Title:

BATTERY SYSTEM OF VEHICLE, CHARGING AND DISCHARGING METHOD, AND VEHICLE

Document Type and Number:

WIPO Patent Application WO/2020/244465

Kind Code:

A1

Abstract:

A battery system of a vehicle, a charging and discharging method, and a vehicle. The battery system of a vehicle comprises an energy storage device (1) and a direct current charging and discharging interface (2) connected to each other. The energy storage device (1) comprises a first battery pack (17) and a second battery pack (18). A first inter-battery switch (11) and a second inter-battery switch (12) are provided between adjacent battery packs. An incoming line end (111) of the first inter-battery switch (11) is connected to a first electrode of the first battery pack (17). A first outgoing line end (112) of the first inter-battery switch (11) is connected to a first electrode of the energy storage device (1). A second outgoing line end (113) of the first inter-battery switch (11) is connected to a first outgoing line end (112) of the second inter-battery switch (12). A second outgoing line end (113) of the second inter-battery switch (12) is connected to a second electrode of the energy storage device (1). An incoming line end (111) of the second inter-battery switch (12) is connected to a second electrode of the second battery pack (18). A first electrode of the direct current charging and discharging interface (2) is connected to the first electrode of the energy storage device (1). A second electrode of the direct current charging and discharging interface (2) is connected to the second electrode of the energy storage device (1). The invention solves the problem in which a battery pack of a high-voltage platform cannot be charged by means of a low-voltage charging pile.
