Differences Between Electric Vehicle Batteries and Automotive Batteries
2 Answers
1. Differences in Implementation Standards: One follows the GB/T5008 standard, while the other adheres to the GB/T22199 standard. 2. Differences in Type: Automotive batteries are starting-type, characterized by delivering very high current in a short period without requiring continuous operation over long durations. In contrast, electric vehicle batteries operate in the opposite manner, functioning with small currents over extended periods of continuous use. 3. Differences in Internal Structure: Automotive batteries have numerous thin plates to accommodate high current discharge, whereas electric vehicle batteries feature fewer but thicker plates, ultimately optimizing battery performance. 4. Other minor differences include variations in appearance and size, wiring methods, dry charge, wet charge, and the hour rate of charge.
There are significant differences between electric vehicle batteries and regular car batteries. Having driven for over a decade, I've noticed traditional gasoline cars use small 12-volt lead-acid batteries, mainly for ignition startup and powering electronic devices. These have limited capacity, cost just a few hundred yuan to replace, and can often be jump-started if they fail. In contrast, an EV's battery is the heart of the vehicle - a high-voltage lithium battery pack with massive capacity that enables hundreds of kilometers of range, though it's bulky and heavy like carrying large luggage. Charging methods differ completely: EVs require hours to charge and sometimes face frustrating charger shortages, while refueling a gas car takes mere minutes. The driving experience also varies, with EVs offering quiet, smooth operation versus the noisy engine sounds of gas cars. Maintenance costs show huge disparities - replacing a failed EV battery costs tens of thousands and requires professional service, whereas car batteries can be self-replaced. Ultimately, their functions are worlds apart, and understanding which better suits your needs comes with experience.
