18 years of commitment to the global lithium electricity users to provide professional technical support and product services, its customized programs lithium-ion batteries are widely used in medical industry.

Application:  

Medical ultrasound machine, Electrocardiogram machine, Monitor, Breathing machine, Anesthesia machine, Oxygen generator, Injection pump, Medical air pump, Oximetry, Glucose meter, Heart pacemakers, etc.

The scheme is designed to meet the standards of the medical industry and the global UL, CE, FCC, PSE, KC, BSMI, UN38.3, and ROHS.

Design requirements for lithium battery for medical infusion pumps:

Medical infusion pump is a new type of medical infusion of intelligent medical products, due to the particularity of its application and the environment, the requirement of battery is also very special, such as: battery of input, output, must use the same port, so that the safety of the relevant personnel convenient operation; The battery must be approved for charge and discharge, and the power indicator must be always bright so that the patient and the relevant personnel will observe it.

Battery safety and fire protection grade must meet the special requirements of medical products.

1) lithium-ion battery model design requirements: 18650-2s4p / 10Ah / 7.4 V.

2) input and output characteristics: output and output adopt the same port, and the automatic switching function is required according to the special requirements of medical care.

Output feature: the DC line output port automatically outputs 5V / 2A properties without charge.

Input features: an adapter with 9V / 2A on the DC output line, and the battery is automatically charged.

Status feature: no output when 9V / 2A is charged, and automatically switches output 5V / 2.5 A when 9V / 2A is taken.

Item	Min.	Standard	Max.	Unit
Input Voltage	8.5	9	9.5	V
Input Current	1.8	2	2.2	A
Output Voltage	5.2	5.4	5.6	V
Output Current	0	2	2.2	A

 

3) charging and discharging instructions: a single monochrome lamp and a two-color lamp for high/medium/low three instructions.

6.4 V plus or minus 0.1 V lights red

7.3 V plus or minus 0.1 V light blue

7.9 V plus or minus 0.1 V light blue

4) discharge status: when the red light is extinguished, the discharge can be supported for about 10 to 20 minutes.

5) basic features of the protection board

Single-section overcharge protection voltage: 4.28 plus or minus 0.25 volts

Full recovery voltage: 4.10 + 0.10 V

Protection voltage for single section: 2.80 plus or minus 0.08 V

Single-stanza recovery voltage: 3.00 + + 0.10 V

Combined battery over-current protection value (10ms) : 8 ~ 12A

Combination of battery over temperature protection value (restoration) : 70 + 5 ℃

The finished battery has short circuit and anti-charge protection.

6) battery life design requirements: 300 ~ 500 times (national standards for charging discharge)

7) the design requirement of battery size design
