How Volvo plans to manage the life cycle of electric bus batteries and return electricity to the grid

Following the launch of the new Volvo BZL electric chassis in Queensland late last month, Volvo Buses Australia has further committed to “sustainable electric vehicle battery management” throughout the full bus life cycle. .

Volvo Bus Corporation launched the new Volvo BZL Electric Chassis at a virtual live event at the end of September, where Volvo Bus Australia hosted and showcased the new Volvo BZL Electric Chassis complete with Volgren Optimus body.

Now it has revealed that, as part of battery lifecycle management, it is considering the possibility of using its electric buses to sell and feed excess power back into the grid.

“As we start to see a growing demand for electric buses in Australia, we will also see an increase in the number of used batteries,” said Mitch Peden, director of Volvo Australia.

Part of Volvo’s commitment to sustainable electric vehicle battery management is its recent partnership with Stena Recycling in Sweden, one of Europe’s leading electronics recyclers.

Batteryloop, a subsidiary of Volvo Buses and Stena Recycling, will seek to give a “second life” to Volvo bus batteries by using them as energy storage units where capacity limitations that develop over time and pose an obstacle to an electric vehicle are nevertheless more than sufficient. for static energy storage operations.

The lithium-ion batteries of BZL electric buses offer a capacity of up to 470 kWh powering one or two 200 kW motors. Unfortunately, Volvo has not yet provided a range number.

However, the Volvo BZL electric bus charging options are impressive. Options include CCS charging with a maximum charging power of 150kW located at the rear of the bus, as well as roof-top charging with a maximum charging power of 300kW through OppCharge integration which enables charging quickly at stops such as bus stops.

The new Volvo BZL Electric was then to be handed over to the Western Australian Public Transport Authority (PTA), the first domestic customer to operate the Volvo BZL. The Western Australian government announced in mid-2020 that it would trial four of Volvo’s all-electric buses in 2022, and it appears the BZL Electric is the result of that deal.
