Filling a 680 liter 3000psi tank (one of the 5-foot tall ones) from even the most powerful hydraulic compressors you can use at home will take you between 10 and 45 minutes. But one of those tanks is not likely to get you a useful amount of range, so you will need to double or triple that amount of time.

And that method of energy storage is only 60% efficient. A good deal of the compressor output is converted to heat, which sinks out of the tank over time. So you're using 40% more electricity and you're still probably getting less range. Which is just as affected by temperature as SLA batteries.
