What are primary batteries and secondary batteries?

Primary batteries are ordinary dry batteries that can only be used once, and secondary batteries are also called rechargeable batteries. The power battery (or traction battery) in the secondary battery is the main power source for electric vehicles.

What is the capacity of a battery?

The capacity of a battery refers to the electrical energy that can be released by the active substances in the battery when participating in the electrochemical reaction. That is, the amount of charge that the battery can hold after charging. The unit is “ampere-hour” (Ah). If a battery is discharged at a current of 1 ampere (A) for 1 hour, the capacity obtained is 1 ampere-hour (Ah). Assuming an average current of 4A, when discharged at the termination voltage of the battery, and the discharge time is maintained for 3 hours, the capacity of the battery is 12Ah (the discharge efficiency is not calculated here).

What is the design capacity of a battery?

The capacity of a battery calculated from electrochemical theory based on the amount of active material contained in the battery is called the design capacity.

What is the charge acceptance of a battery?

The amount of charge received by the battery per unit time under the specified charging voltage and current conditions.

What is battery internal resistance?

It refers to the resistance that the current encounters when flowing through the battery when the battery is working. It consists of two parts: ohmic internal resistance and polarization internal resistance. A large internal resistance of the battery will lead to a lower discharge voltage and a shorter discharge time. The size of the internal resistance is mainly affected by factors such as the battery material, manufacturing process, and battery structure. It is an important parameter for measuring battery performance.

How do rechargeable batteries achieve their energy conversion?

Each battery has the ability of electrochemical conversion, that is, the stored chemical energy is directly converted into electrical energy. In the case of secondary batteries (also called storage batteries) (another term is also called rechargeable portable batteries), during the discharge process, chemical energy is converted into electrical energy; and during the charging process, electrical energy is converted back into chemical energy. This process can be charged and discharged more than 500 times, depending on the electrochemical system.

What is the rated capacity of a battery?

The rated capacity of a battery refers to the minimum amount of electricity that should be discharged under certain discharge conditions, which is stipulated or guaranteed when the battery is designed and manufactured. The battery capacity indicated by the manufacturer refers to the amount of electricity that the battery should provide when it is discharged to the termination voltage at a rate of 10h at an ambient temperature of 25°C. It is expressed as C10 and the unit is Ah (ampere*hour).

What is the self-discharge rate of a battery?

After a battery is charged, the phenomenon of its capacity decreasing during storage is called self-discharge, also known as charge retention capacity, which refers to the ability of the battery to retain the amount of electricity stored in the battery under certain conditions when the battery is in an open circuit state. The percentage of the battery’s self-discharge to the total capacity measured over a certain period of time is called the “self-discharge rate”.

What is the actual capacity of a battery?

The actual capacity of a battery refers to the actual amount of electricity discharged by the battery under certain discharge conditions, which is mainly affected by the discharge rate and temperature (so strictly speaking, the battery capacity should indicate the charging and discharging conditions).

What is the self-discharge rate of a battery?

What are the harms of battery heating?

Whether in use or charging, the battery is allowed to have a small amount of heat, but abnormal heat is not allowed. Abnormal heat is obvious, and you can feel it by touching the battery shell. Heat is very harmful to the battery. Heat will first evaporate the water in the electrolyte and gradually dry it up, then reduce the charging efficiency, deform the plates, increase the internal resistance, accelerate the oxidation of mechanical parts, burn the plates or separators, and finally manifest as reduced battery capacity and shortened life.

Can batteries with different capacities, performances or manufacturers be connected together for use?

Can not.
