Embodiment 1

[0021] figure 1 It is a structural block diagram of a battery charging management system for an elevator system provided in Embodiment 1 of the present invention. The management system 10 may include a power failure emergency device 20 , a battery charging management board 30 and a battery 40 .

[0022] Wherein, the power failure emergency device 20 is connected with the mains power supply, and is also electrically connected with the elevator system, and is used for emergency power supply for the elevator system when the mains power failure occurs. The power failure emergency device 20 also includes a charger 201. The management board 30 is electrically connected, and the battery charging management board 30 is electrically connected to the battery 40. The power failure emergency device 20 charges the battery 40 to the first capacity of the battery through the battery charging management board 30. The first capacity is based on the idle time of the elevator system on the day. ...

Embodiment 2

[0038] The following is a detailed description of the charging method of the system based on the management system for charging the elevator system battery provided in Embodiment 1. figure 2 A flow chart of steps for a method for charging an elevator system battery provided in Embodiment 2 of the present invention, specifically includes the following steps:

[0039] Step 101, obtaining the idle power of the elevator system and the busy power of the day;

[0040] In the embodiment of the present invention, the idle hour power of the day and the busy hour power of the day can be obtained. Specifically, the idle hour power of the day and the busy hour power of the day can be determined by the technician according to the design parameters of the elevator system and the actual operating conditions. Pre-set in the elevator system.

[0041] Preferably, in order to update the idle power of the day and the busy power of the day along with the different operating states of the elevato...

Abstract

The invention discloses a management system for charging of an elevator system battery, a method and a storage medium. The management system comprises a power supply storage emergency device, a battery charging management board and a battery. The power supply stoppage emergency device charges the battery through the battery charging management board to the first capacity of the battery. The firstcapacity is obtained based on a current-day idle time power and a current-day busy time power of the elevator system. The battery charging management board further comprises a coulometer which is usedfor detecting the residual capacity of the battery. The power supply stoppage emergency device is further used for charging the battery to the first capacity when the residual capacity is lower thanor equal with a second capacity of the battery, thereby always keeping charging-and-discharging of the battery in a non-full and multiple-charging-and-discharging state. The charging mode facilitatesprolonging of service life of the battery and realizes short supplementary charging time at each time. The battery is in a dormant standby state except for emergency power supply time and charging time, thereby prolonging service life of the battery.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of elevator system battery charging management, and in particular, to a management system, method and storage medium for elevator system battery charging. Background technique [0002] At present, most of the emergency power supply batteries of elevator systems on the market use a combination of constant current charging and constant voltage charging. [0003] During the charging process, the battery voltage is generally used as the method for judging the battery capacity. In order to ensure that the battery is fully charged, the set charging limit voltage is too high. When the difference between the limit voltage and the supplementary charging return pressure difference, the battery capacity is considered to have dropped, and the battery will be supplemented with charging. [0004] However, due to the polarization of the battery itself, the battery voltage will automatically drop ...
