A 48V mild hybrid electric vehicle has two electric networks: a low voltage (12 V) network and a high voltage (48 V) network. Electrical energy can be produced only by the 48V e-machine, therefore we need a DCDC converter to transfer energy from the 48V system to the 12V system.

7/1/2016 · 1. Erratic shifting. One of the first symptoms of a bad or failing downshift solenoid is erratic shifting. If the downshift solenoid has any issues, it may cause the vehicle to behave erratically when downshifting. A bad or failing solenoid may cause the vehicle to experience hard or erratic shifting when slowing down or coming to a stop.
When there are corroded wires, lose or improper connections, high and low voltage/amperage are normal, and they can cause compressors to work defectively. Check for failed superheat metering. When there is a low or high charge of refrigerant due to a bad metering device, the compressor will undoubtedly start working defectively.

10/8/2019 · The battery of your car does not—all of a sudden—”die.” • If you take a cell into a state of low voltage, you can get it to a discharge • If you expose a battery to very cold or hot conditions for an extended period, you can get it genuinely into a discharged state.
8/3/2017 · 2006 and newer 3-Series E90/E91/E92/E93 chassis. 2004 and newer 5-Series E60/E61 chassis. In conclusion, you should never gamble with resetting the BMW computer after the battery change. The procedures are cost-effective and will ensure you enjoy the pleasures of a BMW car.
One common reason for the shifter not getting out of park is low battery voltage or dead battery. If your battery is dead, replace it before you proceed with other repairs. Replacing the battery on your car is very easy, and you can replace it yourself without the need of a mechanic.

Then at its final condition greater than five time constants ( 5T ) when the capacitor is said to be fully charged, t = ∞, i = 0, q = Q = CV. At infinity the charging current finally diminishes to zero and the capacitor acts like an open circuit with the supply voltage value entirely across the capacitor as Vc = Vs.
This system involves two inputs and two outputs. Four transfer functions are involved: Yl(s)/Ul(s), Y,(s)/U,(s), Y,(s)/U2(s), and Y2(s)/U2(s). (When considering input u,, we assume that input u2 is zero and vice versa.) Solution. MATLAB Program 3-5 produces four
