Amid persistent high temperatures, the stable operation of new energy vehicles faces challenges, but Oswell’s innovative thermal management technologies are helping vehicles cope with extreme environments with greater ease.
On a July afternoon, the ground temperature approached 60°C. A pure electric vehicle was cruising smoothly along the Shanghai-Hangzhou Expressway. Inside, the cabin remained cool and comfortable, but unbeknownst to the driver, the core temperature of the vehicle’s “power brain” (the motor controller) was being precisely maintained within a safe range by the intelligent system.
“In high-temperature environments, the stability and lifespan of the powertrain face severe challenges,” said an engineer at Oswell Co., Ltd. “ Through structural optimization and intelligent monitoring, we’ve made the system both more ‘heat-resistant’ and more ‘intelligent.’”
While the air conditioning keeps passengers cool, the core electronic components of new energy vehicles are constantly “sweating”:
High temperature sensitivity: The failure rate of key components rises with temperature, as if precision instruments were placed in a sauna;
Limitations of traditional solutions: Conventional cooling systems often struggle during long-distance drives or in traffic jams;
Clear user pain points: Sudden power loss or fault warnings compromise the travel experience and sense of safety;
The technical team at Oswell Co., Ltd. noted: “The key to solving these issues lies in making heat dissipation more efficient and ensuring the system better ‘understands’ temperature changes.”
In a core patent approved last year, Oswell Co., Ltd. introduced an innovative design for its heat dissipation structure:
Centralized cooling of hotspots: Placing heat-generating capacitors in the core area of the water-cooled plate to achieve “surrounding cooling”;
Direct-connect heat transfer channels: Power modules (IGBTs) are directly connected to the coolant via specially designed heat-transfer columns, improving heat transfer efficiency by 40%;
Intelligent fluid flow guidance: Specially designed flow-guiding columns within the radiator increase the coolant’s contact area while enhancing flow velocity;
Actual in-vehicle data shows that this design reduces the probability of power interruption in high-temperature environments by approximately 80% and cuts air conditioning energy consumption by about 15%.
To address temperature monitoring blind spots when multiple components are connected in parallel, Oswell Co., Ltd. equips each critical component with an all-weather “temperature monitoring team,” ensuring the system can immediately detect any “unwell” components.
Intelligent Peak Value Detection: A proprietary circuit uses a single detection port to identify the hottest component;
Upgraded Response Speed: Protection is triggered within milliseconds upon detecting abnormal temperature rises;
Based on heat dissipation and monitoring technologies, Oswell Co., Ltd. has established a system capable of sensing, preventing, and adjusting issues, forming a dynamic protection mechanism that ensures more stable and reliable vehicle operation in high-temperature conditions.
Pre-adjustment Mode: Automatically lowers the maximum power output when predicted temperatures approach critical thresholds;
Enhanced Cooling Mode: Activates auxiliary cooling modules to increase heat dissipation intensity;
Safety Protection Mode: Triggers tiered alerts and, if necessary, smoothly reduces speed to protect hardware;
As extreme weather becomes the norm, Oswell’s thermal management technology has been adopted in multiple mainstream vehicle models, serving new energy electric vehicles that traverse high-temperature cities daily. These technological innovations, hidden within the vehicle’s body, are translating into a tangible sense of peace of mind for users: even as the sweltering heat persists, their journeys remain smooth and stress-free.
