Whether the alternator is fitted with an internal or an external voltage
If your car has an alternator, the warning light wire connection depends on Marked either WL or IND - this is the wire you , often mounted on the bulkhead or inner wing. But first you need to knowĮxactly which type of charging system you have so that you can identify theĬars fitted with a dynamo have the warning light wire connected to a remote Or if anything we could improve, email us, we will read the comment and provide a high-quality battery knowledge tutorial.To make this check you will need to find the warning light wire in theĮngine bay where it connects to the charging system.

#CAR BATTERY INDICATOR MEANING FREE#
If you have any questions about this topic ( What is the SOC ( State of Charge )? ) or have any battery-related things you want to know, please feel free to contact us by email at specialize in drone smart batteries, industrial batteries, shaped batteries, high discharge rate batteries, high voltage batteries, semi solid batteries, etc. Grepow‘s Battery Monday Channel is about battery knowledge and battery tip. Therefore, the SOC indicator on a BMS is vital for user convenience, as well as the efficiency, safety and life of the battery. In addition, SOC estimation can be used to regulate battery life degradation, explosions or fires due to battery over-discharge and overcharge, as well as aging and permanent damage to the battery cell structure. These parameters are also affected by a variety of uncertainties such as battery aging, temperature changes and usage status.Īccurate SOC estimations reflect important information, such as battery performance, remaining battery life, etc., which ultimately leads to efficient management and utilization of battery power and energy. The SOC of a battery is a combination of voltage, charge/discharge current and internal resistance parameters to estimate its size. Most SOC estimations require precise data measurements, whether it is the chemistry of the cell (type of electrolyte), its operating conditions, or the variables of the cell ( voltage, current), etc., thus being suitable only in the laboratory and not in real applications. The absolute SOC of a new fully charged battery is 100% while an aged battery, even if fully charged, cannot reach 100% in different charge and discharge situations. There is also what’s called an absolute charge state, which is a reference value calculated from the fixed capacity value when the cell is manufactured. When the SOC is at 100, it means the battery is completely full. The SOC is calculated as a percentage: when it’s at 0, it means the battery is completely discharged. It represents the ratio of the current capacity of the battery to its nominal capacity after a period of use or long-term shelving, which also indicates the maximum amount of power that can be stored in the battery. The SOC is the measurement of the amount of charge remaining on a battery. As shown in the picture here, this is the SOC power indicator seen on a smart battery with a BMS. The BMS monitors the battery based on the SOC and prevents battery overcharge and overdischarge, and extends the service life of the battery. The SOC, in particular, is important because of its role with the BMS. When we check on the status of a Li-ion battery, we will often look at the battery temperature, the SOC, SOH, SOS, SOF and SOE.
