BYD has secured the largest ever single order for electric buses in Europe in a deal with Keolis Nederland BV, the Dutch subsidiary of global public transport provider, Keolis. The landmark order comprises 259 pure
Current methods for estimating the energy consumption of electric buses fall into three main categories: empirical, dynamics and data-driven methods. The average power consumption of electric buses used in existing studies includes 1.24–2.48 kWh/km [ 3 ], 1.20–2.90 kWh/km [ 4 ], 1.20 kWh/km [ 5 ], 1.50 kWh/km [ 6 ].
1. Introduction. Electric vehicles, especially pure electric vehicles, have been considered as one of the most ideal traffic tools for green transportation system development with perfect emission performance [1], [2].As the only energy storage units, the performance of batteries will directly influence the dynamic and economic

The use of the HESS has not limited only for the shielding the distractive current spikes to the batteries but in addition, the HESS is an efficient storage system in the EVs. The HESS could increase the efficiency of the EVs by storing the energy from brakes during the deceleration of the EVs. When the HESS is incorporated into the design of
This study aims to develop an energy-saving optimization model for a pure electric bus traveling between two continuous stations to reduce energy consumption. one part dissipates as thermal energy, all-electric buses have kinetic energy recovery systems, and the remaining energy is recovered by the wheels into the energy storage
In the field of commercial vehicles, supercapacitors are mainly used as the energy storage systems for hybrid electric buses and supercapacitor electric city buses. In August 2006, the supercapacitor electric city buses started commercial operation in Shanghai, and in 2010, supercapacitor electric city buses provided green transportation
ROTTERDAM, THE NETHERLANDS (1/12/2022) - BYD, the world''s leading manufacturer of new energy vehicles (NEV) and power batteries, has achieved another significant milestone – the delivery of over 70,000 battery-electric buses to customers worldwide. It is just over a decade since BYD accomplished a ''world-first''
Given the reasons mentioned above, we chose six electric city buses from different brands, models, and routes to ensure the diversity and comprehensiveness of the data measurements. Table 1 provides pertinent information on these selected electric buses. Fig. 1 shows the distribution of selected bus routes on the map. The various
Simpler models have also been preferred in other studies concerning the BEV energy demand estimation (Hayes et al., 2011).More adequate models such as in (Janiaud et al., 2010, Sehab et al., 2011, Lajunen, 2012) focus on the sizing of the electrical powertrain for specific mission profiles.
