The TZ8J electric mixer truck is a practical electric truck for Jakarta's ready-mix concrete market, where high-rise and infrastructure projects need tight delivery windows and sites sit inside a congested 30 km radius. With a 350 kWh CATL LFP pack and a 360 kW motor it turns an 8 m3 drum across 200 to 260 km of range per charge, covering a full shift of plant-to-site runs.
Jakarta's air quality rules and the construction sector's push for greener sites make a zero-emission mixer attractive to developers bidding prestige towers. The TZ8J also removes diesel fumes from the site, a real safety gain where crews work around the rotating drum.
The TZ8J is a mixer chassis with a 350 kWh CATL LFP battery and a 360 kW drive motor, plus a separate inverter for the drum. The table below is the spec Indonesian buyers quote against when replacing diesel mixers.
| Parameter | TZ8J Value |
|---|---|
| Battery capacity | 350 kWh CATL LFP, liquid-cooled |
| Drive motor | 360 kW permanent-magnet motor |
| Drum volume | 8 m3 rated, 7 to 9 m3 configurable |
| Chassis layout | 6x4 mixer, 24 to 28 t payload |
| Certified range | 200 to 260 km per charge |
| DC fast charge | 240 / 360 kW (20 to 80 percent in 50 to 80 min) |
| Battery warranty | 8 years / 4,500 cycles |
| FOB price range | USD 115,000 to 145,000 |
Jakarta ready-mix plants sit on the city edge, with sites typically 8 to 25 km away. The TZ8J runs 10 to 14 deliveries per shift, each a short haul with the drum turning, then returns to plant to reload. The range comfortably covers the day because the drum inverter draws from the pack only while mixing, and regen on the return empty run tops the pack back up.
Because the plant is fixed, Fenghan installs a 360 kW DC charger on the batching yard so trucks charge during the mandatory 10-minute load and wash window. A two-gun unit serves a rotation of three to four TZ8J mixers, keeping the fleet moving without a dedicated charge shift.
Indonesian diesel near IDR 15,000 per liter and a 6x4 diesel mixer burning 30 L per 100 km costs about IDR 4,500 per km. The TZ8J at 1.6 kWh per km plus drum load and IDR 1,400 per kWh costs about IDR 2,240 per km in energy, a roughly 50 percent saving before maintenance.
| Cost (5 yr / 180,000 km) | Diesel mixer | TZ8J EV |
|---|---|---|
| Fuel / energy | IDR 8.10M | IDR 4.03M |
| Maintenance | IDR 1.60M | IDR 0.80M |
| Battery (pro-rata) | n/a | IDR 0.95M |
| Total | IDR 9.70M | IDR 5.78M |
Jakarta and Surabaya are tightening low-emission zones around government and prestige sites, and developers now ask for zero-emission concrete on green-certified towers. The TZ8J meets those requests directly, and its quiet operation reduces complaints from sites near homes. Indonesian demand for electric construction trucks is rising as total-cost cases like the table above reach fleet managers.
The TZ8J's 8 m3 drum turns off the dedicated inverter whenever the truck is moving, and slows to a gentle agitate at the site, so concrete quality holds without wasting pack energy. The control panel sets slump and batch ID, and the drum direction reverses for washdown, all from the cab touchscreen with no separate engine to warm up before the first pour.
Jakarta sites near homes and malls value the TZ8J's quiet drum and zero exhaust, which let it arrive before the 07:00 unlock without complaint. After the pour the automatic washdown reverses the drum and sprays the fins, keeping the unit within weight limits and ready for the next batch without a diesel-idle cleanup that would foul the site.
| Feature | Benefit |
|---|---|
| Quiet drum | Early-site access |
| Zero exhaust | Clean crew air |
| Auto washdown | Weight and hygiene compliance |
| Regen return | Free range on empty run |
The 350 kWh LFP pack shares a liquid loop with the motor and drum inverter, so on a 33 °C Jakarta day the cells stay in the 25 to 35 °C window. The plant charger pre-conditions the pack during the 10-minute load, so the first site run leaves with optimal cell temperature and the full 200 to 260 km range regardless of the morning heat.
A ready-mix plant running four TZ8J mixers on a 360 kW two-gun charger keeps all four in rotation through the morning peak, because each truck is only off the road for the 10-minute load plus a short charge. Fenghan models the batch rate against the charger guns so the plant never has trucks idle waiting for power instead of pouring.
At 1.6 kWh per km plus drum load and a typical Jakarta industrial rate, the TZ8J runs about half the energy cost of a diesel mixer, and maintenance is roughly half again. For a plant turning 200 batches per month, the combined saving typically recovers the FOB premium within 30 to 40 months while meeting the developer's green specification.
The TZ8J's LFP pack holds capacity well past the 8-year mark, so a unit rotated at 4 years typically retains 45 to 55 percent of FOB on the regional used market. That residual strength supports the finance case for a plant adding a second mixer, and Fenghan keeps the inspection record that proves battery health at trade-in. The drum and mixer driveline have few wear parts, so the used truck still commands a premium with ready-mix buyers who know the energy saving continues for the second owner.
Beyond the home plant, the TZ8J serves satellite batching yards in Bekasi and Depok, each within the 30 km comfort radius. Fenghan maps the plant-to-yard-to-site sequence so the drum never stands idle long enough for the slump to drift, and the 360 kW charger at each yard keeps the rotation tight. The quiet operation also lets the mixer serve night pours in dense districts that ban diesel noise after 22:00, opening a shift window the competition cannot use.
Indonesian buyers land at Tanjung Priok and process under the CKD and CBU vehicle rules, with EV import discussion active. Fenghan manages export packing, marine insurance, and plant-side commissioning including charger install.
