing as temperatures rise, leading to self-limiting current. EVLINK's new high-voltage heater incorporates these properties for an efficient and safe heating solution.
EVLINK's 5kW-35kW high-voltage electric heaters (HVCH, PTC heaters) are suitable for various vehicles. The company is committed to advancing electric vehicle technology through innovative and high-quality products, providing optimal heating solutions for global customers and supporting green travel and sustainable development goals.
EVLINK high-voltage coolant heaters have achieved excellent performance in the domestic market and are expanding internationally, providing efficient, safe, and environmentally friendly heating solutions for global electric commercial vehicles.
