What are the main manufacturers of electric vehicle chargers? Talk about some common problems and general solutions

Recently, I talked to my friends about buying a tram, and several of them mentioned the hassle of charging. Either I couldn't find the charger, or when I found it, I found that it couldn't be used, or I waited in a long queue. We have to talk about electric vehicle charger manufacturers. There are many brands on the market that make electric vehicle chargers, including those specializing in public operations, those with a background in the power grid, and those built by car companies themselves. Each family has their own ideas, but there are still many problems in practical use.

A common issue is that many electric car chargers choose cars. Some old DC chargers cannot match the newly released 800V high-voltage models, and their charging power cannot keep up. They may have fast charging but have turned into slow charging. Another issue is that the failure rate of chargers is relatively high, with screens crashing, gun heads getting stuck, network connectivity issues, and maintenance not keeping up. A charger that breaks may not be repaired for a month. In addition, the installation of private chargers in the community is also stuck at the property management's checkpoint. The old community has insufficient capacitors and is not allowed to install them; Some new residential areas do not provide wiring.

From an operational perspective, many stations have low utilization rates. Either the position is skewed, or the fuel truck occupies space, or the power distribution of the charger is unreasonable - when two cars are charged at the same time, the power is evenly distributed and both are charged slowly. Behind this is actually the manufacturer's plan that did not refine the scheduling logic.

Some manufacturers are trying to improve in response to these situations. For example, Hongjiali(HG Power) has an integrated DC charger that dynamically adjusts power distribution. When two cars are charged together, the system will automatically allocate power based on the remaining battery capacity and demand of each car, so that both cars will not be slow. This charger is also compatible with vehicles on high-voltage platforms, reducing the embarrassment of "not being able to charge". In addition, to address the issue of insufficient capacity in residential areas, Hongjiali(HG Power) has launched an orderly charging management plan that can be linked to the property's electricity load. The charging power can be increased late at night or during low electricity periods, and automatic current limiting can be implemented during the day. This will reduce the property's concerns and increase the pass rate of owners installing charging devices.

Of course, no solution is perfect, it depends on the actual implementation effect. Choosing an electric car charger manufacturer, in other words, is to see if it can fix the faulty charger faster, make the car charge smoothly, and not let the owner search for a usable charger all night long. If you are planning to invest in charging stations or communities to install chargers in bulk, you may want to take a look at the application cases of this manufacturer in different scenarios, compare the failure rate and after-sales response speed, and you will have a rough idea.
