For e-Bike
The Definition of e-Bike
An e-bike means a two-wheeled vehicle operated by an electric motor and an additional power. It is usually like a regular bicycle but it uses additional power when it needs increased higher speeds. Due to this aspect, the motor which drives the wheels and the battery which supplies the electric power to the motor are seen as the core main components of the electric bike.
PEDELEC (PEdal ELEctric Cycle)
The bicycle whose motor runs when pedaling
(Assist E-Bike that assists a person's pedaling)
Throttle type
The bicycle that moves without pedaling by running the motor
(It is called Throttle Type. An e-Bike driven by 100% battery power)
| PEDELEC | Throttle type |
|---|---|
 |
 |
| Running the motor by the pressure on the pedal | Running the motor by turning the wheel or pushing a button |
| 300Wh ↓ | 300Wh ↑ |
| Europe/Japan Market | China/America/Korea |
| Increase in Pedal assist/Throttle hybrid models Mounting the braking/downhill recharge function for high-priced models |

Samsung SDI's 36V 10Ah(360W) class Lithium Ion Battery Pack for e-Bike …
Lithium ion batteries are mainly used for mobile IT units like laptops and cell phones because of their high energy density and lightness. As pro-environmental green energy has recently become more of a social issue, Samsung SDI has applied batteries to many various fields such as e-bikes, UPS systems, and electric tools (which uses lead storage batteries or nickel-cadmium batteries).
The battery pack for an e-bike developed by Samsung SDI consists of multi-series parallel combination of cells(using 50 lithium ion 3.6V 2.0Ah circular cells that guarantee the best quality and safety). SDI also implements a BMS(Battery Management System that controls the combination of cells. It can produce up to 360W output, and more than 20km of the maximum speed and 40km of cruising range with a 6-hour charge.
Compared to lead storage batteries used for existing e-Bikes, lithium ion battery packs have twice the energy density, 1/3 of the weight, shorter charge time, and three times the life expectancy than that of lead storage batteries.
As a result, they can play an important role in developing lighter and more compact e-Bike products, and also contains an environmentally friendly merit due to lithium ion’s innovative battery life span when compared to lead storage batteries which require frequent replacement.
For convenience and safety for users, a unit measuring and displaying the remainder and a cell temperature sensing unit as well as basic protection circuit s are built-in the system.
As the benefits of lithium ion cells draw attention in the green energy field that the world cares about more and more, Lithium ion battery packs will become available for various outputs which will be given a great deal of weight. As the representative of pro-environmental energy, Samsung SDI will lead the way in this innovation.
