The brick-like battery pack is monitored and regulated by an electronic circuit called a battery management system (BMS), which controls the flow of electricity into and out of the battery. To build a battery pack with hundreds or thousands of watt hours of capacity, many individual 18650 Li-ion cells are assembled together into a brick-like structure. In comparison, Li-ion batteries have about 10X the energy density compared to lead-acid batteries. Lead-acid batteries have the benefit of being inexpensive, but suffer from having very poor energy density, meaning that they weigh a lot compared to the amount of energy they store. They are also found in some electric scooters most notably, inexpensive children’s scooters from companies like Razor. Lead-acid is a very old battery chemistry that is commonly found in cars and some larger electric vehicles, like golf carts. Some electric scooters with INR chemistry include WePed GT 50e and Dualtron models. Consequently, this reduces the chances of thermal runaway and fire. The presence of manganese lowers the internal resistance of the battery, allowing high current output while maintaining low temperatures. This battery gives high capacity and output current. Lithium Manganese (INR, NMC)įortunately, many quality electric scooters are using the INR battery chemistry - one of the safest chemistries. Lithium iron phosphate (LiFePO 4) aka IFR, LFP, Li-phosphateĮach of these battery chemistries represents a trade-off between safety, longevity, capacity, and current output.Lithium cobalt oxide (LiCoO 2) aka ICR, LCO, Li-cobalt.

Lithium nickel cobalt oxide (LiCoO 2) aka NCO.

Lithium nickel cobalt aluminum oxide (LiNiCoAlO 2) aka NCA, Li-aluminum.

Lithium manganese nickel (LiNiMnCoO 2) aka INR, NMC.Lithium manganese oxide (LiMn 2O 4) aka: IMR, LMO, Li-manganese.Li-ion actually refers to many battery chemistries that involve the lithium ion. They also have excellent longevity meaning that they can be discharged and recharged or “cycled” many times and still maintain their storage capacity. Li-Ion batteries have excellent energy density, the amount of energy stored per their physical weight. h) or about 9.4 watt-hours (9.4 Wh).īattery cells are operated from 3.0 volts (0% charge) up to 4.2 volts (100% charge).More specifically, they are made of 18650 cells, a size classification for lithium ion (Li-Ion) batteries with 18 mm x 65 mm cylindrical dimensions.Įach 18650 cell in a battery pack is fairly unimpressive - generating an electric potential of ~3.6 volts (nominal) and having a c apacity about 2.6 amp hours (2.6 A Types of Batteries 18650 Li-ion cells, pictured above, make up an e-scooter’s battery pack | Credit: Wikimedia Commons under CC BY-SA 3.0.Į-scooter battery packs are made of many individual battery cells. Additionally, batteries are one of the most expensive components of the scooter and overall cost increases accordingly. However, they also increase the size and weight of the scooter - making it less portable. In a scooter, the battery pack is made of individual cells and electronics called a battery management system which keeps it operating safely.īigger battery packs have more capacity, measured in watt hours, and will let an electric scooter travel further. Many electric scooters for kids and other inexpensive models contain lead-acid batteries. Most electric scooters will have some type of lithium ion-based battery pack due to their excellent energy density and longevity. The battery is your electric scooter’s “fuel tank.” It stores the energy that is consumed by the DC motor, lights, controller, and other accessories. He has helped develop the technologies behind the ESG website and authors articles covering the science and technology around the technical aspects of electric scooters.
