The customer confirms the model of the product required to be purchased = We will prepare a detailed formal quotation process based on the inquiry model, price and delivery date.
The customer orders the product after receiving the quotation and confirming that the model is correct = the person in charge of the quotation drafts a sales contract based on the model and quantity provided by the customer.
After receiving the contract review and approval, the customer will stamp and return it and remit the money to the company's account bank according to the contracted sales volume.
After our company's finance department checks the payment, the salesperson arranges the shipment and notifies the customer to track the waybill.

Battery pack capacity
The battery pack should be tested for capacity according to the discharge current and discharge end voltage specified in the table.
The battery pack should be charged and discharged three times, and the third cycle should reach the rated capacity.
Battery discharge end voltage and charge and discharge current
Battery category nominal voltage discharge end voltage rated capacity charge and discharge current
Note: (hour) rate rated capacity. (Amp hour) (hour) rate discharge current value/.
, (hour) rate rated capacity. (Amp hour) (hour) rate discharge current value/.
Accident discharge capacity
The battery pack is discharged according to the specified accident discharge current and then superimposed with the specified impulse current for sub-impact discharge. The impulse discharge time is the interval between two impulse discharges. The voltage on the DC (power) bus during the first impulse discharge shall not be lower than % of the DC nominal voltage.
Load Capacity
When the equipment is operated in a normal floating charge state and an impact load is provided, the voltage on the DC bus must not be lower than % of the DC nominal voltage.
Continuous power supply
When the AC power supply is suddenly interrupted during normal operation of the equipment, the DC bus should continuously supply power. The voltage at the moment when the DC (control) bus voltage fluctuates should not be less than % of the DC nominal voltage.
Voltage adjustment function
The voltage adjustment device in the equipment should have manual voltage adjustment function and automatic voltage adjustment function. Equipment using stepless automatic pressure regulating devices should have backup pressure regulating devices. When the backup voltage regulating device is put into operation, the DC (control) bus should be continuously powered.
The technical performance equipment of the charging device should have charging (constant current, current-limiting and constant-voltage charging) float charging and automatic conversion functions and soft-start characteristics.
The main technical parameters of the charging device should meet the requirements in the table.
Accuracy of charging device and allowable value of ripple system
Project name Category of charging device
Magnetic amplifier large-scale phase-controlled high-frequency switching power supply type
Voltage stabilization accuracy
Stable Current accuracy
Ripple coefficient
Parallel current sharing requirements for high-frequency switching power supply modules
When multiple high-frequency switching power supply modules operate in parallel, their current sharing unbalance should not be greater than %.
Voltage limiting and current limiting characteristics
The charging device operates in a steady current charging mode. When the charging voltage reaches the voltage limiting setting value, the equipment should be able to automatically limit the voltage and automatically convert to constant voltage charging operation. The charging device operates in a regulated charging mode. If the output current exceeds the set value of the current limit, the device can automatically limit the current and automatically reduce the output voltage. The output current will immediately drop below the set value.
The adjustment range of the charging current during constant current charging is % ~ % (the same applies to the rated current).
The adjustment range of charging current during constant voltage operation is ~%.
Battery pack charging voltage adjustment range
The voltage adjustment range is %~% (lead-acid battery)%~% (valve-regulated battery)%~% (cadmium-nickel battery) DC nominal voltage.
