To cope up with the voltage and current demand EV manufacturers have to combine hundreds if not thousands of cells together to form a Battery Pack for a single car. To give an idea the Tesla model S has about 7,104 cells and the Nissan leaf has about 600 cells.
While using a powerful motor is no big deal, the problem lies with designing a Battery Pack that could source enough current for the motor for long time without degrading its lifespan. To cope up with the voltage and current demand EV manufacturers have to combine hundreds if not thousands of cells together to form a Battery Pack for a single car.
The speed, mileage, torque and all such vital parameters of an electric car solely depends on the specification of the motor and the battery pack used in the car. While using a powerful motor is no big deal, the problem lies with designing a Battery Pack that could source enough current for the motor for long time without degrading its lifespan.
A battery can have voltage but no current when it is not connected to a circuit. Voltage, measured in volts, is a measure of the electric potential difference between two points in a circuit. It represents the "push" that causes electric charges to move in a circuit.
Charge voltage is the maximum voltage that a battery can reach. When we charge a battery its voltage gets increased, the value of voltage at which we should stop charging is called as the max. Charge voltage for a lithium cell with 3.7V nominal voltage the maximum charge voltage will be 4.2V. This value can also be found in the datasheet.
Here's a comparison of their voltages: A typical lead-acid battery has a nominal voltage of 2 volts per cell. Therefore, a 6-cell lead-acid battery (such as those commonly used in automobiles) has a nominal voltage of 12 volts. Lithium-ion batteries typically have a nominal voltage of 3.6 to 3.7 volts per cell.
Electric Scooter Batteries: A Technical Guide
E-scooter battery packs are made of many individual battery cells. 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. Each 18650 cell in a battery pack is fairly unimpressive — generating an electric potential of ~3.6 volts (nominal) and having a capacity about 2.6 amp hours (2.6 A·h) …
