Battery management system and management method thereof

Abstract

The invention discloses a battery management system and a management method thereof. In a battery management mode of the invention, single independent control is developed into networked intelligent control so that a disadvantage that independent control is unviewable is overcome; and a problem can be timely and accurately discovered, and the problems can be solved in a one to one mode. System software upgrading of a BMS is as simple as client system upgrading. A fault generation probability is greatly reduced. After-sale maintenance convenience and efficiency are increased, and after-sale cost is reduced. Prediction precision of a remaining mileage is increased, and a battery isolation strip can be effectively reduced, which means that a usable capacity of a battery can be increased. A workload and time of early-stage battery sample assessment can be effectively saved and reduced, and a battery number required by an experiment is decreased. A man-machine interaction function is realized through a client.

Description

technical field [0001] The invention relates to battery technology, in particular to a battery management system and management method. Background technique [0002] Battery data collection is generally divided into two types: [0003] Static state of the vehicle: generally use a dedicated chip, such as LTC6803 / 6804, to measure the voltage of the battery in a static state and the environment. Since the voltage corresponds to the SOC one by one, the voltage value is converted into a percentage of SOC and then combined with the nominal power of the battery. , to get the remaining power of each single battery. Due to the short board effect, the battery with the lowest power is taken as the overall standard; (the original data collected by the chip is correct, and the percentage of remaining power obtained is correct, but the actual battery The power is uncertain, the remaining power is an estimate,) [0004] When the vehicle is running, it is generally measured by the ampere-...

AI Technical Summary

Problems solved by technology

When the vehicle has the above problems, the algorithm should be adjusted, that is, re-download the program, which is impossible with the existing technology, unless all sold vehicles are recalled, and re-downloading the program often causes some subtleties to the car. The most important thing is that the situation of each car is different, and the developer has no way of knowing the rest of the details

Inability to solve problems one-on-one

Information cannot be communicated with the outside world, and the outside world cannot know what the internal situation is unless the PACK is disassembled
