Comparing Portable and Wall-Mounted EV Chargers: Pros and Cons

Caring for the battery of your electric vehicle (EV) is essential to safeguard your investment. Over the past few decades, our society has become increasingly dependent on battery-powered electronic devices and machines. From smartphones and wireless earbuds to laptops and now EVs, these devices have become an integral part of our daily lives. However, the importance of careful use and maintenance of EV batteries cannot be overstated, given that EVs represent a significant financial investment and are designed to have a much longer lifespan than smartphones or laptops. Using an AC charger can potentially extend the lifespan of your battery compared to using a DC charger. Additionally, AC chargers come in both portable and wall-mounted variants. In today's blog, we will analyze the pros and cons of these options, with the hope of providing you with valuable insights.

1. Lower Charging Speeds: Portable chargers often have lower power output compared to their wall-mounted counterparts, resulting in longer charging time period. Currently, most Level 2 portable chargers have a power rating of 3.5 kW. For a Tesla with a 60 kWh battery, it would take approximately 17 hours to go from zero to a full charge using such portable charger.

2. Faster Charging: Wall-mounted chargers usually offer higher power output, which can significantly reduce the charging time period compared to portable chargers. Currently, the minimum power rating for wall-mounted chargers is 7 kW. For a Tesla with a 60 kWh battery, it would only take 8 hours to go from zero to a full charge using such a charger. Other faster charging options are also available.

In conclusion, the choice between a portable and a wall-mounted EV charger depends on the specific needs and lifestyle of the EV owner. TECOPHASE recommends that if there is available installation space at home, you should definitely choose to install a wall-mounted charging station for your electric vehicle. This way, you will enjoy a very convenient and cost-effective experience, often benefiting from lower electricity rates during nighttime charging. However, since widespread adoption of charging stations may take some time, it is also advisable to purchase a portable charger to keep it in your car as a backup. Portable chargers do not require installation, and their prices are relatively affordable, making the decision not overly difficult. This way, you can enjoy the advantages of having both types of chargers.

Wide Selection of Wall Mount Power Supplies from APS

 
Wall Mount Power Supplies are a type of external power supply, enclosed in a non-flammable plastic enclosure with an AC plug that mechanically mounts the power supply to the AC outlet.  A DC output lead connects the wall mount power supply's DC output voltage to the device being powered.  APS Wall Mount Power Supplies feature Universal AC Input for operation over a 90~264VAC range. 

All APS wall mount power supplies have been qualified to meet internation safety standards for ITE / Industrial applications (IEC/EN/UL -1) and/or Medical application (IEC/EN/UL -1).  Additional energy standards relating to no-load input-power limitations and operational efficiency have been adopted over the years and all APS power Supplies comply with DoE (Level VI) | EU ErP 5 standards, ensuring your devices will comply with any energy / efficiency requirement around the globe.

Common names other than Wall Mount Power Supplies include wall plug, AC adapter, plug-in adapter, adapter block and wall wart. Wall Mount Power Supplies for battery-powered equipment may be described as chargers or rechargers.  Wall Mount Power Supplies are used with devices that cannot afford the size / heat or safety compliance challenges required of internal power conversion circuits. Wall Mount power supplies are used to power devices directly or to both charge batteries in addition to powering the equipment. Use of an external power supply allows portability and makes it unnecessary to produce equipment for use only with a specified power source; the same device can be powered from 120 VAC or 230 VAC mains, vehicle or aircraft battery by using a different adapter.

Advantages of Wall Mount Power Supplies include:

• Safety – Wall Mount power supplies can free product designers from safety issues. Most devices using Wall Mount power supplies utilize voltages less than 56 VDC which meet SELV standards, making the device safe and freeing it from compliance to products that draw power from AC Mains, which are considered unsafe.
• Heat reduction – Converting AC voltage to a DC Voltage required by devices for operation consumes space and generates heat.  Wall Mount power supplies allw for device miniaturization and keeps the generated heat out of the device, improving reliability and longevity of the device.
• Electrical noise reduction – Power Conversion from switching power supplies can generate unwanted EMI / raidiated noise. Wall Mount power supplies keep potential noise from entering the device, providing only a clean DC voltage to the device.
• Ease of replacement – Wall Mount power supplies  can be replaced quickly by a user without the need to have the powered device repaired.
