Four Charging Methods to Overcome EV Range Anxiety

Electric vehicles currently face three major issues: short range, few charging stations, and long charging times, which cause range anxiety among many car owners. How can we alleviate this anxiety? Let’s learn about the various charging methods: supercharging, fast charging, slow charging, and portable charging.

Charging Method 1: Supercharging

 

Since charging speed is directly related to the power of charging stations, why not set a small goal to double the power of fast-charging stations? Hence, supercharging stations were born. A typical example is Tesla’s Supercharger, which has twice the power of other fast chargers, allowing vehicles and batteries to handle the high power.

Media tests have shown that after Tesla’s Supercharger upgrade, the charging efficiency has significantly improved. Comparing Tesla’s V3 to V2 Supercharger, the time taken to charge from 3% to 55% was reduced by 35%, and the time to charge from 3% to 90% was reduced by 16%.

Max Power Time for 3%–55% Time for 3%–90%
V2 Super Charger 120 KW 20 Mins 44 Mins
V3 Super Charger 240KW 13 Mins 37 Mins
V3 Saves time compared to V2 35% 16%

 

Supercharging Aspects Advantages Disadvantages
Charge Speed Fast charging
Management & Accessibility Well-managed without occupancy issues
Cost High-cost, expensive charging prices
Vehicle Compatibility Requires vehicle compatibility, not universal

At present, not all the brands of electric vehicles support supercharging. But some new EVs made in 2024 will be more and more supercharging compatible with 800V.

 

Charging Method 2: Fast Charging

 

Fast charging serves all types of vehicles well and is, besides home charging, an essential method.

Traits of fast charging:

Fast-charging stations are usually large, box-like structures.

Some multi-gun fast chargers dynamically allocate power. Want to charge quickly? Use one charger per car.

The “slender” ones are split-type fast chargers, with a “big box” or even a “big house” nearby:

Fast Charging Aspects Advantages Disadvantages
Charging Time Relatively quick charging
Compatibility Universally compatible with all vehicles
Cost Competitive pricing due to multiple providers
Standards Variable site and management standards
Investment & Popularity High investment, difficult to rapidly popularize

 

Miles Energy offers high-quality and stable fast EV chargers from 30 kW to 240 kW.  They are compatible with CCS1, CCS2, and CHAdeMO standards.

Charging Method 3: AC Slow Charging

 

The “star” of the slow charging process is the car’s onboard charger, playing only a connecting role—plugging AC power into the vehicle. Hence, slow chargers are small and light, containing mainly control and safety devices.

Standard slow chargers come mainly in two power ratings: 3.5 KW and 7 KW, compatible with all cars. But the actual charging power also depends on the vehicle. As car batteries grow larger, many new vehicles support 11KW and 22KW AC slow chargers to increase charging speeds.

Tesla’s charging stations cannot charge other brands’ vehicles due to software restrictions, but Tesla vehicles can use all charging stations. Now Tesla has announced to opening of their charging network to other brands. Soon, NACS will unify the charging standards in North America.

Slow Charging Advantages Slow Charging Disadvantages
Safe, and can fully recharge batteries Slow charging, relatively high price
Low investment, easy to popularize High cost of parking during charging
Does not occupy space or parking spots N/A

 

Miles Energy offers the latest AC EV charger with the OCPP1.6J communication protocol, giving our customers flexible OEM and ODM services. They already passed TUV CE certification and UL certification.  Contact us for more information.

Charging Method 4: Portable Charging

 

Portable charging is also a type of slow charging, similar to using a slow charger. The difference is that portable EV chargers can be carried and used anywhere. But for safety, they have even lower power.

Portable Charging Advantages Portable Charging Disadvantages
Convenient, charge anywhere Extremely slow, time measured in days
Can fully recharge Some safety hazards

Conclusion:

 

Electric vehicles face key tech challenges. Solving these will make clean energy use more convenient and reduce anxiety. Superchargers are fast and efficient, while portable chargers offer flexibility. Each type addresses different user needs. We should use what we have wisely, learn about charging, drive better, and back the build of better chargers.

Let’s support EV tech progress. This will lead to overcoming EV hurdles soon. Together, we can push new energy vehicles forward for a cleaner world. Let’s unite for a zero-pollution future.
