Savings and Efficiency Tips for Home EV Charging with Time-of-Use Tariffs
Configuring home charging with time-of-use tariffs vs public charging
Charging an electric vehicle (EV) at home can be a great way to save money and reduce emissions. However, it is important to consider the time-of-use tariffs when setting up your charging system. This means that you should avoid charging during high tariff times, which are usually 4-9pm.
If you are using a public charge station, then you may not have the option of setting up your car to only charge outside of these hours. In this case, you may want to consider investing in a smart charger for your home. Smart chargers allow you to set up time windows for when your car will charge, so that you don't have to manually change the settings each time you go out.
When choosing a smart charger for your home, there are two main types of plugs available: NEMA 14-50 Plug and NEMA 6-50 Plug. The NEMA 14-50 Plug is more common and is often used for electric dryers or electric ranges. It is also easier to resell if needed. The NEMA 6-50 Plug is slightly cheaper and is commonly used for RVs and high voltage shop equipment. It does not require a neutral wire, but both plugs deliver the same power on the same circuit.
In addition to smart chargers, you can also use plug in timers to set time slots for when your car will charge. These units are wifi enabled and allow you to set the charge percentage level as well as the time window.
Overall, configuring your EV charging system with time-of-use tariffs can help you save money and reduce emissions. Investing in a smart charger or plug in timer can make it easier to control when your car charges, so that you don't have to manually change the settings each time you go out. It is important to consider the type of plug you need when setting up your charging system, as this will determine the power output.
How can I configure my car to charge at home outside of high tariff times?
You can change the option of charging the car from 'direct charging' to 'charging between certain hours'. Your car will set itself in waiting mode until you will be in the time-frame. Alternatively, you may setup timer slot using 'My BMW' app.
What type of plug should I get for a ChargePoint Home Flex?
Use a smart charger at home to set the charge time windows, then you don't have to change between home and public/work chargers the setting on the vehicle. For your first charger, it is recommended to get a NEMA 14-50 Plug as it is common plug in California and more likely what your electrician will install unless told otherwise. The only advantages of a 6-50 plug are that it's slightly cheaper, and it's a common plug for RVs and high voltage shop equipment if you intend on sharing the outlet.
What are the benefits of public charging?
Public charging offers a number of advantages over home charging. Firstly, it is often faster than home charging, meaning you can get back on the road quicker. Secondly, public chargers are usually located in convenient locations such as shopping centres and car parks, making them easier to access than home chargers. Finally, they are often cheaper than home chargers, as they are usually part of a network that offers discounted rates.
How do I know which public charger is best for me?
The best public charger for you depends on your needs. If you need to charge quickly, then look for a fast charger with a high power output. If you're looking for convenience, then look for a charger that is close to where you need to be. Additionally, check the cost of using the charger before plugging in - some networks offer discounted rates or even free charging if you sign up for a membership.
