Electric Construction Machinery Is Here — Will the Used Market Change?

November 6th, Changzhou warehouse. Three 2022 electric loaders parked in the lot; the seller was in a hurry, quoting just 60% of same-year diesel machines.

I circled the machines three times, read materials for two weeks — and still didn't dare take them.

Not because the machines were bad. Because I can't test a battery.

The seller chased me three times, conceding more each round. The more he conceded, the less I dared touch them.

An old truth of this trade: when the seller is more anxious than you, the machine usually hides problems you can't see.

Electric machines really are multiplying

The year before last, electric excavators and loaders were still rare on domestic sites. This year I toured Jiangsu and Shandong — the electric share in ports and steel mills is visibly up.

I don't fully trust manufacturers' data, but I trust my own eyes: in November alone, nine new and old customers asked whether we buy electric machines.

Of those nine, six wanted to sell us their machines, three asked whether we'd take them in future trade-ins. Wanting to buy: zero.

Diesel won't disappear, but the used pool will hold more and more electrics in two or three years. That's a visible trend.

When it comes, whoever can test batteries eats first. Whoever can't won't even dare quote a price.

The biggest problem now: no residual-value standard. Diesel machines anchor on hours and year; electrics have neither. Same machine, battery swapped or not — a difference of a hundred thousand-plus yuan, and nobody can certify it.

Manufacturers push battery-swap and buy-back policies, but only for machines from their own channels. Battery standards in the used-circulation link are a vacuum right now.

The wall called battery degradation

Diesel engines I know. Hours, sound, cylinder pressure, pull the oil pan and look for shavings — condition nailed within ten percent.

Batteries, no. State of health is one number in the manufacturer's software; actual degradation is another matter.

I tested those three Changzhou machines: on a full charge the dash showed eight hours of range; actually working under load, it alarmed at five. Nearly 40% degraded.

The seller said the dash was fine. Of course the dash is fine — it reads the battery's report card, not the battery's body.

What does a battery pack cost? I asked the manufacturer: 180,000 yuan. The whole used machine is only quoted at three hundred thousand-odd.

Buy an electric machine, then pay half its price again for a battery — that deal doesn't work.

Later I consulted engineers at a battery maker and learned two tricks. One: charge-cycle count — past 1,500 cycles, degradation is basically irreversible. Two: cell voltage spread — after a full charge and an overnight rest, a spread over 0.1 volt between cells means a bad apple in the pack.

These two tricks filter out the obviously bad machines, but not the latent faults. So same as ever: no complete test report, no deal.

The tuition I've paid

This March I bought an electric forklift, figuring a small battery meant small risk.

Two days of testing at purchase — normal. Sold to a Foshan customer; four months in, two cells in the pack died and the whole pack went down.

A replacement battery: 19,000 yuan, all on me. The customer didn't blame me, but I wrote it down for myself: battery faults have incubation periods that short tests can't catch.

Nineteen thousand — my first tuition payment for electrification. Every payment after it has to be smaller.

How to keep them smaller? Start small. Forklifts and compact loaders first — small batteries, cheap parts — build the feel before touching big machines.

After March's loss, I added a line to every electric-machine inspection sheet: the battery section gets its own page and its own signature. Whoever tests it owns it.

Impact on the export business

African customers aren't buying electrics now — not because they don't want them, but because they don't dare.

Sites have no chargers, grids are unstable, and nobody local can fix them. Mohammed put it to me plainly: "Chen, a diesel engine I can fix. A battery I can only worship."

The Middle East and Southeast Asia are in better shape, but parts and service networks haven't caught up either.

A customer in the UAE asked about electric loaders, then did his own math after we talked: building charging infrastructure on site would cost more than the fuel savings. He dropped it.

So for the next five years, diesel remains the backbone of used exports. That call I'll put in writing.

After five years? Watch where charging piles get built and whether battery testing standards get established. Once standards exist, we enter anytime.

How we're preparing

First, learn. Next month Lao Li goes to a battery plant for a week of training on pack testing — 12,000 yuan in tuition and travel, on the company.

Second, buy equipment. A battery internal-resistance tester and a charge-discharge test cabinet, 70,000-odd together, in place by Q1 next year.

Third, set the rule: only buy electrics with complete battery test reports. No report, no deal at any price.

The timeline is set too: in H1 next year, a pilot of no more than three machines — electric forklifts and compact loaders. Sell them, follow them for six months, record the data. Once enough data piles up, then we talk about electric excavators.

When Lao Li comes back from training, he'll teach two sessions for me and the whole warehouse crew. The tuition can't pay back for just one person.

I plan to compile the courseware and send it to old customers. If they can read batteries, they step in fewer pits — and our machines sell steadier for it.

What you don't understand, you don't touch; enter when you do. The survivors in this trade all share that temper.
