Embodiment 1

[0027] The battery management module 6 is connected to a display device on the battery cover of each single storage battery, and the display device is installed on the cover sheet 8. The display device can display the voltage, current, and voltage of the single storage battery. For parameters such as temperature, capacity, remaining battery capacity SOC, and battery health status SOH, each single battery is equipped with a display device, which is convenient for finding the problematic single battery in time when there is a problem with the battery.

Embodiment 2

[0029] By enclosing a battery pack with a shell, the shell is provided with holes, and the battery management module 6 on each single storage battery is connected to the display device outside the shell through the hole on the shell, and the display device is installed on the on the shell. The parameter status of all single storage batteries in the storage battery pack casing is displayed on the display device, so that the staff can clearly see the conditions of all the single storage batteries in the storage battery pack, which is convenient for comparison and judgment, and saves the use of the display device.

[0030] In addition, the display device can be a vehicle display, a handheld computer display, a portable computer or a mobile phone, etc., and can be installed anywhere that is convenient for personnel monitoring. Of course, the connection between the display device and the battery management module can also be realized wirelessly.

Abstract

The invention discloses a wireless intelligent battery. The wireless intelligent battery comprises a storage battery pack; the storage battery pack is composed of a plurality of single storage batteries which are in series connection; battery terminals of the single storage batteries are respectively connected with sensors used for detecting battery parameters; the sensors are connected with battery management modules; data collected by the sensors are transmitted to the battery management modules; the battery management modules are connected with wireless communication modules; each single storage battery is provided with a battery end cover; a mounting groove is formed in each battery end cover; the battery management modules and the wireless communication modules which are connected with one another are arranged in the mounting grooves; the wireless communication module of each single storage battery communicates with each other; Internet communication ports are also formed in the single storage batteries. According to the invention, intercomparison on charge-discharge conditions of each single storage battery can be achieved to prevent floating charge of the single storage batteries; data parameter values of each single storage battery can be transmitted to a server through the Internet, so that unified monitoring of technical personnel is convenient.

Description

technical field [0001] The invention relates to an intelligent battery capable of realizing wireless communication between single storage batteries and real-time monitoring and adjustment of charging and discharging process. Background technique [0002] Usually the terminal voltage of a single-cell battery in a lead-acid battery pack is about 2 volts. If a higher battery voltage is required, such as the commonly used 6 volts, 8 volts, 12 volts, etc., the multi-cell single-cell battery connected in series to meet power requirements. However, there are two problems due to the differences between the single-cell batteries. One is that a certain single-cell battery will be overcharged during charging, and the other is that a certain single-cell battery will be over-discharged during discharge. Both of the above problems will cause Affect the balance of the entire battery pack, and there are potential safety hazards. For this reason, some technicians have also designed a batte...
