As of my last knowledge update in September 2021, the Volvo ECR25 is a compact excavator. The charging time for electric vehicles, including electric construction equipment like the ECR25, can vary based on factors such as the battery capacity, the type of charger being used, and the state of charge of the battery when you begin charging.

For electric construction equipment, the charging time can be influenced by the size of the battery pack and the charging power of the charging station. Charging times could range from several hours for a near-empty battery to potentially a full workday or longer for a complete charge.

It's important to note that there might have been developments or changes in technology since my last update, so I recommend checking with Volvo or the manufacturer's documentation for the most accurate and up-to-date information regarding charging times for the Volvo ECR25 or any other specific model.
