BYD recently presented its 60-foot articulated electric bus in Los Angeles, where soon the first five units of the shorter 40-foot buses will enter service.

It’s expected that in near future, Los Angeles will buy up to 25 BYD buses, while Stanford University already purchased 13.

The new 60-foot bus is still awaiting its first orders.

With capacity for 120 passengers and a 547.5 kWh battery pack, this is probably the largest electric vehicle in the US, with range of up to 170 miles.

Two electric motors have a total power of 360 kW and 3,000 Nm of torque.

Recharging takes 2-3 hours at full power depending on how depleted the battery is.

BYD just got some competition. Proterra just introduced a 180 mile, 321 kWh fast charging lithium titanate battery pack for its BEV buses that can be recharged in little over an hour.

The thing I like about BYD’s charging scheme is that all busses can be recharged only using ‘half facilities’.

So, if a facility decides it wants to charge up more busses than normally, it does not need any additional infrastructure :

Busses which must be quickly charged may use the 2 charger set up, and then busses which, schedule permitting, may charge more slowly, can charge using only one facility, thereby either saving the Depot’s demand charges and/or fully utilizing their charging infrastructure investment. Also makes growth in number of busses in time much less painful since they do not automatically at the same time immediately have to add charging to an increased number of busses so this give ‘growth planning flexibility’.

The GreenCarCongress article is WRONG. There are actually two separate batteries with two different CHEMISTRIES in Proterra’s new extended range buses: a fast charging lithium titanate battery, and an higher density NMC chemistry for extended range.

Proterra says it can customize the type and
amount of energy storage on each bus to match its route needs, and
provide the flexibility to quickly reconfigure batteries on each bus to respond to changing route requirements. The 4 to 10 battery packs are “interchangeable” and have “quick-disconnect technology” that allows them to be easily removed and reconfigured as route needs change. The battery packs also have “plug-and-play interoperability between battery types.”

Proterra says that it’s extended range buses “can plug into two chargers at once
for faster charging.” It’s unclear whether each battery chemistry would have to have its own charger and would have to be charged separately.
