According to Forbes, kilowatts (kW) and kilowatt-hours (kWh) are the standardized units for E.V. electricity, referring to their use of energy (kWh) and power — a rate of delivering energy per unit of time (kW). "The average electric car kWh per 100 miles kWh /100 miles) is 34.6. This works out as 0.346 kWh per mile.
Usable storage capacity is listed in kilowatt-hours (kWh) since it represents using a certain power of electricity (kW) over a certain amount of time (hours). To put this into practice, if your battery has 10 kWh of usable storage capacity, you can …
In terms of system sizing – battery sizes are expressed as kilowatt-hours, or kWh. If the average home uses 16kWh, 30% of this during the day and 70% at night, that works out to about 5kWh of daytime usage, and 11kWh of night-time usage. So, simple math would dictate that the average Aussie would need about 11kWh of solar battery storage …
