Description
Technical Field
The utility model belongs to the technical field of battery pack maintenance, and particularly relates to a whole battery pack maintenance device.
Background
With the increasing challenges of energy crisis and environmental pollution, countries around the world are dedicated to the development of new energy vehicles. At present, the lithium ion battery has the advantages of high energy density, low self-discharge rate and the like, and is widely used as a power battery of a pure electric vehicle. In practical application, a large number of battery cells need to be connected in series and in parallel to form a group, and then the requirements of high voltage and high power of the pure electric vehicle can be met.
However, power battery packs often exhibit inconsistencies over multiple charge and discharge cycles. The inconsistency means that the voltage or State of Charge (SOC) is not exactly the same between the battery cells. In use, overcharge or overdischarge phenomena may occur, which may cause irreparable damage to the battery, seriously affecting the service life of the battery.
SUMMERY OF THE UTILITY MODEL
An embodiment of the present invention provides a battery pack maintenance device, and aims to solve the problem that after a plurality of charge and discharge cycles, an existing power battery pack is generally inconsistent, and during use, an overcharge or an overdischarge phenomenon may occur, which may cause irreparable damage to a battery, and seriously affect the service life of the battery.
The embodiment of the utility model is realized in such a way that the whole battery pack maintenance equipment comprises:
the system comprises an upper computer screen, a battery power supply device and a control device, wherein the upper computer screen is connected with the battery power supply device and is used for sending battery parameters needing to be balanced;
the battery power-supplementing balancing device is connected with the upper computer screen through the gateway board and connected with the battery pack through the wiring harness and used for regulating and controlling the battery pack.
In a further technical solution, the battery parameters include: battery type, capacity, equalization target voltage, current, and various termination conditions.
According to the further technical scheme, data sent by the upper computer screen are converted into serial port signals through serial port lines and sent to the battery power supply balancing equipment.
According to the further technical scheme, the battery power supply balancing equipment detects data from an upper computer screen through USBCAN equipment.
According to the further technical scheme, the battery electricity supplementing and balancing equipment is led into the corresponding DBC through CANOE and is used for observing data change of the battery.
According to the maintenance equipment for the whole battery pack, provided by the embodiment of the utility model, a user can set the battery type, the capacity, the balanced electric core number and the balanced mode through the upper computer screen. The battery electricity supplementing balance equipment is internally provided with protection such as overvoltage, undervoltage, overtemperature and overcurrent, and the like, so that the electricity supplementing equipment is prevented from overcharging and overdischarging the battery core. Meanwhile, the battery cell with the lowest/highest voltage of the battery pack is obtained through an internal logic algorithm, and the battery cell is charged/discharged. Because the utility model adopts a polling charge-discharge strategy, only one cell can be balanced at the same time, and the balancing time is longer than that of the similar equipment, so that the rest cells have enough time to depolarize, the time for the rest cells to reach a steady state is longer, and the battery is kept more stable.

In the drawings: an upper computer screen 1; a battery power supply balancing device 2; a wire harness 3; and a battery pack 4.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Specific implementations of the present invention are described in detail below with reference to specific embodiments.
As shown in fig. 1, a battery pack maintenance apparatus according to an embodiment of the present invention includes:
the system comprises an upper computer screen 1, wherein the upper computer screen 1 is connected with battery power supplementing equipment and is used for sending battery parameters needing to be balanced;
the battery is mended electric equalizer 2, battery is mended electric equalizer 2 and is connected with host computer screen 1 through the gateway board, battery is mended electric equalizer 2 and is connected with battery package 4 through pencil 3 for regulate and control battery package 4.
In the embodiment of the utility model, the battery parameters needing to be balanced are sent through the upper computer screen 1: the battery type, capacity, balance target voltage, current, various termination conditions and the like, and the serial port line converts the received data into a serial port signal and sends the serial port signal to the battery power supply balancing device 2. The device equalizes the inconsistent cell voltages on the battery pack 4 to a consistent target voltage through an internal algorithm. The battery electricity supplementing and balancing device 2 can also detect data through USBCAN equipment and issue and configure through the upper computer screen 1, so that the battery electricity supplementing and balancing device 2 is controlled to balance a single battery in the battery pack 4, and data changes of the battery can be observed by leading in corresponding DBC through CANOE.
The device has two modes to choose from: an average voltage equalization mode and a target voltage equalization mode.
Working mode 1: automatically to average voltage equalization. The device regularly updates the average voltage of all the current battery cells, and the average voltage is used as a target voltage for balancing. The unit cells higher than the average voltage are discharged and the unit cells lower than the average voltage are charged. The current equalized channel depends on the actual voltage difference.
The working mode 2 is as follows: automatically equalize to the set voltage. The voltage set by the upper computer is used as a target voltage for balancing, the single batteries higher than the target voltage can be discharged, and the single batteries lower than the target voltage can be charged. The current equalized channel depends on the actual voltage difference
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
