[EVDL] K BC20 96 volt charger replacement?
Hoping someone can recommend a replacement for K BC20 charger (home converted 62 MG Midget with that has suddenly stopped being able to charge fully without tripping... can only output 7 A ) or if someone has one they are selling as an upgrade? Its worked for 12 years but suddenly does not seem to be able to fully charge the battery pack(new) and i'm afraid its going to damage them.. I'm using 8 12v deep cycle (flooded lead acid) batteries and have a separate DC converter for auxillary... Any suggestions would be appreciated! thanks m. perillat -- next part -- An HTML attachment was scrubbed...

[EVDL] FW: Summary of all EV Manufacturers announcements?
Can anyone help me put together a compendium of one line summaries from every Auto manufacturer’s announcement of what and when is their EV plans? I keep seeing such announcements that XX MFR announces that YYY of their models will be ELECTRIC by ZZZ. We need to collect that in one place and keep it updated. Green Car Reports says they don’t have timetime, but if we can get such a list started, they will take the ball and run with it. I remember vaguely Mercedes and BMW have said all their models will be electric (of some form) in ??? ten years? Ford has said all of thers will be …? VW recently announced… And many more But I need a link for each one. Bob -- next part -- An HTML attachment was scrubbed...

[ref http://electric-vehicle-discussion-list.413529.n4.nabble.com/K-W-BC20-96-volt-charger-replacement-tp4688063.html ] Looking at your evalbum.com listing: http://www.evalbum.com/200.html And an old resume of yours: http://www.armory.com/~me/ I can see she is likely not afraid of doing some EV work herself. A very long time ago, Clare Bell ... https://www.google.com/search?q=electric+car+clare+bell (scientist, engineer, EV repair and builder, turned author, +more) ... found that if the tops of a PbSO4 wet cell pack being charged by a BC-20 got dirty, wet, or otherwise contaminated (as posted), that would cause leakage a current to trip the BC-20's built in gfi. So, I would plan to fully charge your pack (the best you can), unplug the charger, pull the pack disconnect (for your safety), clean the tops of your pack (the best you can using a windex-type/glass/mild alkaline cleaner), then clean off with water wet wipes any left over cleaner, ensure the tops are quite dry, take & write down/document surface voltage readings (SOC) of each 12V battery, then try charging again. I'll assume the K BC-20 has the correct resistor installed for charging a 96VDC PbSO4 wet-cell pack. Here is what the evdl has for the BC-20: http://www.evdl.org/docs/bc-20.pdf Because your pack is 96VDC, you can ignore the references to the boost transformer. IMO, the BC-20 is a 1990's vintage cheap charger: -not isolated from the AC line -had horrible power factor correction (pfc), about 50% -had a huge current spike that was very hard on plugs, outlets, cords, wiring, and AC breakers. -the built in current meter displayed an odd-ball TMS rather the more common RMS. So, to get an average current of 10A from the AC outlet (so you did not trip its breaker), the charger's TMS meter should display 7A, etc. I know chargers, I had six of them built into my S-10 blazer: http://brucedp.0catch.com/blazer/ and the Ford Escort sta. wgn (Clare tricked out for me): http://brucedp.0catch.com/escort/ I had for a short while, had a BC-20 in it. So, I have had experience with BC-20, Zivan, mm pfc-xx, and pro-series boat chargers. I would suggest that after you have cleaned the pack (state above), that you unplug your EV, use a standard 12VDC starter battery charger to top off each of your 12V batteries, let them rest for an hour, and then record their surface voltages. Lets assume Mary's eight 12VDC deep-cycle batteries are healthy enough, and now fully charged (If not, perhaps you have a battery with weak cells, and you are looking at a pack change). 12VDC deep-cycle batteries do not last as long as 6V golf/traction batteries. The latter have thicker plates= more lead. i.e. whereas you can have a pack of 6V last you 3 years, I have found a pack of 12V batteries is lucky to last 1.5 years. You really have to keep them charged properly and never-ever discharge them beyond 50%, the less the better. If you have to replace your pack, I suggest: http://www.sears.com/automotive-batteries-marine-batteries/b-1100201 select the appropriate size you currently have, either group 31, 27, or 24. I have had good cycle life with these, but the hardship is ensuring your Capitola Sears store has all eight of your fresh (same date) batteries in stock, and you will have to remove the dead ones from your EV yourself ahead of time, to take them in that same day for the dead core-credit$. Mary asked about a replacement charger. With today's production EVs, much has changed with the term charger. A simple search: https://www.google.com/search?q=electric+car+charger gives L2 EVSE, not actual chargers (L2 EVSE only provide AC power to the EV's on-board AC to DC charger). What Mary needs is an actual AC to DC PbSO4 battery charger. I found another BC-20 http://www.evtradinpost.com/item/3004 but really, that ancient charger should be pulled out and put in a museum, and replaced with a charger from this time period. Your BC-20 is likely set to draw 12A AC off a 120VAC 15A outlet, which likely only puts 6A into your 96VDC pack (the charger is only ~50% efficient, a lot of power is wasted as heat). A 12A AC draw is 1440watts. (Note: any links I provide from EV re-sellers does not mean I recommend or prefer them over others, they are just an example. The buyer should do their own research for the best deal that fits their EV needs) Delta-Q is a fine dual input voltage charger. It seems to me, the Delta-Q is solid, but more costly with less power out. https://cdn.hackaday.io/files/18376786198784/delta-q-battery-charger-manual.pdf The Zivan k & ng series chargers evolved into the series Elcon sells. I would go with a ~$600 Elcon pfc-1500 if Mary wanted a drop in charger (same power, etc.): http://www.elconchargers.com/catalog/item/7344653/7638003.htm http://www.electriccarpartscompany.com/assets/images/Lead_Acid_Ligoo-user-manual-15kw-1500w_Battery_Charger_EV_Battery%20Charger_TCCH_PFC-1500.pdf
Re: [EVDL] K BC20 96 volt charger replacement?
I have a BC20 with the full set of resistors, and a Zivan NG3 that are used, and either should work well for your needs. Before that, you should check for ground faults. Spilled acid is one of the main reasons for increasing nuisance trips of the built-in GFI. Could just need to rinse off the pack.

