Now, let's delve into how a BMS enhances the performance of lithium-ion batteries. The battery management system (BMS) maintains continuous surveillance of the battery's status, encompassing critical parameters such as voltage, current, temperature, and state of charge (SOC).
BMS is an essential device that connects the battery and charger of EVs . To boost battery performance and energy efficiency, BMS is controlled by critical aspects such as voltage, state of health (SOH), current, temperature, and state of charge (SOC), of a battery .
These decisions hold substantial sway over the battery's overall performance and lifespan. Without the vigilant oversight of a BMS, a lithium-ion battery might be susceptible to overcharging or excessive discharging, both of which can markedly curtail its longevity and even result in battery failure.
Use a BMS with an alternator port with built-in current limiting, such as the Smart BMS CL 12/100 or the Smart BMS 12/200. For more information on charging lithium batteries with an alternator, see the Alternator lithium charging blog and video. Alternator charging 3.5. Battery monitoring
The battery communicates these alarms to the BMS via its BMS cables. The BMS receives an alarm signal from a battery cell If the system contains multiple batteries, all battery BMS cables are connected in series (daisy chained). The first and the last BMS cable is connected to the BMS.
In the event of high cell voltage or low/high battery temperature, the Smart BMS 12/200 will send a “charge disconnect” signal to turn the charger (s) off. The alternator port controls and current limits the alternator. For more information see the Smart BMS 12/200 product page.
