Recently, the winter limit test of LSD 2026 was carried out in multiple places synchronously. More than 200 technical personnel from the field of power system R&D gathered in batches to comprehensively promote the performance calibration and verification of the power system for 5 months under the responsibility of the "extremely cold aggressor", and constantly consolidate the reliability and stability of the product under the extreme environment. The winter test will be officially launched in Mohe, Heilongjiang in November 2025, and then transferred to high cold and plateau areas such as Laiwu, Qinghai Golmud and Heihe, Heilongjiang, covering multiple complex working conditions such as extremely cold and low oxygen. The overall test period will last until March 2026.

The models of HalPower participating in the winter test include the newly marketed popular models such as Krypton 9X, Geely Galaxy M9, Smart # 5, Smart # 6, Geely Galaxy Starship 7, and Link 10 EMP. The key winter test power products include 16 key power assembly systems such as DHT160, 3DHT160, DHT290, 3DHT100, Horn B15, Horn D20, and all core new products under research. The winter test mainly focuses on the intelligent control and low temperature reliability of the power system under low temperature conditions, covering the engine calibration, driving calibration, functional safety calibration, energy management control, thermal management control, OBD calibration and other core contents, accurately solving the core pain points of winter vehicles, and comprehensively overcoming the power technology limit challenge under the extremely cold environment.

Under the extreme low temperature of minus 35 ℃, the technical team of Haltz Power cooperates with each other and cooperates internally and externally to continuously optimize the stability of the power system. Focusing on energy management calibration, testers repeatedly optimize intelligent management strategies based on a large number of measured data to ensure that low and low temperature energy consumption always remains optimal and stable; In the thermal management and OBD test, the team focuses on the heating efficiency of air conditioning and system safety status, monitors the key performance parameters and fault warning data in real time, and builds a perfect extreme cold protection system for the vehicle. At the same time, the power technical team is still on the snow-covered test track, through repeated starting, accelerating, shifting, turning and ramp driving and other working condition tests, to achieve full scene and full working condition coverage. Extremely cold quenching for quality. This winter limit test constantly breaks through the technical boundary of the power system by means of full scene and limit verification, aiming at solving the starting reliability, endurance stability and other core problems that users generally pay attention to in winter driving, and providing solid support for product quality.
