The utility model relates to a be applied to car start stop system and can realize energy recuperation's ultracapacitor system hybrid power source, negative pole end and the lead acid battery's of ultracapacitor system module the negative pole end negative pole end that links to each other and constitute the hybrid power source wherein, the positive terminal of ultracapacitor system module are the positive terminal of hybrid power source, its characterized in that: between the positive terminal of ultracapacitor system module and lead acid battery's the positive terminal parallelly connected discharge the current -limiting unit with the current -limiting unit charges, the current -limiting of discharging unit is established ties with the current limiter by the diode with the current -limiting unit that charges and is constituteed, the current -limiting unit current limiter that discharges of the current -limiting of discharging unit is connected with lead acid battery's positive terminal with the current -limiting unit diode that charges of the current -limiting unit that charges, discharge current -limiting unit diode and the current -limiting unit current limiter of current -limiting unit of charging of the current -limiting of discharging unit are connected with the positive terminal of ultracapacitor system module. It can solve the battery short -lived problem that big current discharge leads to in the frequent start -up course of car to energy recuperation when realizing the automobile brake.
