How to choose the battery for an electric tricycle?

The opening paragraph points out that the electric tricycle battery capacity needs to be selected according to the actual use, which is directly related to user needs. Combined with the reference source data, stressed that lead-acid batteries are still the mainstream, but the capacity of different scenarios vary significantly: light-duty scooter unloaded range of 40-50 kilometres, trucks need to support several hundred pounds of goods, the family car needs to balance the flexibility and range.

For the elderly mobility, grocery shopping and other light demand, we recommend 48V20Ah lead-acid battery pack. Highlight its advantages: cost as low as 400600 RMB, 8 hours of charging to meet daily, lightweight body (within 200kg). Cite the reference source data to illustrate the unloaded range of 4050 kilometres, suitable for short trips within 30 kilometres per day, to avoid waste caused by over-configuration of the user.

Focus on commercial scenarios such as express delivery and freight transport, and analyse the necessity of high-capacity batteries. Take the 60V45Ah lead-acid battery as an example, explaining that its single piece weighs more than ten kilograms, but can support the load of several hundred kilograms to run 30 kilometres, to avoid frequent charging to affect the efficiency. Contrasting the limitations of small-capacity batteries, it emphasises the need to prioritise range and power over cost or weight for goods vehicles.

Analysing family needs such as picking up children and purchasing, it is recommended to choose 48V20Ah or 60V20Ah batteries. Combined with the data, this type of configuration takes into account the range of about 30 kilometres and the flexibility of the body to meet the daily commute and convenient charging. Compared with the truck model, it highlights the dual needs of ‘lightness’ and ‘sufficient range’ for household scenarios.

summarises the key calculation logic in the referenced source:

• Choose higher voltage for the same capacity (e.g. 60V32Ah has better range than 48V32Ah);
•  Select high capacity with the same voltage (e.g. 48V45Ah range is better than 60V32Ah);
• Remind users to adjust their expectations with the actual load (theoretical range needs to be discounted by 20%).
  Finally, it is emphasised that 58Ah battery is the bottom line to achieve 100km long range, but it needs to be matched with good driving habits.

calls on users to make comprehensive choices based on travelling distance, load frequency and budget, and avoid blindly pursuing high configurations. Reaffirms the typical scenarios for the three major scenarios of light mobility, cargo transport and household leisure, and suggests the cost-effective advantages of lead-acid batteries, providing a clear basis for decision-making for different groups.
