Cold Cranking Amps (CCA) | How to Choose Your Battery | Autobatteries.com | Clarios

https://www.autobatteries.com/en-us/how-to-choose-your-car-battery-replacement/battery-cold-cranking-amps-cca

Saved by uncleflo on December 17th, 2019.

CCA is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. Generally speaking, it is easier to start an engine in a warm environment than in a cold one. The rating refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the greater the starting power of the battery. If you live in a cold climate, the CCA rating is a more important consideration than it is if you live in a warm one. Battery starting power deteriorates as the battery ages, so a battery with higher starting power should give you more confidence over time. Replacement batteries should equal or exceed the OE battery in ratings. Replacing a battery with a battery that has a lower CCA than the original equipment may result in poor performance.

This compact (0.45″×0.6″) U1V11F3 switching step-up (or boost) voltage regulator efficiently generates 3.3 V from input voltages as low as 0.5 V. Unlike most boost regulators, the U1V11F3 offers a true shutdown option that turns off power to the load, and it automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

DIY 24v LiFePO4 Solar Battery Bank! Beginner Friendly, 2.4 kWh, Cheap, Full Tutorial! - YouTube

Safety Update: If the cells have a voltage difference of more than .2 of a volt (example: one cell is 2.7 volts, and another cell is 3.5 volts), you should not parallel connect, and instead discharge the higher voltage cell with a 25-50 watt, 1.5-2.7 ohm resistor. Just attach the leads of the resistor to the individual higher voltage cell, and wait till it is at a voltage that is closer to the other cells. When they are within .2 volts of each other, then you can connect them in parallel and allow them to equalize. Another way to do this is to charge the lower voltage cells, but 3 volt chargers are not easy to find, so I would stick to the resistor method. These resistors only cost a dollars each, and you can find them at most electronics supply stores.

A variable speed wind turbine is disclosed comprising a turbine rotor that drives an AC induction generator, a power converter that converts the generator output to fixed-frequency AC power, a generator controller, and an inverter controller. The generator controller uses field orientation to regulate either stator currents or voltages to control the torque reacted by the generator. The inverter controller regulates the output currents to supply multi-phase AC power having leading or lagging currents at an angle specified by a power factor control signal.

This instructable explains how to build your own 100 HP (peak) motor controller for use in an electric car or motorcycle conversion. It can take any voltage up to 144v, and the peak current is 500 amps. The cost of the components is a few hundred dollars, which means you can save over $1000 by putting one together yourself. At 144v, you can expect a top speed of around 75 MPH in a car.

Freeway capable EVs are more expensive than slow EVs because you need more batteries (sometimes: could use buddy pairs at lower voltage) and a high voltage controller. The same motor can often still be used, just by advancing the brushes, and maybe adding a blower to keep it cool. So, it seems to me that the best place to focus efforts to making freeway capable EVs more affordable (under $1500?), is to focus on the controller. About $1200 or so can be shaved off the cost of a new controller.

Physical electronic access control, almost always, involves driving an electromagnetic locking device of some kind. It might be a powerful magnet or a smaller solenoid within a strike. All these devices are subject to the same basic laws of physics. The electromagnet will store energy when powered and will generate a “back EMF”, or counter EMF (CEMF), when the supply is switched off.
