Power to the pedal: Achieving longer-lasting 13S, 48-V lithium-ion battery packs for e-bikes and e-scooters

The rise in popularity of e-bikes and e-scooters demands an increasing need for longer-lasting e-bike/e-scooter battery packs. A longer run time allows for further travel and less frequent charging.

To achieve longer-lasting lithium-ion (Li-ion) batteries, you can choose one of two methods: either increase the total battery capacity or improve the energy utilization efficiency. Increasing the total battery capacity means adding more or better battery cells, which can significantly increase the overall cost of the pack. Meanwhile, improving energy utilization efficiency gives designers more usable energy without increasing capacity. There are two ways to improve energy utilization efficiency: increase the state-of-charge accuracy and/or reduce the current consumption.
