As residents in cities long suffer from the air and noise pollution as the side effect from convenient transportation, electric vehicle is regarded as the solution, however, limited range and long charging time of high-power batteries has become the obstacles of prevailing, as well as the high price (40~50% of two-wheeled vehicle pricing), maintenance required battery.
The answer to LEV users’ anxiety is to separate battery and vehicle, by providing related hardware, battery packs, smart charging/exchange equipment and a cloud-base management system, Energy eXchange Network, EXN™.
Experiment shows professional maintenance can effectively prolong battery life. In general the e-scooter battery life span is around 500 cycles, in terms of time, 1~1.5 years. With proper and professional management, battery pack lifespan can prolong to 2+ years, like GoTech has done in the projects locates in Kenting and Tainan.
GoTech, join ventured with Ping-Tung Bus, established Oodo bike e-scooter rental in Kenting since September, 2013. With over 200 units of e-scooter, e-bikes, targeting at Kenting tourist market, GoTech and PT Bus has successfully implement charging stations in several outstanding tourist sites. In 2014, Oodo bike Rental extends operation in Tainan, echoed with local government’s call to eliminate carbon emission, implemented an additional 100 units of e-scooters, e-bikes, battery exchange, and smart charging solution and EXN.
In Kenting and Tainan’s operation, EXN™ and parallel-designed battery pack proved an efficient management enhances battery safety and life-span, not only most of the SOH of battery remain at 90% after years of operation, the range of one charge extended to 100+KM, right enough to cover major sightseeing sites in Kenting and Tainan.
Original battery packs used in Kenting Oodo bike Rental remain 90%+ SOH since September 2013.
Two parallel-designed 48V 16aH rechargeable Lithium ion battery packs with average 25KM/hr speed, supported by EXN cloud management mechanism, the range extended to 100+KM.
Combination of smart battery pack and EXN cloud management platform, collect, analyze and manage battery information as below:
1. Smart battery packs, beyond general charge/discharge, packs communicate with matching charging/exchange equipment. Patented thermal solution extended battery life-span. Each packs owns individual identification to provides precise battery health, charging/discharging record, and SOH, SOC information
2. Smart Charging/Exchange equipment: provides information exchange service. Battery Exchange system also shorten the charging waiting time for flexible fleet management.
3. Payment management, one of EXN™ applications provides payment management over battery leasing.
