ACR: Alternative Current Resistance. aka, Impedance.

Battery impedance is a combination of internal resistance and reactance where internal resistance + reactance, or (L+ C), equals impedance when using an AC stimulus. The internal resistance of a battery is made up of two components: electrical, or ohmic, resistance and ionic resistance. For battery applications, most meters use 1000Hz, ±5mA as stimulus.

CAN: Controller Area Network. A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but is also used in many other contexts.

Neware battery tester series EVT 7000 features CAN capability, supporting information parsing acquired by BMS.

DCIR: Direct Current Internal Resistance. aka DCR. DCIR of batteries is the resistance of current flowing through the battery, with the standard unit of measurement called the ohm.The value of DCIR is not fixed, and varies depending on multiple factors, such as battery materials, electrolyte concentration, temperature, and depth of discharge.

Neware battery tester series BTS 4000, BTS 8000, BTS 9000 support DCIR tests.
