Does Rapid Acceleration at Startup Harm the Battery of New Energy Vehicles?
2 Answers
This practice causes significant damage to the battery of new energy vehicles. Explanation of the Principle: When the accelerator is pressed rapidly, the discharge rate of the battery also increases quickly, further reducing the battery's cycle life. New Energy Vehicle Battery: New energy vehicle batteries commonly use ternary lithium batteries, which have the advantages of high capacity and low pollution. The discharge time of lithium iron batteries can be about six times that of alkaline manganese batteries. Compared to nickel-metal hydride batteries, they offer stable discharge voltage and significantly better storage time. The typical lifespan of a new energy vehicle battery is 8 years, with a driving range of 150,000 to 200,000 kilometers. Maintaining a steady speed can extend the battery's lifespan, while aggressive driving can cause certain damage to the battery.
Aggressively stomping on the accelerator when starting a new energy vehicle can indeed harm the battery, primarily because high-current discharge causes the battery's internal temperature to skyrocket. Excessive heat accelerates the aging of battery chemical materials, leading to reduced capacity and shortened lifespan. After driving an electric vehicle for several years, I've noticed that frequent hard acceleration results in faster range depletion, especially during winter. Although most vehicles are equipped with a Battery Management System (BMS) that automatically limits output to prevent overheating, the system's protection isn't foolproof. Over-reliance on it can gradually degrade the battery, increasing replacement costs. In the long run, maintaining smooth starts is the most worry-free approach—it not only extends the battery's service life but also saves money and hassle. An occasional hard start won't cause significant harm, but making it a daily habit would be counterproductive.
