Level 3 charging, also known as DC fast-charging, is high-voltage (400 to 800 volts) DC charging that produces a much quicker rate of charge and is typically only available at public EV charging stations. AC electricity is what your house is wired for, therefore Level 1 and 2 charging doesn’t require any special fitment to your home. Level 2 charging uses 240-volt AC electricity. Not all home EV chargers are the same! Charging capability is categorized into three tiers, starting with Level 1 using 120-volt AC electricity. What are the different types of EV chargers? Finally, despite Italian design house Italdesign being credited for the design, we don't think it's nearly as sleek as the Tesla Wall Connector. And this unit is large-far bulkier than the others tested, and it doesn't include any kind of cord management beyond a plug holster that mounts to the wall. Also, the cable that plugs into your home outlet is very short, limiting your mounting options. That info comes in handy when trying to manage charge-time windows. Testers didn't like that the app doesn't display a charging curve or indicate when charging had stopped. This home charger's setup is simple just scan the unit's barcode in the app to add it to your account and connect it to Wi-Fi. That means most EV owners probably have it on their phones already. Output capability: 40/32/16 amps (9.6/7.7/3.8 kW)Įlectrify America's home charging station uses the same app as the company's ubiquitous public fast chargers.The cover also must be removed to reset the Wi-Fi connection, which we did at least a half-dozen times when trying to get ours to connect. The unit can, however, be preordered to a specific setting to save that hassle. Rather than change it via the app, you have to take off the front cover and toggle DIP switches. Like the other units, this one can adjust among various output levels, but that's most difficult to accomplish in the Grizzl-E. Grizzl-E claims to have streamlined the process, but still: buyer beware. After quite a bit of back-and-forth, the Gear Team was eventually able to get a firmware update and connect this unit to the ChargeLab app. However, connection to an app was a pain. It can (theoretically) pair with any EV charging app that uses the OCPP (Open Charge Point Protocol) 1.6. It also had the thickest cables, which were consequently the most resistant to hanging up after charging. Videos on its website show a small off-road vehicle running over it (which seems completely unnecessary for a thing that's mounted on a wall, but hey: image is everything). Grizzl-E touts the ruggedness of its beefy aluminum enclosure. The Grizzl-E Smart is one of the cheapest smart EV charging units on the market.
