Proterra introduces ZX5 Max electric bus with 738 kWh pack
15 April 2022
Proterra is increasing the amount of energy onboard its purpose-built ZX5 electric transit bus, delivering more battery storage to help transit agencies scale zero-emission bus fleets with electric vehicle technology. Starting in 2023, the 40-foot Proterra ZX5 Max electric transit bus can be equipped with up to 738 kilowatt hours (kWh) of onboard energy.
Through this enhancement, Proterra transit buses now feature the most energy storage of any 40-foot electric bus available in the North American market. With 738 kWh of battery energy storage, the ZX5 Max can deliver more than 300 miles of drive range on a single charge, depending on route conditions, configuration and operation.
The 35-foot and 40-foot ZX5+ electric bus models can be equipped with up to 492 kWh of onboard energy for routes with less demanding range requirements.
Designed and manufactured in the United States, Proterra’s electric transit buses are equipped with the company’s Proterra Powered battery technology systems.
Proterra Powered’s battery platform leverages industry-leading energy density manufactured for maximum range, a customizable design to fit within a variety of vehicles, and a ruggedized commercial grade housing to withstand harsh environments.
Proterra’s battery systems have been proven through more than 25 million service miles driven by Proterra Transit vehicles and selected by world-class commercial vehicle manufacturers to power zero-emission electric delivery vehicles and work trucks, semi-trucks, construction and mining equipment, school and coach buses, and low-floor cutaway shuttles.
5 tons for 738 kWh battery or
1.7 tons for 70 kWh battery, a 90kW fuell cell and 35kg of H2 in tanks.
And you do not need a night to recharge the bus.

But almost no where to recharge H2, much more expensive. Costs will go down but it will always be much more expensive due to unavoidable losses.

Lets see.
5 tons for 738 kWh battery or1.7 tons for 70 kWh battery, a 90kW fuel cell and 35kg of H2 in tanks.
And the clear winner is: 5 tons for 738 kWh battery. Not because the battery weight is greater. Simply because the cost of operation (fuel, capital cost, and maintenance) is so much less and the time to charge the batteries is generally not a problem for transit buses as they are not used as much at night. This is why most new electric buses are battery electric. Also battery electric uses far less energy so is a much better green solution especially as most hydrogen is made from methane making hydrogen the clear choice for big oil.
