Volvo Buses announced a global partnership agreement with ABB for DC fast-charging solutions for electric-hybrid and full-electric buses.

The goal is to create a city-wide standardized charging system for electric and electric hybrid buses that can charge buses quickly through an automatic roof-top connection system at bus stops.

“The partnership is focused squarely on standardization of automatic e-bus fast charging, including the communications protocol between the infrastructure charging solution and e-bus, the electrical interface and specifications for the rooftop automatic connection system (ACS).”

Charging solution will be based on CCS (EN61851-23) protocol to enable maximum re-use of existing e-mobility technologies, but at higher power levels.

“An electric-bus charging standard will be largely based on the recently adopted global DC fast charging standards for passenger cars, guaranteeing safety and helping stimulate investment, long-term commitment and increased adoption of clean mobility.”

Pekka Tiitinen, head of ABB’s Discrete Automation and Motion division commented:

“We are very pleased to partner with a global transportation industry leader that shares our vision of e-mobility in line with ABB’s commitment of power and productivity for a better world. Urbanization is at a historic high and is stretching transport infrastructure of cities around the world. Our collaboration will help support sustainable and cost-efficient transportation solutions to meet rising commuter demand.”

Håkan Agnevall, President Volvo Buses stated:

“We are delighted to enter into partnership with ABB. Together, we have a complete and competitive offer to cities around the world that want to switch to a sustainable public transport system. Electric hybrid buses and full-electric buses are tomorrow’s solution for urban public transport.”

The first joint project with 12 buses is planned for 2015 in Luxembourg.

“The first joint project will be the implementation of Volvo Electric Hybrids and ABB’s automatic e-bus chargers in the Luxembourg public transport system, where as many as 12 Volvo Electric Hybrid buses operated by Sales-Lentz will be running on existing lines by 2015.”

“The project is integrated into Luxembourg’s Mobility Network linking different mobility projects in the western European country to exploit synergies and develop common visions for the mobility of the future.”

But before this begins, Volvo announced that at the IAA exhibition in Hannover, Germany, in September it will present its new Electric Hybrid bus.

Separately, in 2015 under the ElectriCity project in Gothenburg, Sweden’s first all-electric Volvo buses will be launched.

Facts Volvo’s electric hybrid bus

  •  The bus is equipped with an electric motor that is powered by lithium batteries. It also has a small diesel engine.
  •  The bus is charged quickly at charging stations via an overhead power connection.
  •  The bus can be driven about seven kilometres on electricity alone, covering the distance silently and entirely without exhaust emissions.
  •  Enables  indoor bus stops
  •  75% fuel saving
  •  60% energy reduction
  •  75% CO2 reduction
  •  Recharging 6 minutes at end stations

Facts Volvo’s full electric bus    Electrical drive 100 % of  the route, silent and emission-free

  •     Enables  indoor bus stops
  •     80 % energy reduction
  •     No local exhaust emissions
  •     99 % CO2 reduction
  •     Recharging 6 min at end stations

Facts ABB off-board automatic e-bus fast chargers

  •  Standards-based charger using the proven and safe CCS (EN61851-23) protocol
  •  On-route and depot charging solutions
  •  Flexibility in connecting to different electricity-grid situations
  •  Remote management and service solutions together with high quality hardware provides industry leading uptime
  •  ABB connected services offer flexibility to connect to added-value systems, easy upgrading & cost efficiency
  •  Configurations with several power levels up to 300 kW are available depending on the bus and location
  •  Includes an Automatic Connection System to seamlessly connect to the roof of the Volvo bus without the need for driver intervention

The 7 km on batteries for the hybrid is very disappointing. How hard would it be to do 15 km or 25 km on batteries to make the hybrid go electric 95+% of the time?

BYD is still the world leader and ruler of EV buses.

It’s a different type of solution. They use very fast charging batteries or even supercapacitors, and to use them you put chargers along the route.

It’s a tradeoff between battery cost in each bus and building overhead power connections to serve all buses on a route.

As you can see, ABB & Volvo have an EV bus with much longer range as well.

Well, there is little trade-off in having a battery that could go the whole route. This hybrid was built on purpose to have to use the ICE on a normal route while there had been marginal cost to make it go 100% electric almost all the time.

300 kw charge rate

If it was a car @3 mi/kwh that would be 300×3=900 MPH charging rate (=15 miles/min)

If the bus gets 1 mi/kwh (a guess) it would charge at 300 MPH= 5 miles/minute…..not too bad.

Interesting trade off on hybrid versus pure electric. Which is more expensive: more charging equipment or more batteries.????

also the trade off: which is more expensive: adding an ICE and associated equipment or adding batteries.???

My guess is that the Hybrid wins till battery prices come down more.

anyone got the numbers?

I saw a study made last year by a swedish university that were showing that an all electric bus generally (in swedish conditions) is 25% cheaper in the total cost over the expented life time of the bus (I think it was 6 or 8 years, can’t remember) compared to a standard diesel bus.

All all electric options were a lot cheaper than a diesel bus. No matter if you used a big battery, medium sized battery + fast charging, small size battery + many fast chargers.
The winner were a combination of a decent size battery + fast charging.
They did test on intercity and on routes between citys for up to 200 km (so the longest range battery must have been a BYD sized one of 300+ kWh).

The PHEV version was beaten by all pure EV’s too, by a smaller margin but as long as you don’t have to keep your all electric bus out of traffic for some reason (extremely poor planning with too little battery and no fast charging at the right place) then the option was a no-brainer.

+1, I’m all for 100% electric, but you need to plan for bad-case situations; weather, stop-and go traffic, charging station or power failure, etc.
