What Are The Disadvantages Of Electric School Buses? The two biggest disadvantages are cost and range. Although an electric bus is likely to save money in the long term, the initial purchase price is considerably higher.
Thanks to their ability to cut pollutants and climate-altering greenhouse gas emissions while keeping noise levels to a minimum, electric buses improve living conditions for urban residents.
Unlike diesel buses, electric school buses produce no toxic exhaust, so they're much better for children's health. They can also lower greenhouse gas emissions, reduce school operating expenses, create green manufacturing jobs, and support a more resilient grid powered by greater amounts of renewable energy.
In fact, electric school buses have safety features that make the risk of fire even more improbable, including sophisticated battery temperature controls, weather-durable casing and vehicle design that makes battery damage less likely.
As of 2017, 99% of all battery electric buses in the world have been deployed in Mainland China, with more than 421,000 buses on the road, which is 17% of China's total bus fleet. For comparison, the United States had 300, and Europe had 2,250.
BEBs are powered by battery packs that run an electric motor to turn the wheels, the same as battery-powered electric cars. The batteries are recharged by plug-in chargers using electricity from the transmission grid. Since they do not use gasoline or diesel, BEBs do not produce tailpipe pollution.
How much does it cost to replace an electric bus battery? When will that replacement be necessary? The traction battery on an electric school bus could cost around $50,000 to replace, if replacement costs are not covered under warranty. Battery capacity and bus range will decline over time.
Expanding Bus Ranges and Declining Battery Prices Are Making Electric Buses Mainstream Electric buses today can travel anywhere between 150 miles on the lower end to 275 – 300 miles on a single charge.
