I read today that BYD produces almost 2,000 electric buses a week. 99% of the world's electric buses are in China, and they are rapidly transitioning their fleet of 395,000. So far 16% of the fleet is electric. About 4 years to go at current rates.

IndyGo Launches U.S.' First Electric Bus Rapid Transit With BYD K11
https://insideevs.com/news/372058/indyg ... k11-buses/


Starting with thirteen 18m articulated buses, planned increase to 31 by the EoY, on a single BRT route in Indianapolis. Things were delayed when it was found the buses couldn't meet the 275 mile real-world service range requirement, only averaging 208 miles (and that's with new batteries), so BYD installed wireless chargers at some stops, supposedly at no cost to the city.

If a city bus with less than 208 miles of range is a not enough then how about electric school buses?
The average school bus drives well under 100 miles per day and current city bus projects fail to do much over 200 miles then problem solved at least for the schools.

Which is no doubt why California and some other states/municipalities are replacing diesel school buses with BEVs where they're suitable.

Transdev Canada purchasing 27 new electric Lion school buses

https://www.greencarcongress.com/2020/0 ... nsdev.html

Transdev Canada is investing close to
CAD$4.5 million in its fleet of electric school buses with the Québec company Lion, thus becoming, with a total of 31 vehicles, the largest private operator of electric school buses in North America to date. This major investment is made possible by the Québec government’s proactive support policy.

The entire new fleet will be gradually introduced on the school transport networks operated by Transdev from the start of the school year in September 2020, in the Estrie and Montérégie regions of Québec. Transdev’s ambition is to electrify 100% of its fleet of electric school buses parked in its Quebec depots by 2025.

By the end of 2019, Transdev already operated more than 800 electric buses worldwide and should have a fleet (operated and on order) of 1,200 electric buses (batteries, batteries and hydrogen fuel cells) by the end of this year.

Transdev has chosen to develop in Canada a specific energy transition plan for school transportation in Québec because of its dynamic local ecosystem and the fact that the energy produced locally is mostly hydraulic, and therefore among the cleanest in the world. The introduction of these vehicles promises to reduce pollution by 99% compared to thermal vehicles. . . .

Würzburg buys two Solaris electric buses

https://www.greencarcongress.com/2020/0 ... buses.html

. . . Solaris is also providing the charging infrastructure—two stationary chargers with a maximum power of 150 kW and a mobile charger of 50 kW.

The buses will be propelled by electric axles with two integrated traction motors boasting a power of 125 kW each. The power used by the vehicle will be stored in a set of Solaris High Energy batteries with a total capacity of 300 kWh, and it will be replenished using a classic plug-in system.

Featuring a 2+2+0 door arrangement and a passenger counting system, the electric vehicles will be able to offer room on board for 70 passengers at a time, of whom 38 can travel seated.

The electric buses for Würzburg will contain a monitoring system, internal LED lighting, a passenger information system, air-conditioning, USB chargers and an electric heating system. Special ramps placed next to the doors will ease the entry and exit of wheelchair-bound passengers. . . .

system to manage the heating and the air-conditioning systems of the vehicle, including the function of thermal pre-conditioning launched via the eSConnect system. This thermal pre-conditioning is yet another solution devised by the Solaris Office of Development. Used during the bus charging, it optimizes the consumption of electric power during the ride. Due to this feature it is possible to increase the range of the vehicle on a single charge.

So far Solaris has delivered or secured orders for nearly 1000 electric buses in 80 cities in 18 countries. In Germany alone Solaris has supplied or contracted more than 200 electric buses.

Santiago, Chile adds 150 more BYD electric buses

https://www.greencarcongress.com/2020/0 ... 0-byd.html

. . . The buses will run along Avenida Bernardo O’Higgins, the historic central avenue in the Chilean capital and will be operated by Metbus.

With a total of 455 buses in operation, BYD firmly leads Chile’s electric bus market.

Santiago’s electric bus fleet will reach almost 800 units by the end of this year. Chile wants to completely electrify public transportation by 2040.
Szczytno orders two Solaris Urbino 8.9 electric buses

Hamburger Hochbahn to buy up to 530 electric buses from Daimler, MAN and Solaris

https://www.greencarcongress.com/2020/0 ... -ebus.html

. . . An important criterion for the vehicles is range. In the tender, the manufacturers must ensure a range of 200 kilometers (124 miles) for their vehicles. The prescribed range for the articulated buses is remains 150 kilometers (93 miles) due to their higher weight.

The tender provides for “depot charging” buses. However, offers are also welcome which, in addition to the depot charging, also enable “opportunity charging” (charging at the terminal stops) in order to increase the range.

Hochbahn has already gained experience with both processes in the past. The first series-production vehicles, which have been in use since the end of 2018, only charge at the depot. On the innovation line 109, however, vehicles are also used that are recharged via pantographs during operation using a quick charge.

Bustech selects Proterra as battery technology supplier for new electric transit bus in Australia

https://www.greencarcongress.com/2020/0 ... stech.html

. . . Under the partnership, Bustech will incorporate Proterra’s battery technology into the ZDi’s integrated chassis systems. The Proterra battery system powering the all-electric ZDi transit bus will feature 450 kWh of energy capacity that will enable an estimated 325 km (202 miles) of drive range on a single charge. The vehicle can fully charge in about two hours.

Proterra battery packs incorporate features such as liquid cooling with an active thermal management system that will ensure optimal charging and maximize battery life by maintaining a constant battery temperature in Australia’s demanding climate. . . .
