The battery is the powerhouse of any electric vehicle, driving the motor and providing the necessary assistance for your ride.
However, maintaining a battery pack, especially a Lithium-Ion battery, can be challenging over time. Proper charging and safety precautions are essential to ensure the battery’s performance for another 3-4 years.
This guide covers everything you need to know about electric trike batteries, including tips on selecting the right batteries and maintaining them.
Understanding Battery Functionality
Electric trikes utilize robust motors to propel the vehicle forward, which requires a significant amount of electrical energy. This is where the battery plays a crucial role, providing the required power while maintaining the trike's mobility.
These batteries store electrical energy as chemical energy, which is then converted back based on the power demands of the motor.
Using batteries eliminates the need for a power generator, and they can be compactly stored while retaining their energy for extended periods.
Components of an Electric Trike Battery Pack
An electric trike battery pack consists of several key components:
- Battery Cells: The battery is composed of numerous smaller cells, typically 18650 Li-Ion cells, connected in parallel or series to form larger cells or packs. Each 18650 cell stores an electrical charge, consisting of an anode, cathode, and electrolyte.
- Battery Management System (BMS): The BMS monitors the voltage and current from all the connected cells, ensuring efficient output. It helps prevent any single cell’s voltage drop from affecting the overall battery capacity.
- Controller: The controller serves as the central hub, managing the motor, trike controls, display, sensors, and wiring. It interprets signals from sensors and throttles, directing the battery to provide the precise power needed to drive the motor.
- Housing: The housing protects the battery pack from dust, impacts, extreme temperatures, and water damage, while also making it easier to remove and recharge the battery.
Types of Electric Trike Battery Packs
Electric trike batteries differ primarily in the materials used to develop them, impacting their weight, cost, capacity, charge time, and energy output. The main types of batteries are:
- Lead Acid (GEL): The most affordable option, but also heavier with limited range due to lower capacities. They are less safe for biking because they can discharge large amounts of electricity during a short circuit and may leak flammable gases during charging.
- Lithium-Ion (Li-Ion): The most commonly used battery type for electric trikes. These batteries have a higher energy density and provide more energy in a smaller form factor. However, they are slightly more expensive and their performance can vary with temperature changes. Addmotor’s fat tire electric trikes are equipped with UL-Recognized lithium-ion batteries, ensuring safety and eco-friendliness.
- Lithium Iron Phosphate (LiFePo4): A newer compound, LiFePo4 batteries are more resistant to temperature changes and have a higher energy density than Li-Ion batteries, though they are less commonly used in electric trikes.
Key Considerations When Purchasing an Electric Trike Battery Pack
When choosing a battery pack, consider more than just its capacity. Important factors include:
- Cell Manufacturer: The quality of the battery cells is crucial. Reputable manufacturers like Samsung, LG, and Panasonic offer cells with higher quality and longevity.
- Weight, Voltage, and Compatibility: Ensure the battery is compatible with your trike’s mounting system, ports, weight, voltage, and capacity. A larger battery might offer more range but can be too heavy, while incompatible voltages can damage the motor and other components.
- Price: The battery can be one of the most expensive components of a fat tire electric trike. Higher-priced batteries often indicate better quality, but also consider compatibility, brand, and cell manufacturer when evaluating cost.
- Range, Capacity, and Energy: These terms often refer to the same concept—how much power you can get from your battery. Range refers to the number of miles you can travel on a full charge, which can vary based on riding conditions. Capacity, measured in Amp-Hours (Ah), indicates how much current the battery can deliver over time. Energy, measured in watt-hours, is used to calculate the total power output.
Battery Maintenance Tips
With proper care, electric trike batteries can last beyond their typical 1-2 year lifespan, potentially reaching 3-4 years or more. Here are some tips:
- Remove the battery when cleaning the trike: Water can seep into the housing and damage the battery. Always remove the battery before washing or servicing the trike.
- Use slow chargers: Fast chargers generate excess heat, which can damage the battery. Opt for slower chargers to preserve battery life.
- Avoid extreme temperatures: Both heat and cold can degrade the battery’s chemical composition. Store and charge the battery in a temperature-controlled environment.
- Partially discharge the battery for long-term storage: If not using the trike for several days, keep the battery at 40-80% charge to slow down degradation.
Conclusion
The battery pack is a sensitive and expensive component of fat tire electric trikes, so investing in high-quality batteries and maintaining them properly is essential.
When purchasing a battery, prioritize factors like cell manufacturer, compatibility, and range. Additionally, follow best practices for charging and storage to extend the battery’s lifespan beyond 3-4 years.
