How many kW to charge a bZ4X?

At a glance, the bZ4X can draw up to 150 kW from a DC fast charger and about 6.6 kW from a standard AC charger. In some markets there may be variations or optional upgrades, but these are the typical figures you’ll encounter. This article explains what those numbers mean for charging speed, when to use which option, and what to expect in real-world planning.

Charging power by mode

Understanding the two main ways to charge helps set expectations for speed and planning.

DC fast charging

When connected to a DC fast charger (CCS), the bZ4X can draw up to 150 kW at peak. Real-world speeds depend on battery state of charge, temperature, and the charger itself.

• Peak charging power: up to 150 kW (DC fast charging).


• Factors that affect speed: battery temperature, current state of charge, and how long the car has been charging.


• Charging curve: power tapers as the battery nears full; the fastest gains typically occur from low to mid SOC, with diminishing returns near 100%.

In practice, a strong DC fast charger can deliver a brisk top-up, but expect tapering as you approach full capacity.

AC charging

On-board AC charging is typically limited to about 6.6 kW in most markets, designed for home or workplace plugging. Some regions may offer variations or options that support different levels.

• Typical on-board AC rate: around 6.6 kW (240V, common residential setup).


• Home charging implications: a full day’s charge is common, making overnight charging convenient.


• Phase availability depends on region and vehicle configuration.

AC charging provides everyday practicality, while DC fast charging serves trips or time-crunched recharges.

Practical charging times and planning

Times vary with battery size, temperature, and charger availability. The bZ4X’s battery capacity sits in the mid-60s to low-70s kWh range depending on trim and market, which influences observed speeds.

• DC fast charging (peak ~150 kW): roughly 20–35 minutes to move from 0% to about 80%; 0–100% can take roughly 40–60 minutes due to tapering near full.


• AC charging (6.6 kW): a full charge from empty typically takes about 10–12 hours, depending on exact battery size and the home power setup.

For daily use, rely on AC charging at home or at work for convenience, and reserve DC fast charging for longer trips or when you need a quick top-up on the road.

Summary

The bZ4X supports up to 150 kW DC fast charging and about 6.6 kW AC charging, with real-world times influenced by temperature, battery state of charge, and the specific charger. Use DC fast charging for long trips and AC charging for daily routines to optimize your travel and charging schedule.

How fast is level 2 charging Toyota bZ4X?

Level 2 charging (at 32A): Going from Low Light to 100% can take ~9.5 hours, which results in an average charging rate of ~20 miles/hour. DC Fast Charging for current models in ideal conditions: In AWD models, going from Low Light to 80% can take 35 minutes, which results in an average charging rate of 5 miles/minute.

How many kWh does it take to charge an i4?

The amount of energy to charge a BMW i4 varies by model, but the total battery capacity is approximately 67.167.167.1 kWh to 83.983.983.9 kWh. A full charge depends on the charger type: a Level 2 AC charger (up to 11 kW) can fully charge the battery in about 8.25 hours, while a DC fast charger can add around 90 miles of range in just 10 minutes. 
Battery capacity

• i4 eDrive35: Approximately 67.167.167.1 kWh
• i4 eDrive40/M50: Approximately 81.581.581.5 kWh usable / 83.983.983.9 kWh gross 

Charging with different chargers

• Level 1 (120V): A full charge takes around 100 hours, and adds roughly 1.6 kW per hour. 
• Level 2 (240V, 11kW): A full charge takes about 8.25 hours. 
• DC Fast Charging:
  • With a 50kW charger: A 10% to 80% charge takes about 36-48 minutes. 
  • With a high-powered charger (up to 200kW+): A 10% to 80% charge takes just over 30 minutes. 

How many kW to charge my EV?

The amount of kW needed to charge an EV varies from about 1.9 kW for a basic Level 1 charger to 50 kW or more for DC fast chargers. Common Level 2 home and public chargers typically range from 3.3 kW to 19.2 kW, with a popular 7.2 kW unit being able to provide about 25 miles of range per hour. The required power depends on the charging level, the specific charger, and the vehicle's capabilities. 
Charging levels and power

• Level 1: Uses a standard 120V120 cap V120𝑉 wall outlet and provides about 1.91.91.9 kW. This is the slowest option. 
• Level 2: Uses a 240V240 cap V240𝑉 outlet, similar to what is used for a clothes dryer. 
  • Common speeds are between 3.33.33.3 kW and 19.219.219.2 kW. 
  • A common 7.2 kW charger can fully charge many EVs in about 8 to 10 hours. 
  • This level adds approximately 25 miles of range per hour with a 7.2 kW charger. 
• Level 3 (DC Fast Charging): Found at public charging stations. 
  • These chargers deliver power at a much higher rate, typically from 505050 kW to 350350350 kW. 
  • They can provide a full charge in 10 to 20 minutes. 

Factors that determine charging power

• Charging station: The charger's maximum output is the primary factor, especially for public DC fast chargers which can deliver power much faster than home chargers. 
• Vehicle's onboard charger: The vehicle's own charging system has a maximum charging rate. Even if you use a powerful 19.2 kW charger, your car will only accept power up to its own limit, which might be lower. 
• Battery state of charge: The car's battery management system can slow down charging as the battery gets full to protect it from damage, so charging is often fastest when the battery is near empty. 

How many kWh to charge a bZ4X?

A full charge of a Toyota bZ4X with its 71.4 kWh battery requires approximately 71.4 kWh of energy, but the amount of energy needed will vary based on the charging speed, the battery's current state, and charging efficiency losses. For a complete 0-100% charge, it can take as little as 9.5 hours with a Level 2 (240V) charger or over 50 hours with a Level 1 (120V) outlet. 
Charging from empty to full

• Level 2 (240V): Approximately 9.5 hours
• Level 1 (120V): Over 50 hours 

Charging speeds and times

• Level 2 (7.6 kW): About 11 hours to fully charge. 
• DC Fast Charging (150kW): Can charge from 10% to 80% in as little as 35 minutes under ideal conditions. 
• DC Fast Charging (150kW) 0-100% : This is not recommended due to the slow down after 80%, but a full charge will still take a considerable amount of time after the initial 35-minute 10-80% charge. 

Important considerations

• Battery size: The 2024 model has a 71.4 kWh battery. 
• Charging losses: There will be some energy loss during charging, so a full 71.4 kWh battery will require more than 71.4 kWh of energy from the wall. 
• Charging curve: DC fast charging speeds slow down significantly after about 80% charge.
