How large a lithium battery is needed to run 200 kilometers?
2 Answers
58Ah and above lithium batteries can run 200 kilometers. The designed lifespan of the battery is 27 months, but generally, family cars are more economical, and many new car batteries can last 3-4 years. Signs that a car battery needs replacement: Check the internal resistance and voltage of the battery. If both the internal resistance and voltage fail to meet the specified values, it means the battery needs replacement. If the voltage drops below 10V during discharge, it indicates the battery may have broken grids and must be replaced. The lower the voltage under load, the greater the internal resistance of the battery, and the worse its discharge characteristics. Types of car batteries: Car batteries are divided into conventional batteries, dry-charged batteries, and maintenance-free batteries. Car batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy.
I've been driving for over a decade and currently own an economy car with a roughly 20kWh battery, easily covering 200 kilometers without issues. The key is maintaining steady driving habits and avoiding speeding on highways. Vehicle weight and aerodynamic drag affect range—SUVs typically require over 25kWh. Gentle acceleration helps conserve energy. Temperature also matters; winter increases energy consumption, while summer AC use is surprisingly more efficient. Opt for efficient models like compact EVs—20kWh suffices. Regular maintenance, like checking for wiring wear, extends battery life. In short, depending on model and habits, 20-25kWh reliably delivers 200km—never overlook routine upkeep.
