If the batteries remain in a "float stage" for a seven-day period, the IQ4 will switch the DLS charger into a pre-programmed Maintenance Stage. The IQ4's float stage prevents boiling and bulging of the battery caused when the battery is exposed to higher charging voltages for too long. This reduced voltage maintains the full charge while minimizing 'gassing' of the battery. This mode will continue for up to 480 minutes (8 hours) to ensure that the battery receives a complete charge.ĭuring the Float Stage, the IQ4 reduces the DLS charge voltage. This increased charging period reduces the overall charging time of the battery.Īfter the Bulk Stage, the IQ4 then moves to the Absorption Stage. The Bulk Stage of the IQ4 allows the batteries to be charged from the full rated output of the charger. IQ4 Charge StatesThe IQ4 progresses through the following stages while charging your batteries: Bulk Charge Note: External IOTA IQ Smart Charge Controllers are not compatible with DLS units with internal IQ charge controllers. Your DLS will now provide an automatic and trouble free charging profile to your batteries! Once plugged in, the IQ Smart Charge circuitry is automatically engaged and your IQ module will activate. InstallationThe IQ Smart Charge Controller easily plugs into the Dual Voltage Jack of your IOTA DLS Battery Charger. The IQ4 is an excellent way to maintain your stored flooded lead acid batteries, such as in an RV that is parked for extended periods of time. IOTA's traditional IQ4 Smart Charge Controller delivers 4 basic charging functions: BULK, ABSORPTION, and FLOAT, and a seven-day MAINTENANCE cycle.

If you have convenient access to workplace charging, that may also impact how often you choose to charge your electric BMW overnight. Keep in mind that how often and how long you should charge your electric BMW depends in part on what kind of home charging option you have and your daily driving needs. Use DC and high-power DC chargers as often as you need, in order to extend the mileage of your electric BMW in a short period of time. While it takes longer, it is less stressful on the high-voltage battery and also a more cost-efficient way to get your range topped up. When not driving your electric BMW for a longer period of time, leave the battery between 20% and 80% charged. However, it is not recommended to charge up to 100% every day – as this can harm the battery in the long run. You can charge the battery up to 100% when you have to rely on the entire driving range of your vehicle (for a longer trip), as occasional charging to 100% doesn’t harm the battery. Staying between 20% to 80% battery capacity should leave you with enough driving miles – and you can use iDrive or your My BMW App to set a target state of charge. The amount of miles you drive daily will determine how much charging you will need. Similar to your cell phone, charging up your electric BMW before a day’s use is simple.
