At Eurobike 2015, Samsung SDI unveiled a 500Wh e-bike Li-ion battery pack that can run for 100 km on a single battery charge. Samsung SDI is exhibiting six types of standardized battery packs that can either be built inside or installed on the outside for immediate use.
The company will also display 12 types of battery packs that are currently being supplied to global manufacturing companies and the cells of various specifications. A Bluetooth function which will enable users to check on their smartphones for residual battery, remaining distance, and other data, while riding their bicycles.
Samsung SDI also unveiled a battery pack product equipped with 21700-type batteries, noted for their upgraded energy capacity compared to previous cylindrical types. The 18650 battery, or rather the small cylindrical battery of 18mm diameter and 65mm length, has been in dominant use until recently. However, the creation of new battery applications has boosted the demand for high capacity batteries. In response, Samsung SDI has come up with a battery that has upgraded a maximum of 35% of energy volume, now known as the 21700 battery, and has successfully applied it onto e-bikes for the first in the world.
The 21700 model can have various applications other than e-bike, such as in electric tools, laptops, and more. It is expected to become the new standard in small cylindrical battery usage.
Japan’s secondary cell market research company B3 has estimated that Samsung SDI will follow up its past record of being No.1 for two consecutive years since 2013 in the e-bike lithium-ion battery market and will also come out as the leader this year with a total market share of 25%.
According to market research companies such as Navigant Research and Bike Europe, the global e-bike market is estimated to have reached the number of around 34 million bikes this year. B3 stated in their data that the replacement rate of lead-acid batteries in China has been on the rise and as a result, the demand for e-bike lithium-ion batteries will mark 163 million cells by the end of 2015, which is a 14% increase from last year.
