Description

Technical Field

[0001] This utility model relates to the field of new energy battery management technology, and in particular to a new energy vehicle battery management device. Background Technology

[0002] The Battery Management System (BMS) for new energy vehicles is a key technology for monitoring and managing battery packs. Its core functions include real-time monitoring of battery parameters such as voltage, current, and temperature; assessing the remaining charge and health status of the battery; and taking protective measures in case of abnormalities such as overcharging, over-discharging, or overheating to ensure safe battery operation and extend battery life. Through high-precision monitoring and complex algorithms, the BMS achieves precise control of the battery state and interacts with the vehicle controller or charger via the CAN bus, ensuring the efficient, reliable, and safe operation of electric vehicles. Furthermore, the BMS also has a balancing function, which reduces voltage differences between battery cells and extends the overall lifespan of the battery pack by finely adjusting the charging and discharging of each battery cell.

[0003] Chinese patent CN107919505A discloses a battery management device for new energy vehicles. This patent includes a cover and a housing, connected by a raised strip. The cover has a warning light and a charging / discharging interface for safety warnings and charging / discharging. The housing has a battery casing slot and a safety board mounting area. A BMS safety board is installed in the mounting area, and the BMS safety board is connected to the warning light and charging / discharging interface for control. It also includes contact points and tabs to perform electrical detection on the battery, such as voltage, current, and internal resistance. Simultaneously, an atmosphere detection device on the battery casing detects gases such as HF in the air to determine if the battery is leaking or damaged. A temperature sensing area in the center of the battery casing detects the battery temperature. Furthermore, a heat dissipation mesh and mounting groove on one side of the housing allow for the connection of an external radiator or heating equipment, ensuring the battery operating temperature remains within the optimal range and preventing safety hazards caused by low temperatures affecting battery charging / discharging or overheating.

[0004] In existing technologies, new energy batteries require pre-inspection before being put into use, and a key component of this pre-inspection is charge-discharge testing. Temperature changes during testing are crucial data, as they directly impact the battery's safety performance in subsequent use. Current technologies require disassembling the entire battery pack for temperature monitoring, which not only damages the battery structure but also increases the complexity of measurements. Therefore, improvements are needed. Utility Model Content

[0016] A further technical solution involves providing holes on both sides of the top cover, inserting the guide rod into the holes, and providing a filling groove on the side of the blade battery, with a sponge pad inside the filling groove.

[0017] Compared with the prior art, this utility model provides a battery management device for new energy vehicles, which has the following beneficial effects:

A handle 9 is located on one side of the upper magnetic head 8.

[0027] The aforementioned new energy vehicle battery management device has an upper magnetic head 8 and a lower magnetic head 18 made of magnetic material that are attracted to each other on both sides of the top cover 13.

[0028] In the aforementioned new energy vehicle battery management device, the temperature sensor 6 is provided with an anti-friction pad at the part that contacts the battery cell to prevent the temperature sensor 6 from wearing out during sliding.

[0035] Working principle:

[0036] In the actual design process, this utility model addresses the following shortcomings in existing technologies: "In existing technologies, new energy batteries require pre-inspection before being put into use, and an important aspect of this pre-inspection is the charge-discharge test. Temperature change during the test is crucial data, as it relates to the battery's safety performance in subsequent use. Existing technologies require disassembling the entire battery pack during temperature monitoring and management, which not only damages the battery structure but also increases the complexity of the measurement. Therefore, improvements are needed." This invention specifically proposes battery component 2, lead assembly 3, and temperature management component 4.

[0037] Battery Component 2:

[0038] Battery assembly 2 is the location where the battery pack of a new energy vehicle is placed. It includes stacked blade batteries 5, which are connected to each other to form a battery layer 12.
