Trends in e-bus Technology – Case example Examples of both slow and fast charging electric buses with their key battery type and performance are shown in the figure below. The type of Li-ion battery used as energy storage systems differ depending on the type of e-Bus. BYD Proterra Electric range: ≥155 miles(≥250km) per charge Electric range: up to 30 - 40 miles (48-64 km) per charge Battery Type: Lithium Iron-Phosphate battery Battery Type: Lithium Titanate (LTO) fast-charge Battery Capacity: 324 kWh Battery Capacity: 74kWh Charging Power & Time-80 kW (40 kWx2, 480 V, Charging: Overhead 500kW (0 to 95% SOC in 6 minutes) 3c, AC) 4-6 h; 200 kW (100 kWx2, 480 V, 3c, AC) 2-3 h DownloadedCopyrightCopyright © 2015by © Dustin IDTechEx.

The company’s principal activity is the design, development, manufacture and distribution of passenger cars and buses sold under the BYD brand. It also has a 50:50 joint venture with Daimler AG. BYD is the only manufacturer developing e-bus, full electric passenger cars and Fe battery together in China Electric Bus BYD has a wide range of renewable energy automotive vehicles. The BYD electric bus or BYD ebus, called K9 in China, is an all-electric bus model. It has a 12-meter body length and is 18-ton by weight. It also seats 32 (including the driver) and has a total passenger capacity of 87. Battery Technology The BYD electric buses are powered with in-house developed 324 kWh Lithium Iron-phosphate (LFP) battery, that can recharged in 6 hours for normal charge and 3 hours for fast charge. The electric buses have a long electric range of 250 miles (155 miles) of operation per charge. DownloadedCopyrightCopyright © 2015by © Dustin IDTechEx.

Linear (Fast Charging) In the report, we provide detailed analysis between the battery capacity and weight of the electric buses. The battery capacity used in electric buses range from X kWh to Y kWh depending on: . Bus size, weight and body shape Battery capacity, kWh capacity, Battery . Bus route . Charging time .

Hengtong Ebus Newin Flyer the utong, being one of the world's top Proterra producers of transit buses, has X% of Solaris market share of domestic market. In Zhongtongreport Aleees 2014, they sold 6,823 new energy buses Dongfeng GreenPower and are planning to sell 13,000 new Siemens energy buses in 2016. Jiangsu Changlong Electric Bus Ankai Majority of the electric bus Nanjing Golden Dragon Bus manufacturers are based in China. This BYD Market Value, $ billion Value, Market Xiamen King Long Motor is because as one of the fastest Yutong urbanizing countries in the world, China Optare VDL Bus & Coach is by far the largest market for metro buses, seeking to meet the needs of an urban population already twice the population of the United States.
