What You Need to Know About Electric School Bus Charging Stations

As governments and municipalities throughout the globe set strong decarbonization objectives in the next decades to build a more sustainable society, school transportation fleets confront an electric future that is swiftly approaching. The advantages of Electric school bus charging stations are obvious: better health for our children due to cleaner air and fewer particle emissions, less noise pollution, cheaper fleet expenses, and higher dependability. In a nutshell, everyone benefits.

Where are all of these buses going to be charged?

Another issue that must be solved in order for electric school transportation to expand quickly is where will all of these new zero-emission buses charge? Adequate charging infrastructure is crucial for the deployment of electric bus fleets, and it's a topic we're striving to tackle right now to help with future adoption.

Electric car charging, along with range, is one of the top worries among prospective adopters. The good news is that charging isn't as difficult as it may seem at first.

The bulk of fleet charging is done overnight, when buses would otherwise be idle, with a few exceptions. As an added benefit, fleet operators will begin the day with the equivalent of a "full tank." Daily refueling stops are also no longer required, making dispatch schedules easier to manage. Buses just plug in after their regular runs are completed.

What are the requirements for operating an electric school bus fleet?

It's vital to note, though, that those new, quiet electric buses will need a charging station on the day they're delivered in order to smoothly start operation.

Equipment for supplying electric vehicles

Installing the requisite charging infrastructure requires some forethought and is a critical step that should be considered in conjunction with the car buying process. Installing enough charging isn't as straightforward as putting a new charger (also known as an EVSE, or electric vehicle supply equipment) into the wall, but it's also not unduly difficult — it simply takes some planning.

There are a number of EVSEs on the market, and choosing one might be difficult for individuals who are new to electrification. Depending on the customer's use case, several charging speeds are offered. PEWIN ENERGY believes it is critical to evaluate client demands not only in terms of which vehicle best suits their specific specifications, but also in terms of charging equipment and facility infrastructure.

Your facility's electrical infrastructure

It's critical to have access to a charging station as part of your electric bus operation. After all, here is where the energy that will power your automobiles comes from. A typical facility will have the following features:

• Transformers are electric devices that shift the voltage of electricity from one level to another.

• Electric grid access: An integrated network for providing power to Electric school bus charging stations and, eventually, to the EV.

• A charging meter is a gadget that keeps track of how much electricity is going via a circuit.

Electric school bus charging stations: These are physical locations where electric vehicles may be parked and charged.

When switching to electric school buses, your current bus depot may also be turned into a charging station.

Control software for charging

Electric car charging software may help you enhance how you manage bus charging. Most organizations do not need their buses to be fully charged at all times. Why? You may save money by keeping your buses charged at appropriate levels, depending on the routes and how frequently they are utilized. Keeping your buses fully charged may result in additional power bills.

By aligning driving plans and routes, charging intervals, and vehicle maintenance with demand, power costs, traffic conditions, and charging station availability, EV charging software helps fleet managers maximize energy and bus utilization.

How Do You Pick the Best Electric Bus Charging System for Your School?

There is a lot of new information to manage when it comes to electrifying your school bus fleet. When it comes to Electric school bus charging stations or EVSEs, there are also significant variances (electric vehicle supply equipment). Here's a breakdown of some of those distinctions and why they matter to school bus drivers.

DC vs. AC

AC is the abbreviation for "alternating current." AC is the sort of electricity that enters and exits the electric grid that we all use. The sort of electricity we obtain from batteries like normal AA batteries you use for personal electrical gadgets is known as "direct current." Because electric bus batteries can only store DC power, a converter is required to permit variable charging levels. An inverter is necessary for power conversion in both AC and DC charging, although the location of the inverter differs: either within the bus (AC) or inside the charger (DC) (DC).

Tips for Charging Your AC

#1: Make certain you have the appropriate degree of power.

If your electric bus requires 19.2kW, for example, you'll need an 80 amp charging station.

#2: Select a smart charging method.

Choose a charging solution for your AC that goes beyond "dumb charging" and enables you to charge when rates are low to save money on your power costs.

#3: If you're considering V2G, think about a DC alternative.

V2G with AC charging is feasible but unusual; make sure your electric buses have a bidirectional onboard charger that supports V2G.

DC Charging Advice

#1: DC charging isn't always "quick.

Depending on the charging station supplier, the word "DCFC" (DC Fast Charger) refers to a variety of various power levels.

You can do some basic arithmetic to ensure that your DC station is indeed "rapid charging": Charge time is calculated by multiplying the capacity of the electric bus battery (kWh) by the size of the charging station (kW).

A DC charger with a capacity of 25kW, for example, would take more than 6 hours to completely charge a bus with a 155 kWh battery; a DC charger with a capacity of 60kW will charge within three hours.

#2: Examine the DC charging station's specifications.

You'll need the right voltage output for DC charging, so make sure the electric bus and charging station are compatible.

If your electric bus has an 800V DC battery pack but your charging station only has a 400V maximum voltage output, you won't be able to charge it correctly.

#3: Combine V2G with DC charging to get the most out of V2G.

For V2G operations, DC charging is favored due to utility connection constraints. Check that your DC charger has a CCS1 connection and that your bus supports V2G.
