Abstract

The invention provides a battery pack serial connection device and a control method thereof. One end of a first switch is connected with a positive output end of a first battery pack; the other end ofthe first switch is connected with one end of a resistor; the other end of the resistor functions as a positive output end of a driving insert part; main positive switches are connected in parallel to two ends of the first switch and the resistor; second switches are serially arranged inside the first battery pack; high and low level ends of the second switches are respectively used as positive and negative output ends of serial insert parts of the first battery pack; one end of a main negative switch is connected with the negative output end of the first battery pack; the other end of the main negative switch functions as a negative output end of the driving insert part; one end of a rapid recharge positive switch is connected with a positive output end of a second battery pack; the other end of the rapid recharge positive switch functions as a positive output end of a serial insert part of second battery pack; one end of a rapid recharge negative switch is connected with a negativeoutput end of the second battery pack; the other end of the rapid recharge negative switch functions as a negative output end of the serial insert part of the second battery pack. By adopting the battery pack serial connection device and the control method thereof, rapid electric connection of battery packs can be achieved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a battery pack series connection device and a control method thereof. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. Affected by traditional car driving habits, the requirement for long driving range of electric vehicles has gradually become a mainstream trend. For example, the Tesla Model-S long driving range version has a maximum pure electric driving range of nearly 500 kilometers. 400km electric car. [0003] Electric vehicles provide kinetic energy through the battery pack (Battery Pack) configured on it. At present, electric vehicles have two conflicting problems of range anxiety...
