From May 22nd to 24th, the 2024 Third Shanghai International Charging Pile and Battery Swapping Station Exhibition was held in Shanghai. The expo brings together domestic mainstream charging piles and related supporting companies. Different from previous such exhibitions, many companies have displayed low-power DC charging piles this time, ranging from 7kW-40kW.

DC piles have an absolute advantage due to their "fast charging speed and high efficiency". In places such as shopping malls and scenic spots, users stay for 1-3 hours. Ordinary AC piles are too slow, and fast charging is wasteful. Low-power DC is just enough, and several more fast charging piles can be installed. For scenarios such as shopping malls, high-speed service areas, scenic spots and parks, etc. for short-term power replenishment, small wall-mounted (pillar) fast DC charging piles, mainly 20kW, 30kW and 40kw small DC charging piles, are becoming increasingly popular. (Take 30kw DC pile as an example)

1. Strong stability

The 30KW DC charging pile provides DC output with very stable voltage and current. The charging process causes very little loss to the battery, which can extend battery life to a certain extent.

2. High charging efficiency

The 30KW DC charging pile has high efficiency. It can perfectly convert the alternating current of the power grid into the current and voltage required by the vehicle. It has a fast charging speed and is not prone to energy loss.

3. High safety

The AC charging pile has multiple protection functions such as over/under-voltage protection, over-current protection, overload/short-circuit protection, grounding protection, over-temperature protection, lightning protection, etc. It also has relay adhesion detection, electric energy measurement and other functions, and its performance is safe and reliable.

4. Easy to install and maintain

The 30KW DC charging pile is smaller than a normal fast charging pile, is easy to install, has high space utilization, and is easy to maintain. It can be used in underground garages, parking lots and other places.

5. Low cost

The equipment cost of the 30KW DC charging pile is lower, so the installation cost is also lower. In addition, the electricity bills generated by home charging piles are lower, and users’ travel costs are greatly reduced, which greatly meets user needs.

In response to this market demand, Gangu QGKZD-3N/QGKZD-3M/QGKZD-3D has become the "king hot" product in the small DC charging pile motherboard market due to its stable performance, simple assembly, and high space utilization. In the later stage, the output power can be increased by adding charging modules, with a wide range of options, complete charging methods, and high safety performance.

1. Small DC single charger main control board (stand-alone version) QGKZD-3D

Product introduction:

Size: 169*122*30mm

It is mostly used for DC portable charging piles. It can also be used for wall-mounted and column-type DC single-charging charging piles (stand-alone version) with a power of less than 60kw. A single gun can control up to 8 modules, and the charging power can be flexibly increased or decreased later.

2. Small DC single charger main control board (operation version) QGKZD-3N

Product introduction:

Size: 150*141*30mm

It is mostly used for DC portable charging piles. It can also be used for wall-mounted and column-type DC single-charging charging piles (operational version) with a power of less than 60kw. A single gun can control up to 8 modules, and the charging power can be flexibly increased or decreased later.

3. Small DC single charger main control board (integrated version) QGKZD-3M

Product introduction:

Size: 189*110*22mm

It is mostly used for DC portable charging piles, but can also be used for wall-mounted and column-type DC single-charging charging piles with a power of less than 60kw (integrated version). The built-in insulation detection module is used to measure insulation resistance. A single gun can control up to 8 modules, and the charging power can be flexibly increased or decreased later.
