No, an intermediate meter (also known as a mid meter) is not mandatory for charging an electric car at home. An intermediate meter is an extra meter that can be installed to measure the electricity consumption for charging the electric car separately. This can be useful for tracking energy consumption and calculating costs.
However, the use of an intermediate meter depends on personal preferences and circumstances. Some people find it helpful to have an intermediate meter to monitor energy consumption specifically for charging the car and to calculate costs more accurately. It can also be useful if you want to share costs with others, such as when settling electricity costs with housemates or reimbursing visitors who use your charging station.
If you choose to have an intermediate meter installed, it is advisable to contact a professional electrician. They can advise you on the options, installation requirements, and costs. It is also important to check whether there are any regulations or rules from your energy supplier or grid operator regarding the use of an intermediate meter.
However, it is possible to measure the energy consumption for charging your electric car using the main meter in your electricity connection. You can record the total energy consumption before you start charging and after charging, and calculate the difference to estimate the consumption and costs for charging your car.