brucedp5 wrote: > 12VDC deep-cycle batteries do not last as long as 6V golf/traction > batteries. The latter have thicker plates= more lead. The latter part of this statement is no longer necessarily true; as the golf industry moved to 12V floodeds for their 48V cars, 12V flooded batteries became available that have the same plates as their 6V (and 8V) brethren (e.g. Trojan T1275 and US12VXC models). > The Zivan k & ng series chargers evolved into the series Elcon sells. This is incorrect; the Chinese-origin PFC chargers that Elcon sells began as clones of the Delta-Q charger and evolved from there. It is a bit confusing because Elcon was previously representing the Zivan product line, and so some mistakenly associate the Elcon-branded PFC chargers with Zivan. Note that the Elcon-branded PFC chargers will not have *any* regulatory approvals; any "CE" mark on them, if examined closely, will be found not to be the European (self-declaration, not 3rd-party inspected) regulatory mark, but a remarkably similar marking of no related meaning that is specific to China. This is one reason that the Delta-Q products are somewhat more expensive; internally they use approved insulation systems, etc. and are tested to comply with North American (and European and various other locale's) EMI, EMC, and safety agency standards. > The advantage is both of these charger brands are dual input voltage (they > run off either 120 or 240VAC).

Agreed; this is a definite reason to upgrade to a more modern, universal input charger model. Note that "dual voltage" chargers are probably best avoided, as this usually implies a (non-PFC) charger whose input automatically switches between a "120V" and "240V" setting based on the input line voltage, or one that must be manually switched between settings the by the user each time they plug into a different voltage source. Public (J1772 level 2) charging stations will be either 208V aor 240V, while an overnight charge at home will usually be from a 120V outlet; it could be fatal to a dual input charger if one forgot to switch it to the appropriate input voltage range before plugging in. > An alternative to the alternative ... > Way in the past, an evdl member poo-poo's my use of several individual > 12VDC chargers to charge my pack.

I won't poo-poo the idea, but I don't recommend the use of multiple chargers spanning a pack unless there really is no viable alternative. Aside from the reliability issue, the reality is that all commonly available 'fuel'/Ah/SOC gauges look only at overall pack voltage and overall pack current, and so can only ever account for the charge current/Ah of *one* of the N chargers spanning the pack. What invariably happens is that each charger delivers somewhat different current, and so unless one waits until *every* charger has completed, they will drive off with each section of their pack at a different SOC, and will only know the SOC of the single section that the gauge was monitoring the current for. The worst case is that one of the chargers fails (fuse opens, or wiring fault, or simply derates thermally because it is in a hot location, etc.) and the user discovers this only when that section of the pack runs flat (or reverses...) while they are driving. > I would order 8 of the 10A US models.

Be careful here: it is quite easy to end up with a bank of chargers whose input power requirements exceed what a common outlet can provide. At 2.4V/cell and 10A, each of these chargers would be outputting 144W; 1152W for 8 of them. They might only be 80% efficient, which brings the input power up to 1440W. This is right at the 12A that a 15A-rated 120V circuit can provide *IF* the voltage at the charger input is 120V. Usually, the outlet voltage is lower, and so the current drawn by the chargers will be higher. If they are not PFC, then the peak input current will be even higher than that estimated just by the power requirements. A bank of 8 of these ~might~ just squeak by on a 15A 120V circuit, but a 20A 120V circuit is probably a better choice. Opportunity charging on a 15A circuit would definitely be risky without knowing what else might be on the same

