This means if you purchase a ChargePoint Home Flex today, you'll most likely have more than enough power to charge any EV you have now, and also for any EV you buy in the future.Īlso notable is that if you have an EV that charges at a lower rate, you don't need to be concerned about having too much power, because the car always dictates how much power it receives. Charging at 48-amps would prove more than fast enough, even for the larger-sized battery EVs. Secondly, home charging simply doesn't need to be that fast, as the cars are parked there for many hours every day. Tesla use to offer dual 40-amp chargers on the Model S and Model X, but they discontinued that offering for a couple of reasons.įirst, it became clear that the electrical service on most residences, even newer construction, couldn't supply a dedicated 100-amp circuit necessary for the 80-amp charger without a very expensive upgrade. This will likely remain the case for the foreseeable future, as most OEMs are signaling that they won't offer AC charging at a rate higher than 40 to 48-amps. With the ability to deliver a full 50-amps, the ChargePoint Home Flex can charge any EV sold in the US today at its maximum AC charging rate. For a fair apples-to-apples comparison, the ChargePoint Home Flex is better compared to another WiFi-connected smart-charger, like the JuiceBox Pro 40. ClipperCreek also has higher-powered units, like the HCS-50, which can deliver 40-amps of power, but it's not a smart-charger. I use the term "smart-charging" because the JuiceBox and Home Flex units are both WiFi-connected smart-chargers. However, with the new Home Flex, ChargePoint is upping the EV smart-charging arms race with the ability to deliver up to 50-amps of power to an EV. Use this, for instance, if you have a lower power circuit breaker that you want to ensure is not tripped during charging.The ChargePoint Home Flex charging my Tesla Model 3 at the maximum 48-amps that the car can accept. Yes, you can adjust the charging power limit in the JuiceNet app or dashboard settings. It may be worth having an electrician check the wiring all the way back to the breaker box.Ĭan I adjust the output power (amperage) of my JuiceBox. If this issue has occurred consistently since you installed the unit, check your installation. Also check the cable handle for any issues with the top button, as described above. Try twisting the charging cable as it enters the JuiceBox unit. It may be that the charging cable has been twisted out of place by repeated movement. Check your entire charge circuit (from EV to breaker box). If this is a newly occurring issue, it is likely that it is the result of some kind of environmental damage. This could be due to a legitimate reason, such as water in your charge cable or EV charge port, a cut or fray in your wiring (from J1772 charge cable to supply-side wiring), or an obstacle in way of your charge plug. Your JuiceBox is cycling on and off in response to Ground Fault Interrupt (GFI) instances. My JuiceBox begins charging my EV, but the charge is disrupted by my unit clicking on and/or off?: If it does not click, or clicks very early, the J1772 handle has been damaged, and you can fix it by referring to this doc ( Please make sure your JuiceBox is unplugged before attempting this! ): J1772 DOSTAR Plug - Release Lever Fixes The release lever on the charging handle is also a "Stop" switch.It should click approximately half-way through the action of pushing the button. As you're pressing the release latch, make note of at what point in the press you hear a small click from the switch in the handle. Check the button pressing action on your plug handle.Check your EV charge port for physical damage or evidence of electrical damage.Make sure there are no charge schedules requiring override on your JuiceBox, through the app or the Dashboard.If there are, make sure that you are not currently within one of your preset charging schedules.
