WHAT’S DC FAST EV CHARGER

DC Fast EV Charger directly output DC power to charge the EV car battery.

It can be stalled on the wall or pole, installed in public buildings ( shopping malls, hospitals or public parking lots, etc.), road, charging stations or residential area(3phase) . It can charge different types of electric vehicles based on different voltage levels. Charge different types of electric vehicles. The input terminal of the charging pile is connected to the AC power grid, and the output terminal is equipped with a charging plug for charging electric vehicles.

What is the DC Fast EV Chargers?

 The power is large (30kw, 40kw, 60kw, 120kw, 200kw, or even higher), and the charging speed is faster. Therefore, it is generally installed next to the express highway charging station, Service stations, commercial car parks, shopping centers.

WHAT TYPES OF DC FAST CHARGING ARE THERE?

There are four main kinds of DC charger connectors used worldwide: Combined Charging System (CCs), GB/T, CHAdeMO, and Tesla Superchargers.

There are two types CCS connector, CCS1 which is used in North America, and CCS2, which is used in Europe. CHAdeMO is for Japanese brand electric vehicles.

GB/T is the standard connector for the Chinese brand EV Car, and Tesla’s Supercharger works with all Tesla vehicles worldwide except in the EU.

HOW FAST IS DC FAST CHARGING?

Different types of electric vehicles(hybrid or Pure Electricity), Varying battery capacities, DC charger power outputs and these several factors that can influence charging speed.

it isn’t easy to give an answer to how fast DC charging is. But we can provide an estimate of how many miles of range a DC fast charger can deliver to an electric vehicle within 60 minutes based on the output power of the DC charger and the kWh per 100 miles of the average EV, which is 34.6.

30 kw 87miles (139 KM)/hour

50 kW 145miles (232 KM)/hour

100 kW 289miles (462 KM)/hour

120 kW 347miles (555 KM)/hour

150 kW 434miles (694 KM)/hour

180 kw 520miles (832 KM)/hour

250 kW 723miles (1157 KM)/hour

350 kW 1012 miles (1619 KM)/hour

IS DC FAST CHARGING BAD FOR A BATTERY?

The essence of fast charging is to store direct current directly into the battery, and the power of direct current is very large, the voltage during charging is about 400-500V, and the current is about 20-30V. During the charging process, a large number of electrons continue to accelerate from the positive electrode to the negative electrode of the battery. This process will generate very high heat, and due to the increase in temperature, the semi-permeable membrane on the surface of the negative electrode of the battery (similar to the existence of a separation wall, will Separate the battery material and electrolyte to prevent it from reacting) rupture. Meanwhile, a reaction will occur, causing foreign matter on the motor and decomposing the electrolyte. Over time, the battery will gradually decrease.
