Update July 2022
Solution with a modular design offering charging power of 150kW, 300kW, 450kW and 600kW
Charging overnight with a low-cost and low-weight interface on the roof of the bus, increasing performance of operations, efficiency and safety of the charging process
Reducing the human-interfaced charging tasks, thus make it possilbe to significantly increase the share of e-buses to be charged in one depot
Cutting-edge technology for smart charging
Given that by the end of 2022, Madrid will have 250 e-buses running in the city, measures to provide adequate and efficient charging will be needed. Inductive charging points have already been implemented in the city (bus line number 76) and most of the recent e-buses purchased have the capability of wireless charging. Thus, the pilot will focus on the following measures:
1) Use of software to monitor and control the power network for charging stations and e-buses, maximizing bus availability and operational efficiency.
2) Use of a combined solution iwth 3 inverted pantographs + 1 wire for overnight charging with a modular design offering charging power of 150kW, 300kW, 450kW and 600kW, enabling charging times of 3-6 minutes using a low-cost and low-weight interface on the roof of the bus.
These will be the first inverted pantographs installed in the city. Besides increasing the power and thus the speed of each charge, the smart and wireless characteristics of this equipment, will increase the efficiency and safety of the charging process.

Trends and Drivers
According to the Mobility Survey conducted in 2014, 13 million trips are carried out in 14.3 million stages every day in the Community of Madrid. From the latter, 73% were done in motorised vehicles and 27% by non-motorised modes. It is worth noting that between 2004 and 2014 the share of NMT increased 2.5% (GFK, 2014). Despite the fact that the number of bike users have increased significantly in Madrid, reaching an estimate of 60,000 - 80,000 trips per day, in the overall figures it’s use is still negligible with 0.7% - 0.9% of the total trips (gea21, 2016).
When it comes to motorised transport, the public/private distribution, expressed in stages, reverses the trend of the last survey, with a decrease in the participation of public transport, with a weight of 46.2% in 2014 compared to 53.2% in 2004. However, this varies depending on the area being considered. Figure 1 shows the trips conducted within and between the different areas (city (turquoise) – metropolitan area (yellow) – community (pink) – beyond), divided by public (red) and private (blue) transport. It can be observed that the lion share of trips corresponds to the ones occurring within the city (3.8 million). Despite the fact that between 2004 and 2014 the participation of public transport decreased from 62% to 60%, it is the only area where public transport dominates (GFK, 2014).
Moreover, in 10 years the motorisation rate in the Community of Madrid went from 0.97 to 1.41, i.e., an increase of 45%. The rate in the city centre, which is the lowest, went from 0.72 to 1.15 cars per household (GFK, 2014).
In terms of public transport, as it can be observed in Figure 2 the Metro is the public transport with the highest share of all public modes of transport, with 40.5%, followed by EMT buses with 29.3%. In comparison to 2004, the participation of these modes (Metro and EMT) has hardly changed. On the other hand, there has been a slight increase in the participation of the Renfe suburban train (12.6% in 2004 and 14.1% in 2014) and a reduction in the participation of the intercity bus, from 17.3% in 2004 to 15.3% in the ESM14 (GFK, 2014).
