Problems solved by technology

However, this kind of battery has poor low-temperature discharge capacity, does not meet the needs of commercial vehicles for low-temperature starting, and cannot continue to supply power for a long time
In addition, the maintenance-free lead-acid battery undergoes repeated charging and discharging, and the voltage fluctuation has the effect of ripple during the charging and discharging process, which will greatly shorten the service life of the maintenance-free lead-acid battery

Abstract

The invention discloses a commercial vehicle composite power supply, and relates to the technical field of vehicle composite power supplies. The commercial vehicle composite power supply comprises a plurality of power supply modules. Each power supply module comprises a super capacitor and a battery; the super capacitor comprises a capacitor main body, and a first positive electrode and a first negative electrode which are arranged on the capacitor main body; the battery comprises a battery main body, and a second positive electrode and a second negative electrode which are arranged on the battery main body, wherein the battery main body is connected with the capacitor main body; the second positive electrode is connected with the first positive electrode, and the second negative electrodeis connected with the first negative electrode; and the battery is a deep discharge battery. The commercial vehicle composite power supply has the advantages of deep discharge and high-current discharge at low temperature, can meet the requirements of long-time power utilization and low-temperature starting of a parked vehicle at the same time, and is high in reliability and long in service life.

Description

technical field [0001] The invention relates to the technical field of vehicle composite power supply, in particular to a commercial vehicle composite power supply. Background technique [0002] With the improvement of people's quality of life, commercial vehicle users also have higher requirements for parking comfort, and devices such as parking air conditioners and parking heaters for cab cooling and heating have appeared on the market. [0003] When the parking air conditioner or parking heater is used, it needs to be powered from the power supply of the commercial vehicle. At this time, if the engine is used for power supply, too much chemical fuel will be consumed and the cost will be high. If the maintenance-free lead-acid battery is used as the power supply for the parking air conditioner or parking heater, the maintenance-free lead-acid battery has a relatively large discharge power. However, this type of storage battery has poor low-temperature discharge capability...
