DWY battery maintenance device

Overview:

Valve regulated lead-acid batteries, commonly known as "maintenance free" batteries, greatly reduce the tedious and complex maintenance work of open lead-acid batteries. However, their "maintenance free" advantages are precisely the shortcomings and difficulties of operation and management. The so-called 'maintenance free' only refers to maintenance that does not require adding water, acid, or changing fluids, while daily maintenance is stillCannot be omittedThe operation, testing, and maintenance methods for open lead-acid batteries are no longer applicable to valve regulated lead-acid batteries, which poses new requirements for battery testing and maintenance equipment. Valve regulated lead-acid batteries commonly use long-term float charging in use. Due to the differences in the inherent performance of each battery in the battery pack and the influence of the usage environment, after a period of time, some batteries may experience capacity reduction or failure due to overcharging, undercharging, active substance detachment, grid plate corrosion, sulfurization, etc., which seriously affects the use of the battery and endangers the operation of the DC system.

　　DWY battery maintenance device(Battery Activation Instrument) (hereinafter referred to as "Single Dimensional Instrument"), suitable for performance testing and maintenance of various batteries. It can activate and maintain individual batteries online, with three functions: charging, discharging, and activation: charging mode - online replenishment of outdated batteries to compensate for capacity loss caused by undercharging; Discharge mode - offline full capacity discharge testing of suspected outdated batteries to obtain the true battery capacity; Activation mode - by effectively charging and discharging outdated batteries caused by vulcanization, activating active substances and restoring battery capacity
