Noco Battery Isolator Manual Arts
Once the vehicle is started, the unit automatically electrically disconnects from the vehicle's battery. Click
Various attempts to eliminate these problems have been made in the prior art U S.. Problems with the prior art arose when either the jumper terminals or clamps of the cables were inadvertently brought into contact with each other while the other ends were connected to a charged battery, or when the positive and negative terminals were connected to the opposite polarity terminals in the vehicle to be jumped, thereby causing a short circuit resulting in sparking and potential damage to batteries and/or bodily injury. 2
Therefore, the positive and negative terminals of the two batteries are correctly connected based on the detected result of the polarity detecting unit.. After the polarity of each clip is sensed by the polarity detecting unit, the switching unit generates a proper connection between the two batteries.. U S Pat No 5,189,359 issued Feb 23, 1993, discloses a jumper cable device having two bridge rectifiers for developing a reference voltage, a four-input decoder for determining which terminals are to be connected based on a comparison of the voltage at each of the four terminals to the reference voltage, and a pair of relays for effecting the correct connection depending on the determination of the decoder. 3
The control circuit causes power current to flow through the solenoid assembly only if the points of contact of booster cable clamp connections have been properly made.. The REDARC Smart Start SBI12 100A is a 12V DC 100A microprocessor-controlled, dual battery isolator designed to protect the start battery from excessive discharge while allowing the auxiliary battery to supply charge to non-essential loads.. Pat No 6,212,054 issued Apr 3, 2001, discloses a battery booster pack that is polarity sensitive and can detect proper and improper connections before providing a path for electric current flow. e828bfe731 HERE
The adaptive booster cable includes a polarity detecting unit connected to each clip, a switching unit and a current detecting unit both provided between the two pairs of clips.. No connection will be made unless only one terminal of each battery has a higher voltage than the reference voltage, indicating positive terminals, and one has a lower voltage than the reference voltage, indicating negative terminals, and that, therefore, the two high voltage terminals may be connected and the two lower voltage terminals may be connected.. The system includes an internal battery to provide the power to the battery of the vehicle to be jump started.. The present invention relates generally to apparatus for jump-starting a vehicle having a depleted or discharged battery. HERE
