Connecting car alternators in parallel can lead to synchronization issues due to their varying output frequencies and the potential for short circuits if the alternators are not electrically isolated. While it is theoretically possible to connect two alternators with the same specifications, each must have its own regulator and be isolated to prevent feedback interference. The discussion highlights the need for careful design, especially when charging battery packs, as improper connections can result in significant safety hazards. A dedicated alternator for each battery is suggested to optimize charging and battery lifespan, particularly in applications like electric vehicles. Overall, while the idea may seem feasible, it requires meticulous planning and safety precautions to avoid catastrophic failures.
