Problems solved by technology

[0004] However, in the current application of storage batteries, the actual capacity of the storage battery is not easy to determine. The user cannot know how much power has been charged after the battery is fully charged, how much power has been used after a period of use, and how much power is left, so it is impossible to determine the capacity of the battery. Performance; at the same time, when using batteries, many batteries are used in series. When one of them fails, the entire circuit will not work, and the reliability of the work is low. In addition, it is necessary to check all the batteries during maintenance. Determine exactly which one is broken, expensive to repair

Embodiment 1

[0031] like figure 1 , the management control system 1 is directly embedded in the battery shell 2, there are two output terminals 5 on the management control system 1, and the two output terminals 3 of the battery and the two output terminals 5 on the management control system 1 are set There is a power supply switch 4, and the two output terminals 5 on this management control system are used as the output terminals when the storage battery is used, that is, when the storage battery is connected in series with other storage batteries Just connect the two output terminals 5 on it.

[0032] like figure 2 , at one output terminal of the storage battery, the output terminal 1 negative pole (-) is connected to the sampling resistor of the detection module, the sampling resistor is connected to the A / D conversion circuit, the A / D conversion circuit is connected to the battery management control module, and the battery management control module is connected to Breaking drive modu...

Embodiment 2

[0042] like image 3 , compared with Embodiment 1, the management and control system of this embodiment is hung outside the battery case 2, and the two output terminals 3 of the battery are respectively connected to the two output terminals 5 of the management and control system 1 through wiring. The management and control system is set separately, which will be more convenient when replacing the battery. Other technical features of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0044] like Figure 4 , 5 , compared with Embodiments 1 and 2, the power supply and disconnection switch of this embodiment is only provided with one group, which is arranged at one end of the output end of the storage battery, and the positive end (+) (such as Figure 4 ) or negative terminal (-) (such as Figure 5 ), the power supply and power-off switch also uses a relay, including two static contact arms, the first static contact arm K1, the second static contact arm K3, and one moving contact arm K2, the first static contact arm K1 is connected to an output terminal of the battery (Positive terminal (+) or negative terminal (-)), the moving contact arm K2 is used as the output terminal of the storage battery equipped with the management control system, connected to the power consumption circuit, the second static contact arm K3 and the other output terminal of the storage battery terminal (negative terminal (-) or positive terminal (+)). The moving contact arm K2 is co...

Abstract

The invention discloses a management and control system for a storage battery, which is arranged between two electrodes of a positive electrode and a negative electrode of the storage battery and two ends of an external load. Electric quantity and voltage of the storage battery are detected through a detection module, then the storage battery is subjected to charge and supply management by a battery management and control module according to a detection signal, and an alarm is given when the storage battery is invalid and the quit of the storage battery and the on and off of a total current loop are automatically or remotely controlled. The management and control system can accurately determine the rear capacity of the storage battery, thereby determining the property of the storage battery and enabling an electricity-consuming circuit to stably and reliably operate.

Description

technical field [0001] The invention relates to a storage battery, in particular to a storage battery electric energy management and control system. Background technique [0002] With the rapid development of modernization, the growth of energy demand and energy shortage are very prominent, especially the large amount of low-efficiency consumption of energy has brought serious impact on environmental pollution. [0003] The storage battery is the role of storing electric energy, and people have high expectations for the safe and reliable continuous operation of the battery. For example, electric vehicles with high power requirements, electric cruise ships, elevator backup power supplies in high-rise buildings, batteries in energy storage power supplies in solar photovoltaic power generation equipment, and backup power supplies in medical emergencies are all inseparable from batteries. [0004] However, in the current application of storage batteries, the actual capacity of ...
