Brake Energy Regeneration offers a dual benefit: during acceleration, the alternator is deactivated so the entire power output of the engine is directed to dynamic performance. During braking, the alternator is activated and makes efficient use of engine power output to charge the battery - instead of it being dissipated as heat.
