In areas with insufficient power supply, solving the range problem of electric tricycles can be approached from several aspects:
- Optimizing battery performance
– Increasing battery capacity: Using batteries with larger capacity, although it may increase costs and vehicle weight, can store more electricity and extend the range. For example, replacing traditional lead-acid batteries with high-performance lithium batteries can provide more sustained power under the same conditions, as lithium batteries have a higher energy density.
– Improving battery efficiency: By improving the battery management system, energy loss during the charging and discharging process can be reduced. For instance, an intelligent battery management system can precisely control the charging and discharging process of the battery, ensuring that the battery is always in the best working condition and improving the overall efficiency of the battery.
- Adopting multiple energy replenishment methods
– Solar charging: Install solar panels on the top of electric tricycles to charge the battery while the vehicle is in motion or parked. This method is particularly suitable for sunny areas, and even if the local power supply is insufficient, it can utilize natural resources to replenish the charge. This method has been applied in KSJ’s products, by adding a 600w monocrystalline silicon solar panel on top of the electric tricycle, generating 0.6KWH per hour, and the generated electricity is directly stored in the electric tricycle’s battery. Under ideal conditions, the electric tricycle can rely entirely on the solar panel for the required power, thereby eliminating the need for traditional charging methods.
– Battery swapping mode: Establish battery swapping stations, where users can quickly replace fully charged batteries when the vehicle’s power is low. This method is as convenient as refueling traditional gasoline vehicles and can significantly reduce “charging wait times”.
Improving vehicle energy recovery efficiency
– Regenerative braking system: Install a regenerative braking system that converts the vehicle’s kinetic energy into electrical energy and stores it in the battery when the vehicle slows down or brakes. For example, when an electric tricycle is going downhill or braking, the motor can reverse to act as a generator, recovering some energy and effectively increasing the vehicle’s range.
