Lithium Ion Battery over Lead Acid battery

 Lithium Ion Battery


A lithium-ion battery is a power storage product in which lithium-ions move through an electrolyte from the negative electrode to the positive electrode during battery discharge and from the positive electrode to the negative electrode during charging. The electrochemically active materials in lithium-ion batteries are typically a lithium metal oxide for the cathode and a lithiated carbon for the anode. The electrolytes can be liquid, gel, polymer or ceramic. For liquid electrolytes, a thin micro-porous film provides electrical separation between the cathode and anode.

Lithium ion battery testing

These batteries are more expensive than Lead acid battery but their lifetime per kWh is much lower when compared to lead acid batteries. The world is switching to Lithium ion batteries due to many advantages of it over lead acid batteries

  1. More energy efficient
  2. Less heavier
  3. Higher density
  4. Longer life cycle
  5. Environment friendly
  6. No maintenance
  7. Space efficient
  8. No leakage

Due to above said advantages, Lithium ion batteries become more dominant rechargeable battery.  As per IEC 62133/ IS 16046 Cells and batteries shall be so designed and constructed that they are safe under conditions of both intended use and reasonably foreseeable misuse.

Many of the tests described are very similar to those described in UL and IEEE Standards. However, a few tests specified by IEC are unique like “free fall” test which requires multiple drops of a cell or battery on a concrete floor, an overcharge test for cells that requires protection from high-voltage overcharging.

List of test is as below…….

  1. Short circuit test
  2. Abnormal charging test
  3. Forced discharge test
  4. Crush test
  5. Shock test
  6. Vibration test
  7. Heating test
  8. Temperature cycling test
  9. Low pressure test
  10. Continues low-Rate Charging
  11. Molded case stress at high ambient temperature
  12. Free fall

Vented Lead Acid Batteries: –

These vented lead acid batteries are also known as flooded or sealable or wet cell batteries. These batteries have terminals- negative terminal and positive terminal on their top or sides along with vent caps on their tops.

Scope: –

This segment of IEC standard is related to lead- acid cells and batteries those are particularly workable in fixed locations, which means that these batteries cannot be moved from one place to another. These batteries are permanently connected to the load and the d.c. power supply.

The designing of the cells and batteries shall be in such a way that they are able to withstand all the mechanical stresses during hauling, packing, handling etc.

Many other tests that comes under this standard are:-

Cl. No.

Test Name


Capacity (240 h, 120h , 48h, 10 h, 8 h, 3 h, 1 h, 0,5 h)


Suitability for floating battery operation


Endurance in cycles


Endurance in overcharge


Charge retention


Short-circuit current and internal resistance


Tests like endurance test are typically done so as ensure that the stationary cells and batteries are able to hold on against the load and be able to endure it for a long period of time. So, basically in endurance test charging and discharging cycles are done on the battery

Capacity test is done to ensure whatsoever is claimed by the manufacturer is available or not.

The other test like charge retention test helps us to see the strength of the charge present in battery if we put it in idle condition.

Some of the measuring instruments that are used while performing the other tests are voltmeter, ammeter, thermometer, hydrometers etc.

Why IEC 60601-1?

The basic scope of IEC 60601-1 is safety of patient, user and the equipment. Before launch of the Medical equipment in the market , It must be be tested as per the safety standard. All the accessories used with the equipment must be tested as per Particular standard  IEC 60601-2-X series. It is also a mandatory standard for CE, UL and CSA marking.

medical devices - IEC 60601 testing

Classification of Electro medical equipment:

There are 3 main classifications for Medical Equipment to indicate protection against Electric Shock

  1. Class 1 equipment relies on a protective earth.
  2. Class 2 equipment relies on double layers of insulation.
  3. Class 3 equipment is internally powered below the Safety Extra Low (SELV) level of 50 Vac

Why IEC 60601-1 is Important?

It ensure the safety of operator, patient and equipment itself. Below are some of the risks associated with such equipment.

  • Extravagant currents result in an electrical shock to the user or patient, to overcome this  hazard, safety standards are introduced .
  • Exceptionally high currents passing through the body cause tissue heating.Cutting, Coagulation and Physiotherapy Ultrasound are controlled uses of this effect.
  • High-frequency surgical equipment may burn the operator/ patient.
  • Due to abnormal working of incubation,high frequency surgical equipment increase in temperature of Medical Equipment.
  • An increase of respiratory via pressure caused by an abnormal working of ventilators.

Requirements of Electro medical equipment

  • Robustness of the enclosure- It must be strong enough to be used normally without any mechanical damage.
  • Earthing: It must be earthed properly so that there is no Leakage of current and must be electrical shock proof. Protective Earthing (PE) is a usual way to reduce electrical hazards by making a low resistance path in the case of a fault. Double insulated equipment does not require a safety earth because no mains parts are accessible.
  • Single Fault Condition: It must work safe in normal condition and also remain safe during single fault condition .

What is IEC 60601-1?

Standards play a paramount role in product design and development. IEC 60601-1 is a series of technical standards for the safety and effectiveness of medical electrical equipment. The force of this standard is to require two level of protection to guard the patient and operator from any injury. It is recognized worldwide. This standard is of four parts:

  1. Base standard: General requirements for basic safety and essential performance. IEC 60601-1
  2. Collateral standards: Generally numbered as IEC 60601-1-) for example IEC 60601-1-11 General requirement for basic safety and essential performance collateral standard requirement for medical electrical equipment and medical electrical system used in the home health care environment.
  3. Particulate standards: They are numbered as IEC 60601-2-) for example IEC 60601-2-52  particular requirement for the basic safety and essential performance of medical beds.
  4. Performance standards: Generally numbered as IEC 60601-3- Essential performance requirement for transcutaneous oxygen and carbon dioxide partial pressure monitoring equipment.
