Embodiment 1

[0127] Figure 5 The circuit structure of the battery unboxing subsystem 10 in Embodiment 1 of the present invention is shown. In Embodiment 1 of the present invention, each of the out-of-box control units 102 includes a first high-voltage contactor KM1. Wherein, the first high voltage contactor KM1 has a first main contact and a second main contact.

[0128] Wherein, the first main contact of the first high-voltage contactor KM1 is connected to the fourth connection terminal S4 of the unboxing control unit 102, that is, the first main contact of the first high-voltage contactor KM1 is connected to the battery The first connecting end S1 of the unpacking subsystem 10, that is, the first main contact of the first high-voltage contactor KM1 is connected to the second connecting end S2 of the previous adjacent battery unpacking subsystem 10, that is, the first main contact of the first high-voltage contactor KM1. The first main contact of a high-voltage contactor KM1 is connect...

Embodiment 2

[0150] Figure 8 The circuit structure of the battery unboxing subsystem 10 in the second embodiment of the present invention is shown. In the second embodiment, each of the out-of-box control units 102 includes a third high-voltage contactor KM3. Wherein, the third high voltage contactor KM3 has a fifth main contact, a sixth main contact and a seventh main contact.

Abstract

The invention provides an electric vehicle battery stripping driving system which comprises multiple battery stripping subsystems connected in series. Each battery stripping subsystem comprises a battery pack and a stripping control unit, multiple battery packs are mutually connected in series to form an electric vehicle power battery, each stripping control unit is designed for the corresponding battery pack and connected into a circuit where the battery packs are mutually connected in series, when one battery pack is in a normal state, the corresponding stripping control unit connects the battery pack with other battery packs to form a power battery together, and when the battery pack is in an abnormal state, the corresponding stripping control unit makes the battery pack get away from the power battery on the premise that other battery packs are not affected. According to the electric vehicle battery stripping driving system, on the condition that normal driving of a vehicle is not affected, maintenance for faults and batteries is achieved, it is guaranteed that the faults are handled in time, normal driving of the vehicle is not affected, the service life of the batteries is prolonged, and reliability and safety of vehicle driving are improved.

Description

technical field [0001] The invention relates to the field of electric vehicle control, in particular to an electric vehicle battery out-of-the-box continuous driving system and an electric vehicle using the system. Background technique [0002] Electric vehicle rechargeable energy storage system, also called RESS (Rechargeable Energy Storage System) system, currently used power system lithium battery pack is basically composed of lithium-ion single batteries through different series and parallel groups (single batteries in series To achieve the required voltage, parallel connection to achieve the required capacity), and finally enable the battery pack to provide the energy and power output required by the electric vehicle, thereby driving the motor of the electric vehicle to make the vehicle run. [0003] At present, in electric vehicles, most of the battery packs are connected in series, that is, a single battery first forms a battery pack, and then multiple battery packs f...
