6 FAQs about [What kind of energy battery is suitable for public buses]
Do electric buses need traction batteries?
Electric buses designed for overnight charging need sufficient capacity of the traction battery to travel the all-day route, which is charged overnight at the depot. Thus, one property is very important for traction batteries, and that is specific energy.
What are the requirements for the use of electric buses?
The requirements for the use of electric buses vary greatly from project to project, whether we are considering an intercity vehicle, a suburban vehicle or the most frequently used electric bus for purely urban public transport. Unlike partial trolleybuses, the operator must also deal with the charging infrastructure when purchasing vehicles.
How much energy does an electric bus use?
Let’s say that the total consumption of an electric bus is 1.5 kWh / km. Charging 600 kW for 20 seconds will give the batteries 3.33 kWh (actually a little less because charging losses need to be included), which would be enough to cover 2.86 km.
What are some examples of electric buses?
Another example is the town of Hranice, where the carrier 3CSAD operates urban transport with its electric buses. SOR electric buses run between 50 and 150 km per day. Unlike Třinec electric buses, the vehicles here are equipped with LFP batteries (lithium iron phosphate) with a capacity of 172 kWh.
Should electric buses use LTO chemistry?
The more often an electric bus is charged, the more it can use small and powerful batteries, for which LTO chemistry is ideal. This approach seems to be optimal for urban traffic, but it encounters the need to build a powerful and expensive charging infrastructure.
How does initial SoC affect the energy consumption of electric buses?