WALLACE — Now that the infrastructure is falling into place, Monte and Ruth Sheffield will be able to drive their new Tesla electric car more in Nebraska. When the Sheffields bought their first Tesla about 4½ years ago, they pushed the envelope just to get to Kearney and back. “That was right on the edge of the range of our first car,” Ruth said. Monte said the Hy-Vee in Kearney has an electric charger but it’s 220 volts and takes an hour to get 25 miles of charge. “So it’s really slow,” Monte said. “That’s what we have in our garage, but overnight it’s completely charged. When you’re sitting in Kearney at the Hy-Vee, an hour is enough.” Tesla has installed superchargers all across the country, most of which are on the West and East coasts. The Sheffields took a trip to California about two years ago. “When you charge it, there is no fee for using those chargers,” Monte said. “It’s all included in the price of the car. You pull in, plug in, charge, and there’s no credit-card transaction.” Now there are superchargers across Interstate 80, including in Sidney, Ogallala, Gothenburg, Grand Island, Lincoln and Omaha. “Our electric bills went up about $50 a month to charge the car,” Monte said. “When I charge here at home, for a dollar’s worth of electricity I can go 28 or 30 miles.” Ruth said Monte became interested in the Tesla after reading an article and has become “obsessed” with the car. “He just can’t get enough of learning about the technology and the car,” Ruth said. The base cost of a Tesla Model S, which is the model the Sheffields purchased, is about $70,000. “It’s really not that much more than a new SUV,” Ruth said. “And the cost to run it is much less.” The Tesla company continues to grow with battery technology, and it has created an electricity-storing product called the Powerwall that could change the way electricity is brought to rural areas.

Samsung will challenge Tesla with its own electric car batteries

With its claims of unprecedented power storage, Samsung plans to challenge
the electric car batteries now being pumped out of the Tesla Gigafactory.
Samsung has chosen a wise time to start building long-range car batteries:
China plans to ban gas-powered cars and automobile giant Volkswagen will
offer electric versions of all their vehicles by 2030.
These millions of forthcoming vehicles will need powerful batteries, and
earlier this week Samsung introduced its “multifunctional battery packs” at
the 2017 Frankfurt Motor Show, which it claims can power electric cars for
up to 430 miles. That would theoretically get you from Los Angeles to San
Francisco with about 50 miles to spare.
For reference, Tesla says that the recently released Model 3, its affordable
class vehicle, has batteries that can power the car for 220 miles.
The 200-mile difference between Tesla and Samsung sounds notable, but Tesla
batteries have been powering its electric vehicles for years, while
Samsung’s innovative offering has yet to hit the road. Without road-testing,
its unknown what type and size of electric vehicle will actually be able to
travel some 430 miles when powered by Samsung’s battery packs.
Although Samsung’s battery division, Samsung SDI, didn’t reveal too many
details about its multifunctional battery pack, it has some similarities
with the small, cylindrical batteries Tesla is putting into its Model 3,
called the 2170 battery cell. Currently being produced in Tesla’s sprawling
desert Gigafactory, these 2170 batteries can be held in the palm your hand,
and Elon Musk calls them the highest density battery cells in the world.
Samsung is apparently placing similar cylindrical batteries (called 21700
batteries) in book or block-like modules that increase the batteries energy
storage. In a press release, Samsung said that more of these battery-packed
modules can be added to a vehicle to increase the vehicle's driving range:
“Its users can change the number of modules as they want as if they
place books on a shelf. For example, if 20 modules are installed in a
premium car, it can go 600 to 700 kilometers. If 10 to 12 modules are
mounted on a regular sedan, it can run up to 300 kilometers.”
If a sedan-like electric vehicle can run 700 kilometers (430 miles) without
a charge, it will certainly prove a formidable challenge to Tesla’s electric
sedans. For now, however, Tesla’s batteries are powering cars on roads all
over the nation. And alongside these roads the company is strategically
placing Supercharger stations to power up cars in “a matter of minutes” —
for those taking their Teslas on trips across the country.

Can You Tune Electric Cars For More Power?

How Do Electric Cars Work? ...
]
It's all about the hardware.
The SLS AMG Electric Drive has four motors, one for each wheel, with total
power output at 526 bhp and 649 ft.-lb. of torque. With one gear delegating
the power, the E-Cell uses both regenerative braking and charging stations
to charge the batteries. Mercedes builds these to order, so don't expect to
see one on your local street. Or ever.
With the age of electric cars upon us, more and more people are wondering:
Can you tune them? Battery-powered cars don't use fuel or air to make
energy, meaning there's no obvious way to tinker with inputs and increase
power output. Or is there?
Jason Fenske of Engineering Explained [
https://www.youtube.com/channel/UClqhvGmHcvWL9w3R48t9QXQ
] put together a neat video laying out exactly how electric cars turn energy
into a rotating force, and how that force is used to spin the wheels. As for
if they can be tuned, Fenske tells us it's all about how much power each
component can withstand.
Upgrading the battery and software can only go so far until you run into
other limitations in the drivetrain, such as how fast the inverter can
operate and how quickly the car can translate its electric force into the
spinning motor. Of course, those things can be upgraded as well. So it's not
really about changing the software as much it is about upgrading hardware.
The video gets pretty technical, but describes the process of how electric
cars actually work impeccably well ...
