Mercedes-Benz’s most recent electric metropolis bus makes employ of tough-mumble batteries

it be ready now —

The recent abilities has 25-p.c greater energy density than lithium-ion.


  • Mercedes-Benz’s most recent articulated bus is the eCitaro G, and it’s available with tough-mumble batteries.

  • Now not like an electric vehicle, which places the battery pack down low, in the eCitaro G you are going to discover them on the roof.

  • The bus makes employ of a pair of 125kW (168hp), 485Nm (358lb-ft) electric hub motors.

Lithium-ion battery abilities has made impressive gains over time. This day’s cells are more inexpensive than they’ve ever been, nonetheless lithium-ion level-headed leaves plenty to be desired by system of energy density in contrast to liquid hydrocarbon fuels. Which system that inserting sufficient of them in a vehicle to offer it an appropriate differ provides heaps of mass and volume. Which is where tough-mumble batteries attain in.

In a faded battery, a pair of electrodes are immersed in an electrolyte resolution, and it be this liquid electrolyte that enables ions to switch from one electrode to the quite so much of. Nonetheless liquid electrolytes can leak, and that’s now not a huge thing, whether the topic matter is extremely corrosive, as in a lead-acid battery, or highly flammable, as in a lithium-ion battery. So researchers all the device via the enviornment bear been experimenting with batteries that employ a sturdy electrolyte in its set, with a explicit secret agent on the employ of them in electric autos.

And now, it appears it be a abilities that’s ready to be deployed, as Mercedes-Benz accurate introduced that its recent eCitaro and eCitaro G metropolis buses may be available with roof-mounted tough-mumble battery packs, developed in conjunction with the Canadian energy firm Hydro Quebec.

Although exiguous print are level-headed rather puny straight away, Mercedes-Benz says that the tough-mumble pack has a 25-p.c greater energy density than even the most developed lithium-ion chemistry. It additionally says that the tough-mumble battery has a plenty greater carrier existence than lithium-ion and is warrantying these batteries for 10 years or an energy throughput of 280MWh. When configured with a whole of 441kWh onboard (unexcited of seven 63kWh packs), an eCitaro G has a differ of up to 137 miles (220km) below favorable stipulations, or 105 miles (170km) in the depth of cool weather with the bus’s heaters working.

On the other hand, these tough-mumble batteries don’t appear to be good. In explicit, they’re now not ready to fleet-payment at charges equivalent to lithium-ion, which is why Mercedes-Benz is additionally offering the bus with an now not mandatory lithium-ion pack that will well well be charged at 150kW and even 300kW in its set. This makes employ of a nickel-manganese-cobalt chemistry and is available in assemblies of 33kWh that will well well be combined to offer a bus up to 396kWh in whole.
