Which is better, a 3kW or 7kW home charger?
For home chargers, a 7kW charger is a good choice as it’s a big speed boost over a standard outlet (3kW) and will fully charge most EVs overnight. If you often take long trips then it’s worth using faster public chargers (22kW and above) during pit-stops on your journey. It’s often said that frequent Level 3 fast charging can cause an EV’s battery to degrade over time. But data from industry aggregator Recurrent shows that modern EVs’ software protects battery capacity and range over many years.The cheapest way to charge your electric vehicle would be to rely completely on free charging points, but this might not be the most convenient. You’ll often find that only slow or fast chargers are free of charge, and you might not fancy hanging around in public for long enough to get a full charge on a regular basis.Avoid charging your EV to 100% regularly for daily driving. Aim to keep the battery between 20% and 80% to promote battery longevity. Full charges are fine occasionally—especially for long trips or cold weather conditions. Prolonged high charge levels can accelerate battery degradation and reduce overall lifespan.Explore energy-efficient chargers: Investing in energy-efficient Level 2 chargers can be a wise choice in the longer term. These chargers convert more electricity into usable energy for your EV, reducing waste and lowering your overall bill.
What does level 3 charging station mean?
Level 3 chargers are the quickest of the bunch. Alternatively known as DC fast-chargers, Level 3 chargers are especially useful during long trips that necessitate charges between destinations, as this sort of charging can add around 100–250 miles of range in 30–45 minutes. Level-3 is known as direct current (DC) fast charging, or DCFC. These chargers will primarily provide direct current at higher voltages. These chargers can provide 150-400 miles of range per 1 hour of charging, meaning most vehicles can charge from empty to full in about 30-60 minutes.It’s often said that frequent Level 3 fast charging can cause an EV’s battery to degrade over time. But data from industry aggregator Recurrent shows that modern EVs’ software protects battery capacity and range over many years.Don’t overcharge – Charge up to 80% and then unplug your EV. Once your battery hits this number, charging slows down significantly, which removes the key benefit of rapid charging – its speed. Constant charging above 80% can harm the health of the lithium-ion battery.Level 3 charging isn’t bad for the battery when used appropriately. Research shows the impact is minimal—while fast charging may contribute to slightly higher battery degradation compared to Level 2 charging, the difference is typically only about a 2-3% capacity loss after 50,000 miles.Potential Concerns with Level 2 Charging Heat is a known factor that accelerates the aging process of lithium-ion batteries, leading to reduced capacity and efficiency. However, it’s important to note that modern EVs are designed with advanced thermal management systems that mitigate the effects of heat.
Is level 3 charging possible at home?
Level 3 is not practical for residential use and is only found at select public charging stations. Charge time will vary widely depending on outside temperature and other factors. DC Fast Charging is only available for bZ at this time. A Level 3 charging station, also known as a DC Fast Charger, is the fastest way to charge an electric vehicle (EV). Unlike slower chargers, it delivers direct current (DC) power directly to the vehicle’s battery, significantly reducing charging time.Reduced battery degradation Charging your EV up to 80% can help your vehicle’s battery last longer because the battery finds it easier to charge when it is slightly empty rather than nearly full. Therefore, causing less stress within its charging cycle.Daily Use: Charging to 80% with Tesla chargers strikes the perfect balance between range and battery longevity for routine driving needs. Additional Range: On days requiring longer drives, adjust the charge limit to 90%, ensuring you have sufficient range while still protecting battery health.
Which is better, a 3kW or 7kW home charger?
To recap, 3. W car chargers, or any type of 3kW home EV chargers, may not be the best solution for those who want a future-proof EV charging unit at home. In our opinion, a 7kW charger is better than a 3. W EV charger for home EV charging as it charges twice as fast and provides more flexibility for the future. One of the main advantages of charging an EV at home is that it is generally cheaper than charging at a public station. According to a 2017 report, a person charging an EV at home pays an average of $0. Wh, while a public charging station costs an average of $0. Wh1.
