When charging a battery, the following guidelines should be followed: Do not charge battery if hydrometer is clear or light yellow. Characterization testing establishes the baseline performance and includes static capacity, hybrid pulse power characterization, self-discharge, cold cranking, thermal performance, and efficiency tests. Repeat the cycle from steps 4 and 5 at the desired operating conditions the number of times specified in Table 9 or a device-specific test plan. A couple of factors could go into this: You may have too much water in the batteries should be approximately ¼ inch above the plates. Do not overtighten as nut inside battery terminal could be pulled out. They must also be periodically subjected to reference discharges to determine the changes if any in their performance characteristics.
Steps 4 and 5 will be the equivalent of one Charge-Depleting Cycle. These possibly destructive tests may be used as needed to determine the response of a given electrical energy storage system design under specifically defined abuse conditions. The rest of the analysis is the same as previously discussed. Others will put the onboard charger on the little cubby area below the rear seat if they have one. Wherever possible, the Battery Size Factor will be specified by the manufacturer, based on the manufacturer's testing and best estimates of any allowances needed for system burdens and degradation over life. You just hook up the red wire the positive to the positive terminal on the first battery in the set, and then hook the black wire the negative to the negative terminal on the last battery in the set. Such low current may not be detectable on ammeters built into many chargers.
This manual does not provide acceptance criteria as a result of the testing, but rather provides results that are accurate and fair and, consequently, comparable to results from abuse tests on other similar systems. They require a minimal number of volts to begin charging. The intervals between repetitions of these reference tests are also specified in Table 9, though these may be adjusted somewhat if required for time synchronization of cells being tested under different test regimes. Most cars operate on 12V electrical systems, and you will get it right in most cases when you purchase 12V chargers for your car batteries. What does a red flashin g light mean on my battery charger? Christophersen of the Idaho National Laboratory.
This causes batteries to lose power and not last as long. If you can get one which into the health of the battery, that would be highly recommended because such a charger will also help you prolong the life of your battery. You shouldn't take an off-board charger and put it on the golfcart and use it like an on-board charger. Do not charge, test or jump-start. Batteries are commonly located in the engine bay to one side of the engine, and often have a plastic cover which will unclip, lift off, or occasionally require the removal of a couple of bolts. At the laboratory cell level, such testing has two targets: to characterize the performance of the technology as a function of temperature and to bound the likely constraints on thermal management of full-size cells or batteries. The blue wire is not installed very often.
You will need to clean it off because if it builds up it may cause the battery cables to lose contact with the battery and keep your cart from running. If you have a battery charger that has an exterior that can be unscrewed and taken off, your charger likely can be repaired. The charger can detect and maintain maximum power in the battery. Check belt tension, using belt tension gage J-23600, against the specifications given in the Chevrolet Shop Manual. Discharge the cell for its remaining residual capacity at the 10-kW discharge rate. Due to the complexity of some of the procedures and supporting analysis, future revisions including some modifications and clarifications of these procedures are expected.
The resistance measurements will be used to evaluate resistance degradation during subsequent life testing and to develop hybrid battery performance models for vehicle systems analysis. Repeat the selected test profile s at the desired operating conditions the number of times specified in Table 9 or a device-specific test plan. To check the cranking system to verify proper operation, a simple cranking test can be done as follows: a. Some batteries may be capable of higher power than this. A default and generally mandatory end-of-test condition is reached when the test profile cannot be executed within the discharge and regen voltage limits.
If testing is performed in this fashion, the device open-circuit voltage should be checked every 24 to 48-hours to verify that the state-of-charge remains in an acceptable region. I have a 48 volt Club Car, I individually charged my batteries as described above, but the charger still doesn't work, what now? When a fast charger is connected to a cold bat- tery, the current accepted by the battery will be very low at first, then in time the battery will accept a higher rate as the battery warms. If battery terminals are severely damaged, such as loose, burned, or broken, replacement of the battery is recommended Evidence of small amounts of electrolyte leakage, especially around the vent holes, does not necessarily indicate the battery is defective -- the leakage could have been caused by overcharging or tipping of the battery. Do not tighten with wrench as bolts can be driven through case. Can my golf cart battery charger be repaired? Therefore, it may not be an excellent idea to leave it working overnight or leave it unattended for a couple of hours during the day.
Current drain can be accurately checked using digital multimeter J-29125 and two alligator clip-type jumper wires as follows: a. To properly determine minimum voltage, estimate temperature battery has been exposed to for the last several hours, i. The calculation is performed as follows: 1. To alleviate this condition, the negative battery cable, should be disconnected on vehicles which are not going to be in service within a 30 day period. Multiply each of these three pulse power capability values by the Battery Size Factor and report the resulting power values for comparison with the target of 7 kW.
It should be noted that the opinions of the 25 fleets is based on operating 179 of the 220 electric vehicles 81% response rate. Allow a 1-hr rest period before and after the 100 profiles are performed to determine any change in open-circuit voltage. Cells to be tested may be included in a matrix of test variables such as temperature and stateof-charge. A composite energy line is depicted in Figure 17. If you plug your charger into the wall but not plug it into the receptacle on your golf cart, you will not see any signs of life from the charger i. This test profile is intended for once-per-day execution during calendar life testing at the target temperature and state-of-charge.
