When it comes to purchasing electric vehicles (EVs) for your business, one of the most important factors to consider is how you will charge your fleet. Portable EV chargers are a great solution for businesses because they allow you to charge your EV wherever you need it. However, with limited options on the market, it can be difficult to know what to look for and what is best for your business when choosing a mobile EV charging solution. In this blog post, we’ll discuss the key features to consider when selecting a portable EV car charger for your business.

Charging Speed

One of the most important factors to consider when choosing a portable EV car charger is the charging speed. The charging speed will determine how quickly your EV’s battery can be recharged.

There are 3 main charging levels available, Level 1, Level 2, & Level 3 (DC Fast Charging). Level 1 is plugged directly into a standard wall outlet and is what typically comes with the purchase of an electric car. With this charger, it takes about 40-50 hours to fully charge a vehicle, so it is not a good solution for business operations.

Level 2 chargers are most commonly used for public charging stations. It is much faster than Level 1, but it still can take up to 10 hours to fully charge a vehicle. Level 2 chargers also often require grid updates as they are not able to be plugged into a standard outlet.

Level 3 (DC fast charging) is the fastest level of EV charger available and the most difficult and costly to get. This charger can charge an electric vehicle up to 80% in under an hour.

Compatibility

You’ll want to make sure that whichever portable EV car charger you choose for your commercial vehicles is compatible with the EVs you have. You’ll need to know if the electric cars can accept Level 3 charging and which type of charging port they have; CHAdeMO or CCS. Some vehicles like Tesla have different charging ports altogether, so you’ll need to know if you need adaptors.

Sustainability

No one wants to charge their electric vehicles with a gas generator. To comply with green initiatives worldwide, companies have been adding more and more electric vehicles to their fleets. Look for an EV charger that doesn’t use gas or diesel to deliver power to electric vehicles.

Safety Features

Safety is one of the most important concerns when using a portable charger to charge electric vehicles. Portable EV chargers that come equipped with safety features such as an emergency stop will ensure that you and your EV’s battery are protected from damage while charging.

User Friendly

EV charging equipment can be tricky and difficult to use. Choosing a charger that has a user-friendly interface can greatly improve the portable charging experience. Having a charger that also has indicator lights is helpful. Knowing when the charger is connected and correctly charging is important when out in the field.

SparkCharge created their portable Level 3 charger, the Roadie, with all of these factors in mind. The Roadie was designed to be small enough to fit in any sized vehicle, light enough to be taken anywhere, and modular to deliver exactly what the electric vehicle needs.

The Roadie has a very simple design to make it easy to use, compatible, and safe. It has a one-button start/stop with lights indicating when it is ready to charge and deliver the charge. To safely stop the charge in case of an emergency, the Roadie features an emergency stop button on the top of the charger for easy access. The Roadie can service nearly all-electric vehicles that can accept Level 3 fast charging (including CCS and CHAdeMO).

SparkCharge is dedicated to sustainability and finding green solutions. The Roadie is gas and diesel-free so you can make the green choice when charging your EVs. The chargers are also grid-free meaning they are not attached to traditional infrastructure when charging.

When choosing a portable EV car charger, it is important to consider all of these factors and features. By taking the time to research and compare options, you’ll be able to find a portable EV car charger that meets your specific needs and makes owning and operating electric vehicles in your business more convenient and enjoyable. Companies like SparkCharge are continuing to find and create innovative mobile EV charging solutions to make electric vehicle ownership easy, convenient, and simple for consumers and businesses.

What is a portable EV charger?

Portable EV chargers are an innovation in the electric motoring space trying to tackle a common concern – range anxiety. Although ranges of electric cars have increased significantly in the last decade, with many entry-level EVs easily covering 250 miles and more on a single charge, the worry still persists among some drivers.

A portable EV charger is similar to a battery power bank, which you can use to charge devices such as smartphones, tablets and headphones on the go. They provide a temporary energy boost and, in some cases, even recharge a battery multiple times with ease. While the principle is the same, a portable charger for electric cars doesn’t fully recharge a battery. Instead, it provides enough energy to get an EV to the nearest public charger.

Things to consider before purchasing a portable EV charger

Portable EV chargers only offer around a 20-mile charge, which should be enough to get you to a nearby public charging station. This means portable chargers aren’t suitable for replacing home or public chargers. You shouldn’t rely on them to do the core of your charging due to the very limited range they provide.

Think of a portable charger like an EV emergency charge pack. On long journeys with limited public charger coverage, they can offer some reassurance. If, for whatever reason, you get stuck and run out of charge, portable EV chargers give you the ability to get back on the road quickly, without having to call roadside assistance.

If you plan your journey ahead of time, you likely won’t ever need a portable EV charger. Before embarking on a long trip, we recommend:

  • Taking note of compatible charging stations on the route

  • Having more than one option for each planned charging stop in case your first charging option is out of order

  • Giving yourself extra time should you have to wait at the charging station

What types of portable EV chargers are there?

Although a number of portable chargers for EV drivers were released in the past, there are currently none available to purchase for private consumers in the UK market. These models tended to offer AC charging with power ratings of up to 9.6kW, which is similar to a standard home charger, and were compact enough to fit into a boot. Still, the range these portable chargers could provide was limited to around 20 to 40 miles at most.

There are a limited number of commercial portable EV chargers that are available to purchase. They are of the fast charging (DC) type with power ratings of up to 20kW. They’re larger than portable chargers for private EV drivers and consist of multiple batteries, forming a charging pack with more capacity. Depending on the pack, commercial-grade portable EV chargers can add up to 70 miles of range to an EV battery. They don’t fit into a passenger-sized electric car, like a hatchback or SUV, and will have to be transported in a separate van for roadside assistance.

Can I use any cable with my portable EV charger?

For an AC portable EV charger, you’ll need a cable that is compatible with the charger and your EV. Most slow chargers use a Type 2 vehicle-side connector in the UK with a current rating of 16A. These EV cables are typically thinner, making them easier to handle and store.

Commercial DC portable chargers have tethered cables, so one that is permanently connected to the charger, meaning you won’t need a separate cable. Most vehicle-side connectors for DC charging are CCS connectors. The tethered cable will have a current rating of 32A and be thicker than an AC charging cable. This makes it more difficult to handle and store these cables.

We recommend cables with a length of 5m, as they offer a good reach while being fairly compact when storing. Longer charging cables are available, giving you the option to access charging even if the vehicle isn’t parked up right next to the device. However, with a portable charger, this won’t be an issue and a 5m or even shorter cable should be enough.

Do I need a portable EV charger?

The short answer is no. With some simple planning, you’re unlikely to need a portable EV charger. The limited range they offer will only provide enough energy to take you to the next charging station, so a portable charger isn’t a reliable substitute for a public or home charger.

Considering the upfront cost and limited charging capabilities, using a home charger is still the best way to do the bulk of your charging. The Solo home charger allow you to charge your battery in a cost-effective way.
