Different Electric Car Charging Modes

Mode 1 EV Charger

Mode 1 charging technology provides a simple way to charge an electric vehicle (EV) at home using a regular household outlet and a basic extension cord. However, this method lacks any built-in protection against DC currents, making it a less safe option. Mode 1 charging relies on alternating current (AC) at up to 16 amps through standard domestic or industrial sockets, but it does not incorporate any communication or protection mechanisms with the vehicle. This mode is generally suitable for light EVs, such as electric motorcycles.

Intonepower does not support or recommend Mode 1 technology for EV charging, as it lacks safety protections.

Mode 2 EV Charger

Mode 2 charging includes a specially designed cable that integrates shock protection against both AC and DC currents. Unlike Mode 1, where a regular cable is used, Mode 2 cables provide built-in safety features to guard against electric shocks. This makes Mode 2 one of the most popular options for charging EVs today.

With Mode 2, charging occurs via an AC connection through a standard or industrial socket, with an in-cable control box (ICCB) providing power regulation and safety monitoring, including differential protection. Mode 2 charging is commonly used in domestic and industrial settings but is typically not recommended for public or third-party charging.

Mode 3 EV Charger

Mode 3 charging is designed for dedicated EV charging stations or home-installed wall boxes that ensure AC and DC shock protection. In this mode, the charging cable is integrated with the wall box or station, so a separate cable is not required with the EV. Mode 3 has become the preferred option for EV owners due to its robust safety and convenience.

One option for Mode 3 charging is the Intonepower 11-22kW three-phase AC EV home charger. This home charger provides fast, efficient charging with three-phase power, allowing EVs to charge up to 22kW, perfect for those looking for higher power and safety in a home-installed charger. With a Type 2 plug and built-in safety features, it can connect with the vehicle seamlessly, managing both differential and thermal protection.

Mode 3 enables the EV to communicate with the charging equipment using a pulse-width modulation (PWM) protocol. The station provides comprehensive safety functions like differential and thermal protection, allowing charging up to 63 amps (about 44 kW) in both private and public spaces using a Type 2 charging plug.

Mode 4 DC Fast Charger

Mode 4 charging, known as "DC fast charging," delivers high-speed charging for EVs, with power levels ranging from portable 5kW units up to 150kW, and even 350 to 400kW in newer standards. Mode 4 uses a direct current (DC) charging point equipped with essential control and protection functions, allowing for ultra-fast charging rates.

Depending on the charging setup, a Mode 4 charger can use a Type 2 plug for up to 80 amps or a Combo plug (CCS) for currents up to 200 amps, achieving power levels as high as 170 kW.

In summary, Intonepower recommends Mode 2, 3, and 4 chargers for secure and efficient EV charging, catering to a range of needs from domestic to high-speed public charging environments. For those interested in high-power, safe home charging solutions, Intonepower's 11-22kW three-phase AC EV home charger is an excellent choice.
