When it comes to the battery life comparison for electric vehicles, Hunan CTS's offerings stand out prominently. CTS, established in 2011, has dedicated its resources to researching and manufacturing lithium - ion batteries for electric vehicles, and its products demonstrate remarkable longevity compared to many counterparts in the market. The foundation of CTS's long - lasting electric vehicle batteries lies in the selection of high - quality, high - energy - density lithium cells by its experienced thirty - person R & D team. These premium cells are engineered to endure a greater number of charge - discharge cycles without significant performance degradation. In contrast, lower - quality batteries often use substandard cells, which results in a shorter lifespan and reduced efficiency over time. CTS's stringent quality control processes, which adhere to ISO9001 and IATF16949 management systems throughout production, play a crucial role. Every battery undergoes comprehensive testing, including evaluations of performance under various driving conditions, safety checks, and durability assessments. This meticulous approach helps identify and rectify potential issues early, contributing to the extended life of the batteries. Additionally, CTS integrates advanced Battery Management System (BMS) technology into its electric vehicle batteries. The BMS actively monitors and controls key functions such as charging, discharging, and temperature regulation. By preventing overcharging, over - discharging, and overheating, the BMS safeguards the battery cells and significantly extends the overall lifespan of the battery. Many other battery manufacturers may lack such sophisticated management systems or have less - effective ones, which is a key differentiator in CTS's battery life performance. With certifications like MSDS, UN38.3, CE, and IEC 62619, CTS's electric vehicle batteries meet international safety and performance standards, further validating their superiority in terms of battery life.
