Electric stroller 12V4AH, SLA seal battery capacity detection methodEPS battery works:
Compared with the diesel engine, the EPS power supply has the advantages of non-pollution, fast switching speed, low maintenance costs, and more popular in fire-fighting power users, EPS power supply has also received more and more extensive applications.
EPS emergency power supplies use single-inverter technology, collective electrical appliances, batteries, inverters, and controllers. Inside the system, battery detection, capacity detection circuit, and fast detection function of power loss are designed. The graph gives the working principle of other major components. Take a certain intelligent emergency power supply as an example, it uses a standby mode.
Huizhong – Huizhong brand OPZV tube colloidal battery main components: Polar material 1 # Electrolysis lead, separator is an imported partition for the United States, colloid is German import colloid.
The main results are as follows: (1) When the market power is normal, market power is powered by mutual input devices, while marketing power detection and battery charging management, and then powered by the battery pack. Here, the charger is a low-power DC power supply, simply providing a charging current equivalent to the battery pack capacity (AH) 10% to the battery pack, and does not have the ability to supply power to the inverter. At this time, the power supply system consisting of the EPS AC bypass switch and the switch provides power to users of various emergency loads. At the same time, under the control of the EPS logic control board, the inverter stops working in automatic shutdown state. In this case, the load power used by the user is from the grid. Therefore, the EPS emergency power supply is often referred to as a sleep state, which can effectively achieve the energy saving effect.
Xiahua batteries include: tubular battery, colloidal battery, sealed battery, maintenance-free battery, OPZV tubular colloidal battery, OPZS battery, deep circulation battery
(2) When the market power is interrupted or the market voltage exceeds the limit (¡À 15% or ¡À 20% rated input voltage), the mutual switching device will immediately switch to the inverter power support supported by the battery pack, the user load The power used is an AC power source converted through the EPS inverter instead of a market power supply.

(3) When the market voltage returns to normal operation, the EPS control center issues a signal, automatically shuts off the inverter, and also switches from the inverter power supply from the inverter power source through its switching switch. Thereafter, the EPS also charges the battery pack through the charger while providing market power to the load through the AC bypass power channel.
