Malaysia Pioneers Fast Rechargeable Double-Decker EV Buses (With Toshiba SCiB)

Japanese NEDO (New Energy and Industrial Technology Development Organization) is engaged in Malaysian electric bus demonstration project for the city of Putrajaya.

To be fair, electric buses with fast charging capability aren’t news these days, but besides employing standard transit buses, there will be also be full-size double-decker buses.

NEDO states that thanks to the use of right-sized electric batteries, full-size electric double-decker buses will be on par with diesel ones.

In fact, two double-deckers will be equipped with batteries that can be recharged in 10 minutes many times over, which clearly indicates why Toshiba SCiB is involved in the project.

Because double-deckers are higher, roof-charging stations also will need to be higher, adding a new dimension of incompatibility with running other standard electric buses alongside.

Objectives of the Demonstration

  • Operation of full-sized (12-meter-long) EV buses on main routes by using secondary batteries which have a long service life and super rapid charging ability
  • Deployment of a super rapid charging system in the local transportation network
  • Introduction of a system that monitors bus operation as well as installed battery charging status and condition

1. Project Overview

Putrajaya, the center of Malaysia’s administrative government, where Green City 2025 is being promoted as part of its urban strategy, is an ideal city to showcase EV buses in Malaysia and the ASEAN region. From this viewpoint, NEDO and the city of Putrajaya agreed to collaborate on a project to demonstrate EV buses and concluded a memorandum of understanding (MOU) in July 2015. The objective of the project is to demonstrate a super rapid charging system and the long service life of storage batteries from FY2015 to FY2019, with the aim of creating a smart urban transportation system having improved efficiency.

In addition to the ongoing demonstration, the world’s first demonstration of a bus system using full-sized double-decker EV buses was launched. Since double-decker buses have a higher passenger capacity rate per driver and road space, demand is increasing in urban areas of Malaysia and other ASEAN countries. However, development of double-decker EV buses has been considered challenging due to the road weight restriction.

NEDO succeeded in developing a large double-decker EV bus capable of performance that is at the same level as a diesel vehicle. This was possible due to the use of optimal capacity storage batteries and high-power charging technologies which make ten-minute charging possible. With the cooperation of the city of Putrajaya, NEDO is carrying out the world’s first demonstration using two of these buses. The project is being conducted in collaboration with four Japanese companies: Toshiba Corporation, PUES Corporation, HASETEC Corporation, and Oriental Consultants Global Co., Ltd. Malaysian bus operator Putrajaya Bus (PAPSB) is also participating in the project.

Utilizing Japanese technologies and working together with local companies, NEDO aims to contribute to Malaysia by establishing an EV hub among ASEAN countries. NEDO will also showcase the project and plan for wide-area deployment of urban transportation package projects.

NEDO and the city of Putrajaya agreed to expand their collaboration by amending the memorandum of understanding (MOU) for the demonstration project on June 3, 2016.

So why not use wireless charging where regardless of the bus size the same 200 kW+ fast charger can charge all size buses? There’s got to be some reason.

Yeah, like stupidity?

Don’t underestimate the ubiquitousness, or influence, of human disingenuity.

Overhead charging is incredibly stupid now that wireless exists and is efficient. End of story!

Ok… nice try. But seriously, you and probably aren’t the ones who would know why they wouldn’t choose wireless, but there has to be some good reasons.

I wish I could interact here more with some really knowledgable people on some of these type of things. If anyone like this cares to, I welcome your contacting me:

Perhaps they want 500 KW, not lose 10% of the electricity and not pay a fortune for each charging station and the special induction receivers on the bus side as well as the extra inverter from high frequency AC to battery DC again.

Not quite.
High power wireless isn’t ready yet, and won’t be for some time.
If efficiency is of any meaning to you, there you have it.
Because of the level of power involve any % or fraction of it is lost in form of heat, problem and money.
Nevertheless overhead charging isn’t the only direct charging solution possible.
It could be done sideway or underneath for many kind of buses on a specially guide ramp place along the route that they have to ride.
Wireless, will just be so much more expensive in many ways, that in fact, yes, you can say it’s a stupid thing to do.
But, don’t worry, many, will try and probably achieve some kind of self declare success.
At the end, even a less efficient mean of doing a task that as an overall much more efficient sum would be a gain.

Is the wireless charging really efficient.

Chinese are taking the battery route for the reason that they are efficient.

For the intra-city service, they can have just 100 km range and recharge before starting for the return route or during lunch time.
