The main factor determining the driving mileage of the electric vehicle is a power supply battery. Different specifications of power supply batteries can be selected for different vehicle types so as to meet driving requirements.
A power supply battery for an electric automobile is generally a battery pack composed of a plurality of cell modules, that is, a plurality of cell modules are stacked in the same box, and then the cell modules are connected. The core cell module generally configures a corresponding number of cells according to the voltage to be output, and then connects all the cells to output the voltage. And the output of the voltage of the battery module needs to be wired with the high voltage box. The high-voltage box of the battery pack plays a vital role in the new energy automobile, and the roles of the high-voltage box of the battery pack mainly appear in the following aspects:
1. And the high-voltage distribution box receives the high-voltage direct current from the battery pack and distributes the electric energy to each high-voltage electric equipment, such as a motor, an air-conditioning compressor and the like according to the control instruction of the vehicle. Meanwhile, when needed, the electric energy generated by the equipment can be collected again and returned to the battery pack, so that the recycling and distribution of the electric energy are realized.
2. And the high-voltage distribution box precisely controls and protects the electric energy through a plurality of integrated high-voltage relays, fuses and other devices. For example, when an abnormality (such as overload, short circuit, etc.) of the circuit is detected, it can cut off the current in time, preventing the fault from expanding, and protecting the circuit and the electric equipment from damage.
3. The high-voltage distribution box has the functions of current and voltage collection, can monitor the high-voltage connection state and the insulation state in real time, and ensures the safety of the vehicle in the running process. Once an abnormal condition such as overcurrent, overvoltage, overtemperature and the like is detected, the high-voltage is rapidly cut off, and the damage to the vehicle and passengers is prevented.
4. Overcurrent, overvoltage and overtemperature protection, namely the overcurrent, overvoltage, overtemperature and other protection functions are built in the high-voltage distribution box, so that the high voltage can be cut off in time when abnormal conditions occur, the fault is prevented from being expanded, and the safety of vehicles and passengers is ensured.
5. The high-voltage distribution box also has the CAN communication function, and CAN exchange real-time data with other systems of the vehicle, thereby realizing intelligent management. This enables the vehicle to more precisely control the use and distribution of electric energy, improves energy utilization efficiency, and improves the overall performance and safety of the vehicle.
6. And the high-voltage distribution box can record and store fault information, thereby providing important basis for fault diagnosis and maintenance of the vehicle. This helps maintenance personnel to quickly locate the problem, improves maintenance efficiency, and reduces maintenance costs.
In summary, the battery pack high-voltage box plays roles of electric energy management, high-voltage safety management, intelligent management and other various functions in the new energy automobile, and the performance and the safety of the battery pack high-voltage box are directly related to the overall performance of the automobile and the safety of passengers.
