Electric Cars Electricity Consumption in Lahore Please Explain

To ensure a common understanding of basic terms, its important to clarify concepts like ampour o r ampere, which I often see misused by individuals conversant with uneducated battery vendors o r makeshift electricians.

To put it simply, if a motor operates at 1,000W of power for one hour, it will have consumed 1,000 watt-hours Wh of energy, which can also be expressed as 1 kilowatt-hour kWh. For example, a battery rated at 50kWh in theory can generate 50,000W of power for one hour, o r 10,000W for five hours, o r 5,000W for ten hours, o r 5W for 10,000 hours. Although there are other factors to consider, this provides a basic understanding.

Assuming a charging efficiency of 100%, if your electric vehicle EV has a 100kWh battery, it will require 100 units of electricity to fully charge, as 1 unit kWh is used by utility companies. However, this is not always the case as energy can be lost during transmission as heat through conductors and conversion AC/DC o r DC/AC, and these losses must be accounted for.

For optimal performance, lithium batteries prefer to charge at a temperature around 21°C, not too hot o r too cold. Charging in cold weather may result in increased electricity consumption to warm the battery pack. Similarly, hot weather o r fast charging may trigger the EVs cooling system, which may use more energy to maintain a safe battery temperature through a dedicated compressor and heat exchanger, o r by using the on-board AC compressor.

Its important to note that these estimates may vary depending on the EV, charger, and ambient temperature. For example, charging with a standard AC home charger at 120V overnight can yield an efficiency of around 85%, while charging with a 240V AC charger can reach up to 95% efficiency and DC fast charging can approach 99% efficiency.

Additionally, EVs are typically configured to only charge up to 80% for battery longevity reasons. The charging level and schedule may vary, for instance, charging from 20% to 80% overnight in cold weather, o r rapidly charging from 5% to 100% with a hot battery during a long trip stop
