Outdoor power supply charging temperature above 50 degrees

To maintain optimal performance and allow people to recharge their cars without worrying they'll become stranded in very hot or cold weather, electric charging stations should have a wide operating temperature power supply. Communications equipment often requires a ruggedized enclosure that does not always allow for adequate ventilation.

Some applications may require ambient operating temperatures as low as -40 degrees Celsius and as high as +85 degrees Celsius, or an even wider range. A number of factors can influence the ambient temperature that a power supply is subjected to in a given application, including the following:

Typical commercial power supplies are specified to support their full rated load over an ambient temperature range from zero or minus 25 degrees Celsius to around 50 degrees Celsius, and they may derate to 50% load at 70 degrees Celsius.

Batteries can be discharged over a large temperature range, but the charge temperature is limited. For best results, charge between 10°C and 30°C (50°F and 86°F). Lower the charge current when cold. Nickel Based: Fast charging of most batteries is limited to 5°C to 45°C (41°F to 113°F).

Charging at extreme temperatures can cause permanent damage: Charging batteries outside their recommended temperature range can lead to issues like lithium plating, gas buildup, venting, or even case cracking, especially in lithium-ion and lead-acid chemistries.

Depending on the application, a power supply with a wide operating temperature range may provide better reliability and a longer operating lifetime, prevent the need for a cooling fan or other special design consideration for thermal management, and reduce the overall cost of your system.
