[MaStr]

• honor battery limits
• only calculate needed recharge energy if charging is possible
• add some tests

Pull Request Overview

Optimizes charge rate calculation logic by honoring battery limits and improving energy calculation efficiency. The changes only calculate required recharge energy when charging is actually possible, preventing unnecessary computations when the battery is at or above charging limits.

• Only calculate required recharge energy when charging is possible based on SOC limits
• Limit required recharge energy to available charging capacity
• Add comprehensive test coverage for charging scenarios and edge cases
