I. Basic Introduction & Working Principle
1. EV AC Charger
The ev ac charger, also known as an alternating current charging pile, is the most common charging equipment for electric vehicles. It matches the on-board charger of electric cars. The external AC power is transmitted to the vehicle first, and then the built-in rectifier inside the electric vehicle converts alternating current into direct current to charge the power battery.
The mainstream AC fast charger for EVs has relatively stable output power. Most household and conventional AC chargers work with low to medium power. The whole charging process is gentle, with a small current and stable voltage. This charging mode puts less load on the vehicle battery and electronic components. AC charging equipment has a simple internal structure, fewer core components, and a low failure probability, which is one of its prominent features.
2. DC Fast Charger for Electric Vehicles
Different from AC chargers, the dc fast charger for electric vehicles integrates high-power rectifier modules inside the equipment. It directly converts municipal alternating current into high-voltage and large-current direct current, and transmits power to the vehicle battery. It does not rely on the vehicle’s on-board charger, so it realizes ultra-fast charging.
High-power DC charging equipment is composed of power modules, control systems, heat dissipation devices, and safety protection components. Its internal circuit and control logic are more complex. Due to the large instantaneous current during operation, it has higher requirements for power supply lines, distribution cabinets, and on-site safety protection measures. Meanwhile, users always take the DC fast charger price and the long-term DC fast charger cost into full consideration before purchasing.
II. Core Differences Between AC Fast Charger and DC Fast Charger
1. Charging Speed
Charging speed is the most obvious distinction. A standard AC fast charger for EVs usually has a power ranging from 20kW to 40kW. For a mainstream family electric car with a 60kWh battery pack, it takes 4 to 10 hours to be fully charged. Even high-power AC chargers cannot achieve rapid power replenishment. In contrast, the DC fast charger for electric vehicles generally has a power of 60kW, 120kW or even higher. A 60kW DC charger can charge a regular electric vehicle from 20% to 80% in just 30 to 40 minutes. High-power DC fast chargers can further shorten the charging time to within 20 minutes. It is the ideal choice for users with urgent power supplement demands.
2. Purchase & Installation Cost
Cost is a key factor affecting users’ decisions. The overall price of the EV AC charger and AC fast charger for EV is low. The equipment itself is affordable, and the supporting power distribution facilities are simple. The wiring and construction requirements are not strict, so the total one-time investment is low. The later use and maintenance cost is also very economical.
The DC fast charger price is much higher than that of AC products because of its complex internal structure and high-grade power modules. In addition to the equipment cost, users also need to transform high-voltage power lines, configure special distribution cabinets and build professional heat dissipation systems, which greatly increases the overall DC fast charger cost. Whether for individual users or commercial investors, DC fast chargers require larger upfront capital investment.
