The summary shows that the battery and body integrated structure includes a body and a power battery pack. The body includes two sill beams. The two sill beams are spaced apart along the left and right directions of the vehicle. Each sill beam is provided with a battery pack installation part. Through the above technical solution, the top of the battery pack case is integrated with a cross beam. The cross beam can strengthen the main body of the case and improve the stiffness and side impact force transmission performance of the battery pack case. The top of the main case serves as a floor panel, which is conducive to improving the performance of the battery pack case. The degree of integration of the vehicle can reduce the weight of the body structure, achieve lightweighting of the vehicle, and increase the vehicle’s cruising range.

With the upgrading and iteration of power battery technology and new energy vehicle manufacturing technology, car companies have gradually shifted from CTP (battery large module or module-less technology) to CTC in the choice of power battery installation. / CTB (battery chassis/body integration technology). As a new generation of battery system technology, CTC realizes the integrated design of batteries, chassis and lower body, etc., simplifies product design and production processes, improves vehicle stiffness and space, and increases battery capacity and driving range while reducing costs. Compared with CTP moduleless technology, CTC mainly integrates the floor panel and the battery pack upper cover into one, reducing the gap between the two and the parts required for connection, simplifying the production steps, and the battery core is both for the whole It is the source of kinetic energy for the car and is also a structural member that increases the rigidity of the chassis/body.

The summary compiled as follows:

 Upon receiving the charging request message sent by the vehicle to be charged, the charging device determines the target parking space where the vehicle to be charged is currently parked;

 Determine the target induction coil corresponding to the target parking space from the coil array;

 Position the electric energy receiving coil installed on the vehicle to be charged through the target induction coil to obtain the target position of the electric energy receiving coil;

 Use any idle electric energy transmitting coil located at the preset place as the target electric energy transmitting coil, and move the target electric energy transmitting coil to the target position so that the vehicle to be charged can be wirelessly charged through the target electric energy transmitting coil and the electric energy receiving coil.

Xiaomi Auto stated that this patent avoids the driver’s need to constantly adjust the parking position of the vehicle to be charged to achieve precise alignment of the target power transmitting coil and the power receiving coil, thereby reducing the driver’s parking operation complexity and improving the vehicle’s parking freedom. Spend.

Xiaomi announced in 2021 that it will invest US$10 billion to build cars over the next 10 years. Since then, news about Xiaomi cars has emerged one after another. Lu Weibing, partner and president of Xiaomi Group, revealed last month that Xiaomi’s car manufacturing is progressing very smoothly, and some recent progress has even exceeded expectations.

Lu Weibing said that Xiaomi’s actual investment in automobiles is even greater. Xiaomi is making long-term layout of automobiles with the goal of entering the top five in the world, doing full-stack self-research, and building its own automobile factory, so the cash flow is The investment is higher than the disclosed figure.

In addition, Lu Weibing also said that Xiaomi Motors will maintain its mass production target in the first half of 2024 and will not change.

The abstract shows that the method includes: when the vehicle is in the drift mode open state, obtaining the slip rate level and steering information of the vehicle and the current vehicle speed of the vehicle, determining the target drift parameters, and the target drift parameters include the target yaw rate; according to the current vehicle speed The actual yaw rate and the target yaw rate determine the amount of steering compensation; according to the amount of steering compensation and steering information, determine the front axle torque, rear axle torque and rear wheel braking torque of the vehicle, so as to control the drifting of the vehicle. During the process, the steering compensation is performed by controlling the power steering motor according to the steering compensation amount and vehicle speed.

This disclosure reduces the dependence of vehicle drift on the driver, and determines different drift parameters according to different steering and vehicle speeds of the vehicle, so as to realize drift in different states.

Recently, near the Xiaomi Technology Park, some netizens took photos of a suspected Xiaomi car. The body is covered with camouflage paint, but it looks like a coupe from the model. It looks a bit like a Porsche Panamera and is equipped with lidar. According to previous media reports, the internal codename of Xiaomi’s first car is MS11, which may be equipped with 800V technology and a 260kW electric bridge. It is expected to be officially mass-produced in January 2024. It is reported that the first engineering vehicle has already rolled off the assembly line on September 28, 2022.

The Xiaomi car project has settled in the Beijing Economic and Technological Development Zone. The Xiaomi car headquarters base, sales headquarters, and R&D headquarters will be built. A vehicle factory with an annual output of 300,000 vehicles will be built in two phases, of which the first and second phases will have a production capacity of 150,000 vehicles, It is expected that the first car will roll off the production line and achieve mass production in 2024.
