Battery (Rechargeable) | Application

A battery is something that stores electrical energy. There are two types of batteries: rechargeable batteries and non-rechargeable batteries.

Rechargeable batteries include lead-acid, nickel-metal hydride, lithium-ion, and all-solid-state batteries. Most batteries store charge through electrochemical reactions. Because they store a significant amount of chemical energy, misuse such as overcharging, overdischarging, short-circuiting, or physical damage can lead to hazardous situations like ignition or explosion.

Matsusada Precision manufactures and sells charge/discharge power supplies (battery cycle testers) that test the quality of batteries by repeatedly charging and discharging them, as well as power supplies and electronic loads used in the battery manufacturing process.

Battery Abbreviations:

SOC: State of Charge, an indicator of the battery's remaining capacity. It is expressed as a percentage (%).
SOH: State of Health, an indicator of battery degradation. It represents the ratio of the battery's current full-charge capacity to its initial rated capacity, typically expressed as a percentage. A new battery is defined as having 100% SOH.
C-rate: A measure of the rate at which a battery is charged or discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour.
LIB: Lithium-ion battery
Ni-MH: Nickel-metal hydride battery
BMS: Battery Management System, an electronic system that manages a rechargeable battery pack by monitoring its state, calculating secondary data, reporting that data, protecting the battery, and balancing it.
BMU/BMC: Battery Management Unit/Controller. This is often the master controller within a BMS, responsible for overall battery pack management, communication with other systems, and implementing safety protocols.
CMU/CMC: Cell Management Unit/Controller. This component directly monitors and manages individual battery cells, measuring parameters like voltage and temperature, and performing cell balancing.
MMC: Module Management Controller. In larger battery systems, this controller manages a group of cells arranged in a module, often reporting to a higher-level BMU/BMC.
