- Where's the next charging station?
How do you say Charging Station?
The cities are a different universe
But occupy one-hundreth-of-one-percent of the land area. - Nice Page Mex.

Does the battery pack itself have a diagnostic port? I likely wouldn't be dealing with one still in the automobile.
That’s a good point...and the answer is I don’t know. I look forward to following your project.- Does the battery pack itself have a diagnostic port? I likely wouldn't be dealing with one still in the automobile.

Definitely not something to take lightly, and without some technical understanding.
If I were to do it:
1. The pack would be fully disassembled, down to it's smallest module size.
2. Each module would be checked to see if it's in-spec in terms of voltage, and for signs of physical damage.
3. Each module would be charged stand-alone, outdoors, to full capacity, and then drained to 20%
4. Modules would be assembled to achieve target voltage / current, and then charged as a pack, outdoors, and then drained, as a pack to 20%
5. A BMS with over discharge, over charge and temperature monitoring would be employed.
Only then would I be comfortable putting pack built from a wreck into service.
If it is a leaf battery a lot of those checks can be done with Leaf Spy software and the obd port. Lots of leaf owners do this with their leafs. (not me, I just drive the heck out of it :) )GordonThree wrote:

This is what Juan did when he got the battery out of its casing. Tested all 48, later 49, modules, and found that all were good. He is meticulous in his research and found out all about this =before= he even bought a battery. After running more calcs, he decided that he needed to add that 49th module to make the voltages work out correctly. It's all documented in his blog posts.
Also, Juan told me that part of the competition for these batteries is from off-gridders in S&B houses looking for inexpensive battery banks.
Lyle- Puebla, a million plus city in Central Mexico just started selling made-in-Mexico electric cars. Details unknown. Needs research.
Production of Mexican-owned Zacua electric car set to begin in Puebla
One car a day will roll off the production line at the women-only plant

Production of the first electric cars made in Mexico by a 100% Mexican-owned company will begin in Puebla next week after a new Zacua plant was officially opened yesterday.
CEO Jorge Martínez Ramos said during the ceremony that the plant — located in the state capital’s Puebla 2000 Industrial Park — will manufacture 100 M2 and M3 two-seater, zero-emission Zacua coupe models in its first year of operation and initially generate 35 direct jobs.
The 80-million-peso (US $4.3-million) plant’s output is expected to double in its second year of production and a four-seater model will be added to the company’s lineup.
Eventually, Zacua’s goal is to manufacture 2,000 vehicles annually at the Puebla facility, for which an additional 500-million-peso (US $26.8-million) investment will be required.
The first cars are set to go on sale next month and will retail for around 550,000 pesos (US $29,500).
The vehicles’ entry into the market was initially slated for November but the company experienced delays following the September 19 earthquake.
The two models will come in three colors — red, ivory and gray — and sales will initially be made via the Zacua website. Only women will work in the Puebla plant, where they will assemble one vehicle per day using 40% locally-supplied content.
However, starting on December 1 next year the company aims to use 100% Mexican content.
Spanish company Dynamik Technological Alliance completed the vehicles’ engineering development and French company Chatenet was responsible for the design but Zacua intends to use a completely Mexican design for new models it develops.
Measuring just 3.06 meters in length, 1.56 meters wide and 1.4 meters high and weighing 685 kilograms, the car is designed to squeeze into the smallest of spaces.
Each vehicle will have a lithium-ion battery that takes eight hours to fully charge and allows a range of 160 kilometers or just under 100 miles.
Only women are employed at the new factory.
Only women are employed at the new factory.
The cars will be capable of reaching a maximum speed of 95 km/h although Mexico City drivers will be limited to a top speed of 85 km/h.
The new electric cars will not be restricted by the Hoy No Circula (No Circulation Today) regulation in the capital nor will owners have to pay vehicle tax or purchase an environmental verification certificate.
Other vehicle specifications include:
An electric permanent magnet synchronous motor with a maximum power output of 34 kilowatts.
Front-wheel drive.
Hydraulic circuit ABS braking system.
MacPherson Strut-style suspension.
Puebla Governor José Antonio Gali Fayed welcomed the company’s arrival at yesterday’s plant opening and said that the Zacua vehicles will help to reduce Mexico’s overall carbon emissions. ependydad wrote:
