Embodiment Construction

[0031] Four lead-acid batteries with a capacity of 10AH are used, and the power is 0%, 50%, 0%, and 50% respectively. Click the start charging button to charge it. In the case of no balance and no protection, the charging result is as follows: Figure 4 shown. It can be seen from the figure that No. 1 and No. 3 batteries are fully charged before No. 2 and No. 4 batteries are fully charged, and continue to charge, which will cause overcharging of No. 2 and No. 4 batteries, which will lead to the failure of the entire battery pack. Turn on the function button of the protection board. After charging the four batteries, in the case of no balance and protection, the Figure 5 It can be seen that when the No. 2 and No. 4 batteries are fully charged, the other two batteries are no longer charged, thereby solving the above-mentioned problem of overcharging the batteries before the protection board is added. Enable the balanced version function, that is, when there is balance and pro...

Abstract

The invention discloses simulation software for equalization and protection of batteries which are connected in series. Four storage batteries of 12V 10-20Ah are used in an electric vehicle or a communication station at present, the storage batteries are connected in series, the service life of the storage batteries is only half a year or up to two years, therefore, the short service life and high cost of the storage batteries become the greatest problems. Moreover, the batteries are damaged in a slow time-consuming process of years and months, and therefore, the process is difficult to monitor. The invention relates to the simulation software for equalization and protection of batteries which are connected in series. According to the simulation software, the condition of each battery in the charge / discharge process of the batteries can be visually displayed in relatively short time; how the batteries are damaged in the charge / discharge process of the batteries which are connected in series can be simulated under the conditions that the balance function and protection function exist or do not exist; and the theoretical basis is provided for use of the batteries which are connected in series. The simulation software for equalization and protection of batteries which are connected in series is provided by using a graphic program language as a platform for visually displaying the monitoring data of a battery management system. The simulation software comprises a verification code module, a protection board module and an equalizing charge module.

Description

technical field [0001] At present, most electric vehicles and communication base stations use four 12V10~20Ah batteries in series, and the service life is as long as 2 years or as little as half a year. The short service life of batteries and high cost have become the biggest problems. And battery pack damage is a slow process that takes years and months, making it difficult to monitor. The patent of the present invention relates to a simulation software for equalizing protection of a series battery pack, which can visually present the status of each battery in the charging and discharging process of the series battery pack in a relatively short period of time, and simulate whether the series battery pack has a balancing function during the charging and discharging process , How is it damaged when there is no protection function, and provides a theoretical basis for the use of series battery packs. Background technique [0002] As an economical and practical, energy-saving ...
