Charge time is a factor of battery size and charging capability. Current buses can charge at the garage at between 50 and 100kW. This is fast enough to ensure that buses can be charged in 4-5 hours. Short range buses use overhead charging on the street at up to 350kW, charging can take as little as 5-10 minutes at turn rounds at the end of routes. This system has been deployed in Montreal for a small test route. As battery costs are falling, on-street charging will likely not be required in the future as a long range bus can work a full shift and then charge overnight or between shifts in the day.
