What type of battery is better for four-wheeled electric vehicles?
2 Answers
Four-wheeled electric vehicles are better suited with lead-acid batteries. Speed of four-wheeled electric vehicles: Pure electric vehicles with a maximum speed below 50 km/h. Main features of the electronic control: Can prevent sudden acceleration during startup. If the controller detects that the input signal from the pedal exceeds 20% when starting the vehicle, it will trigger the controller protection function (HPD), and the controller will prohibit output; startup sequence protection function (SRO); the microprocessor's power-on self-test performs continuous diagnostics during operation. If a fault occurs, the controller immediately stops output, providing comprehensive protection for both the operator and the vehicle.
After driving electric vehicles for so many years, I've seen all kinds of battery types. Lead-acid batteries are the most basic—they're cheap and easy to find, making them especially suitable for elderly scooters or small urban cars. Their initial cost is low, and replacing one only costs a few hundred yuan, but the downside is they're really heavy and have short range, often needing replacement every two to three years. Lithium-ion batteries are a better choice, especially lithium iron phosphate (LiFePO4) batteries, which offer strong safety performance and long lifespan, lasting around 5 to 8 years. They charge quickly, reaching over half capacity in about half an hour, making the car run more smoothly and losing less power in winter. Although lithium batteries are more expensive, costing several thousand yuan per unit, they save on maintenance hassles and replacement costs in the long run. When choosing, make sure the battery is compatible with your vehicle—don’t DIY it casually. It’s best to consult a professional shop to avoid safety risks. Remember, don’t leave batteries charging overnight, and always use certified chargers to prevent fires. Lead-acid batteries are simple but inefficient, while lithium batteries are efficient but require a bigger investment—just weigh your needs accordingly.
