The types of batteries commonly used in sightseeing cars are mainly lead-acid batteries and lithium batteries.
Lead-acid batteries
Lead-acid batteries have a long history of application in sightseeing cars and have the following characteristics:
Service life: The charge and discharge cycle life of lead-acid batteries is generally around 300-500 times, which is relatively short
Energy density: Lead-acid batteries have low energy density and relatively short cruising range, and need to be charged more frequently
Safety: The chemical properties of lead-acid batteries are relatively stable, and the risk of safety accidents is low, especially when mechanically damaged, the internal chemicals are not easy to leak
Volume and weight: Lead-acid batteries are large in size and heavy in weight, which is not conducive to the lightweight design of sightseeing cars
Lithium batteries
Lithium batteries have gradually become the main choice for sightseeing cars in recent years, with the following advantages:
Energy density: The energy density of lithium batteries is much higher Compared with lead-acid batteries, it can store more electricity and provide longer driving range.
Charge and discharge cycle life: The charge and discharge cycle of lithium batteries can reach more than 500 times, and some high-quality lithium batteries can even reach more than 1,000 times.
Discharge performance: Lithium batteries have better discharge performance and can provide more stable current output, making the sightseeing car more powerful, especially in climbing and accelerating situations.
Safety: Although lithium batteries have high chemical activity, a complex battery management system (BMS) can effectively prevent overcharging, over-discharging, over-current, etc., to ensure safe operation.
Size and weight: Lithium batteries are smaller in size and lighter in weight, which helps to reduce the overall weight of the sightseeing car and improve driving performance.
