For the past several months London has been testing new all-electric buses – the Irizar i2e from Spain.

These are long-range, 12-meter buses with a massive 376 kWh battery pack – one of the largest in the industry. Batteries are Sodium-Nickel combined with super-capacitors.

Range should easily exceed 200 km (124 miles) in real world driving. Charging takes about 5 hours.

Two i2e are operated in London and probably some in Spain. 6 more are to be delivered to France.

Irizar uses Siemens electric motors (180 kW nominal) and 1,400 Nm of torque.

I much prefer hybrid electric busses over conventional, and I suspect I’ll like electric even more. Much smoother, quieter, and less smelly. They’ll be obsoleted by public, self driving mini-pods for all but the densest urban routes, but they’re amazing in the present.

We are many years from public, autonomous pods displacing buses, more like a decade or two. Unless someone miraculously makes dedicated podways appear, in which case you might as well lay track too. But dedicated right of way isn’t in the budget now, and for many years.

I would love to see the specs of those super-capacitors…

me too. 1,000,000 uf @ 250vac?

1,000,000 uF is nothing these days- some stereos have caps of several Farad each. Presumably a nominal vehicle traction drive would have at _minimum_ many tens of F, a bus in particular probably much more.

Great to see more bus makers jumping into electric! Or at least dipping, it’s a start.

London already has at least several dozen BYD e-buses, if I’m not mistaken.

Sodium nickel batteries are an interesting choice. I believe that is a high temperature chemistry, so not very practical for cars.

It always -seemed- to my limited logic that capacitors would be brilliant at regen-capture and 0-1mph bursts to mitigate that load on the batteries, but whether expense, complexity or simply lack of performance, you don’t hear anything about them anymore.
I wonder what their duty is in this configuration..

Maybe because sodium-nickle can’t take very high charge & discharge (rapid stop/go acceleration/deceleration) rates so it needs the s-caps for that? MW
